What’s the difference between MSG and table salt? A chemist explains

<a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> It’s dinner time. You’ve worked hard to prepare a nutritious and tasty meal. But after taking your first bite you feel something is missing. Perhaps you should have added more salt? Pepper? Or maybe even something more exotic like monosodium glutamate, better known as MSG? There are many <a href="https://theconversation.com/explainer-what-are-e-numbers-and-should-you-avoid-them-in-your-diet-43908">food additives</a> used in both home cooking and commercial products. These ingredients improve the flavour, smell, texture, appearance and longevity of foods. Salt and MSG are two well-known food additives. Both contain sodium, but there are plenty of differences which you can use to your benefit. <h2>What is a salt?</h2> Salts are made of positively and negatively charged components called ions. Salts generally dissolve in water, and are brittle. The names of salts often feature a metal (positively charged) followed by a non-metal (negatively charged). The common kitchen ingredient we call “salt” is just one type of salt. To distinguish it from all other salts, we should more specifically refer to it as “table salt”. Chemically, it’s sodium chloride. <h2>Sodium chloride</h2> After the quick chemistry lesson above, we can see that table salt, sodium chloride, contains a positively charged sodium and a negatively charged chlorine. These charged components are arranged in crystals of salt in a regular repeating pattern. Each sodium ion is surrounded by six chloride ions and each chloride ion is surrounded by six sodium ions. This arrangement gives the crystal a “cubic” form. If you look closely at salt, you may see cube-shaped crystals. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=600&fit=crop&dpr=1 600w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=600&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=600&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=754&fit=crop&dpr=1 754w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=754&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=754&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>The chemical structure of table salt forms a cube of sodium and chloride ions. <a class="source" href="https://www.shutterstock.com/image-vector/sodium-chloride-nacl-structure-ionic-crystal-2417242373">Sandip Neogi/Shutterstock</a></figcaption></figure> Sodium chloride is very abundant. It is found <a href="https://theconversation.com/i-have-always-wondered-why-is-the-sea-salty-83489">dissolved in Earth’s oceans</a>. Mineral deposits of salt, known as halite or rock salt, formed from the evaporation and crystallisation of ancient seas. Depending on the source, the salt may contain many other trace minerals that can even add colour to it, such as the pink-coloured Himalayan salt from Pakistan. Salt can also be fortified with <a href="https://www.who.int/publications/i/item/9789240053717">sodium iodide</a> as a public health measure. Describing the taste of salt is quite difficult without using the word “salty”. It’s a very common food additive, as it is so abundant and versatile. It is an essential ingredient for many traditional food preservation techniques for meats (pork and fish), vegetables (kimchi, sauerkraut and pickles), and dairy (cheese and butter). Salt is considered a universal flavouring agent. It can mask bitter flavours and bring out sweet, sour and <a href="https://theconversation.com/the-asian-roots-of-umami-the-fifth-taste-central-to-thanksgiving-fare-50699">umami</a> (savoury) ones. Despite popular depictions of <a href="https://theconversation.com/that-neat-and-tidy-map-of-tastes-on-the-tongue-you-learned-in-school-is-all-wrong-44217">taste maps</a>, there is no one place on the tongue where we taste salt. Other sodium salts can also give a “salty” taste, but the effect declines (and can even turn to bitter) with negatively charged components other than chloride. <h2>MSG or monosodium glutamate</h2> Monosodium glutamate is also a salt. The glutamate is the negatively charged form of glutamic acid, an amino acid that is found in nature as a building block of proteins. MSG, and more generally glutamates, are found in a wide range of foods including tomatoes, Parmesan cheese, soy sauce, dried seaweeds, Worcestershire sauce and protein-rich foods. All of these foods impart umami flavours, which are described as savoury or meaty. Commercial MSG is not extracted from the environment but produced by bacterial fermentation. Glucose is converted to glutamic acid, which is further processed by adding sodium hydroxide to form MSG (and water). MSG is sold as crystals, but they have a long, prismatic shape rather than the cubic form of sodium chloride. It’s worth tasting a few crystals of MSG directly to experience the native taste of umami. Despite decades of bad press and concern, <a href="https://theconversation.com/msg-is-back-is-the-idea-its-bad-for-us-just-a-myth-or-food-science-237871">MSG is considered safe</a> to consume in the concentrations typically found in or added to foods. Table salt and MSG both contain sodium, but at different percentages of the total weight: table salt has around 40% sodium, versus just 14% in MSG. You are also more likely to be routinely adding table salt to your food rather than MSG. Eating too much sodium is well known to be unhealthy. <a href="https://theconversation.com/this-salt-alternative-could-help-reduce-blood-pressure-so-why-are-so-few-people-using-it-221409">Potassium-enriched substitutes</a> have been suggested for a range of health benefits. <h2>A flavour enhancer</h2> The flavour of MSG can be elevated further by combining it with other food additives, known as sodium ribonucleotides. Japanese and Korean cooks figured this secret out long before chemists, as boiling dried fish and seaweed produces foundation stocks (dashi) containing a mix of naturally sourced glutamates and ribonucleotides. Ribonucleotides are classified as “generally considered as safe” by <a href="https://www.cfsanappsexternal.fda.gov/scripts/fdcc/index.cfm?set=FoodSubstances&id=DISODIUMINOSINATE&sort=Sortterm_ID&order=ASC&startrow=1&type=basic&search=disodium">food standards authorities</a>. Humans consume many grams of the natural equivalent in their diets. What can be more problematic are the carbohydrates- and fat-rich foods that have their flavours enhanced, which can potentially lead us to eat excessive calories. The combination of MSG and ribonucleotides produces a more-ish sensation. Next time you see a bag of potato chips or instant noodles, have a quick look to see if it contains both MSG (E621) and a ribonucleotide source (E627–E635). I personally keep a jar of MSG in my kitchen. A little goes a long way to elevate a soup, stew or sauce that isn’t quite tasting the way you want it to, but without adding too much extra sodium.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237668/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

<a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike. Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog. I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets. <h2>Breed and age differences</h2> Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia. Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat. Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather. <h2>When is my dog too cold?</h2> Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable. Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>. Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog. Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it. <h2>Road salt dangers</h2> Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws. Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs. Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation. <h2>Antifreeze risks</h2> <a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing. Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>. There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment. When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible. Try some <a href="https://www.akc.org/expert-advice/lifestyle/great-indoor-games-to-play-with-your-dog/">indoor activities</a>, like hide-and-seek with low-calorie treats, fetch or even an interactive obstacle course. Food puzzles can also keep your dog mentally engaged during indoor time. Although winter presents some unique challenges, it can still be an enjoyable and healthy time for you and your canine companion.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/221709/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, Health Sciences Assistant Professor of Clinical Veterinary Medicine, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Family & Pets

I want to eat healthily. So why do I crave sugar, salt and carbs?

<a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> We all want to eat healthily, especially as we reset our health goals at the start of a new year. But sometimes these plans are sabotaged by powerful cravings for sweet, salty or carb-heavy foods. So why do you crave these foods when you’re trying to improve your diet or lose weight? And what can you do about it? There are many reasons for craving specific foods, but let’s focus on four common ones: <h2>1. Blood sugar crashes</h2> Sugar is a key energy source for all animals, and its taste is one of the most basic sensory experiences. Even without specific sweet taste receptors on the tongue, a strong preference for sugar can develop, indicating a mechanism beyond taste alone. Neurons <a href="https://www.nature.com/articles/s41593-021-00982-7">responding to sugar</a> are activated when sugar is delivered to the gut. This can increase appetite and make you want to consume more. Giving into cravings also drives an appetite for more sugar. In the long term, research suggests a high-sugar diet can affect <a href="https://www.bmj.com/content/369/bmj.m2382">mood</a>, digestion and <a href="https://pubmed.ncbi.nlm.nih.gov/33339337/">inflammation</a> in the <a href="https://www.science.org/doi/10.1126/scitranslmed.aay6218?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">gut</a>. While there’s a lot of <a href="https://www.sciencedirect.com/science/article/pii/S0149763402000040?via%3Dihub#aep-section-id23">variation between individuals</a>, regularly eating sugary and high-carb foods can lead to <a href="https://pubmed.ncbi.nlm.nih.gov/30951762/">rapid spikes and crashes</a> in blood sugar levels. When your blood sugar drops, your body can respond by craving quick sources of energy, often in the form of sugar and carbs because these deliver the fastest, most easily accessible form of energy. <h2>2. Drops in dopamine and serotonin</h2> Certain neurotransmitters, such as <a href="https://pubmed.ncbi.nlm.nih.gov/30595479/">dopamine</a>, are involved in the reward and pleasure centres of the brain. Eating sugary and carb-rich foods can trigger the release of dopamine, creating a pleasurable experience and reinforcing the craving. Serotonin, the feel-good hormone, suppresses <a href="https://www.sciencedirect.com/science/article/pii/S1569733910700886">appetite</a>. Natural changes in serotonin can influence daily fluctuations in mood, energy levels and attention. It’s also associated with eating more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5829131/">carb-rich snacks in the afternoon</a>. <a href="https://pubmed.ncbi.nlm.nih.gov/21985780/">Low carb diets</a> may reduce serotonin and lower mood. However, a recent systematic review suggests little association between these diets and risk for <a href="https://www.sciencedirect.com/science/article/pii/S0165032722013933?via%3Dihub">anxiety and depression</a>. Compared to men, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4189179/">women tend to crave more carb rich foods</a>. Feeling irritable, tired, depressed or experiencing carb cravings are part of premenstrual <a href="https://pubmed.ncbi.nlm.nih.gov/29218451/">symptoms</a> and could be <a href="https://www.ncbi.nlm.nih.gov/books/NBK560698/">linked to</a> reduced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9928757/">serotonin levels</a>. <h2>3. Loss of fluids and drops in blood sugar and salt</h2> Sometimes our bodies crave the things they’re missing, such as hydration or even salt. A low-carb diet, for example, <a href="https://www.ncbi.nlm.nih.gov/books/NBK537084/">depletes</a> insulin levels, decreasing sodium and water retention. <a href="https://www.sciencedirect.com/science/article/pii/S1933287419302673">Very low-carb diets</a>, like ketogenic diets, induce “ketosis”, a metabolic state where the body switches to using fat as its primary energy source, moving away from the usual dependence on carbohydrates. Ketosis is often associated with increased urine production, further contributing to potential fluid loss, electrolyte imbalances and salt cravings. <h2>4. High levels of stress or emotional turmoil</h2> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214609/">Stress</a>, boredom and emotional turmoil can lead to cravings for comfort foods. This is because stress-related hormones can impact our appetite, satiety (feeling full) and food preferences. The stress hormone <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425607/">cortisol</a>, in particular, can drive cravings for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">sweet comfort foods</a>. A <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">2001 study</a> of 59 premenopausal women subjected to stress revealed that the stress led to higher calorie consumption. <a href="https://pubmed.ncbi.nlm.nih.gov/37295418/">A more recent study</a> found chronic stress, when paired with high-calorie diet, increases food intake and a preference for sweet foods. This shows the importance of a healthy diet during stress to prevent weight gain. <h2>What can you do about cravings?</h2> Here are four tips to curb cravings: 1) don’t cut out whole food groups. Aim for a well-balanced diet and make sure you include: <ul> <li> sufficient protein in your meals to help you feel full and reduce the urge to snack on sugary and carb-rich foods. Older adults should aim for 20–40g protein per meal with a particular focus on <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/jhn.12838">breakfast and lunch</a> and an overall daily protein intake of at least <a href="https://apps.who.int/iris/handle/10665/43411">0.8g</a> per kg of body weight for <a href="https://pubmed.ncbi.nlm.nih.gov/35187864/">muscle health</a> </li> <li> fibre-rich foods, such as vegetables and whole grains. These make you feel full and <a href="https://pubmed.ncbi.nlm.nih.gov/32142510/">stabilise your blood sugar</a> levels. Examples include broccoli, quinoa, brown rice, oats, beans, lentils and bran cereals. Substitute refined carbs high in sugar like processed snack bars, soft drink or baked goods for more complex ones like whole grain bread or wholewheat muffins, or nut and seed bars or energy bites made with chia seeds and oats </li> </ul> 2) manage your stress levels. Practise stress-reduction techniques like meditation, deep breathing, or yoga to manage emotional triggers for cravings. Practising <a href="https://pubmed.ncbi.nlm.nih.gov/30570305/">mindful eating</a>, by eating slowly and tuning into bodily sensations, can also reduce daily calorie intake and curb cravings and stress-driven eating 3) get enough sleep. Aim for <a href="https://pubmed.ncbi.nlm.nih.gov/33054337/">seven to eight</a> hours of quality sleep per night, with a minimum of seven hours. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9031614/">Lack of sleep</a> can disrupt hormones that regulate hunger and cravings 4) control your portions. If you decide to indulge in a treat, control your portion size to avoid overindulging. Overcoming cravings for sugar, salt and carbs when trying to eat healthily or lose weight is undoubtedly a formidable challenge. Remember, it’s a journey, and setbacks may occur. Be patient with yourself – your success is not defined by occasional cravings but by your ability to manage and overcome them.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/212114/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, Assistant Professor, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Slashing salt can save lives – and it won’t hurt your hip pocket or tastebuds

<a href="https://theconversation.com/profiles/peter-breadon-1348098">Peter Breadon</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/lachlan-fox-1283428">Lachlan Fox</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> Each year, more than <a href="https://www.aihw.gov.au/getmedia/eb5fee21-7f05-4be1-8414-8b2bba7b4070/ABDS-2018-Risk-factor-supp-data-tables.xlsx.aspx">2,500 Australians</a> die from diseases linked to eating too much salt. We shouldn’t be putting up with so much unnecessary illness, mainly from heart disease and strokes, and so many deaths. As a new <a href="https://grattan.edu.au/report/sneaky-salt/">Grattan Institute report</a> shows, there are practical steps the federal government can take to save lives, reduce health spending and help the economy. <h2>We eat too much salt, with deadly consequences</h2> Eating too much salt is bad for your health. It <a href="https://www.nature.com/articles/s41569-018-0004-1">raises blood pressure</a>, which increases the risk of <a href="https://www.ahajournals.org/doi/full/10.1161/HYPERTENSIONAHA.119.14240">heart disease and stroke</a>. About <a href="https://www.aihw.gov.au/reports/risk-factors/high-blood-pressure/contents/summary">one in three</a> Australians has high blood pressure, and eating too much salt is the biggest individual contributor. Unfortunately, the average Australian eats far too much salt – <a href="https://onlinelibrary.wiley.com/doi/abs/10.5694/mja17.00394">almost double</a> the recommended daily maximum of 5 grams, equivalent to <a href="https://www.heartfoundation.org.au/sodium-and-salt-converter#:%7E:text=We%20recommend%20adults%20eat%20less,about%201%20teaspoon%20a%20day">a teaspoon</a>. Australian governments know excessive salt intake is a big problem. That’s why in <a href="https://www.health.gov.au/resources/publications/national-preventive-health-strategy-2021-2030?language=en">2021 they set a target</a> to reduce salt intake by at least 30% by 2030. It’s an ambitious and worthy goal. But we’re still eating too much salt and we don’t have the policies to change that. <h2>Most of the salt we eat is added to food during manufacturing</h2> Most of the salt Australians eat doesn’t come from the shaker on the table. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7231587/">About three-quarters</a> of it is added to food during manufacturing. This salt is hidden in everyday staples such as bread, cheese and processed meats. Common foods such as ready-to-eat pasta meals or a ham sandwich can have up to half our total recommended salt intake. <h2>Salt limits are the best way to cut salt intake</h2> Reducing the amount of salt added to food during manufacturing is the most effective way to reduce intake. Salt limits can help us do that. They work by setting limits on how much salt can be added to different kinds of food, such as bread or biscuits. To meet these limits, companies need to change the recipes of their products, reducing the amount of salt. Under salt limits, the United Kingdom reduced salt intake <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.120.16649">by 20% in about a decade</a>. <a href="https://www.nature.com/articles/s41371-021-00653-x">South Africa</a> is making even faster gains. Salt limits are cheap and easy to implement, and can get results quickly. Most consumers won’t notice a change at the checkout. Companies will need to update their recipes, but even if all the costs of updating recipes were passed on to shoppers, we calculate that at most it would cost about 10 cents each week for the average household. Nor will consumers notice much of a change at the dinner table. <a href="https://www.mdpi.com/2072-6643/6/10/4354">Most people don’t notice</a> when some salt is removed <a href="https://www.sciencedirect.com/science/article/pii/S0022316622031224">from common foods</a>. There are many ways companies can make foods taste just as salty without adding as much salt. For example, they can make <a href="https://www.wsj.com/articles/SB10001424052748704534904575131602283791566">salt crystals finer</a>, or use <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4520464/">potassium-enriched salt</a>, which swaps some of the harmful sodium in salt for potassium. And because the change will be gradual, our tastebuds will <a href="https://doi.org/10.1093/eurjcn/zvac060.077">adapt to less salty foods</a> over time. <h2>Australia’s salt limits are failing</h2> Australia has had voluntary salt limits since 2009, but they are badly designed, poorly implemented, and have reduced population salt intake by just <a href="https://www.abs.gov.au/articles/healthy-food-partnership-reformulation-program-two-year-progress">0.3%</a>. Because Australia’s limits are voluntary, many food companies have chosen not to participate in the scheme. Our analysis shows that 73% of eligible food products are not participating, and only 4% have reduced their salt content. <h2>Action could save lives</h2> Modelling from the University of Melbourne <a href="https://mspgh.unimelb.edu.au/__data/assets/pdf_file/0004/4783405/The-Health-and-Cost-Impacts-of-Sodium-Reduction-Interventions-in-Australia.pdf">shows</a> that fixing our failed salt limits could add 36,000 extra healthy years of life, across the population, over the next 20 years. This would delay more than 300 deaths each year and reduce health-care spending by A$35 million annually, the equivalent of 6,000 hospital visits. <a href="https://www.nature.com/articles/jhh2013105">International experience</a> <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.120.16649">shows</a> the costs of implementing such salt limits would be very low and far outweighed by the benefits. <h2>How to fix our failed salt limits</h2> To achieve these gains, the federal government should start by enforcing the limits we already have, by making compliance mandatory. <a href="https://www.sciencedirect.com/science/article/abs/pii/S216183132300042X">Fifteen countries</a> have mandatory salt limits, and 14 are planning to introduce them. The number of foods covered by salt limits in Australia should more than double, to be as broad as those the <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/604338/Salt_reduction_targets_for_2017.pdf">UK set in 2014</a>. Broader targets would include common foods for which Australia does not currently set targets, such as baked beans, butter, margarine and canned vegetables. A loophole in the current scheme that lets companies leave out a fifth of their products should be closed. The federal government should design the policy, rather than doing it jointly with industry representatives. Over the coming decades, Australia will need many new and improved policies to reduce diet-related disease. Reducing salt intake must be part of this agenda. For too long, Australia has let the food industry set the standard, with almost no progress against a major threat to our health. Getting serious about salt would save lives, and it would more than pay for itself through reduced health-care costs and increased economic activity.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/213980/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/peter-breadon-1348098">Peter Breadon</a>, Program Director, Health and Aged Care, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/lachlan-fox-1283428">Lachlan Fox</a>, Associate, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

This eating habit could knock two years off your life

Adding extra salt to your food could be placing you at a higher risk of dying prematurely according to a recent study of more than 50,000 people. Though seasoning food is a must for most of us, the <a href="https://doi.org/10.1093/eurheartj/ehac208" target="_blank" rel="noopener">study found</a> that those who added salt to their food had a 28 percent greater risk of dying prematurely than those who never or rarely add salt. With about 3 percent of people aged between 40-69 years old dying prematurely - defined as dying before the age of 75 - the findings suggest that adding salt could result in an extra one person in every hundred dying prematurely in this age group. “To my knowledge, our study is the first to assess the relation between adding salt to foods and premature death,” said Professor Lu Qi, one of the lead researchers from Tulane University School of Public Health and Tropical Medicine in New Orleans. The team also found that at the age of 50, those who always added salt to their food had between 1.5 to two years knocked off their life expectancy in comparison to those who rarely or never added any salt. “It provides novel evidence to support recommendations to modify eating behaviours for improving health,” Professor Qi continued. “Even a modest reduction in sodium intake, by adding less or no salt to food at the table, is likely to result in substantial health benefits, especially when it is achieved in the general population.” When it came to determining sodium intake, the team chose to focus solely on whether people added salt to their food at the table, independent of whether they seasoned it while cooking. This is because assessing how much sodium a person consumes is notoriously difficult, given that pre-prepared and processed foods are among many products where high levels of salt have been added before they reach the table. Plus, foods that are high in sodium are often accompanied by others that are rich in potassium, which protects against the risks of heart disease and metabolic diseases such as diabetes. “Adding salt to foods at the table is a common eating behaviour that is directly related to an individual’s long-term preference for salty-tasting foods and habitual salt intake,” Professor Qi explained. “In the Western diet, adding salt at the table accounts for 6-20 percent of total salt intake and provides a unique way to evaluate the association between habitual sodium intake and the risk of death.” However, their study does have limitations. With no information about the amount of salt added, the possibility of a relationship between adding salt and total energy intake and consuming other foods, and the voluntary nature of the UK BioBank meaning that the results aren’t reflective of a general population, more studies will need to be done to validate their findings. Professor Qi and his colleagues will be conducting additional studies on the relationship between adding salt to food and chronic diseases such as cardiovascular disease and diabetes, with the possibility of conducting clinical trials to test the effects of salt reduction. In <a href="https://academic.oup.com/eurheartj/article-lookup/doi/10.1093/eurheartj/ehac336" target="_blank" rel="noopener">an editorial</a> accompanying the study, Professor Annike Rosengren, a senior researcher and professor of medicine at the University of Gothenburg, Sweden, who wasn’t involved in the research, wrote that the net effect of drastic reduction in salt intake is still controversial for individuals. “Given the various indications that a very low intake of sodium may not be beneficial, or even harmful, it is important to distinguish between recommendations on an individual basis and actions on a population level,” she writes. With a greater net benefit likely to come from population-wide changes that have a small effect on individuals rather than targeted changes for high-risk people, Professor Rosengren argues that not adding extra salt “could contribute to strategies to lower population blood pressure levels”, including early detection and treatment of hypertension, as well as salt-reduction at a societal level. Professor Qi’s study and Professor Rosengren’s editorial were published in the European Heart Journal. Image: Getty Images

Salt substitute leads to fewer strokes and heart attacks

<div class="copy"> A reduced-sodium, potassium-rich ‘salt substitute’ reduces rates of stroke, heart attack and death, according to a new <a rel="noreferrer noopener" href="https://doi.org/10.1056/NEJMoa2105675" target="_blank">study</a> published in The New England Journal of Medicine. Researchers from the George Institute for Global Health showed that a salt substitute with more potassium chloride and less sodium chloride – the ‘normal’ table salt – leads to lower blood pressure and reduced heart problems, with no harmful effects. “Almost everyone in the world eats more salt than they should,’’ says lead author Bruce Neal. “Switching to a salt substitute is something that everyone could do if salt substitutes were on the supermarket shelves. “Better still, while salt substitutes are a bit more expensive than regular salt, they’re still very low-cost – just a few dollars a year to make the switch. “As well as showing clear benefits for important health outcomes, our study also allays concerns about possible risks. We saw no indication of any harm from the added potassium in the salt substitute. Certainly, patients with serious kidney disease should not use salt substitutes, but they need to keep away from regular salt as well.” The study was conducted with 21,000 adults with a history of stroke or blood-pressure issues from 600 rural Chinese villages in 2014/15. For those using the low-sodium salt, the team found that incidents of stroke dropped by 14%, total cardiovascular events (including heart attack) dropped by 13% and premature deaths dropped by 12%. They also showed that the price difference between table salt and the substitute was low – $1.48 per kilogram for regular salt compared to $2.22 per kilogram for low-sodium salt. ‘’Last year, a modelling study done for China suggested that about 400,000 premature deaths might be prevented each year by national uptake of salt substitute,” says Neal. “Our results now confirm this. If salt was switched for salt substitute worldwide, there would be several million premature deaths prevented every year. “This is quite simply the single-most worthwhile piece of research I’ve ever been involved with. Switching table salt to salt substitute is a highly feasible and low-cost opportunity to have a massive global health benefit.” Because of this result, the researchers have urged salt manufactures to switch to low-sodium salt, and for governments to make policies that promote salt substitutes.

Red Cross nurse accused of switching vaccines for salt solution

Northern German authorities are contacting thousands of people and informing them to get another COVID-19 jab after an investigation uncovered that a Red Cross nurse may have injected them with a saline solution. The nurse has been suspected of injecting salt solution into people's arms instead of a real dose at a vaccination centre in Friesland, a district near the North Sea Coast. "I am totally shocked by this episode," Sven Ambrosy, a local councillor, said on Facebook. Local authorities are in the process of contacting over 8,600 residents who may have been affected. <img style="width: 500px; height:281.25px;" src="https://oversixtydev.blob.core.windows.net/media/7836313/vaccine.jpg" alt="" data-udi="umb://media/1e3453d989304150b35c9bbfb0e97893" /> Image: Shutterstock Saline solution is harmless, however many people who got vaccinated in Germany in March and April are elderly people at high risk of catching the deadly viral disease. Sadly, the time frame that a majority of elderly people received the jab, coincides with when the nurse is suspected to have switched the vaccines. Police investigator Peter Beer, told German media that there is "a reasonable suspicion of danger". The nurse, who remains anonymous for now, made it clear on social media that she was sceptical of vaccines in social media posts, police investigators said.

How to make Jamie Oliver's bay salt prawn skewers with summer veg

Time to prepare 25 mins | Serves 4 Warmer weather brings memories of sun, seafood and barbeques - so why not combine them all? This recipe from Jamie Oliver puts a yummy twist on the good ol' shrimp. The bay salt flavour is unconventional but that's what makes this BBQ prawn recipe taste so delicious. Recipe from <a href="http://www.jamieoliver.com/recipes">jamieoliver.com/recipes</a> Ingredients: <ul> <li>20 raw king prawns, from sustainable sources (ask your fishmonger), peeled and black veins removed</li> <li>4 small courgettes</li> <li>10 bay leaves</li> <li>1 tablespoon sea salt</li> <li>3 tablespoons good extra virgin olive oil</li> <li>Juice of ½ lemon</li> <li>2 large handfuls freshly podded peas</li> <li>2 large handfuls freshly podded broad beans</li> <li>1 small bunch fresh mint, leaves picked\</li> <li>A few chive flowers, optional</li> <li>Sea salt</li> <li>Freshly ground black pepper</li> </ul> Directions 1. First of all, get your barbecue good and hot. If you're using wooden skewers, soak four of them in some cold water for 10 minutes, so they don't burn when you put them on the barbie later. Thread 5 prawns on to each skewer, make sure you poke through the fat and the thin part of each prawn. Slice the courgettes into ribbons with a speed peeler or a mandolin. 2. To make the bay salt, crumble the bay leaves into a pestle and mortar and add the salt. Bash up the bay leaves until you have a vibrant green salt and all the bay leaves have broken down and released their natural oils. 3. Sprinkle each of the prawn kebabs with a good pinch of the bay salt. Drizzle them with a little olive oil and pat and rub everything in. Place the skewers on the hot barbecue for a couple of minutes on each side. Fill the rest of the barbecue with the courgette slices – as they are so thin, they'll only need cooking on one side. After 2 minutes, turn over the skewers and cook for a further 2 minutes while you start taking off the courgettes. 4. Pour 3 tablespoons of good olive oil into a large bowl. Squeeze in the lemon juice and add the peas, broad beans and grilled courgettes. Tear over the mint leaves and the chive flowers, if using. Season with a little salt and pepper and gently mix everything together. 5. Serve the vegetables in a big bowl in the middle of the table with the skewers on a wooden board next to it. Perfect light, healthy summer eating. Tips <a href="http://www.jamieoliver.com/recipes/seafood-recipes/bay-salt-prawn-skewers-with-summer-veg/">Jamie says: </a>The combination of bay leaves and prawns is quite an unconventional one, but I think it's a winner. This recipe will make enough for a decent batch of bay salt – you can use it instead of normal salt. You won't need as much as you would normally use though, as the bay gives it extra flavour. Bay salt is great if sprinkled over a shoulder of lamb, a chicken or a piece of pork before roasting. You can keep it in a container for a couple of months if you dry it out first.

5 easy ways to reduce your salt intake

If you think your salt intake isn’t an offensive amount then chances are, you may be wrong. Salt is sneaky, it hides away in food that is processed, in different condiments and your favourite meals that may be deemed as “healthy”. The good news is, it isn’t difficult to reduce our salt intake. Speaking to <a href="https://www.bhg.com.au/reduce-salt-intake?category=health">Better Homes and Gardens</a>, dietitian Joel Feren said, “Salt – aka – sodium is a necessary nutrient. However, too much of it can lead to heart disease and kidney failure. “This is because it causes extra strain on your heart to effectively pump the blood around the body. So, reducing sodium in your diet can ease the pressure on your blood vessels and reduce the load on the heart.” According to the Heart Foundation, 75 per cent of our salt intake comes from processed foods, including sauces. Other culprits are chips, bacon, frozen meals, biscuits and cakes. Here’s 5 easy ways you can reduce your salt intake: 1. Know how to read labels “Knowledge is power. If you know what’s in your food, you can make better and more informed choices about what to eat and what to leave on the supermarket shelf,” says Joel. “When it comes to sodium, choose products with less than 400mg per 100g. Better yet, select foods with less than 120mg of sodium per 100g for a gold medal winner.” 2. Try and eat natural foods “Opting for low-processed foods is gold standard! Much of the sodium we consume is actually derived from processed foods,” says Joel. “Nevertheless, there’s no need to throw the baby out with the bathwater so don’t give up healthy packaged foods like whole grain breakfast cereals and breads, tinned fish or canned lentils, but reduce your intake of chips, processed meats, pretzels etc.” 3. Use this chance to experience new flavours “Experiment with herbs and spices to maximise flavour,” says Joel. “Well-established flavour combinations include tomato and basil, fish and lemon as well as pork and sage. Jazz it up and discover your own culinary partnerships.” 4. Up your fruit and veggie intake It’s clear that Aussies don’t eat enough fruit and vegetables. In fact, only 7 per cent of us meet our vegetable requirement and a little over half of us meet our fruit requirement each day,” says Joel. “Fruit and vegies contain a wide array of different nutrients, including potassium. This vital mineral opposes the actions of sodium so it can help reduce blood pressure and ease the load on our cardiovascular system.” 5. Switch to a healthier salt “Ditch regular table salt for <a href="https://www.nepbio.com/collections/heart-salt">Heart SALT</a>! It has 56 per cent less sodium, making it a suitable alternative. Your heart and kidneys will thank you for making the change,” Joel tells <a href="https://www.bhg.com.au/reduce-salt-intake?category=health">Better Homes and Gardens</a>.

They’re willing to fork out for fancy food and bigger seats, but it seems there’s one item Virgin Australia’s business class passengers can’t resist pinching – the number one stolen item from flights was the business class salt and pepper shakers, designed to look like the sails of the Sydney Opera House. <blockquote class="twitter-tweet"> On Virgin Australia flights in business class they give you salt and pepper shakers in the shape of the Sydney Opera House <a href="https://t.co/T3502nMm90">pic.twitter.com/T3502nMm90</a> — Mildly Interesting (@interest_mild) <a href="https://twitter.com/interest_mild/status/949271394453467137?ref_src=twsrc%5Etfw">January 5, 2018</a></blockquote> <blockquote style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 658px; padding: 0; width: calc(100% - 2px);" class="instagram-media"> <div style="padding: 8px;"> <div style="background: #F8F8F8; line-height: 0; margin-top: 40px; padding: 34.90740740740741% 0; text-align: center; width: 100%;"> <div style="background: url(data:image/png; base64,ivborw0kggoaaaansuheugaaacwaaaascamaaaapwqozaaaabgdbtueaalgpc/xhbqaaaafzukdcak7ohokaaaamuexurczmzpf399fx1+bm5mzy9amaaadisurbvdjlvzxbesmgces5/p8/t9furvcrmu73jwlzosgsiizurcjo/ad+eqjjb4hv8bft+idpqocx1wjosbfhh2xssxeiyn3uli/6mnree07uiwjev8ueowds88ly97kqytlijkktuybbruayvh5wohixmpi5we58ek028czwyuqdlkpg1bkb4nnm+veanfhqn1k4+gpt6ugqcvu2h2ovuif/gwufyy8owepdyzsa3avcqpvovvzzz2vtnn2wu8qzvjddeto90gsy9mvlqtgysy231mxry6i2ggqjrty0l8fxcxfcbbhwrsyyaaaaaelftksuqmcc); display: block; height: 44px; margin: 0 auto -44px; position: relative; top: -22px; width: 44px;"></div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/BIkOttWAft_/" target="_blank">A post shared by tracey and tony (@aspiretraveller)</a> on Aug 1, 2016 at 5:28am PDT </div> </blockquote> They’ve proven so popular, in fact, that Virgin Australia is now considering selling them online. “We do get lots of positive feedback about them and we’re looking at ways to make them available for guests to purchase.” The surprising revelation comes as the airline reveals its brand-new business class menu, designed by acclaimed Aussie chef Luke Mangan, which features dishes made to reflect each flight’s destination, made from Australian ingredients. Among the restaurant-quality meals are a beef wonton soup for Hong Kong-bound passengers, steamed barramundi with sweet potato curry on domestic flights and a delicious lamb moussaka with eggplant, broad beans and peas. Yum! The airline also announced a new selection of wines tested to ensure they taste as good in the air as they do on land. “It was a challenging environment and we found that the wines with abundance of fruit and balanced acidity and tannins won the day,” Hardys winemaker Paul Carpenter told <a href="https://www.escape.com.au/news/virgin-australia-launches-new-business-class-menu-designed-by-luke-mangan/news-story/8cbfbffde8f56cdf7eed402102407f30" target="_blank">Escape</a>. “A fascinating observation of the way wine changes in the sky.”

Travel Tips

Salt doesn’t make you thirsty

Salt actually makes you hungrier not thirstier, according to a new study. German researchers at the Max Delbrück Center for Molecular Medicine (MDC) studied two separate groups of 10 men during a simulation of a trip to Mars at the German Aerospace Center. Over 200 days the "cosmonauts" were given identical diets except for their salt intake. Results of the investigations published in the Journal of Clinical Investigation found that a salty diet actually caused the men on the high salt diets to drink less. The men who ate more salt, retained more water, weren't as thirsty and needed more energy, according to the findings. Scientists have known that increasing a person's salt intake stimulates the production of urine and it has been assumed that the extra fluid comes from drinking more because they were thirsty. But it now appears that salt triggers a mechanism in the kidney that causes the kidneys to hold onto water and produce urea - a process which consumes energy, causing hunger not thirst. "Nature has apparently found a way to conserve water that would otherwise be carried away into the urine by salt," said Freidrich Luft from the MDC. Studies in mice have previously hinted that the production of urea was responsible for this increased appetite, Luft added. Urea is a compound and is the end product of protein metabolism. It is formed in the liver and excreted by the kidneys in the urine. It is generally thought of as a waste product but Luft said that's wrong. "Instead it turns out to be a very important osmolyte, a compound that binds to water and helps transport it," said Prof Luft. "Its function is to keep water in when our bodies get rid of salt."

The reason you need to go to the loo in the middle of the night

Researchers in Japan have found that the cause of needing to wee in the middle of the night is related to the salt in your diet. Nocturia is the name given to the need to urinate during the night and it can strongly impact someone’s life as their sleep is regularly disturbed. Scientists from Japan have discovered that if salt intake is reduced, the need to wee in the night is also reduced. Dr Matsuo Tomohiro from Nagasaki University said, "Research generally focuses on reducing the amount of water a patient drinks, and the salt intake generally is not considered. Here we have a useful study showing how we need to consider all influences to get the best chance of improving the symptom.” The study involved 300 men and women who reduced their salt intake by 10.7 grams to eight grams. This reduction decreased the number of times participants needed to urinate from 2.3 times to 1.4 times. The study was presented at the European Society of Urology congress in London. Dr Tomohiro says that although larger studies need to confirm their work, the findings are promising. "Night-time urination is a real problem for many people, especially as they get older. This work hold out the possibility that a simple dietary modification might significantly improve the quality of life for many people," Dr Tomohiro said.

Country pork, walnut & fennel terrine with salted cucumber

This rustic terrine is perfect picnic fare. Made in advance, it requires minimal effort and looks and tastes spectacular, especially when served with crusty bread, radishes and quick salted cucumber, which adds a lovely fresh, crunchy element to complement the richness of the terrine. All that's needed now is a refreshing beverage – try the zesty passionfruit soda, or, for something a little more grown-up, rose cooler and pink sangria fit the bill perfectly. You'll need to begin this recipe a day before you want to serve it to allow time for the terrine to set. Serves: Eight Ingredients: <ul> <li>200g thinly sliced streaky bacon or pancetta</li> <li>900g free-range pork mince</li> <li>1 egg, lightly beaten</li> <li>1 clove garlic, finely chopped</li> <li>1 tablespoon chopped parsley</li> <li>1 teaspoon chopped sage</li> <li>60g fresh walnut pieces, toasted</li> <li>1 teaspoon fennel seeds, toasted, ground</li> <li>1 large cucumber, halved lengthwise, deseeded, sliced</li> <li>2 tablespoons flaky sea salt</li> <li>2 tablespoons sliced chives</li> <li>1/2 teaspoon mustard powder</li> <li>30ml extra virgin olive oil</li> <li>Juice of 1 lemon</li> <li>Crusty bread, radishes and Dijon mustard to serve</li> </ul> Method: <ol> <li>Preheat the oven to 120°C. Line a terrine mould or loaf tin with a double layer of plastic wrap, leaving enough overhang to fold over the top once filled.</li> <li>Line the mould with the bacon slices, allowing them to hang over the sides so you'll be able to fold them over the mince mix.</li> <li>Put the mince, egg, garlic, parsley, sage, walnuts and fennel in a bowl and season well with salt and freshly ground black pepper. Mix well to combine then press into the mould.</li> <li>Fold the bacon over the top then fold the plastic wrap over the bacon, pressing down firmly.</li> <li>Put the terrine in a roasting dish then add enough hot water to the dish to come halfway up the sides of the tin. Bake for two hours or until the internal temperature of the terrine reaches 65°C or the juices are rose coloured when the terrine is pierced with a skewer.</li> <li>Remove the terrine from the water and allow to cool then top with cans or other weights to compress the terrine and refrigerate overnight.</li> <li>For the salted cucumber, combine the cucumber and salt in a sieve over the sink and set aside for 30 minutes. Use your hands to squeeze out any liquid then transfer to a bowl and stir in the chives, mustard powder, oil and lemon juice to taste.</li> <li>Serve with slices of the terrine, with bread, radishes and mustard on the side.</li> </ol> Mmm, have you ever tried a dish like this?
