FAQs (Frequently Asked Questions)
Answers to some of our most commonly asked salt questions
Q: How much salt do we need per day?
A: We need less than 1 gram per day. The current government recommendation is to eat a maximum of 6 grams a day; this is about a teaspoon of salt.
Q: Isn’t salt good for you? We need it, why do I need to eat less?
A: We need about 1g of salt per day, about a pinch, for our bodies to function, but we’re eating about 7-10g per day. Too much salt puts up our blood pressure, leading to heart disease and stroke, and is linked to numerous other diseases.
Q: Should children have a lower salt diet too?
A: Yes. Our taste preferences are formed in childhood, and high blood pressure tracks from childhood to adulthood, so it’s important not to give children high salt foods. A high salt intake, due to foods such as gravy and salty sauces, is dangerous to babies and very young children. Read more about salt and children.
Q: Which foods are the highest in salt?
A: The highest salt foods are processed foods like baked beans, soups, processed meat such as ham and bacon, smoked foods, ready meals, restaurant and takeaway food, some cereals and even bread. It is difficult to avoid eating some of these foods but look for low salt alternatives instead, or eat fresh food which has no added salt.

Q: When shopping, how do I know which foods are high, low or medium in salt?
A: Low = Less than 0.30g salt per 100g of food
Medium = 0.30g – 1.50g salt per 100g of food
High = over 1.50g salt per 100g of food
Q: What is the difference between sodium and salt?
A: Sodium is a part of salt, salt is comprised of sodium and chloride.
Q: How do I work out how much salt is in a product if only sodium is labelled?
A: Most labels tell us how much salt is present. If sodium is given, multiply the number by 2.5 to get the figure for salt.
Q: If the recommendation is no more than 6g per day, why do labels have Guideline daily amounts of 5g for women, and 7g for men?
A: Men and women require different amounts of energy and nutrients, such as fat and salt, per day and sometimes labels take account of this. As a rule of thumb, it is simpler to remember that the maximum daily recommendation for teenagers and adults is 6g per day.
Q: Are rock and sea salt more healthy than table salt?
A: No. Rock, sea and table salt are all made of approximately 100% sodium chloride so are all equally damaging to our health.
Q: I like the taste of salt, what alternatives can I use in my cooking?
A:Alternative flavours you could use include herbs, spices -like some curry powders, mustard powder, lemon or lime juice, vinegar, red or white wine, cider or beer, onions, garlic, shallots, ginger, chillies...
If you really can't get used to not having salt with some foods, then try a salt substitute such as LoSalt which contains potassium in place of some of the sodium.
Q: If I eat less salt, wont food taste bland?
A: Only for a short time - stick with it! Within 3-4 weeks your taste buds will adjust and become more sensitive so you will get the same amount of flavour from less salt and will even prefer the taste of food with less salt. You’ll also be able to taste the natural flavours of food.
Q: I do a lot of exercise, should I eat more salt?
A: Unless you’re a top level athlete, no. You only lose a small amount of salt in sweat, and as we all eat more than we need, most people won’t need to take on any extra. Remember to keep hydrated.
