Balanced Nutrition
Nutrients connected to Balanced Nutrition
A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.
- Vitamin B2Established role
MedlinePlus advises getting vitamins from a balanced diet with a variety of foods; the NHS says most people can meet their needs this way.
- Vitamin B12Established role
B12 comes from meat, fish, milk, cheese and eggs, or fortified foods. People who eat no animal foods may need supplements.
- Vitamin CEstablished role
The body cannot store vitamin C, so it needs regular food sources; the NHS says a varied diet should supply all you need.
- MagnesiumEstablished role
Magnesium comes from food such as leafy greens, nuts, seeds, beans and whole grains, so a varied diet is the main source.
- IronEstablished role
Iron comes from food. Animal iron is absorbed more easily than plant iron, vitamin C foods help absorption and black tea reduces it. Most people can meet needs from a varied diet.
- SeleniumEstablished role
Selenium comes from food such as Brazil nuts, fish, meat and eggs. The NHS says people who eat meat, fish or nuts should get enough from diet; plant content depends on the soil.
- Vitamin AEstablished role
A varied diet usually gives enough vitamin A. Eating liver more than once a week can push intake too high.
- Vitamin EEstablished role
The NHS says you should be able to get all the vitamin E you need from a varied diet, and MedlinePlus says vitamin E from food is not risky.
- Vitamin B3 (niacin)Deficiency link
A well-balanced diet prevents pellagra; niacin is found in meat, fish, eggs, milk, cereals, legumes and peanuts.
- Vitamin B5Established role
Almost all vegetables, wholegrain foods and meats contain pantothenic acid, so a varied diet usually provides enough. Food processing can cause significant losses.
- Vitamin B6Established role
Most people can get enough B6 from a varied diet (pork, poultry, fish, peanuts, bananas, oats, fortified cereals); gut bacteria also make some.
- Vitamin B9 (folate and folic acid)Established role
Folate comes from foods such as green leafy vegetables, beans, peas, citrus fruit and fortified cereals, so a varied diet supports intake.
- CalciumEstablished role
The NHS says most people can get enough calcium from a varied, balanced diet.
- PotassiumEstablished role
The NHS says a varied, balanced diet should supply all the potassium most people need.
- ZincEstablished role
Zinc comes from foods such as meat, shellfish, dairy, nuts, whole grains and legumes; a varied diet is the usual source.
- IodineEstablished role
Most people can get enough iodine from a varied, balanced diet including dairy, eggs, fish and iodized salt. Strict vegans may need fortified foods or advice.
- ChromiumEstablished role
The NHS says a varied, balanced diet should provide all the chromium you need; meat, nuts and whole grains are sources.
- LysineEstablished role
Lysine must come from food, and it is richest in animal foods, soy, beans and legumes. A varied protein intake over the day matters more than any single supplement.
- TryptophanEstablished role
Tryptophan cannot be made by the body, so it must come from protein foods.
- Omega-3 fatty acids (ALA, EPA and DHA)Preliminary or mixed
Eating seafood supplies EPA and DHA. For some conditions the evidence favours seafood over supplements, partly because of other nutrients or what it replaces.
- Omega-9 fatty acids (oleic acid)Established role
