Vitamins and minerals are essential nutrients your body needs in small amounts to work properly.

There are two types of vitamins: fat-soluble and water-soluble.
Fat-soluble vitamins are found mainly in fatty foods and animal products, such as vegetable oils, milk and dairy foods, eggs, liver, oily fish and butter.
While your body needs these vitamins every day to work properly, you don't need to eat foods containing them every day.
This is because your body stores these vitamins in your liver and fatty tissues for future use. These stores can build up so they are there when you need them. However, if you have much more than you need, fat-soluble vitamins can be harmful.
Fat-soluble vitamins are:
Water-soluble vitamins are not stored in the body, so you need to have them more frequently.
If you have more than you need, your body gets rid of the extra vitamins when you urinate. As the body does not store water-soluble vitamins, these vitamins are generally not harmful. However, this doesn't mean that all large amounts are necessarily harmless.
Water-soluble vitamins are found in a wide range of foods, including fruit, vegetables, potatoes, grains, milk and dairy foods. Unlike fat-soluble vitamins, they can be destroyed by heat or being exposed to the air. They can also be lost in water used for cooking.
This means that by cooking foods, especially boiling them, we lose some of these vitamins. The best way to keep as many of the water-soluble vitamins as possible is to steam or grill foods, rather than boil them, or to use the cooking water in soups or stews rather than pouring it away.
There are also many other types of vitamins and minerals that are an important part of a healthy diet.
Minerals are necessary for three main reasons:
Minerals are found in foods such as meat, cereals (including cereal products such as bread), fish, milk and dairy foods, vegetables, fruit (especially dried fruit) and nuts.
Trace elements are also essential nutrients that your body needs to work properly, but in much smaller amounts than vitamins and minerals.
Trace elements are found in small amounts in a variety of foods such as meat, fish, cereals, milk and dairy foods, vegetables and nuts.
