Vitamins & minerals
These are only needed in minute amounts but are required for many processes in the body.
Since the body cannot make vitamins and minerals they must be provided by the diet.
Deficiency of any of these nutrients can result in ill health.
A varied diet, with plenty of fruit and vegetables, will usually provide all the vitamins and minerals the body requires (with a few exceptional circumstances, eg the increased requirement for folic acid during pregnancy).
