Vitamins
Eating a wide variety of fruit and vegetables means you're more likely to get all the vitamins and minerals you need. But what are vitamins - and why are they so important to your good health?
- Vitamins are organic substances - this means
- Most vitamins can't be made by your body,
and the B vitamin niacin are exceptions to this.
- Nutritionists have divided vitamins into two groups:
- The fat-soluble vitamins - A, D, E and K -
They can also be stored in your fat and
liver cells for a limited period of time.
- The water-soluble vitamins - B and C -
They need to be eaten every day, as you can't store them for
any length of time.
