A healthy diet has to do two things:
- Provide enough energy and nutrients to keep up normal body functions
- Allow body tissues to grow and be replaced
It also needs to give you the best protection against the risk of disease, so to be sure you are eating a healthy diet check that it provides the following:
Carbohydrate, fat and protein- These all provide a source of energy and in addition, protein also helps your body to grow and replace body tissues. Having a supply of energy is very important as without energy the human body can die within weeks.
Vitamins, mineral and trace elements- don't supply energy so can't sustain life, but are very important in keeping your body systems working normally and avoiding disease.
Dietary fibre- are undigested plant food remainders which are very important for helping to keep your bowels working properly and increasing 'satiety' (the satisfied feeling after eating that lets you know you've eaten enough).
Finally and by no means least Fluid- lack of fluid (dehydration) can cause constipation, increase your risk of a kidney stone and mental confusion. In extreme conditions, without fluid the human body cannot survive for more than a few days.
Watch out for articles that explain which foods contain carbohydrates, protein, fibre etc.
