资源简介

First and foremost, eating healthily does not mean that your diet should consist of nothing but salads and steamed vegetables? Although both can be extremely enjoyable! A balanced diet is one made up of a bit of everything in the correct proportions. This ensures your body gets enough of what it needs and is in no way deficient. In fact, recommendations on diet are now laid out not just to prevent deficiency, but to actively promote optimal health!

Nutritional requirements vary depending on a person's age, sex and overall level of fitness and with this in mind, the Department Of Health have set guidelines accordingly. Most of us recognise the term RDA (recommended daily allowance). These have been revised and are now set as DRV's (dietary reference values), that are tailored to certain population groups. However, between the ages of 19 and 50 your requirements do not vary a great deal.

For the average adult, it is recommended that around half of our energy should be provided by carbohydrates, 35% from fats and 15% from protein. For most, putting this into practise will mean making sure that you eat a variety of different foods, with emphasis on foods rich in starch & fibre and smaller proportions of fats & sugars. Also, actively trying to eat more fruit & vegetables is always a good idea as they contain many of the wide range of vitamins and minerals the body needs. 

It is important to remember that all foods can be included, nothing is forbidden as long as it is eaten in the right proportions!
