People need to manage the quantity, type and proportion of foods that they eat as part of a healthy lifestyle or, for sportspeople, as part of a training and performance regime.
Diet is the variety of foods that are eaten over a period of time. As no single food provides all of the body's required nutrients, an individual's diet should be balanced across a variety of foods. Individual foods are not necessarily healthy or unhealthy. Healthy eating requires a balanced diet.
Eatwell plate
A balanced diet includes different foods from each of the five main food groups. The NHS eatwell plate shows these food groups and the proportions in which they should be eaten. The foods in the smallest group – high in fat and/or sugar – are not required as part of a healthy diet.
