Forming the mid-section of the pyramid are the foods that should be consumed moderately with the small apex at the top indicative of the foods that one should eat of less frequently. .
Foods from the "eat most" section of the Healthy Eating Pyramid consist of breads, cereals, fruits, vegetables, dried peas, beans and lentils. It is recommended to eat most of these foods as not only are they generally low in fat but they provide an excellent source of dietary fibre, vitamins and minerals and do not contain a lot of sugar. Cereals usually enrich the diet with complex carbohydrates, dietary fibre and minerals. Nutritionists recommend wholegrain over refined cereals because of the additional complex carbohydrates, dietary fibre and B group vitamins.

Dried peas, beans and lentils also contain some carbohydrates and supply the body with plenty of protein, fibre and minerals. Fibre content aids in lowering the blood cholesterol.
