Fruit and vegetables which have not been liquidised are universally considered to be healthy foods. It is important to get a wide variety of them and to include pulses for increased roughage, too. Meat can be eaten as part of a healthy eating regime, but it should be consumed only once in a while and not at every meal. Fish and shellfish, especially oily fishes, are also a big part of healthy diets as are cereals so long as they, too, are eaten in moderation. Basically, healthy eating means a varied diet which avoids too many processed foodstuffs.
