The foods are less calorie dense, have a higher number of vitamins and minerals and generally healthier. The definition of a vegetarian diet is the consumption of vegetable based products and no meat or meat products. However, this does not mean that white flour, sugar or processed foods are completely removed from the diet, all of which are high in dense calories and are related to disease and illness.
