Ingrid KAN, a dietitian, suggests children, elderly and pregnant vegetarians to consume more plant proteins and iron. Mothers-to-be have to absorb more iron and calcium to meet the nutritional requirements of themselves and their fetuses, or the new born babies will be at risk of iron deficiency and slow growth. Elderly persons should eat an appropriate amount of ground nuts and seeds to obtain the necessary nutrients, according to Ingrid.

A food pyramid, Ingrid concludes, suggests that people should eat more grains, cereals and vegetables, and an appropriate amount of fish, meat, eggs, beans and dairy food. If we can follow the pyramid, a vegetarian diet is just as good.
