Today, more and more dietitians are seeing vegetarian clients. Estimates of the number of vegetarians in the United States range from less than 1% to 4% of the population (1-4). The vast majority of vegetarians in this country eat dairy products and eggs; from 2% to 20% of U.S. vegetarians are vegans (4-6). A vegan (also called strict, pure, or total vegetarian) avoids all animal products.
Vegetarians seek nutrition counseling for a variety of reasons. These include a desire to improve an existing vegetarian diet, advice on the transition to a vegetarian diet, and modification of diet to prevent or treat an existing condition such as renal disease or diabetes. Non-vegetarians will seek help in including more plant-based foods. This review will focus on adult, non-pregnant vegetarians. Several publications provide sound advice for pregnant women (7-10) and infants and children (9-11) following vegetarian diets.
