Vegetarian diets.

A growing number of Americans are choosing to follow vegetarian diets. These diets can meet the nutritional needs of individuals of all ages. Vegetarians who eat eggs and/or milk and dairy products have no special problems in obtaining adequate nutrients. Pure vegetarians, who avoid all animal products, should pay particular attention to sources of protein, calcium, and riboflavin. Supplementation of vitamin B12 is indicated in these individuals. Guidelines for both good normal nutrition and therapeutic diets can be adapted for use with a vegetarian diet.
