An extreme form of vegetarianism that progresses through 10 stages of dietary restriction with the gradual elimination of animal products, fruits, and vegetables. The initial stages may meet minimum nutritional requirements. However, the highest stages allow only cereals (mainly brown rice) in the diet and are nutritionally inadequate. The diet of the last three stages is poor in proteins, calcium, and vitamins B12 and C. Deficiencies of these nutrients may cause growth retardation in children and can be fatal in adults. See also macrobiotic diet.
