WEDNESDAY, April 1 (HealthDay News) -- Despite its proven health benefits, a vegetarian diet might in fact be masking an underlying eating disorder, new research suggests.

The study, in the April issue of the Journal of the American Dietetic Association, found that twice as many teens and nearly double the number of young adults who had been vegetarians reported having used unhealthy means to control their weight, compared with those who had never been vegetarians. Those means included using diet pills, laxatives and diuretics and inducing vomiting to control weight.

There's a dark side to vegetarianism, said Dr. David L. Katz, director of the Prevention Research Center at Yale University School of Medicine. He had no role in the research.

"Adolescent vegetarians [in the study] were more prone to disordered eating and outright eating disorders," Katz said. "This is not due to vegetarianism but the other way around: Adolescents struggling to control their diets and weight might opt for vegetarianism among other, less-healthful efforts."

Vegetarianism, or a mostly plant-based diet, can be recommended to all adolescents, Katz said. "But when adolescents opt for vegetarianism on their own, it is important to find out why because it may signal a cry for help, rather than the pursuit of health," he said.

Katz said he thinks a balanced vegetarian diet is among the most healthful of dietary patterns, and the study suggests some of the benefits.

"Adolescents practicing vegetarianism were less likely to be overweight than their omnivorous counterparts and, were the measures available, would likely have had better blood pressure and cholesterol, too," he said. "Eating mostly plants -- and even only plants -- is good for us, and certainly far better for health than the typical American diet."
