Journal: The Journal of Nutrition

 Publication Date: 11/2003

 Summary: A review of the micronutrient deficiencies that have been identified in people on a vegetarian diet and the negative health consequences of these deficiencies.

Effect of Creatine and Weight Training on Muscle Creatine and Performance in Vegetarians


Journal: Medicine & Science in Sports & Exercise

 Publication Date: 11/2003

 Summary: Vegetarian and non-vegetarian subjects were enrolled in this study of the effects of creatine supplementation vs placebo on creatine levels, body composition and functional performance. At baseline vegetarians had lower creatine levels. Creatine supplementation resulted in increased creatine levels, improved performance and more lean body mass versus placebo. These increases were greater in vegetarians and those that had lower initial creatine levels.

Signs of impaired cognitive function in adolescents with marginal cobalamin status


Journal: The American Journal of Clinical Nutrition

Publication Date: 09/2000

Summary: Data on dietary intake, psychological test performance, and biochemical variables of cobalamin status were collected from 48 adolescents who consumed macrobiotic (vegan type) diets up to the age of 6 y, subsequently followed by lactovegetarian or omnivorous diets, and from 24 subjects (aged 10–18 y) who were fed omnivorous diets from birth onward. Our data suggest that cobalamin deficiency, in the absence of hematologic signs, may lead to impaired cognitive performance in adolescents.
