6. Nutrition Concerns and Health Effects of
Vegetarian Diets
Volume 109, Issue 7, Pages 1266-1282 July 2009

It is the position of the American Dietetic Association that appropriately
planned vegetarian diets, including total vegetarian or vegan diets,
are healthful, nutritionally adequate, and may provide health
benefits in the prevention and treatment of certain diseases. Well-
planned vegetarian diets are appropriate for individuals during all
stages of the life cycle, including pregnancy, lactation, infancy,
childhood, and adolescence, and for athletes. A vegetarian diet is defined as one that
does not include meat (including fowl) or seafood, or products containing those foods. This article reviews the current data
related to key nutrients for vegetarians including protein, n-3 fatty acids, iron, zinc, iodine, calcium, and vitamins D and B-
12. A vegetarian diet can meet current recommendations for all of these nutrients. In some cases, supplements or fortified
foods can provide useful amounts of important nutrients. An evidence-based review showed that vegetarian diets can be
nutritionally adequate in pregnancy and result in positive maternal and infant health outcomes. The results of an evidence-
based review showed that a vegetarian diet is associated with a lower risk of death from ischemic heart disease.
Vegetarians also appear to have lower low-density lipoprotein cholesterol levels, lower blood pressure, and lower rates of
hypertension and type 2 diabetes than nonvegetarians. Furthermore, vegetarians tend to have a lower body mass index
and lower overall cancer rates. Features of a vegetarian diet that may reduce risk of chronic disease include lower intakes
of saturated fat and cholesterol and higher intakes of fruits, vegetables, whole grains, nuts, soy products, fiber, and
phytochemicals. The variability of dietary practices among vegetarians makes individual assessment of dietary adequacy
essential. In addition to assessing dietary adequacy, food and nutrition professionals can also play key roles in educating
vegetarians about sources of specific nutrients, food purchase and preparation, and dietary modifications to meet their
needs.
