Vegetarianism is considered a healthy, viable diet. The American Dietetic Association and the Dietitians of Canada have found a properly planned vegetarian diet to satisfy the nutritional needs for all stages of life, and large-scale studies have shown that vegetarians's "mortality for major causes of death was not significantly different between vegetarians and nonvegetarians, but the nonsignificant reduction in mortality from ischemic heart disease among vegetarians"[22][23][24] Necessary nutrients, proteins, and amino acids for the body's sustenance can be found in vegetables, grains, nuts, soymilk, eggs and dairy.[25]

Vegetarian diets can aid in keeping body weight under control[26][27] and substantially reduce risks of heart disease and osteoporosis.[28][28][29][29] Non-lean red meat, in particular, has been found to be directly associated with dramatically increased risk of cancers of the lung, oesophagus, liver, and colon.[30][31] Other studies have shown that there were no significant differences between vegetarians and nonvegetarians in mortality from cerebrovascular disease, stomach cancer, colorectal cancer,breast cancer, or prostate cancer, although the sample of vegetarians was small and included ex-smokers who had switched their diet within the last five years.[32]

The American Dietetic Association and Dietitians of Canada have stated: "Vegetarian diets offer a number of nutritional benefits, including lower levels of saturated fat, cholesterol, and animal protein as well as higher levels of carbohydrates, fibre, magnesium, potassium, folate, and antioxidants such as vitamins C and E and phytochemicals."[24] Vegetarians tend to have lower body mass index, lower levels of cholesterol, lower blood pressure, and less incidence of heart disease, hypertension, type 2 diabetes, renal disease, osteoporosis, dementias such as Alzheimer’s Disease and other disorders.[33]
