L'alimentation végétarienne

Numerous studies have evaluated the health benefits of food that are appropriately selected by vegetarians. Risks of dietary deficiency are limited when diet is correctly planned including fortified foods, particularly in vegan diet. This is the case for vitamin B12, vitamin D, calcium, iron, zinc and omega-3 fatty acids. Vegetarians have an increased consumption of fruits, vegetables, whole-grains, legumes and nuts, together with other contributors such as regular physical activity, absence of overweight, tobacco and alcohol which are almost always present among vegetarians. According to numerous studies, vegetarians have better health than non-vegetarians, lower risk of coronary heart disease explained by low LDL cholesterol, lower blood pressure and lower BMI. Vegetarians have also lower risk of obesity, stroke, type 2 diabetes and certain cancers than do non-vegetarians.
