Vegetarian diets are gaining popularity. A vegetarian diet includes plant products, seeds, nuts and excludes animals and all forms of products obtained from animals. Since, vegetarians do not include animal meat and dairy items in their diet, they sometimes miss out on essential vitamins, like vitamin B12 and vitamin D, which are chiefly found in meat and dairy products. Due to this, vegetarians are at a high risk of having vitamin deficiency and therefore, may need to take vitamin supplements. Vegetarian diets are usually low in fats and cholesterol and are considered healthy. Dietitians Canada and American Dietetic Association both have certified that, well planned vegetarian diets are healthy and nutritious.
