Image Caption : Both the American Heart Association and the U.S. Department of Agriculture (USDA) recommend daily portions of fruits and vegetables, which are high in fiber, vitamins, and minerals, and low in salt, saturated fats, and cholesterol. Green, leafy vegetables such as spinach and broccoli are high in folic acid and vitamin B, which control the levels of an amino acid - homocysteine - in the blood. Homocysteine can cause nicks in the arterial wall and promote the development of atherosclerosis.
A vegetarian diet focuses on plants for food. These include fruits, vegetables, dried beans and peas, grains, seeds and nuts. There is no single type of vegetarian diet. Instead, vegetarian eating patterns usually fall into the following groups:
- The vegan diet, which excludes all meat and animal products
- The lacto vegetarian diet, which includes plant foods plus dairy products
- The lacto-ovo vegetarian diet, which includes both dairy products and eggs
People who follow vegetarian diets can get all the nutrients they need. However, they must be careful to eat a wide variety of foods to meet their nutritional needs. Nutrients vegetarians may need to focus on include protein, iron, calcium, zinc and vitamin B12.

Vegetarianism /ˈvɛdʒətɛəriənɪzəm/ is the practice of abstaining from the consumption of meat (red meat, poultry, seafood, insects and the flesh of any other animal), and may also include abstention from by-products of animal slaughter.
Vegetarianism can be adopted for different reasons. Many object to eating meat out of respect for sentient life. Such ethical motivations have been codified under various religious beliefs, along with animal rights. Other motivations for vegetarianism are health-related, political, environmental, cultural, aesthetic, economic, or personal preference. There are varieties of the diet as well: an ovo-vegetarian diet includes eggs but not dairy products, a lacto-vegetarian diet includes dairy products but not eggs, and an ovo-lacto vegetarian diet includes both eggs and dairy products. A vegan diet excludes all animal products, including eggs, dairy, and honey. Some vegans also avoid other animal products such as beeswax, leather or silk clothing, and goose-fat shoe polish.
Various packaged or processed foods, including cake, cookies, candies, chocolate, yogurt and marshmallows, often contain unfamiliar animal ingredients, and may be a special concern for vegetarians due to the likelihood of such additions. Often, products are reviewed by vegetarians for animal-derived ingredients prior to purchase or consumption. Vegetarians vary in their feelings regarding these ingredients, however. For example, while some vegetarians may be unaware of animal-derived rennet's role in the usual production of cheese and may therefore unknowingly consume the product, other vegetarians may not take issue with its consumption.
Semi-vegetarian diets consist largely of vegetarian foods, but may include fish or poultry, or sometimes other meats, on an infrequent basis. Those with diets containing fish or poultry may define meat only as mammalian flesh and may identify with vegetarianism. A pescetarian diet has been described as "fish but no other meat". The common use association between such diets and vegetarianism has led vegetarian groups such as the Vegetarian Society to state that diets containing these ingredients are not vegetarian, because fish and birds are also animals.
