Vegetarianism is the practice of abstaining from the consumption of meat(red meat,poultry,seafood and the flesh of any other animal), and may also include abstention from by-products of animal slaughter.
Such ethical motivations have been codified under various religious beliefs, along withanimal rights. Other motivations for vegetarianism are health-related, political,environmental, cultural, aesthetic or economic. Some vegans also avoid animal products such as leather (and possibly silk) for clothing and goose-fat for shoe polish.
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. 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, due to fish and birds being animals.
Types of Vegetarianism
The Academy of Nutrition and Dietetics (AND) classifies vegetarians more specifically in the following ways:
1.) Vegans or total vegetariansexclude all animal products (e.g. meat, poultry, fish, eggs, milk, cheese, and other dairy products). Many vegans also do not eat honey.
2.) Lacto-vegetarians exclude meat, poultry, fish, and eggs but include dairy products.
3.) Lacto-ovo vegetarians exclude meat, poultry, and fish but include dairy products and eggs. Most vegetarians in the US are lacto-ovovegetarians.

Compared to omnivores, vegetarian populations have a lower overall mortality rate and in particular benefit from a reduced incidence of many non-communicable diseases including heart disease, type 2 diabetes and cerebrovascular disease. A vegetarian diet reduces cancer risk, except for breast cancer.
A vegetarian diet which is badly planned can lead to hyperhomocysteinemia and platelet disorders; this risk may be offset by ensuring sufficient consumption of vitamin B 12 and polyunsaturated fatty acids.
The Academy of Nutrition and Dietetics and Dietitians of Canada have stated that at all stages of life, a properly planned vegetarian diet is “healthful, nutritionally adequate, and provides health benefits in the prevention and treatment of certain diseases”. Large-scale studies have shown that mortality from ischaemic heart disease was 30% lower among vegetarian men and 20% lower among vegetarian women than in non-vegetarians. Vegetarian diets offer lower levels of saturated fat, cholesterol and animal protein, and higher levels of carbohydrates, fibre, magnesium, potassium, folate, and antioxidants such as vitamins C and E and phytochemicals.
Vegetarian diets can meet guidelines for the treatment of diabetes and some research suggests that diets that are more plant-based reduce risk of type-2 diabetes. Rates of self-reported Seventh-day Adventists (SDA) were less than half of those of the general population, and, among SDA, vegetarians had lower rates of diabetes than non-vegetarians. Among possible explanations for a protective effect of vegetarian diet are the Lower BMI of vegetarians and higher fiber intake, both of which improve insulin sensitivity.”
The relationship between vegetarian diet and bone health remains unclear. According to some studies, a vegetarian lifestyle can be associated with vitamin B 12 deficiency and low bone mineral density. However, a study of vegetarian and non-vegetarian adults in Taiwan found no significant difference in bone mineral density between the two groups. Other studies, exploring animal protein’s negative effects on bone health, suggest that vegetarians may be less prone to osteoporosis than omnivores, as vegetarian subjects had greater bone mineral density and more bone formation.
Enriching your Vegetarian Diet
Protein:
Protein is found in both plant foods and animal foods. Vegetarians should be aware that while there are plenty of plant-based protein options, many of these foods contain less protein per serving compared to animal foods. Therefore, combining one or more protein sources at a meal is helpful. Adequate intake with a wide variety of foods from all food groups should fulfill your protein needs. Good sources of protein include lentils, beans, tofu, soybeans (edamame), soy products (veggie burgers etc), textured vegetable protein (TVP), low-fat dairy products, nuts, seeds, tempeh, and eggs.
Calcium:
The AND recommends that adults 19 to 50-years-old consume at least 1000mg of calcium per day — the equivalent of 3 cups of milk or yogurt. Vegetarians can meet their calcium needs if they consume adequate amounts of low-fat and fat-free dairy products such as milk, yogurt, and cheese. Calcium is also found in many plant foods including dark, leafy greens (e.g. spinach, kale, mustard, collard and turnip greens, and bok choy), broccoli, beans, dried figs, and sunflower seeds, as well as in calcium-fortified cereals, cereal bars and some fortified juices.
Vegans (people who don’t eat any animal products) must strive to meet their daily calcium requirements by regularly including these plant sources of calcium in their diets. Many soy milk products are fortified with calcium, but be sure to check the label for this. Although almond milk may also be calcium-fortified, it is lower in protein so soy milk may be a better alternative to dairy.
Calcium is best absorbed by the body when it comes from food, so it’s best to include calcium-rich foods in your diet on a regular basis. If these foods are not part of your typical diet, then you may consider a calcium supplement. Look for one that has 500 mg calcium or more per serving AND contains vitamin D. It’s important to take this supplement with a meal, rather than on an empty stomach. Calcium supplements are available at thepharmacy.
Vitamin D:
Vitamin D helps your body absorb and use calcium. There are few foods that are naturally high in vitamin D, though. Therefore, dairy products in the US are fortified with vitamin D. Many soy milk products are also fortified with vitamin D. Your body can make its own vitamin D, but only when the skin is exposed to adequate sunlight (but that can have its own risks). A person only needs about 10 minutes of sunlight exposure for an adequate dose of vitamin D; then it’s important to apply sunscreen. People who do not consume dairy products and who do not receive direct exposure to sunlight regularly should consider taking supplemental vitamin D. The recommended intake of Vitamin D for college students is 600 international units (IU) per day.
Iron:
Iron-fortified breads and cereals, dark green vegetables (e.g. spinach and broccoli), dried fruits, prune juice, blackstrap molasses, pumpkin seeds, sesame seeds, and soybean nuts are good plant sources of iron. Consuming foods high in vitamin C, such as citrus fruits or juices, tomatoes, and green peppers helps your body absorb iron from these plant sources. Cooking food in iron pots and pans will also add to your iron intake.
Vitamin B-12:
Vitamin B-12 is produced in animals and by bacteria in the soil. Vegetarians who consume dairy products and/or eggs usually get enough B-12 since it is found in these foods. Vegans, however, should add vitamin B-12 fortified soy milk to their diets. Regularly taking a broad-spectrum multivitamin and mineral supplement (available at the pharmacy) will also supply the necessary amount of B-12. Vitamin B12 can also be obtained from fortified yeast extract products.
Zinc:
Zinc is an essential component of many enzymes and plays a role in cell division and in formation of proteins. Like iron, zinc is not as easily absorbed from plant sources as it is from animal products. Cheese is a good option if you eat dairy products. Plant sources of zinc include whole grains, soy products, legumes, nuts and wheat germ.
