The New Vegetarianism More Canadians consider themselves vegetarians than ever before - between 4% and 10% of Canadians are vegetarian or vegan. It’s impossible to say exactly how many there are since the term has a loose definition. Just a very small percentage of vegetarians follow a strict regimen of only plant products. Most eat some animal products – usually dairy products, eggs, or even fish or chicken – at least occasionally. And there’s been another change: most turn to vegetarianism today for its health benefits rather than for ethical or environmental reasons. Here are some questions and answers to help you weigh the advantages and disadvantages of the vegetarian way of eating. What are the different types of vegetarians? Strict vegetarians, sometimes called vegans, avoid all foods of animal origin. Far more common are: Lacto-vegetarians: these include dairy products in their diets, mainly as protein sources. Ovo-vegetarians: those who also eat eggs. Lacto-ovo-vegetarians: those who eat dairy products and eggs, but no animal flesh. Pesco-vegetarians: those who eat fish, dairy products, and eggs. Semi-vegetarians: those who eat dairy products and eggs, as well as fish and chicken, but no read meat. Vegan: those who consume no meat, fowl, fish or animal products, including eggs, dairy or animal by-products. Doesn’t eating meat undo the beneficial effects of a vegetarian diet? Not if you eat only small amounts of meat and it is lean. In fact, when the Surgeon General and groups such as the American Heart Association recommend eating less meat and more fruits, vegetables, and grains, they are basically calling for a semi-vegetarian diet. Such “heart-healthy” meal plans suggest eating meat as a side dish or condiment (3-5 oz of meat per meal), rather than as a main course, and call for increased consumption of grains and beans as protein sources. Many ethnic cuisines, such as those in Mexico, Mediterranean countries, and the Far East, also build dishes around starches and vegetables. What are the health benefits? The clearest is a reduced risk of coronary artery disease. This can be attributed to vegetarians’ lower average blood cholesterol levels and lower blood pressure than meat eaters. There is some evidence that switching to a very low-fat-vegetarian diet may even help reverse the effects of atherosclerosis once they have occurred. There is also some evidence that vegetarians have a lower risk of various cancers – notably of the colon and lungs – than the average North American. And in countries where people are primarily vegetarian, breast cancer rates tend to be low. It’s true, of course, that some of the benefits attributed to what vegetarians eat may mount up to how they live. Many abstain from tobacco and drugs and limit their alcohol intake. They tend to exercise more and are less likely to become overweight. All these factors contribute to a lower risk of chronic diseases. Of course, a vegetarian diet by itself won’t cancel the effects of smoking and other bad health habits. Isn’t it hard for a vegetarian to get a balanced diet and avoid vitamin or mineral deficiencies? IT depends on how restricted a vegetarian’s diet is. If you still eat dairy products, for example, or even a little chicken or fish, there’s little to worry about. However, strict vegetarians need to plan their diets with some care. When they do, they are no more prone to deficiencies than meat eaters. The potential deficiencies in strict vegetarian diets are: Vitamins B2, B12, and D. B2 is found primarily in meat, eggs, and dairy products, though broccoli, asparagus, almonds, and fortified cereals are also good sources. B12 and D are found only in animal products. A lack of B12 can bring on anemia as well as degenerative changes in the central nervous system. If you’re not eating meat, dairy products or eggs, you’ll have to get your B12 from fortified products such as soy milk or from a supplement. Vitamin D is necessary for calcium absorption and a deficiency can cause rickets in children. You need very little of this vitamin and given adequate exposure to the sun, the body is able to synthesize it. Calcium, iron, and zinc are the major mineral concerns. Women, in particular, need to make sure they are consuming enough calcium, which can be a problem if they are vegans, since dairy products are by far the major sources. Broccoli, kale, collard and mustard greens, and fortified tofu also contain calcium, though substances (such as oxalic acid) in some vegetables may reduce the body’s absorption of the calcium. Iron and zinc found in plant foods are not as well absorbed as those in meat and dairy products. Peas, lentils, and wheat germ are good sources of zinc. Vegetarians should definitely continue to make sure they are consuming enough iron, since a low intake can cause anemia and can impair mental function in children. Beans, potatoes, dried fruit, and fortified cereals and breads supply iron. Vegetarian diets are typically high in Vitamin C, which enhances the body’s absorption of iron. Don’t vegetarians have to worry about protein? Vegetarian diets generally supply more than enough protein. Actually, most Americans eat about twice as much protein as is generally recommended. Excessive protein may actually be a problem – for instance, because it increases the loss of calcium in urine, excess protein may increase the risk of osteoporosis. Many grains, legumes, and seeds are surprisingly good sources of protein. But the protein in any single plant food is considered incomplete – that is, it has insufficient amounts of one or more of the nine essential amino acids. Amino acids are the protein’s building blocks, the essential one are those the body can’t synthesize. Virtually all animal products supply a sufficient amount of all essential amino acids and thus provide complete proteins. Is it safe to put children on a vegetarian diet? According to the American Dietetic Association and many other experts, an appropriately planned vegetarian diet is okay for kids. But others disagree, pointing out that vitamin and mineral deficiencies can be particularly harmful for children. It’s a good idea to have a qualified nutritionist evaluate the diet of any infant or child on a strict vegetarian diet. Other vegetarians who should seek professional advice are: pregnant or breast-feeding women, the elderly, people with certain chronic diseases (such as AIDS), or those recovering from an illness. Bottom line It takes only a little planning to keep a vegetarian diet healthful and nutritionally adequate. If you decide to follow a strict vegetarian regimen, the word to remember is variety. Eat a wide range of foods: fruits, vegetables, whole-grain breads and cereals, legumes (such as soybeans, chickpeas, lima beans and lentils), nuts, seeds, and fortified soy products. Dairy products made from low-fat or skim milk, and an egg now and then, makes it easier to get the full range of nutrients. And remember, small servings of lean meat, poultry, or fish will not go against the benefits of a vegetarian diet. Vegetarian cuisine isn’t just for vegetarians. Here’s a guide that will help you find your way through your neighbourhood health food store or falafel stand. SOYBEANS: Bulging with protein, iron, potassium, and other nutrients, these tiny round beans form the basis of most vegetarian diets. They don’t taste like much on their own, but cook them right, and they can taste like just about anything, including meat, milk, and cheese. SOYMILK: For vegans, who won’t drink cow’s milk, or for people who have milk allergies, soy milk is a fine substitute. Made from soybeans, blended with water, it actually tastes pretty good, like a slightly creamier version of cow’s milk. Unlike cow’s milk, however, it is not a good source of calcium. TOFU: Looks like blocks of slightly slippery white cheese. It is another soy product that is low in fat and calories, it can be doctored to taste like meat, cheese, pudding, and ice cream. TEMPEH: A popular meat substitute, tempeh is made from fermented soybeans that are molded into small patties or cakes and then cooked like hamburgers. Tempeh can also be friend in strips, or used in soups or stews. MISO: For most Japanese, a soup made from miso, a paste made from soybeans, is a morning staple. Miso is a protein rich soup, sandwich spread, or seasoning. FALAFEL: This delicious concoction comes from the Middle East, where people eat it throughout the day. Chickpeas, yellow peas, and whole wheat flour are mashed together to form balls or patties and fried in oil. They are crunchy on the outside and soft on the inside.
