There's little doubt anymore that vegetarianism is going mainstream. Millions of people are vegetarians, and thousands more make the switch to a meat-free diet every week. Many others have greatly reduced the amount of animal products they eat.
Many people eliminate animal foods from their diet because of health concerns. In study after study, the consumption of animal foods has been linked with heart disease, stroke, cancer, diabetes, arthritis and other illnesses. One reason may be because animals are routinely given growth hormones, antibiotics, and even pesticides, which remain in their flesh and are passed on to meat-eaters.
Other people become vegetarians out of concern for animal welfare. On today's factory farms, animals often spend their entire lives confined to cages or stalls barely larger than their own bodies. Death for these animals doesn't always come quickly or painlessly. Billions of animals are killed for food in the United States alone.
Reducing health risks and eliminating animal suffering are just two reasons to go vegetarian; adopting a plant-based diet can also help protect the environment and feed the hungry. Factory farms produce billions of tons of animal waste. The waste produced in a single year would fill 6.7 million train box cars, enough to circle the Earth 12 1/2 times. Unfortunately much of this waste ends up in our rivers and streams, polluting waterways more than all industrial sources combined.
Raising animals for food is also taking its toll on the world's forests. Since 1960, more than one-quarter of the rain forests in Central America have been destroyed to create cattle pastures. Of the Amazonian rain forest cleared in South America, more than 38 percent has been used for ranching. Rain forests are vital to the survival of the planet because they are the Earth's primary source of oxygen. And scientists are increasingly exploring the use of rain-forest plants in medications to treat and cure human diseases.
Veganism takes vegetarianism beyond the diet. A vegan (pronounced Vee-g'n) is someone who tries to live without exploiting animals, for the benefit of animals, people and the planet. A vegan does not eat any animal food products, avoids wearing animal-derived products and does not purchase toiletries, cosmetics and cleaning products that have been tested on animals or contain animal based ingredients. They also refrain form supporting animal entertainment and other industries that exploit animals. Instead, vegans choose from thousands of animal-free foods, products and entertainment.
Veganism is a philosophy, not a diet. This philosophy is the belief in the right of all sentient beings to be treated with respect, not as property, and to be allowed to live their lives.
A balanced vegan diet (also referred to as a ‘plant-based diet’) meets many current healthy eating recommendations such as eating more fruit, vegetables and whole grains and consuming less cholesterol and saturated fat. Balanced vegan diets are often rich in vitamins, antioxidants and fiber and can decrease the chances of suffering from diseases such as diabetes, heart disease, stroke and some cancers. Well-planned plant-based diets are suitable for all age groups and stages of life.
Many people become vegan through concern of the way farmed animals are treated. Some object to the unnecessary ‘use’ and killing of animals – unnecessary as we do not need animal products in order to feed or clothe ourselves. Public awareness of the conditions of factory-farmed animals is gradually increasing and it is becoming more and more difficult to claim not to have at least some knowledge of the treatment they endure. Sentient, intelligent animals are often kept in cramped and filthy conditions where they cannot move around or perform their natural behaviors. At the same time, many suffer serious health problems and even death because they are selectively bred to grow or produce milk or eggs at a far greater rate than their bodies are capable of coping with.
Regardless of how they were raised, all animals farmed for food meet the same fate at the slaughterhouse. This includes the millions of calves and male chicks who are killed every year as ‘waste products’ of milk and egg production and the animals farmed for their milk and eggs who are killed at a fraction of their natural lifespan. Choosing a vegan diet is a daily demonstration of compassion for all these creatures.
Vegans also help the planet. Plant-based diets only require around one third of the land and water needed to produce a typical Western diet. Farmed animals consume much more protein, water and calories than they produce, so far greater quantities of crops and water are needed to produce animal ‘products’ to feed humans than are needed to feed people direct on a plant-based diet. With water and land becoming scarcer globally, world hunger increasing and the planet’s population rising, it is much more sustainable to eat plant foods direct than use up precious resources feeding farmed animals. Farming animals and growing their feed also contributes to other environmental problems such as deforestation, water pollution and land degradation.
Choosing to live a life free from animal products means choosing a path that is kinder to people, animals and the environment.
VEGANS & PROTEIN
Can the vegan (strict vegetarian) diet provide protein adequate for sound human health? This question continues to be asked despite the fact that a "yes" answer was given some three decades ago in a study reported by Hardinge and Stare. The question stays with us largely because animal products (meat, milk, cheese, and eggs) have been promoted (usually by the industries that produce and sell them) as the best source of protein. This dietary assumption is wrong and can even be harmful, as a quick study of the facts about vegetable protein and nutrition shows.
Protein is essential to human health. In fact, our bodies -- hair, muscles, fingernails, and so on -- are made up mostly of protein. As suggested by the differences between our muscles and our fingernails, not all proteins are alike. This is because differing combinations of any number of 22 known amino acids may constitute a protein. (In much the same way that the 26 letters of our alphabet serve to form different words, the 22 amino acids serve to form different proteins.)
Amino acids are a fundamental part of our diet. While most of the 22 can be manufactured in one way or another by the human body, eight (or, for some people, 10) cannot. These "essential amino acids" can easily be provided by a balanced vegan diet.
Non-animal foods can easily provide us with the necessary protein. Despite the claims of the meat and dairy industries, only 2.5-10 percent of the total calories consumed by the average human being needs to be in the form of protein. The rule of thumb used by the National Academy of Sciences Food and Nutrition Board is .57 grams of protein for every kilogram (2.2 pounds) of body weight. People under special circumstances (such as pregnant women) are advised to get a little more. Vegans should not worry about getting enough protein; if you eat a reasonably varied diet and ingest sufficient calories, you will undoubtedly get enough protein.
Eating too much protein can result in osteoporosis and kidney stones. Meat and dairy products raise the acid level in human blood, causing calcium to be excreted from the bones to restore the body's natural pH balance. This calcium depletion results in osteoporosis, or weakening of the bones. The excreted calcium ends up in the kidneys, where it often forms painful stones. Kidney disease is far more common in meat-eaters than in vegans, and excessive protein consumption has also been linked to cancer of the colon, breast, prostate, and pancreas. By replacing animal protein with vegetable protein, you can improve your health while enjoying a wide variety of delicious foods.
While just about every vegetarian food contains some protein, the soybean deserves special mention, for it contains all eight essential amino acids and surpasses all other food plants in the amount of protein it can deliver to the human system. In this regard it is nearly equal to meat. The human body uses about 70 percent of the protein found in meat and 60 to 65 percent of that found in soybeans. The many different and delicious soy products (tempeh, soy "hot dogs," "burgers," Tofutti brand "ice cream," and tofu) available in health and grocery stores suggest that the soybean, in its many forms, can accommodate a wide range of tastes.
Other rich sources of non-animal protein include legumes, nuts, seeds, food yeasts and freshwater algae. Although food yeasts ("nutritional yeast" and "brewer's yeast") do not lend themselves to forming the center of one's diet, they are extremely nutritious additions to most menus (in soups, gravies, breads, casseroles, and dips). Most yeasts are 50 percent protein (while most meats are only 25 percent). Freshwater algae contains a phenomenal percentage of protein. One type is the deep green spirulina, a food that is 70 percent protein. It is available in tablets, powders, and even candy bars.
Protein deficiency need not be a concern for vegans. If we ate nothing but wheat, oatmeal, or potatoes, we would easily have more than enough protein. Eating nothing but cabbage would provide more than twice as much protein as anyone would need! Of course, an actual vegan would never want to be limited to just one food. The vegan diet can (and should) be full of a wide variety of delicious foods.
Most people have been taught that children must eat animal flesh and dairy products to grow up strong and healthy. The truth is that children raised as vegans, who consume no animal products, including meat, eggs, and dairy, can derive all the nutrients essential for optimum growth from plant-based sources.
Consider this: Many children raised on the "traditional" American diet of cholesterol and saturated fat-laden hamburgers, hot dogs, and pizza are already showing symptoms of heart disease -- the number one killer of adults -- by the time they reach first grade. One epidemiological study found significant levels of cholesterol and fat in the arteries of most children under the age of five. Children raised as vegans can be protected from this condition. They are less likely to suffer from childhood illnesses such as asthma, iron-deficiency anemia and diabetes, and will be less prone to ear infections and colic.
A vegan diet has other benefits, too. According to the Centers for Disease Control, there are more than 20,000 E. coli infections from meat every year in the United States. A vegan diet protects children from the pesticides, hormones and antibiotics that are fed to animals in huge amounts and concentrate in animals' fatty tissue and milk.
Nutritionists and physicians have learned that plant products are good sources of protein, iron, calcium, and vitamin D because they can be easily absorbed by the body and don't contain artery-clogging fat.
Protein--Contrary to popular opinion, the real concern about protein is that we will feed our children too much, not too little. Excess animal protein actually promotes the growth of tumors--and most people on a meat-based diet consume three to 10 times more protein than their bodies need! Children can get all the protein their bodies need from whole grains in the form of oats, brown rice, and pasta; from nuts and seeds, including spreads such as tahini and peanut butter; and legumes, including tofu, lentils, and beans.
Iron--Few parents know that some babies' intestines bleed after drinking cow's milk. This increases their risk of developing iron-deficiency anemia since the blood they're losing contains iron. Breast-fed infants under the age of one year get sufficient iron from mother's milk (and are less prone to Sudden Infant Death Syndrome). Formula-fed babies should be fed a soy-based formula with added iron to minimize the risk of intestinal bleeding. Iron-rich foods such as raisins, almonds, dried apricots, blackstrap molasses and fortified grain cereals will meet the needs of toddlers and children 12 months and older. Vitamin C helps the body absorb iron, so foods rich in both, such as green, leafy vegetables are particularly valuable.
Calcium--Drinking cow's milk is one of the least effective ways to strengthen bones. Too much protein, such as the animal protein fed to children in dairy products, actually causes the body to lose calcium. In countries where calcium intake is low but where protein intake is also very low, osteoporosis is almost non-existent. Cornbread, broccoli, kale, tofu, dried figs, tahini, great northern beans and fortified orange juice and soy milk are all excellent sources of calcium. As with iron, vitamin C will help your child's system absorb calcium efficiently.
Vitamin D--This is not really a "vitamin" but a hormone our bodies manufacture when our skin is exposed to sunlight. Cow's milk does not naturally contain vitamin D; it's added later. Vitamin D-enriched soy milk provides this nutrient without the added animal fat. A child who spends as little as 15 minutes a day playing in the sunshine, with arms and face exposed, will get sufficient vitamin D.
Vitamin B-12--This essential vitamin once occurred naturally on the surfaces of potatoes, beets, and other root vegetables, but the move away from natural fertilizers has caused it to disappear from our soil. Any commercially available multivitamin will assure adequate B-12 for your child. B-12 is also found in nutritional yeast (not to be confused with brewer's or active dry yeast) and many fortified cereals.
Dangers of Dairy Products
Children do not need dairy products to grow up strong and healthy. The director of pediatrics at Johns Hopkins University, Dr. Frank Oski, says, "There's no reason to drink cow's milk at any time. It was designed for calves, it was not designed for humans, and we should all stop drinking it today, this afternoon." Dr. Benjamin Spock agrees that although milk is the ideal food for baby cows, it can be dangerous for human infants: "I want to pass the word to parents that cow's milk . . . has definite faults for some babies. It causes allergies, indigestion, and contributes to some cases of childhood diabetes."
The American Academy of Pediatrics recommends that infants under one year of age not be fed whole cow's milk. Dairy products are the leading cause of food allergies. In addition, more than two-thirds of Native Americans and people from Asian and Mexican ancestry and as many as 15 percent of Caucasians are lactose intolerant and suffer symptoms such as bloating, gas, cramps, vomiting, headaches, rashes or asthma. Many people become lactose intolerant after age four. For these people, animal proteins seep into the immune system and can result in chronic runny noses, sore throats, hoarseness, bronchitis and recurring ear infections.
Milk is suspected of triggering juvenile diabetes, a disease that causes blindness and other serious effects. Some children's bodies see cow's milk protein as a foreign substance and produce high levels of antibodies to fend off this "invader." These antibodies also destroy the cells which produce insulin in the pancreas, leading to diabetes.
An estimated 20 percent of U.S. dairy cows are infected with leukemia viruses that are resistant to killing by pasteurization. These viruses have been found in supermarket supplies of milk and dairy products. It may not be merely coincidence that the highest rates of leukemia are found in children ages 3-13, who consume the most dairy products.
