    Vegetarianism (素食主义) seems more popular than ever. About 8 million Americans consider themselves vegetarians, and an increasing number of them are young people — often the children of vegetarianism or kids who’ve decided to become one in their own. But some question appears whether vegetarianism is a healthy diet for a growing child.
    There are many reasons why people choose a vegetarian lifestyle, including health concerns and love for animals. Whatever the reason, their numbers are surprisingly high, especially for girls.
    The American Dietetic Association estimates that a huge 11 percent of girls, ages 13 to 17, have given up meat and meat products.
    Children and teenagers declare themselves vegetarian to assert dietary independence from their parents. Vegetarian cosmetics and cruelty-free clothes fill corner drugstores and high-end shops. But although vegetarian is trendy, sometimes rebellious and decidedly modern, it’s actually one of the earliest diets. Some cultures have survived without meat for thousands of years. Socrates, Plato, Leonardo da Vinci, Charles Darwin and Thomas Edison were all vegetarians.
The Vegetarian Diet
    The vegetarian diet is straightforward enough: Vegetarians do not eat meat. Some people who avoid beef and pork but still eat poultry or fish mistakenly consider themselves vegetarians. Although vegetarianism has varying degrees, the diet’s core principle is abstention from all meat. Most vegetarians are lacto-ovo-vegetarians — they do not eat meat but they allow dairy products and eggs. Lacto-vegetarians allow dairy, and ovo-vegetarians allow eggs. Vegans take basic vegetarianism several steps further. Instead of abstaining only from eating fish and meat, vegans avoid eating, wearing or using any animal products. This means no eggs or dairy, no honey, no leather, fur, wool or silk, and no cosmetics or chemicals tested on animals.
    There is, however, plenty for vegetarians to eat. Lacto-ovo vegetarians eat fruit, vegetables, grains, nuts, seeds, dairy and eggs. They eat meat substitutes like soybean-based tofu and tempeh, and seitan, a wheat protein. As far as vegans are concerned, the Vegan Society recommends healthy servings of vegetables, fruits, grains, oils and fortified nondairy product like soy milk. Some vegans also eat tempeh, tofu or seitan. Vegans also take supplements of vitamin B12, vitamin D and calcium to make up for any dietary deficiencies.
    Ethnic cooking’s growing popularity has also opened up a world of new vegetarian foods to vegetarians and meat-eaters alike. Middle Eastern, North African, Indian and Asian foods are often vegetarian or easily can be made so.
Reasons for Vegetarianism
    Even with vegetarianism’s various degrees of strictness, the core diet is simply abstention from meat. But that one decision — the decision not to eat meat — can have a lot behind it. Vegetarians choose their diet for many reasons. Some are health-conscious,, some believe animal agriculture hurts the environment and others have moral or religious objections to meat.
    Vegetarianism has become a popular health diet. Vegetarian favorites, like fruit, vegetables, and whole grains, are low in fat and cholesterol (胆固醇) and rich in fiber, vitamins C and E. The American Dietetic Association even reports that vegetarians have lower blood pressure, cholesterol and body mass indexes than non-vegetarians. Of course, no diet is automatically healthy. Vegetarians must make sure they take in enough protein, calcium and vitamin B12 without overindulging in fatty, high-calorie foods like cheese.
    Many vegetarians are as concerned with the Earth’s well-being as they are with their own. Some vegetarians choose the diet for environmental reasons because they believe traditional agriculture has less of an ecological impact than animal agriculture.
    People usually try not to think about where their meat comes from. It can be unpleasant to imagine your hamburger as a wide-eyed cow in the pasture, let alone as an unhealthy animal in a cramped factory farm. But for many vegetarians, disassociation or denial is impossible. They often feel morally unable to eat animals slaughtered for their meat. Vegans take their ethical objections a step further and refuse to eat dairy or eggs from animals that they believe have led unnaturally short and unhappy lives.
    Some of vegetarianism’s ethical concerns have spread to the mainstream. Even steadfast meat-eaters often like the idea of free-range chicken or cage-free eggs — animal husbandry techniques that promise a more compassionate alternative to traditional factory farming.
    Vegetarians have long chosen the diet for ethical reasons. Although the first practitioners only temporarily avoided meat for purification, the first regular vegetarians began the diet after philosophical awakenings in the Eastern Mediterranean region and India.
    The philosopher Pythagoras of Samos (530 BC) taught vegetarianism to his followers. Pythagoras believed that because we are related to animals, we should treat them with kindness. Many other famous philosophers agreed — Plato, Epicurus and Plutarch condemned animal sacrifice and avoided eating meat.
    In India, the Buddhist religion teaches that humans should not kill living creatures for food. Although Buddhism later declined in India, vegetarianism remained and spread among people. Many upper classes and some lower classes adopted the virtue of harmlessness, which forbade hurting living things.
    But how did vegetarianism transform into a health movement in the 19th century and an animal rights issue in the 20th?
The Modern Vegetarian Movement
    Today vegetarianism is trendy — 25 percent of adolescents even think it’s "cool". The success of vegetarian cosmetics and vegetarian foods like veggie dogs and tofurkey is a testament to the diet’s popularity. Groups that promote vegetarianism and animal rights, like the Humane Society of the United States (HSUS) and People for the Ethical Treatment of Animals (PETA), have tremendous lobbying power with major companies. But vegetarianism hasn’t always been so generally accepted, nor has it always been linked with the animal-rights movement.
    In 17th-and 18th-century Europe, some Protestant groups embraced vegetarianism as a moral directive — a way to be sinless. By the 19th century, European and North American vegetarianism had become a fringe health movement. Adherents promoted the dietary benefits of vegetarianism — even coupling it with temperance and anti-tobacco movements. Modern organized vegetarianism began with the formation of the Vegetarian Society in 1847 by the Bible Christian Sect of England. Within a year, the Society had 478 members.
    It wasn’t until the mid-20th century that vegetarianism partnered with animal rights movement. America’s most notorious animal rights organization, PETA, vigorously protests against all animal products and animal testing. It is best known for its bold ad campaigns. The HSUS takes a less strict approach. It accepts that people will eat meat and focus instead on reducing meat consumption, replacing animal products and improving farming techniques. Both PETA and the HSUS, however, are powerful political machines: They hold stock in companies like Tyson, Wal-Mart, McDonald’s and Smithfield’s. The modern vegetarian movement is getting ever more powerful.
