If there was a single act that would improve your health, cut your risk of food-borne illnesses, and help preserve the environment and the welfare of millions of animals, would you do it?
   The act I’m referring to is the choice you make every time you sit down to a meal.
   More than a million Canadians have already acted: they have chosen not to eat meat. And the pace of change has been dramatic.
   Vegetarian food sales are showing unparalleled growth. Especially popular are meat-free burgers and hot dogs, and the plant-based cuisines of India, China, Mexico, Italy and Japan.
   Fuelling the shift toward vegetarianism have been the health recommendations of medical research. Study after study has uncovered the same basic truth: plant foods lower your risk of chronic disease; animal foods increase it.
   The American Dietetic Association says: "Scientific data suggest possible relationships between a vegetarian diet and reduced risk for several chronic degenerative diseases."
   Animal foods have serious nutritional drawbacks: They are devoid of fiber, contain far too much saturated (饱和的) fat, and may even carry traces of hormones, steroids (类固醇) and antibiotics. It makes little difference whether you eat beef, pork, chicken or fish.
   Animal foods are also gaining notoriety as breeding grounds for E. coli (大肠杆菌), campylobacter (弯曲菌) and other bacteria that cause illness.
   So why aren’t governments doing anything about this? Unfortunately, they have bowed to pressure from powerful lobby groups such as the Beef Information Center, the Canadian Egg Marketing Agency and the Dairy Farmers of Canada. According to documents retrieved through the Freedom of Information Act, these groups forced changes to Canada’s latest food guide before it was released in 1993.
   This should come as no surprise: Even a minor reduction in recommended intakes of animal protein could cost these industries billions of dollars a year.
   While health and food safety are compelling reasons for choosing a vegetarian lifestyle, there are also larger issues to consider.  Animal-based agriculture is one of the most environmentally destructive industries on the face of the Earth.
