According to studies, vegetarians have better health than people that eat meat. They have lower rates of coronary artery disease, gallstones, cancer (particularly lung and colon cancer), kidney stones, colon disease, diabetes and high blood pressure. It has been shown that sometimes a vegetarian diet can help cure these diseases. A vegetarian is also less likely to be overweight than a non-vegetarian. In 1961, the Journal of the American Medical Association stated that ninety to ninety-seven percent of heart disease, the cause of more than half the deaths in the United States, could be prevented by a vegetarian diet. The American Heart Association report states, "In well-documented population studies using standard methods of diet and coronary disease assessment
evidence suggests that a high-saturated-fat diet is an essential factor for a high incidence of coronary heart disease." In 1990, the British Medical Journal Lancet reported on a study by Dr Dean Ornish of the University of California. Dr Ornish found that a vegetarian diet reversed clogging of the arteries in patients with serious heart disease. In 1990, Dr Walter Willet, who conducted a study of diet and colon cancer, said, "If you step back and look at the data, the optimum amount of red meat you eat should be zero." The National Academy of Science reported in 1983 that "people may be able to prevent many common cancers by eating less fatty meats and more vegetables and grain." The USDA recommends that people reduce saturated fat and cholesterol, which are in high amounts in animal products, and low in vegetarian diets. In his Notes on the Causation of Cancer, Rollo Russell writes, "I have found of twenty-five nations eating flesh largely, nineteen had a high cancer rate and only one had a low rate, and that of thirty-five nations eating little or no flesh, none had a high rate." Various studies have shown that vegetarians have lower blood pressure than non-vegetarians. Vegetarians have much lower...
