The consumption of animal products has been conclusively linked to heart disease, cancer, diabetes, arthritis, and osteoporosis. Cholesterol (found only in animal products) and animal fat clog arteries, leading to heart attacks and strokes. The rate of many cancers—including colon, breast, cervical, uterine, ovarian, prostate, and lung—is highest in regions where meat consumption is high and lowest where meat-eating is uncommon.
A study of more than 25,000 people found that vegetarians have a much lower risk of getting diabetes than meat-eaters. A South African study found not a single case of rheumatoid arthritis in a community of 800 people who ate no meat or dairy products. There is no physical reason for humans to eat animal products. Cutting animal products from your diet is healthier for you, the animals, and the environment.
