Nowadays a vegetarian lifestyle is becoming more and more popular. Leading health experts agree that maintaining a vegetarian diet is one of the best things we can do for ourselves and our families.
66 . A well-planned vegetarian diet provides us with all the nutrients we need and avoids fat, cholesterol（胆固醇） and the pollutants found in animal flesh, eggs, and dairy products. And it can provide protection against various kinds of diseases, including the three biggest killers: heart disease, cancer, and strokes. The American Dietetic Association states that vegetarians have lower rates of death from heart disease, lower blood cholesterol levels, lower blood pressure and lower rates of hypertension(高血压) . 67 .
Scientists have also found that vegetarians have stronger immune systems than their meat-eating friends. 68 . Vegetarians live, on average, 6 to 10 years longer than meat-eaters.
69 . Animals raised for food consume the vast majority of their calories simply in order to live, just as we do. We feed more than 70 percent of the grains and cereals we grow to farm animals, and almost all of those calories go into simply keeping them alive, not making them grow. Only a small amount of the calories consumed by farm animals are actually turned into the meat that people eat . So it’s really a huge waste, isn’t it ?
