Nowadays a vegetarian (素食的) lifestyle is becoming more and more popular. Keeping a vegetarian diet is one of the best things we can do.
1 A well planned vegetarian diet provides us with all the nutrients (营养素) we need and avoids fat, cholesterol (胆固醇) found in animal flesh, eggs, and dairy foods. And it can provide protection against various kinds of diseases, including the three biggest killers: heart disease, cancer, and other serious diseases. 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 high blood pressure. 2 Scientists have also found that vegetarians have stronger immune systems than their meat-eating friends. 3 Vegetarians live, on average, 6 to 10 years longer than meat eaters.
4 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 to farm animals. So it’s really a huge waste, isn’t it? Try your best to find tips on the health benefits of a vegetarian diet. 5
