听力原文: Nowadays, some vegetarians do not eat any meat products or any food made from animal, including milk products, eggs and honey. This kind of diet is called a vegan diet. But most vegetarians include dairy products in their diet and many vegetarians eat eggs. (26)Some people consider themselves partial vegetarians, because they do not eat meat or farm birds, but they do eat fish.
A study has shown that the human body's structure is actually not suited for animal meat consumption. Moreover, during animal produce, people may use drugs which might have side effect on human health. With a vegetarian diet, you may not have to worry about these possible health risks.
(28) Plant food is a direct source of more nutrients compared to animal food. Especially when vegetarian diets are well planned, you can be sure that you will be getting proper nutrition that you need, which is necessary for good health. Too often, it has become a common misunderstanding that nutrition from meat consumption is better than vegetarian nutrition. Normally, vegetarians have more endurance than those who eat meat. Vegetarians can still get adequate amounts of protein by increasing intake of wheat, whole grains and vegetables without meat. (27) Moreover, the nutrition that a vegetarian diet provides can give you a healthier body and a positive attitude towards life, which can lead to a better quality of life. In fact, vegetarians are known to live longer lives than meat eaters.
