A strict vegetarian is a person who never in his life eats anything derived from animals. The main objection to vegetarianism on a long-term basis is the difficulty to getting enough protein, the body building elements in food. If you have ever been without meat or animal foods for some days of weeds (say, for religious reasons) you will have noticed that you tend to get physically rather weak. You are glad when the fast is over and you get your reward of a succulent meat meal. Proteins are built up from approximately twenty food elements called \animal protein than in vegetable protein. This means you have to eat a great deal more vegetable than animal food in order to get enough of these amino-acids. A great of the vegetable food goes to waste in this process and from the physiological point of view there is not much to be said in favor of life-long vegetarianism.

The economic side of the question, though, must be considered.

Vegetable food is much cheaper than animal food. However, since only a small proportion of tae vegetable protein is useful for body-模考吧www.mokaoba.com

building purposes, a consistent vegetarian, if he is to gain the

necessary 70 grams of protein a day, has to consume a greater bulk of food than his digestive organs can comfortably deal with. In

fairness, though, it must be pointed out that vegetarians claim they need far less than 70 grams of protein a day.

Whether or not vegetarianism should be advocated for adults, it is definitely unsatisfactory for growing children, who need more protein than they can get from vegetable sources. A lacto-vegetarian diet, which includes milk and milk products such as cheese, can, however, be satisfactory as long as enough milk and milk products are consumed.

Meat and cheese are the best sources of usable digestible and next come milk, fish and eggs. Slow and careful cooking of meat makes it more digestible and assists in the breaking down of the protein

content by the body. When cooking vegetables, however, the vitamins, and in particular the water-solube vitamin C, should be lost through overcooking.

A vegetarian is a person who ______. A eats the meat of animals only B eats the vegetable only C drinks milk only D eat nothing at all 【正确答案】：B
