Passage 2
A strict vegetarian is a person who never in his life eats anything from animals. The main objection to vegetarianism(食素主义) is the difficulty of getting enough protein — the body-building element in food. If you have ever been without meat or other animal foods for some days of weeks you will have noticed that you tend to get physically rather weak.
Proteins are built up from approximately twenty food elements called “amino-acids”(氨基酸), which are found more abundantly in 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 deal of the vegetable food goes to waste in this process and 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 amount of the vegetable protein is useful for body-building purpoeses, 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 (消化器官) 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.
