题目内容

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.
An example of the dangers of a restricted diet may be seen in the disease known as "beri-beri", which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted by a germ (病菌) . He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain, it was thought this would be easier for weak and sick people to digest.
Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients' plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.
Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice (糙米) somehow prevented or cured beri-beri--even that a lack of some ingredient (成分) in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.

How to eat healthfully can be especially complex for working women who often have neither the desire nor the time to cook for themselves (or for anyone else). Registered dietitian(营养专家)Barhara Morrissey suggests that a few simple rules can help.

“Go for nutrient dense foods，” she suggests, “foods that contain a multiple of nutrients. For example, select whole wheat bread as a breakfast food, rather than coffee cake. Or drink orange juice rather than orange drink, which contains only a small percentage of real juice —the rest is largely coloured sugar water. You just can't compare the value of these foods, the nutrient dense ones are so superior，” she emphasizes.

Morrissey believes that variety is not only the spice of life—it's the foundation of a healthful diet. Diets which are based on one or two foods are not only virtually impossible to keep up the strength, they can be very harmful, she says, because nutrients aren't supplied in sufficient amounts or balance.

According to Morrissey, trying to find a diet that can cure your illnesses, or making you superwoman is a_fruitless_search. As women, many of us are too concerned with staying thin, she says, and we believe that vitamins are some kind of magic cure to replace food.

“We need carbohydrates, protein and fat — they are like the wood in the fireplace. The vitamins and minerals are like the match, the spark, for the fuel，” she explains. “We need them all, but in a very different proportions. And if the fuel isn't there, the spark is useless.”

8．In Paragraph 4, “a fruitless search” means “________”．

A. an effort with no results

A. a balanced diet can result in being fat

B. staying thin and healthy are both possible

C. lack of variety in diets leads to staying thin
