Why Not Eat Breakfast？

Breakfast is not only the most important meal of the day, it is also the most neglected or skipped. Common reasons for not eating breakfast include lack of time, not feeling hungry, traditional dislike for breakfast, and dieting.

Breakfast simply means "break the fast." Your body spends at least six to twelve hours each night in a fasting state. In the morning your body needs energy to rev up （转动起来） into high gear for the day's work ahead.

If you skip breakfast， you are likely to concentrate less effectively in the late morning， feel irritable， short-tempered（易怒的）， tired， or weak.

When you choose not to eat breakfast, your body stays in slow gear. Also, people

who skip breakfast often binge （无节制的大吃） later in the day at other meals or eat a high-calorie （高卡路里） snack in the morning. Breakfast eaters tend to eat less fat during the day， have more strength and endurance and better concentration and problem-solving ability.

A good breakfast should provide up to 1/3 of your total calorie needs for the day. On the average, we eat 400 less calories for breakfast than for dinner. If breakfast doesn't appeal to you in the morning, try eating a lighter-dinner, earlier in the evening or save half your dinner for breakfast in the morning.

If you still aren't hungry in the morning, start with something small like juice or toast or have a mid-morning snack later when you are hungry.

Not eating breakfast can also cause you to overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slowed state, it will not be able to burn those extra calories very efficiently. If you feed your body healthy snacks and meals throughout the day, you are less likely to become extremely hungry and stuff yourself as soon as you begin to eat.

Since breakfast is the first and most important meal of the day, choosing the right fuel is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as breads, rice, noodles, and cereals.

36 The word fast" in the phrase "break the fast" in paragraph 2 means

A．"a series of quick actions".

B．"a habit of eating".

C．"a period of not eating".

D．"a strict rule".

Eat to Live

A meager diet may give you health and long life, but it&39;s not much fun -- and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don&39;t start to diet until old age.

Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse&39;s liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won&39;t reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.

Spindlers team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old equivalent to about 70 human years.

The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production-- probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of these gene changes.

"This is the first indication that these effects kick in pretty quickly." say Huber Warner from the National Institute on Aging near Washington D. C.

No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There&39;s attracting and tempting evidence out there that it will work," he says.

If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient, at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective.

But Spindler isn&39;t sure the trade-off is worth it. "The mice get. less disease, they live longer,but they&39;re hungry," he says, "Even seeing what a diet does, it&39;s still hard to go to a restaurant and say: &39;I can only eat half of that&39;." Spindler hopes we soon won&39;t need to diet at all. His company,Lifespan Genetics in California, is looking for drugs that have the effects of caloric restriction.

According to.the passage， which of the following is NOT true？查看材料

A.Eating less than usual might make us live longer

B.We go on a diet when old， we may keep healthy

C.Dieting might not be needed

第二篇

Not content with its doubtful claim to produce cheap food for our own population, the factory farming industry also argues that "hungry nations are benefiting from advances made by the poultry(家禽) industry". In fact, rather than helping the fight against malnutrition(营养不良) in "hungry nations", the spread of factory farming has, inevitably aggravated the problem.

Large-scale intensive meat and poultry production is a waste of food resources. This is because more protein has to be fed to animals in the form. of vegetable matte than can ever be recovered in the form. of meat. Much of the food value is lost in the animal' s process of digestion and cell replacement. Neither, in the case of chicken, can one eat feathers, blood, feet or head. In all, only about 44% of the live animal fits to be eaten as meat.

This means one has to feed approximately 9～10 times as much food value to the animal than one can consume from the carcass. As a system for feeding the hungry, the effects can prove disastrous. At times of crisis, grain is the food of life.

Nevertheless, the huge increase in poultry production throughout Asia and Africa continues. Normally British or US firms are involved. For instance, an American based multinational company has this year announced its involvement in projects in several African countries. Britain's largest suppliers of chickens, Ross Breeder, are also involved in projects all over the world.

Because such trade is good for exports, Western governments encourage it. In 1979, a firm in Bangladesh called Phoenix Poultry received a grant to set up a unit of 6,000 chickens and 18,000 laying hens. This almost doubled the number of poultry kept in the country all at once.

But Bangladesh lacks capital, energy and food and has large numbers of unemployed. Such chicken-raising demands capital for building and machinery, extensive use of energy resources for automation, and involves feeding chickens with potential famine- relief protein food. At present, one of Bangladesh' s main imports is food grains, because the country is unable to grow enough food to feed its population. On what then can they possibly feed the chicken？

In this passage the author argues that______。

A. efficiency must be raised in the poultry industry

B. raising poultry can provide more protein than growing grain

C. factory farming will do more harm than good to developing countries

D. hungry nations may benefit from the development of the poultry industry
