Red Meat Links to Higher Risk of Breast Cancer

Exercise and keeping a healthy weight are two things that doctors say might help women lower their risk of breast cancer.

Mothers may reduce their risk if they breastfeed for at least four months. For older women, hormone replacement therapy can lower the risk of some other diseases. But it has been found to increase the risk of breast cancer. So women should consider their choices carefully. The same may be said for diet.

New findings show that younger women who eat a lot of red meat have higher rates of breast cancers called hormone-receptor positive. The growth is fed by the levels of estrogen or another hormone, progesterone, in the body.

Researchers at Brigham Women's Hospital in Boston, Massachusetts, reported the findings as part of a health study of nurses. The researchers followed the health of more than 90,000 women from 1991 to 2003. Those who ate the most red meat ate more than one and one-half servings a day. A serving was defined as roughly 84 grams. Those who ate the least red meat ate less than three servings a week. This is what the study found about breast cancers that were hormone receptor-positive: The women who ate the most red meat were almost two times as likely to get them as the women who ate the least of it.

Eunyoung Cho, the lead author of the report, says more research is needed to know the reason for the link. But in the past, researchers have suggested that three things may play a part. One is the way meat is cooked or processed. Another is the use of growth hormones in cows. And the third is the kind of iron in red meat. The study appears in the Archives of Internal Medicine.

And now we have more to tell you about our subject -- resveratrol. We discussed a study in the United States that found that large amounts of this plant compound helped fat mice live longer. The mice were fed much more resveratrol than people could get from red wine, one of the foods that contains it.

Now, scientists in France say resveratrol also improves muscle performance -- again, at least in mice. They were able to run two times as far in laboratory treadmill tests4 as mice normally could. The study at the Institute of Genetics and Molecular and Cellular Biologys appeared in the journal Cell.

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 "amino-acids", 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 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-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

Vegetarian

A strict vegetarian is a person who never in his life eats anything derived from(来自于)animals.The main objection to vegetarianism on a long-term basis is the difficulty of getting enough protein(蛋白质), the body-building elements in food.If you have ever been without meat or animal foods for some days or weeks, say, for religious reasons, you will have noticed that you tend to get physically weak.You are glad when the fast(斋戒)is over and you get your reward of a great meat meal.

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 e-nough of these amino-acids. A great deal 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 the vegetable protein is useful for body-building purposes, a consistent (坚定的) 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 unsatis- factory for growing children, who need more protein than they can get from vegetable sources.

There is a lacto-vegetarian(乳酸素食者)diet which includes milk and milk products .Meat and cheese are the best sources of usable digestible protein 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-soluble(水融性) vitamin C, should not be lost through over-cooking.
