Which of the following is NOT true about Resveratrol？ ______
A．Resveratrol is a healthy substance found in the skin of red grapes.
B．Resveratrol is higher in concentration in white wine than red wine.
C．Grape pulp extract (white wine) was equally effective in protecting rats from a heart attack as grape skin extract (red wine).

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.

Bust a myth, get a benefit
Few subjects harbor more myths and misconceptions than nutrition. Some of the most common:
"Low-fat" means "healthy".
Low-fat foods can be healthy, but not always. The problem？ Many processed foods that are low in fat are high in sugar, which gives you extra calories and may cause wide swings in your blood sugar levels. This makes you gain weight and lose energy, and may raise your risk of several diseases. Some people believe "low-fat" means "Eat all you want. "
I remember a dieting patient who was puzzled because he was gaining weight. He mentioned he was eating a low-fat cake. When I asked him bow much, he replied, "Oh, one or two. " "One or two pieces？ No, one or two cakes!"
An ideal diet is low in fat and low in sugar. Most people can enjoy high-sugar, high-fat treats on occasion, but if you indulge one day, be sure to eat healthier the next.
Canned fruits and vegetables aren't nutritious.
They can be. A recent review of studies found that nutrients are generally similar in comparable fresh, frozen and canned fruits and vegetables. Many parents have told me that, knowing this, they might be more likely to cook at home rather than eat less nutritious meals at restaurants.
Red wine, not white, prevents heart disease.
Yes, drinking red wine may significantly decrease the risk of heart disease, but white wine may be just as protective, at least in rats.
Resveratrol is a healthy substance found in the skin of red grapes. It's higher in concentration in red wine than white because red wine is fermented with the skins, allowing it to absorb the resveratrol. American and Italian researchers recently found that grape pulp extract (white wine) was equally effective in protecting rats from a heart attack as grape skin extract (red wine). Also, most of the antioxidant benefits of wine come from the grape itself, not the fact that it's fermented.
Studies show that spending time with friends and family may reduce the risk of many illnesses. People who imbibe moderately often do so in the company of others, and these psychosocial factors may be as powerful as the drink itself. I neither prescribe nor proscribe alcohol, but if you're going to drink, have no more than one or two four-ounce glasses of wine, one or two beers, or one or two ounces of liquor. More than that and the toxicities of alcohol begin to outweigh any of its potential benefits.
Juice is less healthy than whole fruits.
Not always. "The view that pure fruit and vegetable juices are nutritionally inferior to fruits and vegetables, in relation to chronic-disease risk reduction, is unjustified," concluded a recent review of studies. The impact of antioxidants on disease risk may be more important than the amount of fiber. Whole fruits and vegetables do have more fiber than most juices, and fiber has many benefits. It fills you up before you get too many calories, and it helps regulate blood sugar. Some juice companies are preserving the pulp (which adds to the fiber) or are even putting it back in.
Summer Diet Traps.
It's the season for travel, day trips and meals on the run, and it's easier than ever to eat healthy on the road. At airports, look for fresh fruit and packaged salads. Dip your fork in the dressing instead of pouring it on. Amusement parks are providing healthier choices. Disney will eliminate added trans fats from its parks by the end of this year, and kids'meals will include sides like applesauce and carrots—not fries. Some fast-food places offer better choices, too, so you can eat well just about anywhere.
According to the passage, which of the following is true？ ______
A．Nutrition bears the most misconceptions.
B．Low-fat is always healthy.
C．Canned fruits and vegetables are absolutely not nutritious.
D．During summer people should eat less or not at all.
