A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart. Studies have shown heart benefits from increased blood flow. These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症).
Better blood pressure
If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently
found that people with high blood pressure who ate 3.5 ounces of dark chocolate
per day for two weeks their blood pressure drop quickly.
Muscle magic
Chocolate milk may help you recover after a hard workout(锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.
Better for your skin. German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women’s skin was moister(滑润的)and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance.
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain.

There are several causes leading to poor eyesight like not enough food, genes (基因) and aging (老化). Televisions, computers and reading are also the causes of having poor eyesight. If you happen to work in front of the computer, it is best to take a break every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight form UV rays.
Eating healthy foods will do good to your eyesight. Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises regularly (定期地) and eats the right kind of food, his eyes will stay in good condition for a long time.
All above are natural ways of eye care that help us keep healthy eyes. Being happy all the time can be helpful to a person"s eyesight, too. In a word, eye care is very important, no matter how old a person is.

New research has found out the surprisingly high levels of salt in many of black people’s favorite meals. I stopped putting extra salt in my food at the table long ago and I try to cut down on the salt I use in cooking. The recommended daily level of salt for adults is 6 grams. It is easy to see that if you avoid processed(加工过的) foods and use salt in your cooking within the limit, you won’t exceed the daily level.
The research showed how much salt there is in some foods that we buy from restaurants and takeaways. An average salad with rice and peas has 6.2 grams of salt. This is more salt than you are supposed to eat for the whole day.
A researcher talked about the importance of home cooking rather than take-outs. At home, he pointed out, not only can you hold control of the salt shaker, but also you can create tasty food which is low on salt. The researcher later provided curry goat and rice and peas. They were low on salt, but completely delicious.
I do not suppose Jamaicans are going to stop buying takeaways soon. But if you suffer from high blood pressure, it is probably better not to buy them often.
小题1:The underlined word “they” in Paragraph 1 refers to ______.
| A．white people | B．black people |
| C．untreated diseases | D．high blood pressure and diabetes |
| A．Black people take in too much salt. |
| B．Black people’s meals are very special. |
| C．Processed foods have too much salt in them. |
| D．6 grams of salt per day is enough for an adult. |
| A．Order no salad in a restaurant. | B．Take in no salt for several days. |
| C．Stop cooking their favorite meals. | D．Eat less takeaways. |
| A．thank those who came to his home for his research |
| B．let people know that eating less salt makes one healthier |
| C．show that tasty food with less salt can be made at home |
| D．prove the less salt the food has the more delicious it is |
| A．Watch the salt. | B．Take care, black people. |
| C．Say no to takeaways. | D．Say no to high blood pressure. |
It doesn"t have to be that way. Health experts say you can still enjoy the holidays.
"It"s OK to indulge（沉溺）, but it doesn"t mean you have to gain weight," said Karen Ansel, a New York-based registered dietitian and a spokeswoman for the American Dietetic Association (ADA). Jessica Crandall, a registered dietitian from Denver who"s also an ADA spokeswoman, added that gaining weight during the holidays and then working hard to lose it again is not good for a person"s body.
For starters, people interested in maintaining their weight during the holidays should keep eating on a regular schedule, the two dietitians said. Research has shown that people who skip meals -- particularly breakfast -- end up eating more throughout the day. "Try and stick to consistent meal times so you can avoid being overly hungry," Crandall said. "When you"re overly hungry, you can make some bad decisions regarding what you eat. Don"t starve yourself during the day waiting for that party at night -- because you"ll eat too much or overeat."
Ansel suggests that you think now about the foods you really enjoy and plan to focus on those while eating less of more common fare.
Be careful, too, about alcohol intake, for a couple of reasons. Alcoholic drinks, particularly the fancy ones handed out at holiday time, tend to come loaded with calories. "It"s usually what you"re adding to a drink that contains the calories," Crandall said. Also, if you"re drunk, you might forget to watch what you"re eating. "It totally lowers your inhibitions（压抑）," Ansel said.
Other holiday eating tips, suggested by Crandall and Ansel, include:
•Eat lots of vegetables, and eat them first before moving on to the other items on your plate.
•Recognize that many holiday extras, like cheese or cranberry sauce, come loaded with calories. "If those aren"t your favorite foods, don"t put them on your plate," Crandall said.
•If your favorite food has a lot of calories, be sure to minimize your portion. "Two bites cure the craving," Crandall said. "After that, you"re just really feeding your old habits.
•After a big holiday meal, don"t sink into a chair or couch. Go for a walk outdoors or participate in some other activities that help burn off some of the calories you"ve just eaten.
小题1:Both Karen Ansel and Jessica Crandall ________.
| A．think highly of the latest popular diet book |
| B．like going to the gym often |
| C．think trying to lose weight isn’t good for a person’s body |
| D．are registered dietitians and work for ADA |
| A．it will do harm to their stomachs. |
| B．being overly hungry will make them feel not well |
| C．it may make them eat more |
| D．it might let them make bad decisions on important occasion |
| A．Because if they’re drunk, they can watch what they eat. |
| B．Because it will make it hard for their body to burn calories. |
| C．Because wine itself contains many calories. |
| D．Because it will make them feel more stressed. |
| A．Eating more vegetables than rice and other food. |
| B．Eating more cheese or cranberry sauce. |
| C．Never eat food with a lot of calories. |
| D．Sitting less and walking more after meals. |
| A．some advice on holiday eating | B．how to keep slim |
| C．the problems of fat people | D．what to do in holidays |
You may know the benefits of laughter on the mind and spirit. _1___ Norman Cousins used to say that laughter has such a good effect on your body that it is like “inner jogging”.

The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body’s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be “well” in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.
