Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life.

Blue/Purple

Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants (抗氧化剂) that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight.

A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer.

Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc.

Foods that contain the green color are: broccoli, cabbage, cucumbers, etc.　

Red

Lycopene (番茄红素) in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks.

Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce."

Foods that contain red color are: Tomatoes and tomato products, watermelon, guava, red onions, red chili, red apples, red grapes, cherries, etc.

Orange

The orange foods are also rich in carotene, which are particularly good antioxidants. These foods are commonly considered eyesight foods because they contain vitamin A.

For as long as they can remember Jynne Martin and April Surgent had both dreamed of going to Antarctica. This winter, they each made it to the icy continent as guests of the National Science Foundation (NSF).But they didn’t go as scientists. Martin is a poet and Surgent is an artist. They went to Antarctica as participants in the NSF’s Artists and Writers program. The NSF is the government agency that funds scientific research in Antarctica. But it also makes it possible for artists, including filmmakers and musicians, to experience Antarctica and contribute their own points of view to our understanding of the continent.

The mixing of science and art in Antarctica isn’t new. Some of the earliest explorers brought along painters and photographers. Edward Wilson was a British painter, doctor, and bird expert who journeyed with Robert Falcon Scott on two separate Antarctic expeditions more than 100 years ago. Herbert Ponting was a photographer who also accompanied Scott on one of those expeditions. In hundreds of photos, Ponting captured the beauty of the continent and recorded the daily lives and heroic struggles of the explorers.

Today’s scientists write articles for scientific journals. Unlike the early explorers’ journals, scientific papers can now be very difficult for non-scientists to understand. Writers in Antarctica work to explain the research to the public. Peter Rejcek is editor, writer, and photographer for the Antarctic Sun, an online magazine devoted to news about the U.S. Antarctic Program. Rejeck began his career in the Antarctic in 2003 by spending a year at the South Pole. He has returned every year since，interviewing， scientists about research at Palmer，McMurdo，and South Pole stations.

There are also scientists in Antarctica who work hard to explain their research to the public. Scientist Diane McKnight wrote The Lost Seal，a children’s book that explains the research she and others are doing in an unusual ice-free area in Antarctica called the Dry Valleys.

Antarctica is full of stories and wonders that are scientific, historic and personal. People such as Martin, Surgent, Rejcek, and Diane McKnight are devoted to bringing those stories to as many people as they can. “Some people are going to be scientists，some people are going to be journalists，some people are going to be artists，but we can all work together.” says Surgent, “to celebrate，this extraordinary place.”

1.What do we know about the NSF?

A. It is a government agency.

B. It only funds scientists in Antarctica.

C. It encourages the understanding of human nature.

D. It enables the mixing of science and art for the first time.

2.Why didn’t some earliest explorers bring writers along?

A. Writers were not funded at that time.

B. Writing can’t capture the beauty of the continent.

C. Writers were not interested in popularizing science.

D. Early explorers ’journals can be easily understood by the public.

3.By mentioning Diane McKnight, the author may try to suggest that_____.

A. scientists should explain their research to children

B. writers are not necessary since scientists can tell stories as well

C. telling stories to children is more important than knowing the truth

D. no matter what role we play, we can work together to appreciate Antarctica

4.What would be the best title for this article?

A. Antarctica: A Land for A11

B. The NSF: A Program for All

C. Antarctica: A Land of Beauty and Stories

D. The NSF: A Program for Artists and Scientists
