When the idea of having some snack foods comes to mind, there’s a good chance that you will think of a bag of potato chips at once. Yes, potato chips are one of the most common snacks in our daily life. They are very popular among both children and adults. It’s very easy for us to eat a whole bag of chips in a few minutes. But have you ever stopped and thought about what exactly happens to your body when you eat potato chips, especially if you eat a big bag every day?
If you eat potato chips every day, you are likely to put on weight. A study shows that people who have potato chips as a part of their diets gain weight easily. It’s no wonder they are on the list of snacks that cause you to gain weight.
Studies have also shown that a high intake of sodium (钠的大量摄入) is connected with a higher risk of high blood pressure. One of the main components (成分) of potato chips is sodium. If you often eat potato chips, over time, you’re going to end up developing high blood pressure.
Besides, you could increase the risk of getting cancer. This seems a bit extreme (极端的). However, according to the American Cancer Society, potato chips have acrylamide, something that is created in high-starch (高淀粉) foods when they’re cooked in hot oil, over a fire, or in an oven. Studies on mice have shown that it has something to do with cancer.
Thinking about all these, what should you do then? Just take it easy. You needn’t worry too much. If you can limit yourself to a small, snack-size bag of potato chips once in a while, instead of eating a large bag every day, you’ll be fine.

【推荐2】Welcome to China. We’ll invite you to eat the real Chinese food—dumplings. In China, there’s many different kinds of foods. Some of them are very popular. The real Chinese food is dumplings. Now let’s talk about them, OK?
Everyone in China likes dumplings very much, and there are many different kinds of dumplings. Some have meat and vegetables in them, others have sugar, eggs and so on. I like dumplings with vegetables and pork better than any other kind.
Usually people make dumplings at home. If you have no time to make them, you can buy them from any supermarket. Then you take them home and eat them with vinegar.
Spring Festival is very important in China. When it comes, we make dumplings and usually put a coin in one dumpling. If one eats the dumpling with the coin in it, he will be lucky in the year. In the old days, people couldn’t often eat dumplings, because they were very poor. Now our country is becoming stronger and stronger, and our people are richer and richer. We eat them often.
To our surprise, many foreigners also like eating dumplings. But they have problems in making dumplings, so they often go to Chinese restaurants to eat dumplings instead of making them at home.
Now tell me, do you like dumplings? What kind of dumplings do you like best?

【推荐3】People with an impulsive personality refer to those who tend to do things without considering the possible dangers or problems first. According to a new study by researchers at the University of Georgia, such people may be more likely to have food addiction. The study found that people exhibiting impulsive behavior weren’t necessarily overweight, but impulsiveness was related to a direct relationship with food, and therefore, less healthy weight.
Food addiction has been compared to addictive drug use. Studies have linked the dopamine(多巴胺)release that occurs after tasting delicious food to the dopamine release that happens when people consume other addictive substances.
Impulsive behavior involves several personality traits(特点). Two of these traits, known as negative urgency and lack of perseverance, were particularly associated with food addiction and high BMI(身体质量指数)during the study.
Negative urgency is characterized by the tendency to behave impulsively when experiencing negative emotions. Some people might drink alcohol or take drugs. For others, it could mean eating to feel better. Lack of perseverance is when a person has a hard time finishing hard or boring tasks. People with a lack of perseverance might have difficulty attempting to change addictive eating behavior, which could also cause obesity.
“Impulsiveness might be one reason why some people eat in an addictive way despite motivation to lose weight,” said Dr. Ashley Gearhardt, a clinical psychologist. He was involved in developing the Yale Food Addiction Scale in aid of those people. “We are theorizing that if food addiction is really a thing, then our measure, the Yale Food Addiction Scale, should be related to helping control impulsive action,” said Gearhardt.
Clinical psychologist Dr. James MacKillop, whose lab was conducting the study, believes that therapies used to treat addictive drug behaviour could help people who suffer from addictive eating habits.
“Most of the program for weight loss at this point focus on the most obvious things, which are clearly diet and exercise,” MacKillop said. “It seems that managing strong desires to eat would naturally fit in with the skills a person would need to eat healthily.”

A warm drink of milk before bed has long been the best choice for those wanting a good night’s sleep. But now a study has found it really does help people nod off — if it is milked from a cow at night.
Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.
The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night. Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.
Night milk quickened the start of sleep and caused the mice to sleep longer.
While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.
Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

【推荐3】Healthy eating doesn't just mean what you eat, but how you eat. Here is some advice on healthy eating.
Eat with others. It can help you to see others' healthy eating habits. If you usually eat with your parents, you will find that the food you eat is more delicious.
Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty--sometimes you are just thirsty, and you need no food. Stop eating before you feel full.
Eat breakfast. Breakfast is the most important meal of the day. Because you don't eat for the past ten hours, your body needs food to get you going. You will be smarter after eating breakfast
Eat healthy snacks like fruits, yogurt(酸奶) or cheese. We all need snacks sometimes. In fact, it's a good idea to eat two healthy snacks between your three meals. This doesn't mean that you can eat a bag of chips instead of a meal.
Don't eat dinner late. In our busy life, we always put off eating dinner until the last minute. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8-10 hours.

【推荐1】Roger Sperry and Robert Ornstein of the California Institute of Technology won a Nobel Prize in 1972. They discovered that the human brain has two sides, and each side has different work to do. The left side of the brain controls language and number; it analyses and reasons. The right side controls our imagination; it controls our understanding of music and our sense of rhythm. It is the right side of our brain which makes daydreams.
Great artists and great scientists are similar: they both use the two sides of their brain. It is well-known that Albert Einstein, as a great scientist, also enjoyed art, playing the violin and sailing. Einstein said his scientific discoveries grew from his imagination rather than from analysis, reason and language. He said that written and spoken words were not important in his thinking. He got ideas by using his imagination. He then used the left side of brain to use analysis, number and reason and then he used language to explain it.
Usual education in schools encourages us to use the left side of our brains. Language, number, analysis and reason are given more importance in our schools than imagination and daydreaming. However we are encouraged to hop when we have two perfectly good legs! Then why don’t we focus more attention on visual thinking?
In fact, all of us need both sides of our brain. We need to use our imaginations to think of solutions to problems and to enjoy feeling and creative experiences. And we need to be logical and to be able to analyze and organize in order to live in this world.
It is true that some people find it easier to use one side of the brain rather than the other but all of us can use both sides and all of us benefit by using all the powers we have.

【推荐2】As we all know, water is one of the most important things in the world. But we are short of water. The company Watergen produced a new machine to help work out this problem. The machine is called GENNY, it is small enough to be used in a home or office but can produce up to 30 liters of water a day. More importantly, it can produce clean water out of air.
GENNY takes air in and passes it through a filter (过滤器) to clean away dirty things. The filter is powerful enough to work even in areas with high air pollution. The air then passes through a room, then vapour in the air turns into water by heating and cooling in the room. The water is then passed through some more filters, and minerals (矿物质) are added to make it healthier and better-tasting. Finally, the water is kept fresh in a tank (大容器). As a company, Watergen plans to provide safe drinking water to millions of people.
Besides, Watergen tries to help the environment (环境) by encouraging people to use fewer plastic (塑料) bottles. People can put the water from jenny into glass bottles so that they won’t use plastic bottles any more. It calls for saving energy at the same time. There are even two kinds of jenny: one uses the electrical power and the other runs on energy from solar power.
The new machine of Watergen is sure to help many people around the world and help take care of our earth.

Chopsticks are pairs of sticks with the same length that have been used as kitchenware in most of the eastern Asian regions for over three thousand years. According to the historical study, the first chopsticks were thought to appear in China over 5,000 years ago. During the Spring and Autumn Period, chopsticks made of copper and iron developed gradually. Later the chopsticks with coating came in the Han Dynasty. Then gold and silver chopsticks followed.
Different materials have been used to make chopsticks until now, among which the most expensive ones are made of elephant teeth and the green stone. Those showed how wealthy the owners were.
It was said that silver chopsticks would turn black immediately if they touched poisoned food (but we know it was wrong today), so in history many kings and emperors used silver chopsticks to check whether the food was bad for them or not before eating. Chopsticks are also regarded as gifts to others. In China, chopsticks are traditionally given to a daughter when she marries, to hope that they will have a child very soon, because the pronunciation of word “chopsticks” in Chinese is like “quick child”. Meanwhile, people often believe chopsticks have something to do with good luck. So many families will choose to put new chopsticks on the table at dinner on New Year’s Eve as a way of wishing for luck while dropping chopsticks is a sign of bad luck to come.
It’s believed that using chopsticks can increase fingers’ flexibility. That means if we use chopsticks frequently at dinner, it will make our fingers do everything freely. Some experts also prove that it can improve memory. Many westerners, businessmen and tourists put their knives and forks beside the bowls and plates but choose chopsticks in China.

【推荐2】If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven’t you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles (肌肉).
The study also found the effect (效果) is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals” who had learnt a second language before the age of five, as well as a number of later learners. Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference. “Our findings suggest that the structure (结构) of the brain is changed by the experience of learning a second language,” said the scientists.
It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and math skills. “Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),” he said. “You are actually going beyond language and have a better understanding of different ideas.” The findings had the same result in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.
