You may think that drinking fruit juice is healthy. But that’s not quite true (真的). A study shows that drinking too much juice will cause many health problems. This is because these drinks have a lot of sugar. If a person takes in too much sugar every day, he or she is likely (可能) to have heart disease.

So some cities in the US make the price of sugary drinks much higher. They want to discourage people from buying them. Some scientists said that kids between 1 and 6 years old should not drink more than 170 ml of fruit juice each day. Kids over 6 years old should not drink more than 230 ml of fruit juice each day. It is important for us to control (控制) the sugar we take in every day.

Does this mean that eating fruit is also unhealthy? Don’t worry! Fruit is different from fruit juice. When you drink 100 ml of fruit juice, you’re eating more sugar than when you eat 100g of fruit. So, in order to keep healthy, you’d better eat fruit instead of drinking fruit juice.

3 . We have kept fighting against COVID-19 for more than three years. Nowadays, more and more people care more about their health than money. And the ways they take to keep healthy are different. Then, what are the good ways to keep healthy?     1    

First, we should keep in a good mood.     2     So, we need to try our best to keep in a good mood, or try to shorten the time we are in a bad mood.

Second, we should have enough sleep every day. We can study and work better when we sleep well. Don’t stay up late at night and get up early in the morning.

    3     We should eat more fresh fruit and green vegetables. They are good for our health. But we’d better never eat junk food. It’s really bad for our bodies.

Fourth, when we are at home, we should open the windows to keep the air fresh. We should change our clothes often.     4     In these ways, we can prevent the flu and other diseases.

Finally, doing sports every day can help build us up.     5     For example, we can go for a walk after dinner.

In a word, no matter which kind of methods we take to keep healthy, do not go far away from these basic ways. Only in this way, we can get a better effect.

4 . Your heart is very important in your body. It is working all the time, but it never gets tired. Sometimes people get heart disease. There is nothing they can do to stop it. However, there are things a person can do to keep his or her heart healthy.     1    

It’s necessary to exercise.     2     Exercise makes your heart beat faster, keeps it healthy and strong, and keeps your body strong, too.

    3     In our country, many people eat too many foods with a lot of fat and sugar. These foods increase (增加) a person’s chance of a heart disease. So, instead of eating fast food or junk food snacks, eat lots of chicken, fish, and vegetables that are good for you.

Don’t start smoking.     4     It cuts oxygen to your heart. It increases a person’s chance of getting a blood clot (血栓).

    5     Enough sleep is important to help people relax. Talking with your close friends or your parents can help you feel less worried.

Keeping your heart healthy helps your whole body healthy.

8 . Scientists in Japan have developed electric chopsticks that are designed to help people cut down on salt. Though human bodies need salt, many people eat far too much of it, which is unhealthy. It’s well known that eating too much salt can lead to high blood pressure, heart disease and so on. The special chopsticks use a tiny bit of electricity to make food seem saltier than it is.

Kirin, a Japanese company that sells food and drink, worked with researchers at Miyashita Laboratory to develop the chopsticks. The chopsticks have a battery pack that can be worn on the wrist (手腕). When the tips of the chopsticks are put in the mouth, a very light electric current (电流)—too small to be felt as a shock—changes the way the tongue (舌头) tastes certain chemicals.

Experiments showed that with the chopsticks, food could have up to 30% less salt and still taste just as salty. So far Kirin hasn’t announced plans to sell the chopsticks. But it is looking into ways the technology could be used with other eating utensils (餐具), including spoons.

9 . Kids are having more sugar and junk food in the US now.

They get sugar from sodas, sweet juice and some other drinks. There was a new study. It was on 8,400 children. They were between the ages of 2 and 19. It found that twenty percent of the children didn’t drink any water. That’s on any given day. It also showed that those kids got more calories (卡路里) from sweet drinks. That’s compared to children who did drink water every day. Children who do not drink water can have almost twice as many calories. “Kids should drink water every day. And the first drink for kids should be water because it is healthy,” said one teacher.

The study showed two thirds of the children have junk food for lunch for it is fast and delicious. Junk food, like hamburgers, hot dogs and French fries, makes children in the US overweight (超重) and brings many health problems. This is because it has lots of salt and sugar. Children who eat junk food four to five times a week are easy to have heart diseases. “Kids should keep a balanced diet with both vegetables and all kinds of meat because giving what our body needs is important,” said another teacher.
