You probably know the food pyramid (金字塔) well enough. It is a food pyramid with horizontal stripes (水平线). Carbohydrates (碳水化合物) , such as bread, rice and potatoes, are on the base of the pyramid. They are most of our everyday food. The fats and oils (脂油) are at the top of the pyramid. We should eat the least of them.

　　Well, the food pyramid has been built again and it looks a lot better. It is a food pyramid with vertical stripes (垂直线). Instead of the horizontal stripes, the vertical stripes mean the five food groups and fats and oils. Another change is that the stripes get thinner at the top of the pyramid. This is because not all foods in a food group give us the same health benefltS (好处). A fresh apple, for example, would be on the base of the pyramid, while an apple pie would be at the top. This shows that we can eat more fresh apples than apples in an apple pie. Another big change is the steps (阶梯) going up the side. This shows us how important exercise is. It also shows us that we will be healthier and healthier if we take exercise every day.

　　So why did some American experts change the pyramid? They did this to do a better job of telling people how to be healthy. The new pyramid tells us to have balanced (平衡的) food from each food group every day, and it shows us that we need less of some kinds of food than others. For example, you need less meat or fish than rice or fruit. It also shows us that not all foods in a group give us the same health benefits, and that exercise is quite important in our everyday life.

     A special kind of *flu (H1N1) is now *spreading in many countries, including China. So it’s important to know how to stop catching flu and cold. Here are some suggestions on how to keep away from flu.

1. Wash your hands often. The flu, as with colds, is spread from person to person. The way these *germs are spread is not by breathing them, but by picking them up on our hands and spreading them to our face where they can get into your body. So please remember: wash your hands often and don’t touch your eyes, nose, or mouth.

2. Get enough sleep. Enough sleep is important to the health. Enough sleep will make you energetic and active again. More important than how long you sleep is when you sleep. Studies show that the best spring or summer bedtime is between 9 and 10 p.m. and the best autumn or winter bedtime is between 8 and 9 p.m.

3. Drink water every day. Water helps change food into energy. Water also helps clean out your body. After a night’s sleep, your body really needs water. So it’s important to drink some water after you get up every morning. And drinking enough water could keep your balance of salt. But don't drink water much more than you would, or should.

4. Eat a healthy, balanced diet. Scientists have found out that what people eat affects their health. They advise people to keep a balanced diet and that is to say, you should eat more fruits and vegetables and less meat such as beef and pork. You should also eat less food that is high in fat, like French fries or cookies.

5. Do more exercise. It is surely necessary to take some exercise every day. Studies show that getting lots of exercise makes the heart healthier. That’s why more and more people are becoming active in all kinds of sports and exercise. Through sports and exercise, people become healthier and stronger. So in the morning, you can get up early, go outdoors, breathe the fresh air, and do exercises. When we exercise, our body produces special chemicals that give us energy, and exercise also helps improve our body’s *ability to fight disease.
