Modern science proves that a healthy lifestyle matters much to how long you can live and how well you live. Here are some tips for you to form a healthy lifestyle.

Keep a scientific diet. Keep in mind that sugar can be removed (去除) from our diet completely. Over intake (摄入量) of sugar is one of the main reasons for getting fat. Over intake of protein (蛋白质) or fat and low intake of fiber can also lead to getting fat. We only need a few grams of protein to keep our body in order.

Be always in a good mood. There is a relationship between the mood and health. A good mood keeps you in high spirits. Thanks to the Internet, we can enjoy and learn much without going out. Take a look at some online shops and pick up some bargains, enjoy music and movies and chat with good friends. Just keep happy.

Enough sleep. Two studies show the reasons why teens and adults don't have enough sleep. With teens, a major reason is mobile phone use;with adults, it's work. Meanwhile, a third study of young children shows that lack of sleep in early life may lead to serious problems in future. Everyone needs at least 8-hour sleep to recover (恢复) from tiredness and the hurt caused by hard work in the daytime.

Proper exercise. Do exercise to keep away from fatness. Because of the quick pace of the modern life, you don't have time to do exercise every day, but at least three times a week and 45 minutes each time.

Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they're in poorly lit places — and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

Mind the colours. Research suggests warm colours fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colours like yellow make food appear more appetizing, while cold colours make us feel less hungry. So when it's time to repaint, go blue.

Don't forget the clock — or the radio. People who eat slowly tend to consume about 70 fewer calories per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And well pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.

Certain microorganisms (微生物) cause most sorts of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release (释放) poisons that make people sick.

Some chemicals (化学制品) can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.

Some plants and animals contain natural poisons that are harmful to people. These include certain sorts of seafood, grains, nuts, seeds, beans, and mushrooms.

When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.

Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.
