Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning(中毒). 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 types 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 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 kinds 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 any 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.

Today, due to numerous medical and scientific advances, people are living longer than ever before. But you have to be good to your body, mind, and soul. The following tips are a good start for getting you on your way to living a long and healthy life.

Eat a balanced diet -- one that is rich in fruits, vegetables, whole grains, and fiber and low in saturated fat, trans fat, and cholesterol. A well-balanced diet can provide your body with the essential nutrients needed to achieve and maintain optimum (最佳的) health.

Be physically active -- try to incorporate 30 minutes of activity into your day, every day. The options are endless; start walking on the beach in the mornings, try jogging with a friend, or go for a bike ride in the afternoons. Make sure you choose activities that you enjoy, so that you'll be more likely to make them a habit.

Get regular preventive check-ups --see your doctor regularly; remember your doctor is your partner in health care. By having regular check-ups, you may be able to catch small problems before they become big ones.

Be safe - use common sense and be streetsmart (适应都市生活的). Don't put yourself in situations that are questionable. Always wear your seatbelt and bike helmet. Don't go for a run,   walk, or jog at night by yourself. Keep your home well lit and free of things that could make you fall.

Stay in touch with family and friends -- get to know your neighbors. Take the time to be involved with your community. By creating a strong social network, you will not only have friends to celebrate with when good things happen, but also a support system in difficult times.

Keep a positive attitude -- studies have shown that people who have a positive attitude tend to live longer, and lead healthier and happier lives. Try to find the humor in life. And remember to laugh.
