Health food is a general term applied to all kinds of food that is considered more healthy than the types of food sold in supermarkets.For example，whole grains，dried beans，and corn oil are health foods.A narrower classification of health food is natural food.This term is used to distinguish between types of the same food.Raw honey is a natural sweetener，while refined(提炼的)sugar is not.The most exact term of all and the narrowest classification within health food is organic food，used to describe food that has been grown on a particular kind of farm.Fruits and vegetables that are grown in gardens，that are treated only with organic fertilizers，that are not sprayed with poisonous insecticides(杀虫剂)，and that are not refined after harvest，are organic food.

In choosing the type of food you eat，then you have basically two choices：inorganic，processed(加工)food or organic，unprocessed food.A wise decision should include study of the reason why processed food contains chemicals，some of which are proved to be poisonous and that vitamin content is greatly reduced in processed food.

Bread is typically used by health food supporters as an example of a processed food. First, the seeds from which the grain is grown are treated with a chemical which is extremely harmful. Later, the grain is sprayed with a number of very deadly insecticides. After the grain has been made into flour, it is made white with another chemical which is also poisonous. Next, a dough conditioner is added along with a softener. The conditioner and softener are poisons，and in fact, the softener has sickened and killed experimental animals.

A very poisonous antifungal compound is added to keep the bread from getting moldy(发霉的)．

Other food from the supermarket would show a similar pattern of processing and preserving. You see, we buy our food on the basis of smell, color, and texture, instead of vitamin content, and manufacturers give us what we want, even if it is poisonous. The alternative? Eat health foods，preferably the organic variety.

In the old days, children were familiar with birth and death as part of life. Now this is perhaps the first generation of American youngsters who have never been close by during of the birth a baby and have never experienced the death of a family member.
　　Nowadays when people grow old, we often send them to nursing homes. When they get sick, we send them to a hospital, where children are forbidden to visit patients— even when those patients are their parents. This deprives（剥夺）the dying patient of family members during the last few days of his life and it deprives the children of an experience of death, which is an important learning experience.
　　Some of my colleagues and I once interviewed and followed about 500 in order to find out what they could teach us and how we could be of more benefit, not just to them but to the members of their families as well. We were most impressed by the fact that even those patients who were not told of their serious illness were quite aware of its potential outcome.
　　It is important for family members, and doctors and nurses to understand these patients’ communication in order to truly understand their needs, fears and fantasies. Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly about their trouble. Many of them shared with us their reat need to be informed, to be kept up-to-date on their medical condition and to be told when the end was near. We found out that patients who had been dealt with openly and frankly were better able to deal with the coming of death and finally to reach a true stage of acceptance before death.

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.  

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses （球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.  

There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.  

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.
