Milk has become a popular drink for modem Chinese, not only is its nutritional(营养的) value appreciated, it seems even to have taken the role making the whole nation strong. Milk industry has only about 180 years of history among the Hah people. For a long time, milk was considered a luxury(奢侈的) drink by common people. A widespread saying in the country was that Japan used a cup of milk to strengthen the constitution(体格) of its people. That sounds reasonable because the rich "Ca" in milk definitely benefits the constitution.

The average annual consumption per capita in Japan has risen from less than 10 kilograms immediately after World War II to 68 kilograms today. The average height of Japanese has increased by 11 centimeters during this period. The Chinese Government also hopes to improve the constitution of local people, and since milk is the most obvious nutritious food, it has naturally been picked up. But due to tradition, Chinese people are not in the habit of drinking milk regularly. The annual output of milk in the country is about 10 million tons, compared with an output of alcohol reaching 8 million tons. The annual milk consumption per capita is about 7 kilograms in China while the world's average is about 100 kilograms. The government has noticed the huge gap and plans to raise consumption to 10 kilograms per capita by 2005 and 16 kilograms by 2010. The government has also started plans for "school milk" since the beginning of this century.

Chinese government encourage people to drink milk and hope that ______.

A．the whole nation will become stronger

B．the milk industry will have a faster development

C．milk will no longer be considered a luxury drink

D．its nutritional value will be more appreciated

Facts About Food

Everywhere on earth there are"food specialists"with opposite (or different) opinions on the best kinds of nutrition for various purposes. A lot of people believe that the healthiest diets are high in fiber ,vitamins ,and minerals but low in fat ,cholesterol ,sugar,and salt. Some nutritionists say the perfect eating plan contains mostly carbohydrates without much protein. In contrast , other scientists say people need high-protein meals with meat, chicken , fish , or milk products and only small amounts of grains , potatoes , breads , rice , and noodles. One famous diet plan allows only certain foods at certain times-protein with protein, carbohydrates with carbohydrates , fruits alone , and so on. Some eaters stay away from all meat and maybe even fish and milk products. They get their protein from plants , mostly beans. Others want only high-fiber food. These people may not eat white bread or white rice or even cooked vegetables. So what is the best way to eat and be healthy？ The discussion of food facts will go on far into the future.

The necessary substances and elements for human life and health are water, protein, carbohydrates ,fats , vitamins, and minerals. Most kinds of food contain some or all of the required nutrients , but these substances have different effects on people. Various ingredients and dishes affect the mind in different ways. and some kinds of nourishment have better effects on the brain than others. For instance. can broccoli increase brain power？ Maybe so. Low levels of some of the B vitamins can cause a decrease in memory and thinking ability , nutritionists say, but dark green vegetables , like broccoli , contain a lot of these nutrients. Another example of a"memory helper"is lecithin-a substance from soybeans , also found in high-fiber foods like nuts and whole grains. High-protein foods influence the mind in more helpful ways than dishes high in sugar and carbohydrates. And the caffeine in coffee or tea may help thinking. Of course , its effects don't last long.

In many places outside big cities , food with more than four legs is part of good, healthy home cooking. Fried or grilled ants are a tasty but expensive snack in Colombia , South America. In various parts of Mexico , over 300 types of insects serveas food. In southern Africa. many people like to eat at least one kind of caterpillar or worm. They enjoy it fried , dried , or cooked in tomato sauce. In Thailand , cooks create a spicy hot pepper sauce with water bugs. In Vietnam , grasshoppers filled with peanuts are a special dish. And in some regions of China,bugs are not only a part of meals but an important ingredient in medicine too. Most kinds of insects have high nutritional value. They contain a l0t of protein , vitamins , and minerals. Many people like their taste. They are everywhere on the planet. They add to the variety of people' s diets. For several reasons , insects are an important kind of food in the global diet , and they may become a more common ingredient in the future.

The growing similarities in diet and eating habits around the world are influencing people of various cultures in different ways. For example, Western foods are damaging health in the industrialized island country of Japan. Instead of small meals of seafood , rice , and vegetables ,the typical Japanese diet ow includes large amounts of meat ,dairy products. And desserts like tiramisu , a rich Italian dish full of chocolate , cheese , and sugar. According to Japanese health researchers , such changes in eating habits are related to a great increase in health problems such as heart disease , strokes , cancer , and diabetes. On the other hand , the changing global diet is having the opposite effect on the people in the Czech Republic. The government of this European nation no longer supports meat and dairy products financially , so the cost of these foods is going up. In contrast , fresh fruits and vegetables are becoming more widely available from private markets and stands. Cooks are even serving salads to schoolchildren ,and families are eating healthier home-cooked meals. For these reasons ,fewer Czech men are having heart attacks , the women are l0sing a l0t of weight , and most people are living healthier lives.
