Sometimes, people are not clear about what kind of food is healthy and what kind of food may do harm
to our health. The USDA has prepared a food guide to help people learn about which kind of food is the
healthiest to eat. The food guide describes six main food groups: meat ( like fish and chicken), dairy ( like
milk and cheese),grains (like bread and rice),fruit, and vegetables. The last group is fats and sweets. The
USDA also suggests how much of each food group is healthy to eat daily. Though this guide was prepared
by the US government, it is very useful for people all over the world.
(1) As a result of years of study, we know that too much animal fat is bad for our health. For example,
Americans eat a lot of meat and only a small amount (量) of grains, fruit and vegetables. Because of the way
they eat, they have a high rate (率) of cancer and heart disease. In Japan, people eat large amounts of grains
and very little meat. The Japanese also have a very low rate of cancer and heart disease. The Japanese live
longer than anyone else in the world. However, when Japanese people move to the US, the rate of heart disease
and cancer goes up as their eating habit changes. And as hamburgers, ice creams and other high-fat foods
become popular in Japan, the rate of heart disease and cancer is going up there as well. (2) People are also
eating more meat and dairy food in other countries, in those countries the disease rate is going up with the
change of people's eating habit. Doctors everywhere suggest people eat more grains, fruit and vegetables and
less meat and dairy food.
(3) Eating healthily is important for children as well as their parents. When parents have poor eating habits,
their children usually do, too. After all, children eat the same way as their parents. When parents eat healthy
food, the children will learn to enjoy it, too. Then they will develop good eating habits. Doctors suggest parents
give their children healthier food such as fruit, vegetables and juice.
Everyone wants to live a long, healthy life. We know that the food we eat affects (影响) us in different
ways. For example, doctors believe that fruit and vegetables can really protect people from many different
diseases. On the other hand, animal fat can cause (引起) diseases. We can change our eating habits now and
enjoy many years of healthy living.
