根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

     Recently some American scientists have given a useful piece of advice to people in industrialized

countries. They say people should eat more of the same kind of food eaten by humans living more

than 10,000 years ago. 1_______

     The scientists say that human life has changed greatly. Our bodies have not been able to deal with

these changes in lifestyle and this has led to new kinds of sicknesses. 2_______ They are called "diseases

of civilization". Many cancers and diseases of the blood system arc examples of such diseases.

     The scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little

alcohol or tobacco, probably none. 3_______ However, a change in food is one of the main differences

between life in ancient times and that today.

     Stone Age people hunted wild animals for their meat,which had much less fat than domestic (驯养的)

ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy products,

and they made very little use of grains. 4_______ We eat six times more salt than our ancestors and we

eat more sugar as well. We eat twice as much fat but only one third as much protein (蛋白质) and much

less vitamin C. 

     5_______ But the scientists say that we would be much healthier if we cat much the same way the

ancient people did, cutting the amount of fat, salty and sweet food.

A. Stone Age people lived a simple life without any meat.

B. But today, we enjoy eating a lot of these.

C. In that case, they would live a much healthier life.

D. Ancient people also got lots of physical exercise.

E. These new sicknesses were not known in ancient times.

F. People today probably don't want to live like our ancestors.

G. Modern people used to suffer from "diseases of civilization".
