Recently some American scientists have given a useful piece of advice to people in
industrialized nations. They say people should eat more of the same kind of food eaten by
humans living more than 10,000 years ago. 36.
The scientists say that the human life has changed greatly. Our bodies have not been able
to deal with these changes in lifestyle and this had led to new kinds of sicknesses. 37.
So they are called “diseases of civilization”. Many cancers and diseases of the blood system are
examples of such diseases.
Scientists note that people in both the Old Stone Age and the New Stone Age enjoyed
very little alcohol or tobacco, probably none. ver, a change in food is one of the
main differences between life in ancient times and that of today.
Stone Age people hunted wild animals for their meat, which had much less fat than
domestic 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. eat six times
more salt than our ancestors. We eat more sugar. We eat twice as much fat but only one third as
much protein and much less vitamin C.
40.____ But scientists say that we would be much healthier if we eat much the same
way the ancient people did, cutting the amount of fatty, salty and sweet food.
A. Stone Age people lived a simple life.
B. But today, we enjoy eating a lot of these.
C. In that case, they would live much healthier.
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”.
