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．  1

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．   2   So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases．

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 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．  4   We 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．

5   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"．

When you enter a supermarket, you see shelves full of food. You walk between the shelves. You carry a shopping basket with your food in it.
You probably hear soft, slow music as you walk between the shelves. If you hear fast music, you walk quickly. The supermarket plays slow music. You walk slowly and have more time to buy things.
Maybe you go to the meat department first. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk by all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.
The department selling milk and milk products such as butter and milk powder is called the dairy department. Many customers like milk that has only a little butter fat in it. One store has three different jars of low fat milk. One says “1 percent fat” on the jar. The second says “99 percent fat free”, the third says “Low fat” in big letters and “1%”in small letters. As you can see, all the milk has the same amount of fat. The milk is all the same. However, in this store the three jars of milk cost three different amounts of money. Maybe the customers will buy the milk that costs the most.
Most of the food in supermarkets is very pleasing. It all says “Buy me!” to the customers. The expensive meat says “Buy me” as you walk by. The expensive milk jar says “Buy me! I have less fat.”
