There have been a lot of changes in American eating habits in the last ten years. One is the growing awareness of the nutritional value of the food. Another is an increasing interest in a variety of international foods. Since about 1970, Americans have been more and more concerned about health. They have begun to notice the ingredients in what they eat.
    When they select food in the supermarket, they turn the packages over to read the labels carefully. They prefer to eat food that is produced without unnecessary chemicals and often choose fruits and vegetables grown without poisons used to kill insects. A small group of Americans, called vegetarians, has decided not to eat meat. They choose a complete diet from other kinds of food, because they think that meat products are not good for your health.
    Also more and more Americans have become interested in food from other countries. They have been going out to international restaurants and eagerly trying unfamiliar dishes. Chinese, Japanese, French, Italian, and Greek cooking, as well as many other recipes, are all popular these days in the United States. People used to say that Americans ate uninteresting, unhealthy food, but this has changed in the last ten years.
