Three Popular Foods in the US Convenience Foods Instead of buying only fresh foods, Americans buy many more convenience foods. These are foods which are ready partly or completely prepared. There are also many canned ( 罐头 ) convenience foods, such as soups and vegetables. Convenience foods save time and trouble. They are popular with people who are busy or who don’t like cooking or washing dishes. Health Foods In the 1960s, a “back-to-the earth” movement was started by young people in the US. The movement was a reaction against the harmful effects of technology. Many people now prefer natural and organic foods to the prepared foods sold in food stores. Diet Foods These days Americans are more and more concerned with their weight. American supermarkets sell a variety of diet foods as diet soft drinks, diet candy, and diet salad dressings. Each year dozens of new diets are popularized.
