Healthy Diets
Instead of buying only fresh foods,Americans nowdays buy many more convenience foods.There are foods which are already partly or completely prepared .Many of them are frozen,such as frozen dinner,heat-and-serve French fries ,and frozen pizzas.There are also many canned (put in a can) convenience foods. such as ready-made spaghetti (意大利细条实心面),soups,stews (炖熟菜肴),and vegetables.
Convenience foods save time and trouble.They are popular with people who are busy or who don’t like to cook or wash dishes.But they ofen cost more than fresh ,unprepared foods and may contain artificial additives (a chemical added to the food).Also,many people feel they don’t taste as good as home cooked foods.
Health food and Co-ops
In the 1960s,a“back-to-the-earth”movement was started by young people in the United States.The movement was a reaction against the harmful effects of technology.From the movement came a new understanding of food and health.Many people now prefer natural and organic(chemical-free)foods to the prepared foods sold in health food stores and in food co-ops,which are small stores and where customers help manage the store .In co-ops,food is usually not packaged.Customers bring their own bags and jars and scoop(汲取) their food out of boxes or baskets.
