单选题 Every time a person eats something he makes a nutritional decision. He accepts or rejects the food available to him at home for meals or snacks. Or he selects food for himself at many places in the community, such as supermarkets, drive-ins, restaurants, and food counters in drugstores. These selections make a difference in how an individual looks, how he feels, and how well he can work and play.
When a good assortment of food in appropriate amounts is selected and eaten, the consequences are more likely to be a desirable level of health and enough energy to allow one to be as active as one needs and wants to be, When choices are less than desirable, the consequences are likely to be poor health or limited energy or both.
Studies of diets of individuals in the United States show that food selection is a highly individual matter, even, among young children. Furthermore, far too many individuals of all ages ale making poor choices day after day and are either now living with the consequences or will be in the future.
Nutritionists and workers in allied professions have been concerned about helping people learn to select and enjoy a wide variety of food combinations that can add up to a good diet.
Most people believe that they are well fed-that the choices they make are good ones. After all, they are not really sick, neither are they hungry. However, their nutrition is usually poor in one respect or another. Milk and milk products, such as cheeses, ice cream or milk, buttermilk, and yogurt, are often slighted. Then people may skip many fruits and vegetables, particularly those that are good sources of vitamins A and C. These include dark green. Leafy vegetables; deep yellow vegetables; and citrus fruits and vegetables, such as cabbage, tomatoes, and green peppers.
Every American has the right to choose to be uniformed about nutrition as wall as to be informed. If a person believes that she is well fed, attitudes, habits, and information cannot be forced upon her.
There are life situations, however, that tend to cause all individual to want to know how to make the best choices. For example, a young couple is starting a family and must prepare food for young children.
