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 drug stores.（83）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 he 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.（84）Furthermore， far too many individuals of all ages are 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 really poor in one respect or another. Milk and milk products， such as cheese， icecream， buttermilk， and yogurt， are often neglected.Then people may leave out in their diets many fruits and vegetables， particularly those that are good sources of vitamins A and B.These include dark green，leafy vegetables; deep yellow vegetables; and citrus fruits and vegetables， such as cabbages， tomatoes， and green peppersThe passage mentions all of the following influences of food selection except _____（）
