food keeps us alive .it is our sustenance and our pleasure.but recently ,research has shown that the eating habits of the average Americans may be dangerous to future health.the foods Americans now choose are often too rich in calories and fats,so this article reports a new study :diet and health ,implications for reducing chronic disease risk.
the study ,conducted by the national research council's committee on diet and health,concludes that balancing nutrietion,calories and activity is key to enjoying a long and healthful life.the report recommends that most Americans increase physical activity to a moderate leval and make changes in food choices and calories intake to maintain ideal weight.
most of us -even those of us of ideal weight-need to eat little fat so that no more than 30% of our daily calories will come from fat.
that means cutting down on red meat and whole milk dairy products.instead,eat fish,chicken without skin,lean meat,and low-fat and no-fat dairy products.
the report of the committee on diet and health recommends we eat five or more 1/2 cup servings of vegetable and fruits daily-especially green and yellow vegetables and citrus fruits.
eating more fruits and vegetable doesn't have to mean increased calries intake .many plant foods are nutruent-rich:they provide many vitamines and minerals for very few calories.
nutrient -rich foods are particularly important for Americans over 50 .as we age,we need to eat less because our bodies need fewer calories to function properly .but we still need full measures of vitamins and minerals to release the energy in our foods and make us feel strong and healthy.
