1 Eat for a Good and
Healthful Life

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 oftentimes 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 nutrition, calories and activity is key to enjoying a long and healthful life.
The report recommends that most Americans increase physical activity to a moderate level and make changes in food choices and calories intake to maintain ideal weight.
Most of us — even those of us at ideal weight — need to eat less 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. Indeed, eat fish, chicken without skin, lean meats, 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 vegetables and fruits daily — especially green and yellow vegetables and citrus fruits.
Eating more fruits and vegetables doesn’t have to mean increased calories intake. Many plant foods are nutrient — rich; they provide many vitamins 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. [卫生类C]

为好而健康的生活而吃饭

食品维持着我们的生存。它是我们的营养品也是我们的乐趣。但近来的研究表明,普通美国人的饮食习惯对未来健康可能是危险的。
美国人现在所选择的食物常常富含卡洛里和脂肪。所以这篇文章将报道一项新的研究:饮食与健康,减少慢性病风险的暗示。
这次由国家卫生饮食调查委员会进行的调查得出的结论认为:营养的均衡、卡洛里以及活动是健康长寿的关键。
报告建议大多数美国人把活动提高到一个适当的程度并且要改变对食物的选择和卡洛里的摄入以保持理想的体重。
大多数人——甚至那些体重理想的人——必须少吃脂肪,以使我们所摄入的脂肪的卡洛里不超过30%。
这意味着少吃牛羊肉以及各种各样的乳品。确实,要吃些鱼,不带皮的鸡肉、瘦肉以及低脂肪的或脱脂肪乳制品。
卫生饮食委员会建议大家每天吃5份或5份半的水果和蔬菜——特别是绿色和黄色蔬菜以及柑橘类水果。
吃更多的水果和蔬菜不一定就意味着卡洛里摄入量的提高。许多来源于植物的食品维生素和矿物质很多,含热量却很少。
对于50岁以上的美国人,营养丰富的食品尤为重要。当我们变老时,我们必须吃得更少,因为我们的身体发挥正常机能所需的卡洛里减少。但我们仍然需要从食物中获得足量的维生素和矿物质来释放能量,以使我们健康强壮。[卫生类C]
