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. [衛(wèi)生類C]

譯文：為好而健康的生活而吃飯

食品維持著我們的生存。它是我們的營養(yǎng)品也是我們的樂趣。但近來的研究表明，普通美國人的飲食習(xí)慣對未來健康可能是危險的。

美國人現(xiàn)在所選擇的食物常常富含卡洛里和脂肪。所以這篇文章將報道一項新的研究：飲食與健康，減少慢性病風(fēng)險的暗示。

這次由國家衛(wèi)生飲食調(diào)查委員會進(jìn)行的調(diào)查得出的結(jié)論認(rèn)為：營養(yǎng)的均衡、卡洛里以及活動是健康長壽的關(guān)鍵。

報告建議大多數(shù)美國人把活動提高到一個適當(dāng)?shù)某潭炔⑶乙�改變對食物的選擇和卡洛里的攝入以保持理想的體重。

大多數(shù)人——甚至那些體重理想的人——必須少吃脂肪，以使我們所攝入的脂肪的卡洛里不超過30％。

這意味著少吃牛羊肉以及各種各樣的乳品。確實(shí)，要吃些魚，不帶皮的雞肉、瘦肉以及低脂肪的或脫脂肪乳制品。

衛(wèi)生飲食委員會建議大家每天吃5份或5份半的水果和蔬菜——特別是綠色和黃色蔬菜以及柑橘類水果。

吃更多的水果和蔬菜不一定就意味著卡洛里攝入量的提高。許多來源于植物的食品維生素和礦物質(zhì)很多，含熱量卻很少。

對于50歲以上的美國人，營養(yǎng)豐富的食品尤為重要。當(dāng)我們變老時，我們必須吃得更少，因?yàn)槲覀兊纳眢w發(fā)揮正常機(jī)能所需的卡洛里減少。但我們?nèi)匀恍枰獜氖澄镏蝎@得足量的維生素和礦物質(zhì)來釋放能量，以使我們健康強(qiáng)壯。[衛(wèi)生類C]
