ALONG with the start of the new semester,many students will have to eat their breakfasts on the way to school or have dinner in the cafeteria.But some of them don't really know how to eat well when eating out.
There are several important tips.The first is to try not to eat fast food as much as you can.The most obvious harm of eating too much fast food is weight gaining.Teens as well as adults are at risk of disease related to weight
Too much fast food can drag your body down in other ways.French fries (炸薯條),for example,were recently found to contain much more acrylamide (丙烯酰胺) than other food.This may cause cancer (癌癥).In the US nine fast-food companies were sued (起訴) for not telling the public that their potato chips contained this unhealthy chemical.Actually,deep fried food all contains acrylamide.So don't eat it too often.
Soda is another thing you may want to watch out for.Cokes and other sodas (碳酸飲料) contain a lot of sugar and slow down a person's calcium absorption (鈣質(zhì)吸收).Even diet coke (無糖可樂) can cause this problem,so it's best to drink as little soda as possible
Food in the cafeteria at school may not be as tasty as fast food,but it's actually easier to make healthy choices.Human bodies need variety.You can arrange a dinner that balances lean proteins,vitamins and complex carbohydrates (淀粉食品).In other words,a meal with fish or meat,vegetables and some steamed bread (饅頭) or rice will provide you with most nutrients (營養(yǎng)) that the body needs.
Some snacks,on the other hand,will help keep you going until your next big meal.It is natural for teenagers,especially boys,to feel hungry a lot during school time.Don't be embarrassed; take some foods,like whole-grain biscuits (全麥餅干) or low-fat yogurt (酸奶) in your school bag.
隨著新學(xué)期的到來,很多學(xué)生就只能在上學(xué)路上吃早餐了,或者是在學(xué)校食堂吃晚餐.可是,很多人都不知道在外面吃飯時怎么才能吃的健康.
有以下重要的幾點需要注意.首先,盡量不要吃太多快餐食品.快餐食品吃的過多,最明顯的危害就是體重增加.青少年和成年人一樣,也面臨著因體重而產(chǎn)生相關(guān)疾病的危險.
食用快餐食品過多,你的身體狀況會出現(xiàn)滑坡.比如,最近發(fā)現(xiàn),法式炸薯條的丙烯酰胺含量比其它食品要多很多.它有可能會引發(fā)癌癥.在美國,有九家快餐公司被起訴,因為他們沒有告知公眾,他們的薯條中含有不健康的化學(xué)制品.其實,所有的油炸食品都含有丙烯酰胺.因此,不要經(jīng)常吃這些食品.
另外一種需要注意的食品是蘇打.可樂和其它碳酸飲料都含有大量糖份,會降低人體對鈣質(zhì)的吸收.即使無糖的可樂也會引發(fā)這個問題,所以,最好盡量少喝蘇打飲料
食堂里的食物可能沒有快餐那么好吃,但是,它們其實更容易吃出健康搭配.人體需要多樣化的攝取.你的晚餐中可以均衡搭配低蛋白質(zhì)、維他命和淀粉食品.換句話說,如果吃飯時有魚或者其它肉類,有蔬菜和饅頭或者米飯,那么就能提供身體所需的大多數(shù)營養(yǎng)成分.
此外,吃正餐前如果太餓,你可以先在一些小吃店吃點東西.對于青少年來說,尤其是男孩子,在學(xué)校里常常有饑餓感是很正常的.不要不好意思；在書包里裝點全麥餅干或者酸奶之類的食物即可.
