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 (炸薯条),for example,were recently found to contain much more acrylamide (丙烯酰胺) than other food.This may cause cancer (癌症).In the US nine fast-food companies were sued (起诉) 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 (碳酸饮料) contain a lot of sugar and slow down a person's calcium absorption (钙质吸收).Even diet coke (无糖可乐) 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 (馒头) or rice will provide you with most nutrients (营养) 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 (全麦饼干) or low-fat yogurt (酸奶) in your school bag.
随着新学期的到来,很多学生就只能在上学路上吃早餐了,或者是在学校食堂吃晚餐.可是,很多人都不知道在外面吃饭时怎么才能吃的健康.
有以下重要的几点需要注意.首先,尽量不要吃太多快餐食品.快餐食品吃的过多,最明显的危害就是体重增加.青少年和成年人一样,也面临着因体重而产生相关疾病的危险.
食用快餐食品过多,你的身体状况会出现滑坡.比如,最近发现,法式炸薯条的丙烯酰胺含量比其它食品要多很多.它有可能会引发癌症.在美国,有九家快餐公司被起诉,因为他们没有告知公众,他们的薯条中含有不健康的化学制品.其实,所有的油炸食品都含有丙烯酰胺.因此,不要经常吃这些食品.
另外一种需要注意的食品是苏打.可乐和其它碳酸饮料都含有大量糖份,会降低人体对钙质的吸收.即使无糖的可乐也会引发这个问题,所以,最好尽量少喝苏打饮料
食堂里的食物可能没有快餐那么好吃,但是,它们其实更容易吃出健康搭配.人体需要多样化的摄取.你的晚餐中可以均衡搭配低蛋白质、维他命和淀粉食品.换句话说,如果吃饭时有鱼或者其它肉类,有蔬菜和馒头或者米饭,那么就能提供身体所需的大多数营养成分.
此外,吃正餐前如果太饿,你可以先在一些小吃店吃点东西.对于青少年来说,尤其是男孩子,在学校里常常有饥饿感是很正常的.不要不好意思；在书包里装点全麦饼干或者酸奶之类的食物即可.
