下列哪一项不符合合理膳食的原则(  )

A.常吃奶类、豆类或其制品

B.不挑食,不偏食,膳食要清淡少盐

C.用高糖饮料或碳酸型饮料代替饮用水

D.经常吃适量鱼、禽、蛋、瘦肉,少吃肥肉和荤油

答案

合理营养是指全面而平衡的营养.“全面”是指摄取的营养素种类要齐全;“平衡”是指摄取的各种营养素的量要适合,与身体的需要保持平衡.为了做到合理营养,我国的营养学家将食物分为五类,并形象地设计成“平衡膳食宝塔”提倡居民每天均衡吃这五类食物,以避免营养不良和营养过剩.《中国居民膳食指南》基本原则:食物多样、以谷物类为主、粗细搭配;多吃蔬菜水果和薯类;每天吃奶类、大豆或其制品;常吃适量鱼、禽、蛋、和瘦肉;减少烹调油用量,吃清淡少盐膳食.高糖饮料或碳酸型饮料,营养价值不高.多数饮料都含有一定量的糖,大量饮用特别是含糖量高的饮料,会在不经意间摄人过多能量,造成体内能量过剩.另外,饮后如不及时漱口刷牙,残留在口腔内的糖会在细菌作用下产生酸性物质.损害牙齿健康.因此,选项C不符合合理膳食的原则.

故选:C.

     It's easy to see how to help others, but what about those whose needs aren't so obvious? This story

may have happened a while back, but it was a lesson which has stayed with me and helped me ever since.

It was Thanksgiving and I was volunteering with my parents at a shelter for the poor. We stood behind

the counter dishing out hot food to whoever came in. most of our dinners looked like they had been

having hard times, their clothes old, worn and dry. In short, they looked poor!

     Then, a man came in, who looked anything but poor. He was well dressed, wearing an expensive suit.

I wondered what he was doing there and my jaw dropped in amazement when he joined the line for food. The closer he came to my service station, the more I muttered. What was this man doing? I wanted to

know. Surely he wasn't gong to take food.

     Then my mother quietly took me to one side. She said, "You have assumed that the needs of the

people who come here must be purely physical: hunger, inadequate shelter and needs are emotional?

What if he needs comfort, friends, or just to be among other human beings?" her words hit me like a ton

of bricks! I felt like I should apologize to the man, but I didn't.

     About a week later the shelter received a large donation from an anonymous source. I can't help but

wonder if it came from that man.

     Now, whether I meet others, I remember my mother's words and try to send kindness and blessings

to them, regardless of how they look.

     Needs aren't always visible. But kindness always makes a difference.
