对话文本
I: Boris, look at this sentence."Healthy eating is not about strict nutrition philosophies, staying unrealistically thin, or depriving yourself of foods you love." It's interesting, isn't it?
B: I'd rather say it's confusing. what are those "strict nutrition philosophies" about?
I: I believe they are careful calculations on proteins, vitamins and calories.
B: probably, Iris. That must be the job of nutritionists.
I: healthy eating ia not about depriving oneslf of the foods one loves. So we are free to have whatever foods we love. It is unbelievable.
B: oh, believe it or not, I came across an article the other day, saying that pizza is a healthy food.
I: seriously?
B: yes, I felt exactly the same way as you did just now. Scientists muct be crazy in saying so.
I: Maybe nowadays people hold different opinions on healthy diet.
B: absolutely. I myself sometimes believe that healthy eating is just about feeling great. As long as I have enough energy, it's fine.
I: but one must have some basic ideas about nutrition and find the best way for it to work out for the body.|

参考翻译
鲍里斯,你听听这个句子:"健康的饮食不是指严格的营养哲学,不切实际的瘦身或是不吃自己爱吃的食物."这听起来蛮有意思的.
我倒不明白.什么叫做"严格的营养哲学"?
我觉得是指仔细计算蛋白质,维他命和卡路里.
有道理,爱瑞斯.那都是营养学家该干的事.
健康的饮食不是指不吃自己爱吃的食物.那我们就能随便吃自己爱吃的食物了吗?真是难以置信.
哎,你知道吗,前几天,我还读到一篇文章说披萨也是健康食品.
真的吗?
是啊,我当时的反映和你一样,觉得科学家都疯了.
也许现在人们对健康饮食的看法改变了.
是这样的.我有时候觉得吃得健康就是自己感觉好罢了.只要我精力充沛,就可以了.
但是我们还是要知道一些基本的营养知识,使各种营养元素在我们的身体中发挥作用.
