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.|
