 Person2:  I'd rather say it's confusing . what are those " strict nutrition philosophies " about ?  
 Person1:      I believe they are careful calculations on proteins , vitamins and calories .  
 Person2:  Probably , Iris . That must be the job of nutritionists .  
 Person1:      Healthy eating is not about depriving oneself of the foods one loves . So we are free to have whatever foods we love . It is unbelievable .  
 Person2:  Oh , believe it or not , I came across an article the other day , saying that pizza is a healthy food .  
 Person1:      Seriously ?  
 Person2:  Yes , I felt exactly the same way as you did just now . Scientists must be crazy in saying so .  
 Person1:      Maybe nowadays people hold different opinions on healthy diet .  
 Person2:  Absolutely . I myself sometimes believe that healthy eating is just about feeling great . As long as I have enough energy , it's fine .  
 Person1:      But one must have some basic ideas about nutrition and find the best way for it to work out for the body .
