is it really necessary to add chese in salad diet ??

yuck there are very few salads i would even want cheese in and it would have to be certain kinds only!! i say if you dont like it and its not like what keeps it a certain texture (say if you were talking about a salad that is not lettuce but like fruit etc) then remove it.. doesnt make any sense if it so high in calories like you say

Often times when you are in a diet you neglect certain food groups. Remember, you want to lose weight and not nutrients, they incorporate chees so you can have a source of protein, calcium and some fat (you need these too). If you are going to eat all greens, you might end up calcium deficient, and protein deficient. :)

You can buy a low fat cheese, but I think its added because even though you are dieting you still need some good calories and since the salat it self is low in calories chesse adds them.
