Question 13:

Can we survive only on raw, leafy vegetables/grass? Discuss.


Raw leafy vegetables and grass are rich in cellulose, a type of carbohydrate. Many animals, including humans, cannot digest cellulose, because they do not have enzymes and certain type of bacteria which can digest cellulose. We cannot survive by taking vegetables in raw form. that՚s why we boil or cook vegetables which breaks down cellulose into simple carbohydrates. We can only survive by taking in vegetables in boiled/cooked form.
