Q.13 Can we survive only on raw, leafy vegetables/grass? Discuss.

No, we cannot survive only on raw, leafy vegetables because :

1.They mainly consist of Cellulose which cannot be digested by us due to lack of cellulose digesting enzyme in our body.
2. We cannot get all required nutrients, such as carbohydrates, proteins, lipids, vitamins, and minerals, from them.
3. Moreover raw vegetables may not be digested easily as compared to cooked vegetables.
