Question

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

Answer 1

Hint: Cooked food is easily digestible then the raw food. The presence of cellulose in the grass which is a carbohydrate but still makes it difficult for us humans to digest, prohibiting this as food for us. However, the digestive system of cows is made in such a way that they easily digest raw food.

Complete answer:
We all know that leafy, green vegetables are good for our health and are nutritious too. Our body requires vitamins, minerals, fats, proteins and carbohydrates all of them in various amounts based on the body weight of different people.

As the leafy green vegetables do not contain all the nutrition required by our body to perform the various functions we will not be able to survive for a long time. Moreover, raw vegetables have the presence of cellulose in them and our digestive system is not made for its digestion unlike that of the cow. So we are unable to digest the raw food but cooked food is easily digestible.

The use of nutrients by an organism for harvesting energy, building body substances for growth and development and providing protection from diseases all comes undernutrition. The chemical substances that provide this nutrition in our food are called nutrients.

Thus the conclusion of the given answer is, No, we cannot survive only on raw, leafy vegetables/grass, because we cannot get all the required nutrients, such as carbohydrates, proteins, lipids, vitamins and minerals, from them. Moreover, raw vegetables may not be digested easily as compared to cooked vegetables.

Note:
- Nutriology is the term coined for the study of science that deals with nutrition. Basically it will expand on the study of food and the benefits it can provide to the human body.
- There is another term known as dietetics which is related to the study and regulation of diet. Depending upon the mode of nutrition, organisms are classified as either autotrophs or heterotrophs.
