Question

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

Answer 1

• Our bodies include various digestive glands that secrete digestive juices to help digest the various components of meals.
• For example, salivary glands create saliva, which breaks down carbohydrates into sugars, digestive juice in the stomach aids in the breakdown of proteins into amino acids, bile secreted by the liver aids in fat digestion, and so on.
• Raw, leafy vegetables and grass contain cellulose, a complex carbohydrate. Our bodies lack the necessary enzymes and digestive juices to digest cellulose.
• Our bodies cannot use cellulose as an energy source, so we cannot subsist solely on raw, green vegetables or grass.
