germinated grams are consideredhighly nutritive.

what is the reason for this belief?

The process of germinating or sprouting seeds basically involves providing hydration to dry seeds so that they start the process of germination. During this process all the complex food stored in the seed in the endosperm starts breaking down by increased activity of hydrolytic enzymes. This breaks the food down and increases the amount and quality of fatty acids, proteins and other vitamins which are highly nutritious.
