How many parts?
Rice grain has three parts or layers: husk, bran, germ. In milling, the grain is de-husked. All varieties of rice undergo milling. The next layer is germ. All nutrients are stored in this. It has B.Vitamins, minerals and proteins. The upper layer is called bran. It is whitish in colour. This has key nutrients and B. Vitamins. But in polished white rice, all this is gone.
Difference in nutrient factor
Brown rice is where the bran and germ are not removed. But in white rice, these are removed. That is why, in brown rice, Magnesium and other minerals are found in abundance. If there is one gram of fibre is present in one cup of white rice, the same will be four gm, in one cup of brown rice. If fibre is adequate, the rate at which carbohydrates transform in to sugars, is reduced. GI is less in brown rice. Not just brown rice; GI is less in long grain variety of rice, compared to short grain. That is why brown rice is good for health. However, for children and aged persons, who have digestion problems, it is better to give light, polished rice.
