what is the difference between white and brown rice, and why is brown rice better for diebetics?

Answer 1

Milling is the process that creates the difference between brown and white rice. The variety of rice may be identical, but milling removes the husk from the grain and turns the brown rice to white. By removing the outer layer, which is also known as the bran layer, milling alters the nutritional value of the rice. It is in this bran layer where most of the nutrients are stored. The white rice that most of us eat comprises of mostly carbohydrates, with the nutrients stripped off in the milling process. Carbohydrates are broken down into sugar inside the body. While carbohydrates are a good source of energy (yielding 4 calories per gram), excessive carbohydrate intake leads to sugar imbalance and adult onset diabetes mellitus.
Fiber in brown= 3.32 g and in white= 0.74 g and other differences can be found on this website.

Answer 2

White rice spikes your insulin, whereas brown rice does not. Insulin spikes promote fat storage.
