Answer :Quick-cooking brown rice has been precooked (parboiled), so its ready in about a quarter the time as regular brown rice. Nicola McKeown, PhD, director of the Friedman Schools Nutritional Epidemiology Program, says, The advantage of quick-cooking brown rice is that it saves you time and you get all the whole-grain benefits. The quick-cooking variety of brown rice is a whole grain and is comparable to the regular variety with respect to dietary fiber, manganese, magnesium, selenium and fiber. McKeown adds that while brown rice is a healthier alternative to white rice, its also energy dense-so a recommended portion size is only half a cup of cooked rice.
