Rice wheat are both staple cereals in Indian diet. Unfortunately while wheat is generally eaten as a whole grain cereal (atta), rice is usually eaten polished. Polished white rice is not as nutritious as it looses most of the grain fibre, vitamin, mineralsand protein. However, if you take brown/unpolished rice it is as good as whole wheat. The consumption of wheat/rice is largely dependent onclimatic factors. While wheat requires a colder climate, rice requires warm, humid and rainy climate.
