This is not caused by nutritional deficiency in rice grain itself, but due to it being traditionally eaten in the form of the milled white kernel. Milling of the brown rice to obtain milled rice removes bran layers that are rich in protein, fiber, oil, minerals, vitamins, and other phytochemicals, leading to loss of most of the nutritional components of the rice grain. Numerous studies have shown that the essential phytochemicals in fruits, vegetables and cereal grains, including rice, are significantly associated with reduced risk of developing chronic diseases such as cardiovascular disease, type 2 diabetes, and some cancers (Liu, 2007; Yawadio et al., 2007; Yokoyama, 2004).
