MND: Brown rice, everybody knows it is good for you. But how good, and is there any risk?

Brown rice is white rice with it’s husk and bran. To produce white rice, the bran layer and the germ in  are removed, leaving mostly the starchy endosperm. (Wiki) In the process many vitamins and dietary minerals are lost. But the worst could be the loss of the polyphenols

MND: Are there any risks, indirectly, yes, if the rice grew in a polluted soil.

Two main issues:

  • Cadmium : This study  was concerned with measured Cadmium levels in the soil and brown rice of Taiwan, since such levels have increased in sync with industrial emissions

    1. Ill effects of cadmium are extensive. They include cancer,lung disease, chest pain, see source 3) for more details


  • Arsenic: Arsenic levels are a concern for brown rice grown in the Hainan Island, China. Hence a similar study as the one above. This is to be put in the context a a UNICEF report on arsenic pollution risks for the food supply
    • Arsenic is human carcinogen that has been shown to cause skin, lung, bladder, liver, kidney, and prostate cancer. (Toxtown)
