Hi, I appreciate your concern for your beloved friend who seems to be suffering from a disorder called Pica. Raw rice contains the same amount of calories and nutrition as do the equivalent quantity of cooked rice. Raw rice lacks the flavor and texture and you should increase fluid intake to hydrate the rice if this is your preferred way to eat rice. Eating raw rice may be due to a disorder called Pica which is characterized by having increased appetite for non-nutritious substances such as clay, chalk, wall paint, tissue paper. It may also result in abnormal appetite for something that may be considered as food ingredients such as flour, raw potato and raw rice. Pica is usually suggestive of some underlying nutritional deficiency due to vitamins or minerals like zinc. Eat contaminated raw rice may result in infections if the rice is not washed.So, in view of the above your friend needs to evaluated for psychological counselling and aversion therapy beside correcting the underlying nutritional deficiencies that might be responsible for her habit. Hope the advice given above would be beneficial to her. Let me know if I can assist you further. A feed back is appreciated. Regards, Dr. Mohammed Taher Ali
