The preference for raw rice is related to micronutrient deficiencies and parasitic infections. Some people have micronutrient deficiencies, which can lead to xenophagia, and some people will eat strange foods. Among the micronutrient deficiencies, the most common one is iron deficiency, which can be improved by supplementing with ferrous sulfate, which is associated with anemia, in addition to a preference for raw rice. Some of them are caused by parasitic infections in the body. When there is a parasitic infection in the intestinal system, it will cause a preference for certain foods and a preference for raw rice will be shown. A routine fecal examination should be performed to check for the presence of eggs in the feces, and those found to have parasites should be promptly treated with medication to de-worm the body and avoid eating unclean food in the future.
