Possibly Effective for...
- High cholesterol, when added to a reduced-fat diet. Following a low-fat diet and taking 85 grams of full-fat rice bran per day seems to lower total cholesterol by 8% and "bad" low-density lipoprotein (LDL) cholesterol by 14%. Rice bran does not seem to affect other blood fats such as triglycerides or "good" high-density lipoprotein (HDL) cholesterol. Taking 11.8 grams of rice bran in a reduced-fat form doesn't work as well. Both full-fat and reduced-fat rice bran work about as well as oat bran for reducing high cholesterol.
Rice bran oil also seems to be effective for high cholesterol. There is some evidence that rice bran oil can reduce total cholesterol by 14%, LDL by 20%, triglycerides by 20%, and increase HDL by 41%.
