Health benefits of rice bran oil.
Although scientific evidence is relatively limited, rice bran oil (RBO) is tenaciously believed to be a healthy vegetable oil in Asian countries. It exerts hypocholesterolemic activity in relation to more commonly used vegetable oils and is characterized by a relatively high content of non-fatty acid components, some of which are known to have beneficial health effects. Components specific for RBO such as gamma-oryzanol and tocotrienols could participate in its hypocholesterolemic effects. In addition, blending RBO with safflower oil, but not with sunflower oil, may magnify the hypocholesterolemic efficacy. This observation is of particular interest with regard to dietary intervention with RBO. The possible mechanism underlying this effect may at least in part be related to the specific triglyceride structure of safflower oil, differing from that of sunflower oil.
