As a byproduct of rice milling, rice bran is usually used as animal feed or discarded as waste. Yet, it has recently gained attention for its potential health benefits as an oil. Similarly to other nontropical vegetable oils like canola and olive oil, rice bran oil contains higher proportions of heart-healthy unsaturated fat than saturated fat. It also boasts 29% of the Daily Value (DV) for vitamin E, a fat-soluble vitamin involved in immune function and blood vessel health (1, 2). Other compounds in rice bran oil, such as tocotrienols, oryzanol, and plant sterols, have been studied for their health benefits (3). Rice bran oil may support healthy blood sugar levels by improving insulin resistance, a risk factor for type 2 diabetes (4). Insulin lowers blood sugar by transporting sugar into your cells. Yet, if you develop insulin resistance, your body stops responding to this hormone. In a test-tube study in mouse cells, rice bran oil reduced insulin resistance by neutralizing free radicals, which are unstable molecules that may lead to oxidative stress (5). In a 17-day study in mice with type 2 diabetes, rice bran oil significantly lowered blood sugar levels by increasing insuli...
