Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Rice oil, commonly referred to as rice bran oil, has been studied for its potential cardiovascular benefits, particularly in supporting arterial health. Scientific interest centers on its unique composition: rice bran oil is rich in unsaturated fatty acids, plant sterols, and the antioxidant compound γ-oryzanol. Multiple human and animal studies have found that rice bran oil can help lower total and LDL cholesterol, both of which are established risk factors for atherosclerosis and arterial disease. For example, a randomized controlled trial published in the "American Journal of Clinical Nutrition" (2005) found that replacing other dietary fats with rice bran oil lowered cholesterol in healthy adults. The cholesterol-lowering effect is thought to be due to the combined action of unsaturated fats and plant sterols, which inhibit cholesterol absorption in the intestine.

Additionally, γ-oryzanol, unique to rice bran oil, has demonstrated antioxidant activity that may protect arteries from oxidative stress and inflammation—processes implicated in arterial dysfunction and the development of cardiovascular diseases. While these findings are promising, most clinical trials are relatively small, of short duration, and focus on surrogate markers such as cholesterol rather than direct measures of arterial health or cardiovascular events. Therefore, although the evidence suggests rice bran oil can support arterial health mainly through lipid lowering and antioxidative effects, more large-scale and long-term studies are needed to fully confirm its role.
