Rice bran is a by-product of the rice milling process, derived from the outer layer of rice. It is the outer layer of brown rice that is separated during milling. This layer contains the nutrients necessary for the rice to sprout, therefore rice bran solubles are the most concentrated and easily absorbable form of nutrients derived from rice, and do not contain the carbohydrate content from the white part of the rice grain.
What are the health benefits?
High in antioxidants
Rice bran oil has been found to contain the phytochemical γ-oryzanol, which has antioxidant properties. Antioxidant compounds can eliminate free radicals in the body that can lead to the development of chronic diseases. Rice bran oil may also be beneficial for weight loss due to its content of oleic acid and linoleic acid, which can aid in weight management. Vitamin E, which is present in rice bran oil, may also have a positive impact on brain function and endocrine hormone balance. However, further research is needed to fully understand the antioxidant potential of rice bran oil.
Phytosterols are a group of plant-derived compounds found in rice bran that have a structural similarity to cholesterol in the human body. These compounds are known to have cholesterol-lowering effects and may also have anti-inflammatory properties. Rice bran is particularly rich in beta-sitosterol, a phytosterol that has been shown to effectively reduce blood cholesterol levels and lower the risk of heart disease.
Rice bran oil has been found to potentially possess blood sugar-lowering properties. A study suggested that using rice bran oil together with sesame oil as cooking oil may help to reduce plasma glucose levels in individuals with type 2 diabetes. This anti-diabetic effect of rice bran oil may be attributed to its high content of γ-oryzanol, which can promote insulin production and regulate blood glucose levels by activating liver enzymes that lower blood glucose levels.
Safety of using rice bran:
Please be aware of certain medications, including thyroid hormone replacement therapy and some antibiotics. If you are taking medication regularly, it is recommended that you consult with your healthcare provider before using rice bran or any other new supplement or food.
