Rice bran oil is a good source of vitamin E and healthy fats
Rice bran oil is a popular "healthy oil" in Japan, Asia, and India. It is a good source of vitamin E and healthy fats, and has a range of health benefits supported by research.
Vitamin E is a fat-soluble vitamin that is involved in immune function and blood vessel health. It is also a powerful antioxidant that helps protect cells from oxidative stress. Rice bran oil contains 29% of the daily value of vitamin E, as well as other important nutrients such as poly- and mono-unsaturated fats (the "good fats"). These unsaturated fats can improve blood cholesterol levels, reducing the risk of heart disease and type 2 diabetes. The Japanese government even recognizes rice bran oil as a health food due to its cholesterol-lowering effects.
In addition to its health benefits, rice bran oil is also versatile in the kitchen. It has a high smoke point, making it suitable for high-temperature cooking, and its subtle, nutty flavor won't overpower dishes. It is also ideal for frying and baking, and its beneficial compounds are well-preserved when cooked.
When adding rice bran oil to your diet, it is important to use it in moderation and follow the serving suggestions. It should be noted that rice bran oil is a fat and consuming too much of it can cause side effects such as gas and stomach discomfort. If you have a gastrointestinal condition, it is best to avoid rice bran oil as the fiber in it could block your digestive tract. Always consult with your doctor before adding new supplements to your diet.

Studies have shown that consuming these unsaturated fats can improve blood cholesterol levels, which can decrease your risk of heart disease and type 2 diabetes. Substituting rice bran oil for other fats in the diet may be effective in lowering cholesterol, especially for those with high cholesterol.
Rice bran oil contains substances that may decrease the amount of cholesterol absorbed by the body. It has been found to decrease LDL cholesterol by 7% and total cholesterol, without negatively affecting HDL cholesterol. This may be due to the high concentration of vitamin E in rice bran oil.
In addition to its cholesterol-lowering effects, rice bran oil can also help to lower blood pressure, especially when used in combination with antihypertensive medication. The antioxidants and bioactive compounds in rice bran oil may also play a protective role in the pathogenesis of several metabolic ailments, including chronic diseases and inflammation.

Rice bran is high in protein and dietary fibre
Rice bran is a nutrient-rich by-product of the rice milling process. It is a good source of high-quality plant-based protein with a protein content of about 10% to 15%. This protein consists of 37% albumin, 36% globulin, 22% glutelin, and 5% prolamin. Rice bran is also rich in lysine, an essential amino acid.
Rice bran is also a good source of dietary fibre, consisting of almost 27% dietary fibre, including insoluble fibre. The fibre content of rice bran ranges between 12% and 15%, with 90% of this being insoluble fibre, including cellulose, hemicellulose, and arabinoxylans. Pectin and β-glucan, soluble fibres, are present in rice bran but only in trace amounts.
The health benefits of the protein and fibre content in rice bran include antidiabetic, lipid-lowering, hypotensive, antioxidant, and anti-inflammatory effects. Its consumption also improves bowel function.
Rice bran oil is a popular "healthy oil" in Japan, Asia, and India. It is a good source of vitamin E and poly- and mono-unsaturated fats.

It may help improve insulin resistance and lower blood sugar levels
Rice bran is the outer layer of rice grains, and rice bran oil is extracted from it. It is commonly used as a cooking oil in many Asian countries, including Japan, India, and China.
Rice bran and its oil have been found to have several health benefits. They are a good source of vitamin E and poly- and mono-unsaturated fats (the "good fats"). Studies have shown that consuming these unsaturated fats can improve blood cholesterol levels, which can decrease the risk of heart disease and type 2 diabetes.
Rice bran oil may also help lower blood sugar levels and improve insulin resistance. Test-tube studies in mouse cells have shown that rice bran oil reduces insulin resistance by neutralizing free radicals, which are unstable molecules that may lead to oxidative stress. In a 17-day study on mice with type 2 diabetes, rice bran oil significantly lowered blood sugar levels by increasing insulin levels compared to the control group. A human study found similar results, where the morning after consuming a single meal containing 3.7 grams of rice bran mixed in oil, participants' blood sugar levels dropped by 15% compared to those who didn't eat this ingredient.
However, it is important to note that more human studies are needed to confirm these effects on insulin resistance and blood sugar levels. Additionally, rice bran oil is a fat and should be consumed in moderation. It is always recommended to consult with your doctor before adding any new supplement to your diet.
