Historically, rice is considered a sign of good fortune and prosperity in many cultures. And the oil extract from rice bran has countless applications. So, read the entire article to discover what life-changing benefits rice bran oil can bring.
What is Rice Bran Oil?
Rice bran oil, as the name suggests, is derived from rice. Rice has several layers, one of which is called the “Bran.” It is a brown coloured, hard and oily layer between the rice kernel and the outer husk. The rice bran oil comes from the bran.
Primarily, rice bran oil is edible because it is not sticky, making it a suitable cooking medium. Moreover, the appropriate amount of fats in a balanced proportion makes this oil healthy for the heart. Also, its 15-20% less absorption and economical price make it an ideal edible oil.
Rice Bran Oil is an excellent source of a powerful antioxidant, Oryzanol.
A study claims that this antioxidant assists in reducing cardiovascular diseases. The oil is flavourful and has a high smoking point. It means that the oil retains its nutrition even at high temperatures, making rice bran oil meet all criteria that define a healthy edible oil for all of us. Not just this, you can use rice bran oil for nourishing, cleansing and brightening your skin.
Types of Rice Bran Oil
Refined oil is purified to remove suspended particles, colour, odour, flavour component or any toxic substance. It is purified using chemicals. After purification, clear and pure oil is left behind, which you can use for various purposes.
An elaborate manufacturing process is involved here. Excessive filtration and the chemicals involved make the refined oil utterly devoid of any kind of taste or smell. The process also strips the oils’ vitamin E, minerals and beta carotene, making it less nutritious.
As a result, fewer beta carotene and vitamin E reduce the shelf life. Therefore, manufacturers add synthetic products to increase the shelf life. These synthetic products are BHA and BHT. Dieticians recommend avoiding these ingredients because they can be harmful enough to cause cancer.
The process includes filtering out the suspended particles. The technique used to extract the oil is the traditional cold pressing method with no processing except for filtering and bottling it.
It helps retain the flavour of the seeds. This kind of oil may retain flavour to the extent that it might as well overpower the natural flavour of the food you cook it with.

Rice Bran Oil Extraction
People in various parts of the world, mostly in tropical and subtropical regions, cultivate rice. Rice flourishes when soil is heavy, high in humus and clay, with temperatures ranging from 20-40 degrees Celsius. Paddy is a grain that contains one rice kernel, and it also has several layers. The first layer is called Husk. Right under the husk lies “Bran.” The bran contains over 75% of the oil content of the grain. It is rich in fat and vitamin complexes.
The oil is ultimately derived when bran goes through Expeller Pressing and Solvent Extraction processes. First, bran is placed in the expeller, where the barrel’s inner screw presses it until it releases the oil. It leaves a bran cake as a leftover. Next, people extract any remaining oil in the bran cake using Hexane, a food-grade solvent. The extracted oil then goes through filtering and neutralisation until it is ready for consumption.
Top Health Benefits of Rice Bran Oil
Oriza Sativa or Rice Bran oil is rich in vitamins, minerals and essential oils. The presence of Oryzanol in rice bran oil makes it a healthy food option and also makes it suitable for use in skincare formulations.
The other advantages include its abundance in vitamin E, moisturising, hair and skin protection. Let’s take a closer look at the top health benefits in detail.
Improves Cholesterol, Blood Sugar Levels and Blood Pressure
Oryzanol (a natural antioxidant) reduces the absorption of serum (bad) cholesterol like LDL or VLDL. Rice bran oil contains Oryzanol in appropriate quantities. It is low in saturated fats, which leads to improvement in blood cholesterol levels.
A high blood pressure research report by researchers at American Heart Association in 2012 highlights the role of rice bran oil in reducing blood pressure. The report suggests that people who consume rice bran oil as cooking oil observed a significant drop in cholesterol and blood sugar levels.
According to a study, monounsaturated and poly-unsaturated fats or good fats effectively lower cholesterol levels. Rice bran oil contains the appropriate proportion of these fats. Hence, it helps lower cholesterol levels in your body.
Consuming rice bran oil with sesame oil or any hypertensive medication helps reduce blood pressure significantly. According to a study, systolic and diastolic blood pressures drop on the consumption of rice bran oil.
Maintains a Healthy Heart
Consuming fatty acids in the right proportions is highly beneficial. Rice bran oil increases cholesterol elimination and decreases cholesterol absorption. It promotes overall cardiovascular health. A study claims that rice bran oil leads to a reduction in overall cholesterol levels which is beneficial for the heart.
Neutral Taste and High Smoking Point
Rice bran oil has a high smoking point. That means it is suitable for cooking in high temperatures. It does not lose its nutrition even in excessive heat or excessively high temperatures. Also, RBO is less viscous, which ensures that it does not stick to food. Interestingly the absorption of rice bran oil is way less than other oils.
Another quality that makes it an appropriate choice for cooking is its mild flavour with a neutral taste. It is versatile and extremely light. These attributes make rice bran oil one of the best cooking oils for good health.
Oil Pulling is a technique that requires swishing and pulling the oil through teeth. When you use rice bran oil in this oil pulling technique, it proves to be quite beneficial. It effectively reduces bad breath or halitosis, giving you excellent oral health.

Reduces Post-Menopause Symptoms
Rice bran oil improves overall strength in menopausal women and reduces the symptoms related to menopause. These symptoms include hot flashes and other irritations. Also, it prevents the production of luteinising hormone, responsible for making sudden changes in hormone levels. As a result, it helps get rid of the symptoms. Y-oryzanol in RBO also helps manage hot flashes.
Enhances Vitamin E Levels
Any byproduct of cellular metabolism can turn out to be dangerous. For example, it may cause healthy cells to mutate and then turn into cancerous cells. Rice bran oil boasts 29% of the daily value for vitamin E.
Vitamin E includes tocopherol and tocotrienol. They function as antioxidants and behave as free radicals. These antioxidants neutralise these byproducts and reduce the chance of cancer. Vitamin E aids in the healing of wounds, reduces wrinkles, protects from sunburn and increases cell regeneration.
- Rice bran oil is an excellent supplement to regulate thyroid functioning. It lowers the thyroid-stimulating hormone levels (TSH) in people suffering from hyperthyroidism. In addition, it influences the working of the hypothalamus. As a result, it prevents any kind of dysfunction.
- Rice bran oil also helps increase muscle mass due to gamma-oryzanol. The gamma-oryzanol increases endorphin levels in the body that aids in muscle development.
