Following our first article, this article will discuss the benefits of Oryzanol the way it is discussed by world’s leading medical research centers.
Helps in lowering cholesterol
A scientific study conducted by Tufts University, Boston and University of Massachusetts Lowell, USA has revealed that Oryzanol significantly helps in lowering down bad cholesterol and increasing good cholesterol at the same time.

Anti-Diabetic effect
A Study conducted by Kyungpook National University, Republic of Korea illustrated protective effect of Oryzanol and ferulic acid on high fat diet induced hyperglycemia via regulation of insulin Secretion and hepatic glucose regulating enzyme activities.

Protective Effect on Liver
Studies conducted by Nagasaki university, Japan suggests that y-Oryzanol is very effective against liver cirrhosis, cirrhosis is scarring of the liver and poor liver function. It is the final phase of chronic liver disease. Studies have attributed this to the effective antioxidant property of Oryzanol.

Anti – Carcinogenic Effect
Department of Clinical Sciences, Colorado University has suggested the use of Rice Bran Bio Active components in prevention of several types of cancers, such as breast, liver, lungs and colorectal cancer. Rice bran bioactive components protect against tissue damage through the scavenging of free radicals and the blocking of chronic inflammatory responses.

Effective in treatment of gastrointestinal disorders including stress induced gastric and duodenal ulcers
A Study in Japan found out that an 8-day treatment with gamma-Oryzanol, showed a significant inhibition of fasting ulcer and a 10-day treatment with the same dose of gamma-oyzanol in acetic acid ulcers lowered the serum level of gastrin.

Another Study in Japan reported that the Oryzanol is effective against the stress induced ulcers.

Skin
Oryzanol has been found to have many skin related benefits. The use of Oryzanol in sunscreen products, hair conditioners and moisturizing creams is on the increase in the United States.
A study in Chiang Mai University,Thailand has found Oryzanol as a potential cosmetic raw- material. According to the study Oryzanol helps in skin whitening, skin hydration and is anti ageing. Oryzanol may help to maintain skin function by improvement of skin microcirculation, protection against lipid peroxidation and direct stimulation of sebaceous gland function

A Study by Natural Product Research and Development Center , Chiang Mai University Thailand has again confirmed skin hydration effect of Oryzanol.

Oryzanol due to its antioxidant property is an effective Sunscreen and thus protects the skin from U-V Rays.
Anti Oxidant Effects
Free radicals are the natural by-products of many oxidative metabolic processes within cells. These free radicals can cause damage to cell walls, certain cell structures and genetic material within the cells. Oryzanol found in rice bran oil is also a potent antioxidant. One test-tube study found that Oryzanol was more than four times as effective at stopping tissue oxidation as vitamin E.
A Natural Steroid, testosterone Booster, helps in building lean muscles
A study by Bucci, L., Stiles, J., Sparks, W., and DeLuca,D., compared anabolic steroid users to those athletes supplemented with gamma Oryzanol. Initially, the anabolic steroid users showed greater gains in girth measurements, but by 16 weeks, the gamma Oryzanol users exhibited greater girth measurement increases that all steroid users, without ANY side effects! And the dose for gamma Oryzanol is low.
The antioxidant property of Oryzanol is believed to be responsible for this favourable effect. Very preliminary evidence suggests that γ- Oryzanol may increase endorphin release (a feel good hormone) and aid muscle development.
These findings have created an interest in using γ-Oryzanol as a sports supplement, companies in U.S are selling Oryzanol based Health Supplements for Body building.
Calcium Absorption
Rice bran might help lower cholesterol because the oil it contains has substances that might decrease cholesterol absorption and increase cholesterol elimination. One of the substances in rice bran might decrease calcium absorption; this might help reduce the formation of certain types of kidney stones.
Conclusion on Rice Bran Oil
Rice Bran Oil is the healthiest oil according to the recommended most fatty acid levels by Indian Council of Medical Research.
The National Institute of Nutrition and The Indian Council of Medical Research recommend oils that have an equal proportion of saturated fatty acids, monounsaturated fats and polyunsaturated fats. Rice bran oil has an almost balanced fatty acid composition that is close to this ratio. Rice bran oil is rich in monounsaturated and polyunsaturated fats and free of trans-fats.
A human clinical study was conducted by scientists of National Institute of Nutrition, Indian Council of Medical Research to prove hypolipidemic effect of RBO. They studied this on 12 hyperlipidemic patients, Subjects were told to replace their usual oil (any oil used previously) with Rice Bran oil. A significant decrease in bad cholesterol was noticed after period of 15 days in all 12.
National Institute of Nutrition (The Apex body of Nutrition in India) in its Dietary guidelines for year 2011 has mentioned that Oryzanol found in Rice Bran Oil is helpful in reducing cholesterol and oxidative damage due to ageing, inflammation which occur in chronic diseases.
