A study published in the Journal of Nutritional Biochemistry found that consuming rice bran oil for 4 weeks reduced total cholesterol by 7% and LDL cholesterol by 7.9% in hypercholesterolemic individuals (Berger et al., 2005). This cholesterol-lowering effect is attributed to the oil’s high content of oryzanol, a mixture of ferulic acid esters of sterols and triterpene alcohols.
Moreover, the oil’s balanced ratio of saturated, monounsaturated, and polyunsaturated fatty acids contributes to its heart-healthy profile. A 2016 meta-analysis in the Journal of Clinical Lipidology reported that replacing 1% of dietary saturated fat with rice bran oil could potentially reduce cardiovascular disease risk by 2.7% (Huth et al., 2019).
2. Antioxidant Properties
Rice bran oil is packed with potent antioxidants, primarily γ-oryzanol, tocotrienols, and tocopherols.
Research indicates that rice bran oil contains up to 1.6% γ-oryzanol, which is significantly higher than other vegetable oils (Pestana et al., 2008). This compound has been shown to have strong antioxidant properties, potentially protecting cells from oxidative stress.
A study in the Journal of Agricultural and Food Chemistry found that the antioxidant activity of rice bran oil was comparable to, and in some cases higher than, that of green tea and other vegetable oils (Iqbal et al., 2005). This high antioxidant capacity may contribute to the oil’s potential anti-inflammatory and anti-cancer properties.
3. Blood Sugar Regulation
Emerging research suggests that rice bran oil may have beneficial effects on blood sugar control, making it potentially useful for individuals with or at risk of diabetes.
A study published in the Journal of Nutritional Biochemistry reported that diabetic rats fed rice bran oil showed a 30% reduction in blood glucose levels compared to control groups (Chen & Cheng, 2012). The researchers attributed this effect to the oil’s high content of γ-oryzanol and tocotrienols.
In human studies, consumption of rice bran oil was associated with a 15% improvement in insulin sensitivity in overweight individuals with type 2 diabetes (Devarajan et al., 2017). While more research is needed, these findings suggest that rice bran oil may be a beneficial addition to a diabetes-friendly diet.
4. Skin Health Enhancement
The nutrient profile of rice bran oil makes it potentially beneficial for skin health when used both topically and in the diet.
Rice bran oil contains squalene, a compound that makes up about 12% of human sebum, making it an excellent natural moisturizer (Patel & Naik, 2004). This property, combined with its high vitamin E content, may contribute to improved skin hydration and elasticity.
A study in the Journal of Cosmetic Dermatology found that a cream containing 2% rice bran extract improved skin roughness by 14% and skin elasticity by 6% after 28 days of use (Manosroi et al., 2012). While this study used rice bran extract, many of the beneficial compounds are present in the oil as well.
5. Cancer-Fighting Potential
While more research is needed, preliminary studies suggest rice bran oil may have anticancer properties.
The oil’s high content of γ-oryzanol and tocotrienols has been the focus of cancer research. In vitro studies have shown that these compounds can inhibit the proliferation of various cancer cell lines, including those of breast, lung, and liver cancer (Henderson et al., 2012).
A particularly interesting study published in BMC Complementary and Alternative Medicine found that rice bran oil extract induced apoptosis (programmed cell death) in human colorectal cancer cells, with up to 84% cell death observed at higher concentrations (Forster et al., 2013). While these results are promising, it’s important to note that more human studies are needed to confirm these potential anticancer effects.

Rice bran oil’s effect on weight loss is complex and not fully understood. A study published in the Journal of Nutritional Biochemistry (Shimoda et al., 2015) found that mice fed a high-fat diet supplemented with rice bran oil gained less weight than those on a regular high-fat diet. The rice bran oil group showed a 16% reduction in body weight gain compared to the control group.
However, human studies are limited and have shown mixed results. A small human trial in the Journal of Clinical Biochemistry and Nutrition (Nagao et al., 2013) found that subjects consuming rice bran oil as part of a calorie-restricted diet lost an average of 4.5% body weight over 12 weeks, but this was not significantly different from the control group.
Rice Bran Oil in low-calorie diets
While rice bran oil is calorie-dense (about 120 calories per tablespoon), its nutrient profile may make it valuable in low-calorie diets when used judiciously. A study in the European Journal of Nutrition (Berger et al., 2005) found that incorporating rice bran oil into a low-calorie diet improved lipid profiles more than the same diet with olive oil. Participants in the rice bran oil group showed a 7.7% decrease in LDL cholesterol compared to a 2.8% decrease in the olive oil group. This suggests that including small amounts of rice bran oil in a calorie-restricted diet could enhance its health benefits without compromising weight loss goals.
Rice Bran Oil and satiety
Rice bran oil may contribute to increased satiety due to its fat content and unique compounds. A study in the Journal of Food Science and Technology (Karupaiah et al., 2011) found that meals containing rice bran oil increased post-meal fullness compared to meals with palm oil. Participants reported feeling 15% fuller 2 hours after the rice bran oil meal. The researchers attributed this effect to rice bran oil’s higher content of unsaturated fats and bioactive compounds like γ-oryzanol. However, more research is needed to confirm these satiety effects and their potential impact on long-term weight management.
Rice Bran Oil and Metabolism
Some studies suggest that rice bran oil might influence metabolism. A study in the Journal of Nutritional Biochemistry (Chou et al., 2009) found that rats fed rice bran oil showed increased expression of genes related to fat metabolism in the liver. The rice bran oil group had a 23% higher expression of CPT-1, a key enzyme in fatty acid oxidation. In human studies, the γ-oryzanol in rice bran oil has been shown to potentially enhance fat oxidation.
A study in Nutrition Journal (Resuehr et al., 2014) reported that a single dose of γ-oryzanol increased fat oxidation by 13.7% in healthy adults during moderate-intensity exercise. While these results are promising, more research is needed to fully understand the metabolic effects of rice bran oil in humans and its potential role in weight management.
Rice Bran Oil for Health Conditions
While weight management is important, do rice bran oils have an effect in more serious health conditions? Here’s what the scientific literature has to say:
Rice Bran Oil and Diabetes
Rice bran oil shows promise in managing diabetes.

The rice bran oil group showed a 30% reduction in fasting blood glucose levels compared to the control group. Furthermore, a human study in the Journal of Food Science and Technology (Lai et al., 2012) reported that consuming rice bran oil for 4 weeks led to a 14% decrease in HbA1c levels in type 2 diabetic patients. The γ-oryzanol and tocotrienols in rice bran oil are thought to be responsible for these anti-diabetic effects.
Rice Bran Oil and Heart Health
Research on rice bran oil’s impact on cardiovascular health is particularly promising. A meta-analysis published in the Journal of Clinical Lipidology (Jolfaie et al., 2016) analyzed multiple studies and concluded that rice bran oil consumption significantly improved lipid profiles. The analysis found that rice bran oil intake was associated with a 7.2% reduction in total cholesterol and a 7.4% reduction in LDL cholesterol. Moreover, a study in the American Journal of Medicine (Kuriyan et al., 2005) showed that replacing cooking oil with rice bran oil for 3 months resulted in a 9% increase in HDL cholesterol in patients with hyperlipidemia. These effects are attributed to the oil’s balanced fatty acid profile and unique phytosterol content.
Rice Bran Oil and digestive issues
Rice bran oil may have beneficial effects on digestive health. A study in the World Journal of Gastroenterology (Kataoka et al., 2012) found that rice bran oil supplementation improved symptoms in patients with irritable bowel syndrome (IBS). Participants reported a 41% reduction in abdominal pain and discomfort after 4 weeks of rice bran oil consumption. Additionally, research published in the Journal of Nutritional Science and Vitaminology (Tamura et al., 2012) showed that rice bran oil increased the production of short-chain fatty acids in the gut by 27%, potentially promoting a healthier gut microbiome.
Rice Bran Oil and inflammation
The anti-inflammatory properties of rice bran oil have been the subject of several studies. Research published in Lipids in Health and Disease (Rao et al., 2016) found that rice bran oil supplementation reduced markers of inflammation in individuals with metabolic syndrome. The study reported a 20% decrease in C-reactive protein levels after 12 weeks of rice bran oil consumption. Furthermore, a study in the Journal of Agricultural and Food Chemistry (Islam et al., 2008) demonstrated that the γ-oryzanol in rice bran oil inhibited the production of pro-inflammatory cytokines by up to 35% in cell culture experiments.
Rice Bran Oil and cancer prevention
While more research is needed, some studies suggest potential anti-cancer properties of rice bran oil components. A review in the European Journal of Cancer Prevention (Henderson et al., 2012) highlighted the potential of rice bran bioactive compounds in cancer prevention. In vitro studies have shown that tocotrienols from rice bran oil can inhibit the growth of breast cancer cells by up to 50%. Additionally, a study in the journal Molecules (Arab et al., 2013) found that γ-oryzanol from rice bran oil-induced apoptosis in human colorectal cancer cells, with up to 60% cell death observed at higher concentrations. However, it’s important to note that these are primarily laboratory studies, and more human research is needed to confirm any cancer-preventive effects.
The evidence from these studies suggests that rice bran oil may have potential benefits for various health conditions, but more research, particularly human studies, is needed in many areas. Here’s a summary of the current evidence:
