Sesame Oil and Bran Oil Combo May Help Improve Lipid Profiles of Diabetics

A recent study suggests that using a 20% cold-pressed sesame oil and 80% physically refined rice bran oil as cooking oil may help lower hyperglycemia and improve the lipid profiles of people with type 2 diabetes.


Participants in the study included 400 people, 300 of whom were newly diagnosed with type 2 diabetes. The other 100 participants were normoglycemic, which means they had the normal amount of glucose in their blood. All of the participants were required to have no evidence of cardiovascular or liver disease, no usage of anti-diabetic or cholesterol-lowering medication, and no adherence to a specific diet.


The participants were separated into four groups: normoglycemic subjects with the oil blend; type 2 diabetics with the oil blend; type 2 diabetics with 5 mg daily of the anti-diabetic drug Glibenclamide; and type 2 diabetics with the oil blend and Glibenclamide. The oil was distributed at two-week intervals for a maximum of four to five liters and all of the participants were told to use it for eight weeks. The researchers recommended that participants use between 35 and 40 mL per day.


At the conclusion of the study, the researchers noted no changes in body weight, weight to height ratio, or body mass index in the diabetes patients. However, at week 4 and week 8 the type 2 diabetes patients who consumed the sesame oil blend showed significant reductions in fasting and postprandial blood glucose. No reductions were seen in the the normoglycemic participants.


The researchers also noted significantly lower levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol in the diabetic group that consumed the oil blend.


Researchers from Fukoka University in Japan, Adani Wilmer Limited in India, Sultan Qaboos University in Oman, the Indian Council of Medical Research, and Prof. M.M. Poly Hospital in India conducted the study. It was published online ahead of print on April 1, 2016, in the American Journal of Medicine.


Previous studies have linked sesame oil with lower blood sugar, reduced blood pressure in diabetics and healthier looking skin. Bran oil has been associated with easing hot flashes in menopausal women and is also found in some skin creams.
