Studies have shown that monounsaturated and polyunsaturated fats may improve blood sugar control in people with diabetes.
Consuming any fat with carbohydrates helps slow the absorption of sugars in the digestive tract and leads to a slower rise in blood sugar. However, monounsaturated and polyunsaturated fats, in particular, may play a bigger role in blood sugar control.
In a review of 102 clinical studies that included 4,220 adults, researchers found that replacing just 5% of saturated fat intake with polyunsaturated fats led to a significant reduction in blood sugar levels and HbA1c, a marker of long-term blood sugar control.
Additionally, replacing saturated fat with polyunsaturated fat significantly improved insulin secretion in these subjects. Insulin helps cells absorb glucose and keeps your blood sugar from getting too high.
Animal studies also suggest that peanut oil improves blood sugar control.
In one study, diabetic rats fed peanut oil experienced significant reductions in both blood sugar levels and HbA1c. In another study, diabetic mice given diets fortified with peanut oil had significant reductions in blood sugar.
Peanut oil may reduce heart disease risk factors. It may also help improve insulin sensitivity and lower blood sugar in people with diabetes. It is also a great source of vitamin E, a powerful antioxidant that protects the body from free radical damage.
