A diet enriched with antioxidant nutrients can help to improve insulin resistance in adults with metabolic syndrome. Individuals with metabolic syndrome exhibit increased some or all of the following: waist circumference, blood pressure, fasting glucose and triglycerides, and a reduction in high density lipoprotein (HDL) cholesterol. They have a reduced ability to utilize insulin, and are at an increased risk of developing cardiovascular disease and diabetes.
Subjects participating in the study were all placed on 1,500 calorie per diets for 3 months, but only a subgroup were provided with fruits and vegetables high in antioxidants. All lost weight, but only those who received the antioxidant-enriched diet had significant reductions in insulin resistance. The antioxidants were thought to have helped reduce oxidative stress, which may help protect against a number of conditions, including metabolic syndrome.
