Insulin resistance will eventually cause the pancreas to become unable to meet the body's need for insulin. Then glucose will begin to build up in the bloodstream, and type 2 diabetes may be the ultimate result.
The Endocrine Society reports that natural antioxidants can improve insulin resistance. This even holds true of people with metabolic syndrome. Metabolic syndrome involves high blood pressure, elevated insulin, excess fat around the waist and unhealthy cholesterol levels. These factors can increase the risk of diabetes, heart disease and stroke.
Dr. Antonio Mancini was the lead researcher on this study. "Dr. Mancini pointed out that there's evidence oxidative stress, which can result in damage to blood particles and cells, plays a role in the metabolic syndrome. And previous research has shown that antioxidants can prevent oxidative damage to cells and sometimes even repair damage. Antioxidants, which are found naturally in many foods including fruits, vegetables, legumes and nuts, include vitamins E and C, selenium and carotenoids, such as beta-carotene."
