Insulin not only moves glucose into the cells, but it also escorts Vitamin C. Blood sugar hogs the seats on the bus in most diabetics, therefore reducing the amount of Vitamin C we can absorb. This is the premise of The GAA Theory: high glucose levels hinder vitamin C entry into cells.

Vitamin C is vitally important for many functions throughout the body - a big one being metabolism. Glucose and Vitamin C are similar in the way they enter the cells. Both molecules require help from insulin. The name for the process that brings glucose and Vitamin C through cell membranes is insulin-mediated uptake. The insulin-mediated uptake of glucose and vitamin C uses white blood cells. White blood cells have more insulin pumps and they may contain 20 times the amount of vitamin C as ordinary cells.

So does increasing your Vitamin C help boost your glycemic control? Diabetes Health cited a study that confirms daily doses of 2,000 mg of absorbic acid improved both fasting blood glucose and HbA1c readings in patients with type 2 diabetes. Next time you swing by the store - see if some Emergen-C can help you achieve better glycemic control. With 1,000 mg of Vitamin C per packet - their homepage says: Feel The Good. Little did they know how good it could be for Type 2 diabetics!

Central obesity is associated with insulin resistance through factors that are not fully understood. Researchers studied the effects of three different diets on body fat distribution, insulin sensitivity and peripheral adiponectin gene expression.

Adiponectin is secreted from fat tissue into the blood. The presence of adiponectin can result in improved insulin sensitivity and glucose tolerance, and can assist in mobilizing sugar out of the blood The hormone plays a role in the suppression of the metabolic derangements that may result in type 2 diabetes, obesity, atherosclerosis and non-alcoholic fatty liver disease.

The study involved 11 volunteers who were the offspring of obese type 2 diabetic patients with noticeable abdominal fat deposits. The volunteers were considered insulin resistant and they maintained average hemoglobin A1c levels of greater than 6.5% without medication. All subjects underwent three dietary periods of 28 days each in a crossover design: a) diet enriched in saturated fat (SAT), b) diet rich in monounsaturated fat (MUFA; Mediterranean diet) and c) diet rich in carbohydrates (CHO). Weight, body composition and resting energy expenditure remained unchanged during the three dietary periods. However, when patients were fed a CHO-enriched diet their fat mass was redistributed towards their abdominal region and their periphery fat accumulation decreased compared with a diet MUFA-rich and high SAT diets. Changes in fat deposition were associated with decreased levels of adiponectin after meals and lower insulin sensitivity.

The results of this study conclude a diet rich in monounsaturated fat prevents central fat redistribution and a decrease in after meal adiponectin levels. These findings support the belief that a carbohydrate-rich diet in insulin-resistant subjects exacerbates the insulin resistance. The moral of the story is: to enhance insulin sensitivity - look for a diet rich in monounsaturated fats and less dense in carbohydrates. Chances are if you've tinkered around with your food pyramid - you already knew the results of this study.
