Many think that as carbohydrate sweet potatoes are a forbidden fruit so to speak for a diabetic. Nothing could be further from the truth. Plus it has so many unique nutritional benefits to offer in every single bite.

Diabetes
Sweet potatoes are abundant in adiponectin. According to the National Institutes of Health, adiponectin is a very specific protein type hormone that plays a large role in the development of insulin resistance. It normally circulates in high concentrations in the average weight population however the amount is lower in individual’s that are obese. During research adiponectin levels were reduced prior to the development of type 2 diabetes, and administration of this protein has been effective in lowering plasma glucose levels as well as increasing insulin sensitivity. The way it is thought to produce this effect it through an increase in fatty acid oxidation and inhibition of glucose production in the liver. This may eventually lead to a potential treatment for metabolic syndrome and type 2 diabetes. In the meantime eat more sweet potatoes!
