High glycemic carbohydrates have been found to be inversely related to Parkinson's Disease. Carbohydrates that have a high glycemic index (such as sugar, white bread, baked potatoes and breakfast cereals) are those that break down quickly in to glucose in the blood. For more information go to Glycemic index.

The researchers expected that foods such as these would decrease the risk of Parkinson's Disease by an insulin-induced increase in brain dopamine. Their theory appears to be correct, because high glycemic carbohydrates were significantly inversely associated with the risk of Parkinson's Disease. The greater the intake, the less was the risk. No association was observed for other dietary carbohydrates, or dietary fiber intake. It was already known that an inability to make use of carbohydrates was common in Parkinson's Disease, with 50%-80% of people with Parkinson's Disease being prone to diabetes. In those people, higher carbohydrate intakes can not be made use of. For more information see the Complete abstract. For more current news go to Parkinson's Disease News.
