Walnuts contain very small amounts of carbohydrates (3.3g per 100g of product) and have a low glycaemic index (GI) as a result (typically between 0 and 24). This means that they are broken down slowly and release glucose into the bloodstream in a more gradual manner, which is particularly helpful to people with Type 2 diabetes. The glycaemic load for walnuts is also very low (typically 0-1).
