Blood sugar angle

Dark chocolate has 46 g of carbohydrate per 100 g (24 g sugars, 11 g fiber); Milk chocolate has 59 g (52 g sugars, 3.4 g fiber). This table is not a measured glycemic-response comparison; the amount eaten and the rest of the meal matter. Glycemic index values vary by variety, ripeness and cooking, so treat any single number with caution — and eat either with vegetables and some protein.
