Choosing foods with a low glycaemic index (GI) is helpful as they don't raise glucose levels in the blood as quickly as high glycaemic index foods. Basmati rice is lower GI than other types of rice, sweet potato is lower GI than ordinary potato, new potatoes are lower than baked potatoes. Eating protein at the same time as carbohydrate helps as it lowers the overall glycaemic index of the meal.
