Eating large meals, especially those that contain a lot of carbohydrates, typically result in after-meal blood glucose readings that are elevated. Ideally, diabetics want after-meal blood glucose readings to be less than 180mg/dL. Oftentimes, Massey has people monitor blood glucose before and then two hours after a meal to evaluate how their food choices are impacting blood glucose levels.
“Typically, we are looking for no more than a 40- to 50-point increase, so if the blood glucose is 120 before a meal and 250 after a meal, that 130-point difference indicates that the meal was too high in carbohydrates,” says Massey. Talk to your doctor about how to create a diabetes-friendly meal plan that’s best for your health.
