Values are per 100g unless noted.
Glycemic Load (GL) is a measure of how much a specific serving of food is likely to raise blood glucose, taking into account both the type of carbohydrate and the amount consumed.
Food values are estimates. Labels and recipes vary by brand and preparation.
Alcohol can lower blood glucose several hours later. Risk of overnight hypoglycemia, especially without food.

This is a simplified estimate from net carbs. Fat, protein, fiber, activity, stress, sleep, meds, and timing can change the real response.

  • Berries (mixed)25–40
  • Apple38
  • Kiwi50
  • Banana (ripe)60
