9 Factors That Affect How Insulin Works
What are you eating?
Food won’t change the rate at which insulin is absorbed into the blood, but it does affect your blood sugar in general.
Fatty foods are absorbed slowly, and your insulin may start to wear off before the food is absorbed.
Carbohydrate-rich foods like white rice or white bread that have a higher glycemic index are absorbed faster and may affect your blood sugar more quickly.
