When you think of blood sugar (aka glucose) levels, does your mind jump straight to how much sugar you eat? If so, that’s completely fair. Your carb intake does play a significant role in your blood sugar levels. Carbs (no matter if it’s fruit, grains, or candy) are eventually broken down and metabolized into glucose. Eating a lot of carbs, especially foods with added sugar and no fiber, floods the bloodstream with glucose and can cause a dramatic increase in blood sugar.
