Carbohydrates

Understanding Sugars, Starches, and Their Effects

Carbohydrates are one of three main macronutrients, broken down into glucose (sugar) in your digestive system. They range from simple sugars to complex starches and fiber, but all digestible carbs eventually become glucose in your bloodstream—the difference is mainly in how quickly. While carbohydrates provide quick energy, they also trigger insulin release and can cause blood sugar spikes, especially problematic for people with diabetes or insulin resistance. Understanding how different carbohydrates affect your blood sugar helps you make informed choices about which ones to include, limit, or avoid in your diet.
