Carbohydrates, along with proteins and fats, are macronutrients. We need to all three in large quantities since they provide energy, aka calories. Carbs can be broken down further into two categories: simple and complex. Both simple and complex carbs turn into glucose (blood sugar) in the body, which our muscles use as fuel. The classification depends on the carbohydrates molecular structure, which affects how the carbs are broken down and absorbed by the body. Complex carbohydrates are made of longer molecule chains than their simple counterparts and therefore take longer for the body to break down and absorb. Simple carbohydrates — found naturally in foods like fruit, milk products, white bread, and table sugar — are broken down and absorbed quickly, causing a sharp rise in your blood sugar levels that can leave you feeling tired and hungry soon after eating them. On the other hand, complex carbohydrates are fibrous and starchy and are found in foods like legumes, starchy vegetables, and whole grains. Complex carbs release glucose more slowly into the bloodstream, offering a steadier source of energy to keep blood sugar levels stable and pesky hunger pangs away.
