Frequently Asked Questions
Complex carbohydrates are long chains of sugar molecules found in whole, unprocessed foods like grains, legumes, vegetables, and fruits. Unlike simple carbs, they digest slowly, providing sustained energy and stable blood sugar levels.
Due to their slow rate of breakdown in the body, complex carbohydrates deliver glucose into the bloodstream gradually. By providing longer-lasting fuel for your body and brain, this gradual release helps prevent energy dips and surges.
Yes, in most cases. Complex carbs come with fiber, vitamins, and minerals, while simple carbs (like candy and soda) are quickly digested and offer little nutritional value, often leading to energy crashes.
Yes. Eating fiber-rich complex carbs can increase satiety and support portion control. They also help regulate blood sugar, which can prevent cravings and support a healthy metabolism.
Swap refined grains for whole grains (e.g., brown rice instead of white), snack on fruits or air-popped popcorn, and include legumes or sweet potatoes in your meals.
