Fuel Up Right: The Underrated Power of Complex Carbs
April 01, 2025
Complex carbohydrates are longer chains of sugars linked together, and because they take longer to break down compared to simple carbohydrates, they provide a steady release of energy. Complex carbs digest slowly, giving you long-lasting fuel, perfect for workouts, busy schedules, and staying focused.
Simple carbs are one or two sugars linked together that are digested and enter the bloodstream quickly. Simple sugars are lower in nutritional value and high in empty calories, which can negatively impact blood sugar levels and weight management. When creating a healthy diet, consuming more complex carbohydrates for fiber, vitamins, minerals, and overall nutrient density is best. It is also beneficial to be mindful when choosing simple carbs to keep sugar intake in check. One can find simple carbs in nutritious foods like fruit and dairy. Still, they are usually in lower amounts and provide more nutrition than foods high in cane sugar and high fructose corn syrup.
Here is an overview of the benefits of complex carbohydrates and how to include them in a healthy diet:
- Sustained and Steady Energy: Complex carbs digest slowly, giving you the fuel you need for exercise and even completing your daily activities.
- Rich in Fiber: Complex carbs are an excellent source of both soluble and insoluble fiber, which supports digestion, helps maintain blood sugar levels, and manages cholesterol.
- Gut Health: Complex carbs help support a healthy microbiome because they contain fibers humans cannot digest, but gut bacteria can. The bacteria ferment them and produce short-chain fatty acids (SCFA). SCFAs strengthen the gut lining, reduce inflammation, and support the immune system.
- Loaded with Vitamins and Minerals: Complex carbs provide B vitamins, iron, magnesium, and antioxidants. These nutrients can help prevent chronic disease.
- Support Muscle Recovery and Growth: Complex carbs are essential for replenishing and sustaining glycogen stores before and after workouts. When combined with protein, they can improve protein absorption. In the absence of carbohydrate intake, glycogen stores become depleted, resulting in fatigue and decreased performance.
- Weight Management: Fiber found in complex carbohydrates can aid in weight management by helping you feel more satisfied and maintaining balanced blood sugar levels.
Ensure you include a variety of complex carbohydrates in your diet, such as whole grains (brown rice, whole wheat bread, quinoa, whole wheat pasta), legumes (black beans, kidney beans, lentils, navy beans, chickpeas, edamame), starchy vegetables (sweet potatoes, white potatoes, corn, green peas), and fruits (bananas, berries, apples, pears, melon). When consuming simple sugars, opt for unrefined options like honey, maple syrup, and agave. However, use them sparingly and limit added sugars to 5-10% of your total daily calories. Another guideline is to aim for about 25-50 grams (6-12 teaspoons) per day, depending on your caloric intake.
