was sind komplexe kohlenhydrate — which blood markers matter?

Complex carbohydrates are long-chain sugars (polysaccharides) found in whole grains, legumes, vegetables, and oats. They are digested more slowly than simple sugars, leading to a more gradual blood glucose rise and providing fiber. Which blood markers matter? Fasting glucose and HbA1c reflect long-term blood sugar control. Fasting triglycerides tend to be lower with a low-sugar, high-fiber diet, while a favorable HDL/LDL ratio indicates good carbohydrate quality. The HOMA index (insulin resistance) can also improve. Important: No single marker tells the whole story. The evidence for the benefits of complex carbohydrates is strong (human-strong), based on large cohort studies and dietary guidelines. Caveat: Blood markers are snapshots; overall diet quality and physical activity are key. No specific sources from the given context.
