was sind komplexe kohlenhydrate — what can you do yourself?

Complex carbohydrates are long-chain sugars (polysaccharides) such as starch and dietary fiber found in whole grains, legumes, and vegetables. They are digested more slowly than simple sugars, leading to a steadier blood glucose rise and better satiety. What you can do yourself: Replace refined grains with whole-grain alternatives, eat legumes (lentils, beans) regularly, and include oats, quinoa, or sweet potatoes in your meals. Preparation matters – cooling cooked potatoes or pasta increases resistant starch, which benefits gut health. The evidence for these dietary recommendations is strong (mechanistic and observational), but there is no personalized DNA-based guidance for complex carbohydrates. Direct postprandial blood glucose monitoring can help assess individual tolerance. Be cautious with highly processed 'whole-grain' products – they often contain added sugars. The German Nutrition Society recommends at least 30 g of fiber per day – a practical target.
