was hat kohlenhydrate — what does this mean exactly?

The question 'what are carbohydrates' is fundamental to nutrition science. Carbohydrates are macronutrients found as sugars, starches, and fibers. They serve as the body's primary energy source, especially for the brain and muscles. In the context of MyBody-X's testing services, carbohydrates are relevant in several ways: genetic variants like rs7903146 in TCF7L2 affect blood sugar metabolism and diabetes risk, while APOA2 (rs5082) modulates response to saturated fat, not directly carbs. Gut health tests, such as those for small intestinal bacterial overgrowth (SIBO), rely on carbohydrate fermentation, which can cause bloating and pain. However, the provided context does not contain a formal definition of carbohydrates. The evidence is mechanistic: carbohydrates are enzymatically broken down into glucose, absorbed via insulin-dependent pathways, and excessive intake can contribute to metabolic disorders. Consumers should understand that carbohydrates are not inherently bad; quality, quantity, and individual genetic and microbial factors determine health effects. Direct-to-consumer tests can offer guidance but do not replace professional medical advice.
