was passiert wenn man zu viele bananen isst — can a DNA test help?

Eating too many bananas can cause digestive discomfort (bloating, diarrhea) due to high fiber and FODMAPs, and in extreme cases hyperkalemia, but this is rare for healthy individuals. A DNA test is not helpful for this question. While some consumer tests claim to assess carbohydrate digestion (e.g., AMY1 for starch) or potassium metabolism, there is no validated genetic test for banana tolerance. The evidence is weak and largely marketing-driven. If you experience symptoms, focus on your diet and consult a healthcare professional rather than relying on a DNA test.
