was sind leere kohlenhydrate — can a microbiome test help?

The question about 'empty carbohydrates' (simple sugars, refined grains) and whether a microbiome test can help is not directly addressed in the provided context. Microbiome tests can profile gut bacteria, but their ability to guide decisions about empty carbs is not evidence-based. The context includes a mention of butyrate producers in children, but that is about prebiotics, not empty carbs. Empty carbs lack fiber and nutrients; a microbiome test might indicate low diversity or low butyrate producers, but this is speculative. Current evidence for consumer microbiome tests in dietary guidance is weak (mechanistic at best). Without specific context, the answer must be conservative: microbiome tests cannot reliably tell you about empty carb intake or its effects. Evidence: unclear.
