Stuhlprobe: which diet helps?

A stool sample (microbiome test) can provide insights into your gut bacteria composition. Evidence suggests that a fiber-rich diet with prebiotics (e.g., oats, flaxseeds, vegetables) and fermented foods (e.g., sauerkraut, kimchi) supports microbial diversity and may aid digestion and weight management. However, the evidence for personalized diets based solely on stool tests is still limited—most recommendations rely on general dietary principles. The test can serve as a guide but should not replace medical advice. Especially for children or those with health conditions, dietary changes should be discussed with a doctor or dietitian. The effects of specific bacterial strains are often individual and not always reproducible. Bottom line: stool testing is a useful tool, but not a prescription for a specific diet.
