Gut microbiome diversity linked to lifestyle and diet

Medical research is increasingly focusing on the human gut microbiome, which can contain between 150 and 450 different bacterial strains depending on an individual's lifestyle. Experts suggest that a diverse microbiome is a central factor for general well-being.

To support microbial diversity, nutritional specialists recommend a varied, plant-based diet and a daily intake of at least 30 grams of dietary fiber. Conversely, factors such as stress, lack of social contact, excessive hygiene, and low-fiber diets can weaken the microbiome.

Recent discussions have highlighted the role of resistant starch, which can be produced by cooling cooked foods like potatoes or pasta for 12 to 24 hours. While this process converts approximately 10 percent of starch into a form usable by gut bacteria and slightly reduces calorie content, experts from the German Society for Gastroenterology, Digestive and Metabolic Diseases (DGVS) note that consuming resistant starch alone is not expected to lead to significant weight loss.
