Fruits and vegetables are crucial for building a healthy gut.

Dr. Nieman writes that a diverse, fibre-rich diet of fruits, vegetables, legumes and fermented foods supports a healthy gut microbiome, and that antibiotics and processed foods can disrupt that bacterial balance.

The article explains that modern medical understanding of the gastrointestinal tract has expanded beyond digestion to include immune and microbiome functions. It notes that terms such as dysbiosis, leaky gut and the gut–brain axis are now more widely recognized in mainstream medicine. The piece links imbalances in gut bacteria to inflammatory processes and a range of conditions in both children and adults. It highlights dietary patterns and early-life exposures as influential in shaping the gut microbiome. Key facts: - Dysbiosis is described as an imbalance of bowel bacteria and is associated with inflammation and conditions including eczema, asthma, allergic rhinitis, functional abdominal pain, constipation, diarrhea, reflux, obesity and diabetes. - Antibiotics are noted as common disruptors of the gut microbiome; the article stresses that inappropriate frequent use is problematic while acknowledging antibiotics are life-saving when needed. - The article reports that dietary fibre and prebiotics (for example, legumes) and fermented foods such as yogurt, kefir and sauerkraut have been shown to be more efficient than probiotic supplements in supporting the microbiome. - Early-life factors discussed include mode of birth, breastfeeding practices and early introduction to a variety of fruits and vegetables, all of which can influence bacterial colonization and taste development. - Other influences mentioned are stress, chemical contaminants and microplastics in food, and disruptions to circadian rhythm. Summary: The article frames food choices and early-life exposures as central to the development and maintenance of a healthy gut microbiome and links dysbiosis to chronic inflammation and several common health conditions.
