A US-based gastroenterologist, Dr. Joseph Salhab, recommends several foods for improved gut health in 2026. These include watermelon, lime, broccoli, and sourdough bread, which are rich in fiber and probiotics. These foods nourish beneficial gut bacteria, aid digestion, prevent constipation, and may reduce the risk of diseases like colon cancer. Dr. Salhab highlights their antioxidant and anti-inflammatory properties, calling them 'nature's multivitamin' for their overall health benefits.
