Bloating and poor digestion are common issues that often go unnoticed until they become severe. Dr. Saurabh Sethi, a Harvard-trained gastroenterologist, emphasizes the importance of gut health, which plays a crucial role in immunity and overall wellness. He recommends five powerful foods to improve digestion: First, replace refined white bread with whole-grain sourdough, which supports beneficial gut bacteria through natural fermentation. Second, opt for plain kefir, Greek yogurt, or traditional dahi instead of sugary yogurts to nourish the gut microbiome. Third, choose slightly green bananas, which contain more resistant starch that acts as a prebiotic. Fourth, swap diet sodas for sparkling water with lemon, as artificial sweeteners can disrupt gut health. Lastly, avoid processed deli meats in favor of grilled or baked proteins to reduce inflammation and promote digestive wellness. These simple dietary changes can lead to significant improvements in gut health.
