Dr. Karan Rajan, a surgeon and health content creator from the UK, emphasizes the gut health benefits of stewed apples, calling them a 'cheat code' for digestive wellness. He explains that cooking apples unlocks their fiber content, making it more accessible for gut bacteria while reducing the risk of bloating. The heat breaks down complex pectin chains in raw apples into smaller fragments that ferment evenly in the colon, leading to less gas production. Additionally, stewing lowers the levels of FODMAPs, fermentable sugars that can cause gastrointestinal distress in sensitive individuals. To maximize health benefits, Dr. Rajan advises keeping the apple skin on during cooking to retain polyphenols, the antioxidants found in apples. He also notes that other fruits, such as pears, plums, and berries, can similarly benefit from gentle cooking, and suggests adding cinnamon to enhance microbial diversity. This information serves as a guide for those interested in improving their gut health through dietary choices.
