To enhance fiber intake healthily, experts suggest opting for whole-food snacks instead of processed fiber gummies. Seven nutritious snack ideas include chia seed pudding, dark chocolate bark, and avocado toast, all of which provide significant fiber along with essential nutrients. Gastroenterologist Dr. Wendi LeBrett advises against relying on fiber gummies, as isolated fibers can lead to digestive issues like gas and bloating. Aiming for 25 to 38 grams of fiber daily is recommended, with fruits like raspberries and vegetables like quinoa being excellent sources. It's important to drink plenty of water when increasing fiber consumption to avoid constipation. Gradually adding fiber-rich foods throughout the day, such as incorporating fruits at breakfast and whole grains at lunch, can help build a high-fiber diet without discomfort. This approach allows for a balanced intake that supports gut health.
