How to consume high-fiber foods

Fiber is one of the most important nutrients that plays a vital role in digestive health. It helps in controlling blood sugar levels and keeps you full for longer, which supports weight management and prevents overeating. It is also linked to heart health, as soluble fiber helps lower LDL (bad) cholesterol and supports better blood circulation. Furthermore, it is said that regular fiber intake promotes a healthy gut microbiome, which boosts immunity and nutrient absorption. Addressing the importance of fiber Dr. Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford universities, recently shared a post on Instagram, where he recommended 8 high-fiber foods and the right way of consuming them.
