(SNP48)","description":"This is a Premium-exclusive episode of the podcast. To listen to the full episode you need to be subscribed to Sigma Nutrition Premium. This episode examines dietary fiber through the lens of a practical, clinically relevant question: if higher fiber intakes are consistently associated with reduced chronic disease risk, what intake level should we be aiming for to meaningfully improve health outcomes? The discussion deliberately spans from common online claims that fiber is \u201cnot essential\u201d (and therefore unnecessary), through to mechanistic reasoning and the highest-quality evidence we have for hard outcomes and accepted intermediate cardiometabolic endpoints. Across the episode, we\u2019ll hear from six expert perspectives to integrate epidemiology, controlled feeding studies, and clinical guideline contexts. We will consider how the dose\u2013response patterns, fiber type\/source, individual tolerance, and the limitations of nutrition trials all influence what can be recommended with confidence.
