Maria Godoy connects everyday fiber choices to the gut microbes that help shape immunity and heart health.
The brief
Maria Godoy joins Marielle Segarra to make the case that fiber does far more than support digestion: it can lower cholesterol and regulate blood sugar.
The central mechanism is the gut microbiome, where fiber feeds microbes involved in immunity, heart health and systemic inflammation.
Godoy explains how much fiber people need, distinguishes soluble from insoluble fiber, and points to berries and legumes as practical sources.
The episode favors whole foods over supplements, while stressing a gradual increase so the digestive system can adjust without excessive gas or bloating.
