Soluble fiber dissolves in water, forming a gel-like substance that helps regulate blood sugar levels, lower cholesterol, and promote feelings of fullness.

The podcast episodes 'Fiber has tons of benefits. Here's how to eat more of it' and 'Why Fibre Isn't A Fad' explore the differences between soluble and insoluble fiber, their respective benefits, and strategies for increasing fiber intake through a variety of plant-based foods.
