What it is
Whole oats are real, minimally-processed grain — and one of the gentler ones, with no gluten and a famously soluble fiber.
Why your biology objects
Oats carry beta-glucan, a soluble fiber that genuinely blunts the glucose spike and binds cholesterol — the rare grain whose fiber earns its reputation. They still hold phytic acid, so soaking helps, and they're a frequent costume for sugary recipes. Check what's listed around them.
