Rolled Oats Overview

Rolled oats are steamed and flattened oat groats commonly used for oatmeal, baking, and granola. While oats have more fiber than refined grains, they are still high in carbohydrates and can raise blood sugar in typical servings. Rolled oats are not keto-friendly and are usually not diabetic-friendly in standard portions. Low-carb alternatives include chia pudding, flax-based “oatmeal,” or hemp hearts.
