Oatmeal (Rolled Oats) Overview

Oatmeal made from rolled oats is a popular breakfast grain. While oats contain fiber and can be more blood-sugar-friendly than many sugary cereals, oatmeal is still high in carbohydrates and is not suitable for keto or strict low-carb eating. For diabetic-friendly plans, small portions paired with protein and fat may be workable depending on individual response.
