Whole oats are full of good-for-you fiber, high in protein, and contain vitamins and minerals like folate, iron, and magnesium. I buy my whole rolled oats in the bulk section at my local grocery store, but if your store doesn’t have a bulk section you’ll probably be able to find them in the baking aisle. Regardless, be sure you are buying 100% pure whole rolled oats, nothing that says “instant” or “quick cooking.”
