Oats and oat bran are whole-grain foods that have been widely studied for their health-promoting properties, largely attributed to their high content of beta-glucan, a soluble fiber. Research suggests that regular consumption of beta-glucan from oats may help support healthy cholesterol levels, with enough evidence that several regulatory bodies have approved qualified health claims in this area. Studies also indicate that the soluble fiber in oats can slow the digestion of carbohydrates, potentially contributing to more stable blood sugar responses after meals. Beyond internal health, colloidal oatmeal has a long history of use in skin care, with research supporting its role in soothing irritation and maintaining the skin barrier. Available as steel-cut oats, rolled oats, oat bran, and oat flour, they offer a versatile and accessible addition to everyday meals.
