1. You Get a Healthy Dose of Antioxidants
Antioxidants are important because they bind with and neutralize harmful free radicals in the body. There are many different types of antioxidants, but oatmeal is rich in a type called polyphenols. More specifically, oatmeal contains a kind of polyphenol called avenanthramide, and it is virtually the only food that contains it.
Avenanthramides are thought to bring down blood pressure because they boost production of nitric oxide. Nitric oxide is responsible for dilating blood vessels to improve blood flow. As with most antioxidants, avenanthramides have anti-inflammatory effects, but unusually, they also tend to reduce itchiness.
