Oatmeal is great in that it can be a filling comfort food, but also has a large number of healthy properties to actually make you feel better from the inside out. A complex carbohydrate, eating oatmeal causes your brain to produce higher levels of the feel-good chemical serotonin, helping you to feel calmer and less stressed.
Studies have shown that kids who choose oatmeal for breakfast tend to be much sharper throughout the morning in school compared to kids who had alternative morning meals.
