Health benefits associated with eating oatmeal include reducing LDL cholesterol levels and treating or preventing weight gain, high blood pressure and type 2 diabetes, according to WebMD. Oatmeal is also rich in fiber, which helps to regulate blood sugar levels, eases constipation and makes the stomach feel fuller so that people don't eat as much food throughout the day.
In addition to reducing LDL, or bad, cholesterol levels, oatmeal may also improve the LDL cholesterol profile by keeping small LDL particles at bay, according to WebMD. This is beneficial because small LDL particles may be even more harmful than large ones. Oatmeal contains antioxidants that may help to reduce inflammation, but the amount that would need to be consumed to notice the benefits is very large. However, eating oatmeal may still provide anti-inflammatory benefits over time.
As part of a low cholesterol and saturated fat diet, the soluble fiber in whole oats may reduce the risk of heart disease, notes WebMD. In order to reap the health benefits associated with oatmeal, it is important to eat the right type. Many types of instant oatmeal contains substantial amounts of sodium and sugar, and they should be avoided. Healthy oatmeal consists of steel-cut oats or plain rolled oats cooked in a small amount of water or milk. Wholesome foods such as fruits are a healthy addition to oatmeal.
