We’ve all been told that oatmeal and other fiber rich foods lower cholesterol, but do you know why?
It turns out that the bile in our stomachs is composed of 70% cholesterol. Since our bodies are very efficient machines we usually recycle that bile and use it again. However, when you eat oatmeal, the water soluble fiber attaches to the bile and it is excreted instead of recycled. To replace the bile that is lost your body has to pull cholesterol from your blood. And voila! Lower cholesterol.
I find that surprisingly cool.
