Oats contain beta-glucan, a soluble fiber that has been shown to help lower cholesterol levels by forming a gel-like substance in the gut, which binds to cholesterol and helps excrete it from the body.

Overnight oats are pre-soaked in liquid, which starts the process of digestion even before you consume them, making nutrients more bioavailable and easier for the body to absorb.
