Eight Foods That Become Healthier When Chilled in the Fridge

2. Oats: Overnight Nutritional Powerhouse

Like rice, oats also benefit from being cooled. Overnight oats—made by soaking raw oats in milk or plant-based milk and left in the fridge overnight—are not only convenient, but also nutritionally superior in many ways. As the oats absorb the liquid and cool, resistant starch forms, improving the digestive profile of this hearty grain. These starches feed the good bacteria in your gut, supporting a healthy microbiome. Additionally, oats are naturally rich in beta-glucan, a soluble fiber known to reduce cholesterol levels and improve heart health. By simply preparing your breakfast the night before, you’re enhancing its ability to support long-term wellness.
