Rolled oats

We should all be eating more whole grains; they're one of the keys to a healthy diet. And among whole grains, oats are heavy hitters, delivering serious nutrition plus powerful cholesterol-lowering benefits.

The main difference between rolled oats and steel-cut oats is how they're manufactured. Both types begin as whole oats (groats), from which the outer layer (the hull) is stripped, leaving the fiber-rich bran, the endosperm, and the germ, which is home to vitamins and minerals, antioxidants, and healthy oils. From there, the oats are either rolled or steel-cut.
