Raw, Cooked, Rolled, Steel-Cut, or Whole Oat Groats. It doesn’t matter how you eat them, just eat them! Oats help to reduce cholesterol, reduce inflammation and have the ability to act as a little “street cleaner” in the digestive tract.
Whole Oat Groats
A groat is another name for a grain kernel. Whole oat groats are the result of simply harvesting oats, cleaning them, and removing their inedible hulls. You can most often find these in health food stores. They take the longest to cook.
Steel Cut Oats
If you cut groats into two or three pieces with a sharp metal blade, you get steel cut oats. They cook quicker than oat groats, because water can more easily penetrate the smaller pieces. Steel cut oats are also sometimes called Irish oatmeal.
Scottish Oatmeal
Instead of cutting oats with a steel blade, the Scots traditionally stone-grind them, creating broken bits of varying sizes, which some say results in a creamier porridge than steel-cutting.
Rolled Oats – regular (old fashioned)
Rolled oats (sometimes called old fashioned oats) are created when oat groats are steamed and then rolled into flakes. This process stabilizes the healthy oils in the oats, so they stay fresh longer, and helps the oats cook faster, by creating a greater surface area.
Rolled Oats – quick or instant
If you roll the oat flakes thinner, and/or steam them longer, you create quick oats and ultimately instant oats. The nutrition stays the same (these are all whole grains) but the texture changes – a plus for some people and a drawback for others. The good thing about having so many choices is that everyone can get exactly the taste they like best!
