Steel-cut oats are like regular oatmeal but cut with steel.
Also, not really.
Okay, so they might be cut with steel, but that’s not why they’re called “steel-cut” oats.
Steel-cut oats are actually whole oat groats that have been cut into two or three pieces. What’s a “groat,” you ask? The whole hull of an oat. So, steel-cut oats differ from rolled or old-fashioned oats simply in that they are not pressed into a round shape.
In a side-by-side comparison of steel-cut oats to rolled oats, steel-cut oats have 20 fewer calories per 1/4 cup, but they are completely equal in protein and carbohydrates. Steel-cut oats have no sugar, compared to 1 gram for rolled oats. They have identical amounts of fat, calcium and iron.
The point of steel-cut oats, really, is that they are less-processed. However, to get the health benefits, be sure to buy them without all the sugary mix-ins like flavorings and sweeteners.
