Rolled/Oats Rolled oats are oat
groats that have been rolled into flat flakes under heavy rollers. The
oat, like some other
cereals, has a hard, inedible outer
hull that must be removed before the grain can be eaten. After the hulls have been removed from the
bran-covered oat grains, the remainder is called
oat groats. Oat groats can be used as cereal, but since the bran layer makes the grains tough to chew and contains an
enzyme that can cause the oats to go
rancid, oat groats are usually steam-treated to soften them and denature the enzymes. It can be argued that this process removes the enzyme
phytase which would otherwise serve to break down the the high-
phytate content of commercial oats which inhibits the absorption of iron by the human body.
Steel-cut oats are oat groats that have been chopped into smaller pieces and retain bits of the bran layer.
