Whole Grain Oats: are the entire kernel of oat. For ﻿example﻿, rolled oats (steamed and pressed by a roller﻿)﻿ and steel cut oats (cut by steel blade 2-3 times) make up the entire groat. Fun fact, groat comes from the Scottish word describing an oat kernel after it has been hulled!

Oat Bran: Consists of only the oat bran which is the outer layer under the hull/shell.
