Hi again Abeybaby,
Yes, oats are carbohydrates (as are all breakfast cereals like wheat, barley, rice, rye, corn). While all carbos affect our blood sugar (even folks like you without diabetes), "whole grain" carbos are easier on our systems and don't typically cause spikes in blood sugar, because they have fiber to slow the digestion process.
Your blood sugars after eating sound normal to me.
