I didn't know either that oatmeal has probiotics. Does the instant oatmeal also has probiotics ?
In my honest opinion, I would say yes. Instant oatmeal is just more quicker to cook and has added sugar in there. In addition to that: the oatmeal is precooked as well, I think it has the same benefits as regular oatmeal. I actually noticed instant oatmeal has a lot more added vitamins/protein in there as well; that is a bonus lol.
I personally use fresh/regular oatmeal since its cheaper
Here is a statment from the USDA: In fact, in the USDA nutrient database, instant oatmeal possesses the same nutritional profile as regular or quick-cooking oatmeal
