Note that the nutritional label for the instant oatmeal indicates it contains 3 grams of dietary fiber per serving of which 1 gram is SF and therefore it contains 2 grams of IF. The instant oatmeal contains twice as much IF compared to SF.
In comparison Old Fashion Quaker oats contains 4 gram of dietary fiber per serving of which 2 grams is SF and 2 grams is IF. There are equal amounts of SF and IF.
There is no question that bran has been added to change the IF to SF ratio in the instant oatmeal. And my GI track can really tell the difference
