The truth is that all oatmeal contains the same amazing beta glucan which can help manage weight, cholesterol, and blood pressure.  However, one must be aware that instant oatmeal packages and regular oatmeal are two different animals.  According to Donna Feldman, MS, RD  flavored instant oatmeal contains added sweeteners which means more calories.  Also, a serving size in a packet of instant oatmeal contains less oats than the 1/2 cup dry oats serving size listed on a can of regular oatmeal.  Less oatmeal = less fiber and beta glucan.  However, in general, all oatmeal is good heart-healthy oatmeal.
