I started eating oatmeal because it was a healthy breakfast, even though I would nearly gag at the bland taste and horrible texture. I had to buy flavored types or add tons of fruit to be able to eat it. So glad I got over that one!
Yogurt. It's fine for some, but it messes up my stomach, yet I've tried repeatedly to consume it because it's "healthy" and good for my digestion (despite the stomach cramps??).
Total/Special K cereal. I used these to get all my daily vitamins. Of course, I couldn't stand either unless I sprinkled in sugar and added other things for flavor.
Beans. I don't like beans, but I always saw them as a way to up my vegetable count for the day. Now I'm happy to bypass them.
Whole grains. I've never been big on breads, but when whole-wheat pasta got popular I was all over that!
