Thanks for the replies. I asked because I was looking for an alternative to cereals. All the bran cereals are hard and crunchy, and just a few bites make me feel full all day long. I don't feel like eating the rest of the day, and I can usually taste the bran all day. (Not only does it stick to my tongue and stomach, but it stays in my teeth all day even after brushing and flossing.) However, I do fine with 100% whole wheat breads and even bran muffins, at least with my upper GI system. I'm wondering though if the 100% whole wheat bread I'm eating almost daily could be contributing to worse bloating and intestinal gas.
