I know that white flour is not very good for you, so have tried to use whole wheat flour in place of white flour for quite a while.
This can take some getting used to as some whole wheat flours make thinks a little more coarse and grainy.
I was experiencing some abdominal discomfort and took an online quiz to see if I might be allergic to wheat products. My results showed that I might have some intolerance to wheat, so thought I would try a gluten free diet for awhile.
I found out that maize flour would be a good substitute. I have tried it, but I must say, I really miss the taste of the whole wheat flour. I have used other grains that don't have gluten in them that I prefer over maize.
