Guilty, LOL! I am a huge fan of banana bread, however I don't make it often because I try to don't eat sugar and flour at home.
And I have never tried to make sourdough, my husband tried it a couple of times in the past, but the results were not always as expected. I have in my mind the idea that is not so easy to make it, so I'll look forward to seeing your post dedicated to that exclusively. I agree, that sourdough bread reduces a lot the undesired consequences of eating bread, and at least for me, it does not cause inflammation at all.
Your banana bread looks so yummy. Perfect to go with the coffee that I'm going to prepare right now, but without banana bread to go with :( hehe.
