I haven't gotten myself tested for wheat allergies but I suspect I have them. Along with various prepackaged foods containing gluten, many breads cause fairly severe joint and muscle pains - arthritic reaction, basically. This bread seems to be an exception! I even ran a test. After eating a few slices a day of this bread without any ill effects (working through the whole loaf in less than a week), I tried a sourdough bread from Trader Joe's, also without baker's yeast but with "starter" listed as an ingredient. 2 pieces resulted in 10 hours of arthritic reaction. Back to Alfaro's extra-sourdough.... no reaction, even after several pieces in one day.
Also, it tastes great.
This bread is probably not for everyone who is sensitive to wheat, but it works for me.
