You have probably heard me recommend sourdough bread over every other bread out there (personal opinion, backed up by some solid evidence). However, did you know that almost all popular branded sourdough bread is FAKE! Yep, it's not sourdough like we expect. It will not offer the same benefit as sourdough bread made with a sourdough starter. In my Classroom under "Best Buys" I posted a paper on how to buy sourdough bread, assuring that it is truly beneficial and not just vinegar flavored white bread. Check it out then look at the sourdough bread you may have at home or the next time you're at the store. My guess is you have fake bread. Best bet is buying sourdough from a bakery but I have found some "real" sourdough in the stores. It is more expensive and totally worth the extra expense.
