I’ve always liked waffles. Who doesn’t!?

Then I traveled to Belgium and figured I’d reached waffle heaven. Once you’ve had crispy, chewy, yeasty Belgian waffles there’s no going back. I thought Belgian waffles were the pinnacle of waffle perfection!

But I was still willing to try another kind of waffles.  I wanted to use some of my sourdough starter, but didn’t feel like making bread.  I love the health benefits of sourdough, so I figured I’d try sourdough waffles and see how I liked it.  How could I not like waffles?

Little did I know I was about to step into the best waffle eating experience of my life….

Health Benefits

This article has a great summary on the health benefits of sourdough bread.  Check it out for all the references but here’s the TLDR version:

  • The lactic acid bacteria cultured from sourdough starter breaks down most of the gluten in wheat flour. Although it’s still not recommended for people with Celiac to run out and buy sourdough bread, this is a promising area of research for Celiacs. This is good news for people with gluten intolerance, who may be able to handle a small amount of gluten.
  • The sourdough bacteria are able to breakdown phytic acid found in whole grains. Phytic acid binds to minerals, rendering them useless for absorption by the body. So sourdough bread gives us more minerals to absorb such as iron, magnesium, and zinc!
  • Acrylamide, a carcinogenic compound, is formed when the amino acid asparagine is dry heated with other nutrients. This happens in the crust of bread or when bread is toasted. Sourdough bacteria reduce the amount of asparagine, thus reducing acrylamide production!
  • Sourdough bread has the lowest effect on raising blood sugar. In this study, subjects who ate sourdough bread for breakfast saw improved blood sugar control after lunch and even hours after lunch!
