Sourdough is a fermented dough with a mixture of naturally occurring yeast and lactic acid bacteria. It is made of flour and water. The sourdough bacteria pre-digests the flour, which releases the micronutrients, making it easier to digest and absorb. This process supports the gut microbiome and enhances brain health, by reducing conditions such as anxiety and depression.

Here are some additional Sourdough Facts:

  • Sourdough is the oldest form of leavened (naturally rising) bread – likely from the Egyptians around 1500 BC. 
  • The lactic acid in sourdough bread also boosts orexin levels in the brain. This helps you regulate wakefulness and your appetite.
  • Sourdough is lower on the GI scale than conventional bread as many of the sugars and starches in the flour are broken down and eaten up by the natural yeasts in sourdough.
