Sourdough Rye Bread

We are often asked: Why does Metabolic Balance recommend sourdough rather than bread containing yeast?

The answer lies in the long fermentation process that happens with sourdough preparation. During this fermentation, the grain is properly broken down and the phytic acid effectively pre-digested. This is important as phytic acid is known to bind to the nutrients and minerals in the grain, thereby preventing us from absorbing them. Also reducing the phytic acid makes the bread lighter, healthier and easier to digest. Rye grains need a good long time to progress to it’s quality and be ready for baking. The sourdough method makes sure this happens naturally while boosting friendly bacteria in the dough which improves the shelf life of the rye bread. It also develops a wonderful taste and the delicious smell of fresh sourdough bread!

When yeast is added to bread dough, these natural processes are enormously accelerated, unfortunately to the detriment of the quality of the bread. This method of added yeast to bread baking makes it much harder for us to digest the bread and can cause digestive problems.
