Best Save
Sourdough bread has the advantage over other breads of keeping longer without changing flavor and texture, especially before slicing. “Whole sourdough bread can be stored for 4 days and 3 days after opening,” says our expert. How to store sourdough bread? Wrapped in a tea towel at room temperature (but it will lose moisture because the water will partially evaporate), in an airtight ziplock bag (however the crust will be less crispy), or frozen. “You can freeze it whole (and in this case take it out the day before) or cut it into slices and put a slice of frozen bread directly into the toaster,” says Marlene Fioro.

Best food quality
Cereals contain a lot of minerals (calcium, magnesium, zinc…) but they also contain phytates, which prevent our body from absorbing them. “The yeast and lactic acid bacteria present in natural sourdough contains the enzyme phytase, which is able to break down phytic acid under the action of fermentation and thus release grain minerals, making them bioavailable,” explains Marlene Fioreau. So fermented sourdough bread has nutritional value!

More digestible
Sourdough bread is also better digested. “Sourdough fermentation is already a kind of digestion. The bread is, as it were, pre-chewed,” says Marlene Fioro. In addition, sourdough bread is often made with whole grain flour, which contains more fiber and therefore makes it easier to transport.

Moderate GI: good for line and health
Another benefit of natural sourdough bread is its lower glycemic index (GI) than other types of bread. “It has been proven that sourdough fermentation can lower the glycemic index of cereal,” says Marlene Fioro. In addition, if you put butter or other fat on a slice of sourdough bread, the glycemic index will drop even more!

Non-allergenic gluten-free bread
You can bake non-allergenic gluten-free bread if you use old wheat or spelled flour. “Bread made from ancient flour and natural sourdough does not cause allergies, it can be eaten by people with gluten intolerance (but not those with celiac disease),” says our expert. Also, thanks to sourdough, you can bake gluten-free bread from flour that does not contain it (rice flour).
