Sourdough or regular bread: fermented loaf wins over health-conscious eaters
Sourdough is a special kind of bread made with just flour, water, salt, and a natural starter.
The starter ferments for a long time, which gives sourdough its tangy taste.
During fermentation, wild yeast and helpful bacteria change the dough.
This process partly breaks down gluten, protein, and other parts of the bread.
Because of this, sourdough can be easier for our tummies to digest.
It also helps our bodies use healthy minerals like iron and zinc better.
Sourdough does not make our blood sugar rise as quickly as regular white bread.
Many people feel less bloated when they eat it.
But experts say sourdough is not a magic food.
You still need to eat the right amount, especially if you have diabetes, and check how much salt is in the bread.
Sourdough is made with flour, water, salt and a natural starter that ferments over several days, using wild yeast and beneficial bacteria instead of commercial yeast or preservatives.
Fermentation lowers sourdough's glycaemic index, helping to prevent blood sugar spikes and making it a better option for people managing diabetes or insulin resistance.
The slow fermentation reduces phytic acid, improving the body's absorption of minerals such as iron, zinc, magnesium and selenium.
Sourdough typically ferments for 12 to 48 hours compared with 1 to 2 hours for regular bread, and many people find it easier to digest with less bloating.
Experts caution that sourdough is not a miracle food: portion control and salt content still matter, and whole-grain options are recommended.
