Taylor Swift’s interest in sourdough bread has renewed attention on its potential health benefits, with nutrition experts saying science supports part of its healthy reputation—but with important caveats.
Details
- Research reviews suggest that naturally fermented sourdough may cause a slower rise in blood sugar compared with some conventional breads, while the fermentation process can also reduce compounds that interfere with absorption of minerals such as iron, zinc, and magnesium.
- It may also be easier for some people to digest because fermentation lowers certain compounds linked to bloating and digestive discomfort.
- However, nutrition experts stress that these benefits are not guaranteed in every product, as results vary depending on the type of flour used, fermentation length, and manufacturing process. Some studies show little difference between sourdough and conventional bread.
What’s Next?
To maximize potential benefits, experts recommend choosing naturally fermented sourdough made with whole grains rather than fast-produced or heavily processed commercial varieties.
