Sourdough bread has seen a serious rise in popularity — and not just for its tangy flavour and satisfying chew. More and more people are reaching for sourdough because it’s thought to be better for you than many other types of bread. But what exactly makes sourdough a healthier option?
Let’s break it down.
It’s All About Fermentation
Sourdough is made through a natural fermentation process using wild yeasts and lactic acid bacteria. This slow fermentation not only gives sourdough its distinctive taste but also helps break down gluten and phytic acid, making the bread easier to digest. For many, this means less bloating and a gentler experience for the gut.
Lower Glycemic Index
Sourdough has a lower glycemic index (GI) than most other breads. This means it causes a slower rise in blood sugar levels, helping to avoid spikes and crashes — good news for anyone keeping an eye on their energy levels or blood sugar.
A study published in the Journal of Nutrition found that sourdough fermentation can improve insulin response, making it a smart choice for those managing type 2 diabetes or trying to avoid it.
Nutrient Availability
Because of the natural leavening process, sourdough bread contains more bioavailable nutrients — meaning your body can actually absorb more of the good stuff. This includes minerals like magnesium, zinc, and iron, which are often locked away in other breads by antinutrients like phytic acid.
Packed with Flavour — and Options
One of the best things about sourdough? It’s delicious — and comes in a variety of options to suit every taste and lifestyle.

For something denser and full of earthy flavour, try our Sourdough Rye Bread — great with smoked salmon, avocado, or a generous swipe of cultured butter.
No Additives, Just Real Food
Our sourdough loaves are made the old-fashioned way: slow-fermented over 24 hours with no additives or preservatives. That means real bread, with real benefits — and none of the ultra-processed extras.
