This is where the topic gets more nuanced, and where most flour brands stop talking rather than explain properly.
Non-coeliac gluten sensitivity is different from coeliac disease. It is a real and increasingly recognised condition, but the mechanisms behind it are still being researched, and it is not fully understood why some people react to wheat without testing positive for coeliac disease or a wheat allergy.
Some people with gluten sensitivity report finding stoneground and traditionally fermented wheat products, particularly long-fermented sourdough, easier to digest than flour from heavily refined, quickly processed commercial bread. There are a few possible reasons that get discussed in this space:
● Stoneground flour retains more of the wheat's natural bran, germ, and enzymes, which some people find behaves differently in digestion compared to highly refined flour.
● Long, slow fermentation, such as a traditional sourdough process, gives natural enzymes and wild yeast more time to partially break down gluten proteins and the fermentable carbohydrates known as FODMAPs before the bread is baked, which some research suggests may reduce digestive discomfort for certain people.
● Less processed flour typically has fewer added enzymes, conditioners, and other additives found in some mass-produced commercial bread, which some sensitive individuals report reacting to separately from gluten itself.
We think it is important to be honest that this is an area where the science is still developing, individual responses vary considerably, and what works for one person will not necessarily work for another. This is personal experience and emerging research, not a guarantee.
