In the study, twenty participants with common digestive issues (IBS) were put on two different diets for six weeks each:
Modern wheat products (for example wheat bread)
Identical products but made from an ancient variety of wheat, that hasn’t undergone modern plant breeding.
The participants didn’t know which one of the diets they were put on, and the order in which they were assigned to a diet was randomized. Not even the researchers themselves knew which person ate which diet during the period (a double-blind study). Thus, this is a high quality study, a randomized, double-blind crossover trial, where potential differences should be caused by wheat itself, and not be caused by imagination or expectations.
The difference was clear-cut. When participants with digestive issues consumed modern wheat they felt like they usually did, they suffered from their usual digestive issues. But when for six weeks they ate the ancient wheat their symptoms improved with significantly less abdominal pain, less abdominal bloating and an improved quality of life.
