Our data do not confirm, on an objective basis, the differences in expected symptoms resulting from wheat and spelt products, suggesting a strong nocebo effect for wheat and a placebo effect for spelt. Neither signs of inflammation nor markers for intestinal barrier integrity were influenced. The +FODMAP bread was better tolerated than both T breads (p = 0.003 for spelt p = 0.068 for wheat) and equally well tolerated as both C breads and +Gluten breads after normalization to the washout scores. The main outcome parameter was the Irritable Bowel Syndrome-Severity Scoring System, which was higher than self-estimated by the participants after spelt bread consumption (p = 0.002 for T p = 0.028 for C) and lower for wheat bread (p = 0.052 for T p = 0.007 for C), resulting in no difference between wheat and spelt bread tolerance.

Study breads comprised spelt and wheat breads made either after a traditional (T) or a current (C) recipe, resulting in four bread types plus a gluten-free bread with 1.5% added oligosaccharides (+FODMAP) and a gluten-free bread with 5% added wheat gluten (+Gluten). Twenty-four adults with a history of NCWS but suspected spelt tolerance were challenged in a single-blinded crossover design over six weeks with six different study breads each at 300 g per day for 4 days followed by a washout phase of 3 days. Therefore, we performed blinded wheat and spelt bread challenge in this patient group. This experience has neither been validated nor explained on a molecular level. spelta) compared to wheat (Triticum aestivum ssp. Individuals with suspected non-celiac wheat sensitivity (NCWS) often report better tolerance of spelt (Triticum aestivum ssp. Legal and societal aspects regarding the (non) GMO status of gene-edited plants, gluten-free food production chain management, and food labelling will be discussed. An efficient screening pipeline to detect and select promising coeliac-safe(r) wheat lines will be described. CRISPR/Cas9 enables now to produce wheat line that potentially have a strongly reduced coeliac-immunogenicity, as will be explained from two model studies. The large number of gluten genes in wheat’s complex genome hinder conventional breeding to produce a coeliac-safe wheat while maintaining good baking properties, although low gluten levels can be reached. Some specific digestion-stable fragments of wheat gluten are recognized by immune cells that become inflammatory in the small intestine, ultimately resulting in a variety of severe symptoms. Wheat-based foods and food with wheat ingredients can provoke coeliac disease in genetically predisposed susceptible individuals representing 1–2% of the population. Bread wheat developed from that time into the commodity crop that it is nowadays. Early wheat cultivation in fields surrounded by wild relatives facilitated the occurrence of interspecific hybridizations one of the resulting hybrids was bread wheat, with superior nutritional and food-technological qualities, largely due to the favourable composition of the gluten proteins in the grain.
During preceding eras, humans gradually acquired the necessary knowledge and tools for processing and cultivation of cereals, making themselves unconsciously prepared to become the first farmers when climate improved at the end of the last Ice Age, some 12 thousand years ago, in the Near East (Fertile Crescent) region. Cereal consumption by humans is older than agriculture.
