Sin duda alguna, el Reglamento de ejecución (UE) nº 828/2014 de la Comisión regula una materia muy sensible pues afecta a los celíacos, que padecen una intolerancia permanente al gluten: se ha demostrado científicamente que el trigo (es decir, todas las especies "Triticum", tales como el trigo duro, la espelta y el trigo khorasan), el centeno y la cebada contienen gluten y el gluten de estos cereales puede provocar efectos adversos para la salud en las personas intolerantes al gluten, que, por lo tanto, deben evitar consumirlo.

There is no doubt that Commission Implementing Regulation No 828/2014 regulates a very sensitive area of concern – that of people with coeliac disease who suffer from a permanent intolerance to gluten. Wheat (i.e. all "Triticum" species, such as durum wheat, spelt, and khorasan wheat), rye and barley have been identified as grains that are scientifically reported to contain gluten, and the gluten present in those grains can cause adverse health effects to people intolerant to gluten and therefore its consumption should be avoided by such people.
