Intolerance to certain components of milk, gluten and histamine, is a condition that affects more than 40% of the European population. This intolerance is closely linked to GENETICS, among other factors. FOODgenes evaluates genetic variants related to our body's ability to process certain nutrients or compounds present in food, such as lactose, gluten or histamine. The objective of this profile is to determine or rule out the predisposition to suffer from any pathology related to gluten, lactose and histamine intolerance, based on the GENETICS of each person.
