Celiac disease is one autoimmune disease Unleashed by gluten, a protein complex contained in many foods and drinks such as pasta, pizza, bread and beer. In addition to having to pay attention to any contamination in the kitchen, according to recent searches some celiacs would also be afraid of getting in touch with gluten by kissing a non -celiac partner. According to what a study presented at the Digestive Digestive Disease Week 2025 in San Diego and not yet subjected to a peer revision, this fear would however have been unfounded, because the risk of transfer of “contaminated saliva” would be almost null.
Long baci fans … The research involved 10 couples, each of which composed of a healthy person and a person with celiac disease. After eating ten crackers each containing gluten, the healthy participants gave a long French kiss of at least one minute to their partner – once after waiting for five minutes, another time without waiting but drinking 120 ml of water.
… and safe. From the results it emerged that Only two of the 20 kisses exchanged were in a saliva transfer with a quantity of gluten over 20 ppm (parts per million) – The maximum “acceptable” level for celiacs. None of these two kisses was following water consumption, and only one was followed by a positive urine test in gluten. None of the celiac people, however, reported symptoms in the six or twelve hours following the kiss.
Analyzing the saliva of those who had eaten the crackers instead emerged that the gluten content was well above 20 ppm even after 30 minutes and after drinking 120 ml of water.
Question of sensitivity. According to Mahima Swamy, a researcher at the University of Dundae, in Scotland, the results of the study should reassure the celiacs: however, it remembers, it is still important to keep in mind that gluten sensitivity varies from person to person, therefore Those who are very sensitive should pay more attention.
