For these with celiac illness, kissing may cause extra than simply romantic jitters. The concern of inadvertently ingesting gluten via a kiss was actual for lots of the contributors in a 2022 examine revealed within the journal Digestive Disease and Science.
However, some new research may put the fear to relaxation. Data from a small examine set to be offered May 5 at Digestive Disease Week 2025 in San Diego, California discovered that it may possibly’t be handed via a kiss, even when a associate has simply eaten a snack full of gluten.
“Everyone worries about whether gluten is getting into their food at a restaurant, but no one really looked at what happens when you kiss afterwards,” examine co-author Anne Lee, an assistant professor of dietary drugs at Columbia University, stated in a assertion. “The advice we gave about kissing and celiac disease was based on precaution and assumptions. We were using our best judgment. I felt it was important to do research to see if there was any actual risk.”
Celiac illness is an autoimmune dysfunction wherein the physique can’t tolerate gluten. Gluten itself is a protein discovered within the wheat plant and in addition barley and rye. It is discovered in lots of kinds of pastas, bread, noodles, tortillas, and granola and helps meals maintain its form.

While gluten was nonetheless current in salvia after kissing a associate who had eaten the saltines after which drank water, the quantity was lower than 20 components per million in all circumstances. That quantity is taken into account secure and allowed in lots of gluten-free merchandise.
“For clinicians, we can now say to patients, ‘You don’t have to go to extreme measures,’” Lee stated. “Patients with celiac disease can be more relaxed, knowing that the risk of gluten cross-contact through kissing a partner who has consumed gluten can be brought down to safe levels if food is followed by a small glass of water.”
Those with extreme allergic reactions to peanuts and even shellfish ought to nonetheless watch out earlier than locking lips, as allergens blended with salvia may cause a response.
The information from this examine remains to be awaiting peer evaluation. Digestive Disease Week is a giant gathering of physicians, researchers, and teachers within the fields of gastroenterology, hepatology, endoscopy, and gastrointestinal surgical procedure from world wide.
