Can gluten pass through a kiss? This question (which concerns those suffering from celiac disease) has decided to investigate a team of scientists who came to the conclusion that sufferers could enjoy the kiss without worry, even if their partner had just consumed a gluten snack.

Researchers point out that patients with celiac disease may feel safe by knowing that the risk of contamination through the kiss is small and can be particularly reduced if the consumption of food is taken by taking a small glass of water.

The study will be presented at the Digestive Disease Week.

The experiment

The researchers, led by Assistant Professor of Nutrition Medicine at Columbia University, if Lee, worked with ten couples, in which one partner had celiac disease.

At each session, the companion without celiac disease ate ten salty crackers and then the couple kissed for ten seconds. In one session the partners waited five minutes before kissing and drank 120 ml of water before kissing.

In both cases the researchers found that The gluten transferwhich was measured in the saliva of a partner with celiac disease, was minimal in the majority of participants.

Although gluten was still detected in saliva after kissing in the event where participants drank water, it was found that the amount of gluten was less than 20 parts per million, the level that is considered safe and allowed to gluten -free products.
