Nonceliac is drinking guinness, celiac is drinking wine. Stuff happens. Can the celiac get a gluten reaction from the fooling about that results? I'll upvote answers that speak to actual experience, not theory. In theory, vegetable oil doesn't contain soy proteins...
Yes, if you are celiac you can become glutenized by kissing someone who has recently eaten of drank gluten containing food or drink. It seems to be a known risk. I have always been careful about eating gluten containing food or drink around my girlfriend who is celiac.
Cosmetics like lipstick are also a risk for kissing as these can contain gluten. Also for females, don’t forget to brush any gluten crumbs out of mustaches and beards.
Remember though that celiac disease is a type IV hypersensitivity reaction and not a type I hypersensitivity like other allergies such as peanut allergy. This means you can only be glutenized by actually swallowing gluten proteins and not through skin contact.
Seeing as there is no scientific evidence on this subject I propose an scientific experiment to acurately quantify the risk. I would require the following:
*Replication of experiments is important.
However I suspect my girlfriend would object, even if it is in the interests of science.
I was recently glutened by something, and whatever it was, the amount was so small I can't figure it out. Three-four days later, I'm still not right. I would totally not take a chance on it until after they've rinsed several times and wiped their lips, and washed their hands should that kissing lead to anything else...
Yes - but don't limit your partner because of this.
Coeliac is an immune response to, among other laminar proteins, gliadin and hordein - gliaden being a component of gluten, and hordein being a water-soluble protein present in barley. Guinness, like most beer, contains significant hordein.
However, since hordein is water soluble, it's easily washed away. Just have your partner drink a little water before planting one on you, focusing on wetting their lips; should be fine.
My husband went completely gluten free for this reason....He doesn't drink beer so it was other things. I have Celiacs and would get hives around my mouth about 5 months after I went completely gluten free (cutting out ALL cross contamination risks) It was the only thing it could have been....my granny will kiss my face to this day and I will have a hive or welt come up mainly if she has just eaten....
