I usually mince garlic in my salad bowl. However, if I swallow too large a piece, such as half a clove or so, I feel like retching. If the pieces are small enough, no problem. Does anyone else have this problem, and what causes it? I figure the sulphur is a prime ingredient and that I may have a mild allergy to sulphur. That’s just my WAG.
Are you able to see yourself in a mirror?
Hmmm… And it IS a full moon.
Yep…check for extra long fingernails and extra pale skin. If present, move to Transylvania.
Pssht. Transylvania is so 1800’s. I recommend Transsexual Transylvania! Where you can see lots of sweet transvestites.
…we’re not helping, are we?
I myself like garlic, but too much…like a whole clove shoved in the meatloaf and swallowed…and a while later I will definately yawn technicolor. 
I’m fairly sure that garlic flavor and odor does owe something to sulfur compounds, but IIRC, garlic concentrates and owes much of its flavor and odor to selenium compounds. And if you’re allergic to the one, you may well be allergic to the other; they’re closely related elements whose compounds have quite similar properties. IANAMD or dietitian, but it’s something probably worth having your health care professionals check out for you.
Thanks for some actual info, Polycarp, especially after one frivolous attempt at humor and several imitators who have nothing better to do than replay the same joke; however, I eat the garlic and not concentrates, and I have no reaction if the garlic is minced. BTW, the benefits of garlic come from the sulphur and not so much from the selenium compounds. If I were allergic, one would think I would have a reaction to the minced garlic, which I don’t. Anyway, it’s not that important to have it checked out. I’m really surprised that nobody else has that reaction. But then again how many people actually eat half a clove or so of garlic? I was wondering if this is a natural reaction, but either people here don’t eat that or don’t have the reaction, or are not 'fessing up.
I don’t have immediate retching, but I definitely have digestive discomfort from eating garlic above an extremely minimal amount. Onions also bother me. I have been comprehensively tested for food allergies, with none indicated. Mine seems to fall under the category of a food intolerance. It could be a basic chemical/ mechanical irritation of the digestive tract.
“IIRC, garlic concentrates…”
I didn’t mean a reference to health-food garlic concentrates, but the idea that Allium sativa plants take selenium from the soil and concentrate it in their tissues. That’s why I was making a guess about sensitivity to selenium compounds, especially if you had had a sensitivity to sulfur compounds. Sorry for the misleading phrasing!
