that nickname is misleading, because alpha-gal syndrome can cause strong reactions to many products, beyond just red meat.
The alpha-gal sugar molecule exists in the tissues of most mammals, including cows, pigs, deer, and rabbits. But it’s absent in humans.
the allergy also can be set off by exposure to a range of other animal-based products, including dairy products, gelatin (think Jell-O or gummy bears), medications, and even some personal care items.
it’s possible to get over the allergy if you can modify your diet enough to avoid triggering another reaction for a few years and also avoid more tick bites.
