I've got this, but a relatively mild case compared to most people. I contracted it in 2013 and only a full red-meat meal will trigger it or very large amounts of high-fat cheese. I rarely ate red meat and there was very little information about the syndrome when I got it, so it took me a couple years to figure out why I'd have an allergic reaction every few months. It's been so long now that a lot of dishes that are red meat just seem unappealingly fatty and heavy now. I no longer really miss it. Plus I can have cheese or even a single slice of bacon and it doesn't cross the threshold. Honestly it probably limits me to the recommended daily amounts of many high-fat ingredients.
