I personally do not think the alison vickery website has accurate info re: MCAS and some of her diet recommendations are things that are not low histamine and would have probably killed me if I'd eaten them back in 2015. The best food/diet website I have ever found for MCAS is the "SIGHI" diet from Switzerland which has everything translated into English (and other languages). I no longer have any food restrictions but I followed the SIGHI diet religiously for about 1.5 yrs. I actually also have an MCAS specialist and am happy to give his name by PM although he remains closed to new patients at present. Luckily I only went to the ER once (when I was admitted to the hospital for a week by Dr. K) b/c I had reached the point of becoming allergic to all food but water back in 2015. I have an EpiPen but have never had to use it b/c back at that time, my rescue med, Atarax, worked so well for me. Without the Atarax, there were a few episodes that I think would have progressed to needing Epi.
