I think we all have to do what we need to do to function with this disease.
Redbird--if it makes you feel better, the Low-Histamine Chef does have MCAS with anaphylaxis and has seen several of the specialists. She does state in her website that if you have anaphylaxis, or other severe symptoms, you may have to keep taking antihistamines no matter what her diet does for you. She always specifies that people may not tolerate many ingredients in her dishes, and tells people to sub in safe ingredients.
I agree with her theory that being on the standard low histamine diet is making us sicker. My hair is falling out since I started it a year ago and I'm sure it's from the vitamin deficiencies, since I can't take any, and my diet is so limited. I am slowly working on adding healthy foods to my diet, but it is a SLOW process, as you know. I really wish I wouldn't have eliminated many of the foods that I did when I started the low histamine diet because at least I wasn't dying from eating them, and now when I try the things I ate a year ago, I have severe reactions.
I don't agree with her that Benadryl is like "cocaine for your brain." The only reason that's been reported is because when you give it IV, if it's given fast, you get a high (I know this because I'm a nurse, and pt's have told me you get high when it's injected really fast). When I had my endoscopies, I was freaked out when the anesthesiologist gave it to me much faster than I would have given it, but I felt fine, just tired.
I will stay on antihistamines because I really feel they help me, especially the Zantac. I can go without them occasionally and I don't panic. I have been doing acupuncture too, and it is really helping me (especially with being able to sleep without waking up with reactions).
For the people that can eat many foods, I think her recipes would be beneficial because they include many anti-inflammatory and antihistamine ingredients. For those of us with the food-induced anaphylaxis, I think we're on our own with figuring out what we can eat...
I hope you all are well
