I don't know Sandi...I hardly eat any meat and I still get horrible flares. So...don't know if a vegetarian diet would help. I eat chocolate instead!
about 18 yrs ago I started having a prob w/ beef. I liked it WELL done and it was. The sight of red meat or blood and I would get sick. I would eat the meat and before I would finish the meal I had to run to the bathroom. Two yrs later I had my gallbladder removed, I thought that was the prob, but I still have that feeling till this day. I can handle a pork chop, chicken or some fish, turkey or beef I just can't handle. I also can't handle milk, eggs, cheese, even the smell of peanuts or peanut butter make me sick. I have a very small list of things I can eat w/o getting sick. I still cook the meats for the rest of my family, but I eat chicken. The smell of the beef and such cooking can make me gag.
I've had Fibro forever, but it has gotten worse in the past decade or so, and yes I have noticed that I can't handle some foods like I used to. If I can't handle it, I eliminate it from my diet, my mother will continue to eat the foods even if she gets sick from it. My DM hasn't been dx w/ FMS, but I do believe she has it, too.
The one thing I miss eating is popcorn, I have diverticulosis. The smell of the popcorn almost brings me to my knees, but the taste of it would really bring me to my knees. lol Think about something else, Alice.
God bless. Alice.
