I was able to figure out what the things that were affecting me by keeping a food diary. My allergist told me to write down everything I ate and then when I had a problem whether it was 30 minutes later or 3 days, I could see what the problem was by comparing what I had eaten before. It worked like a charm.
Exactly!!! Congrats.
Another method is what I did: I ate exactly the same thing for the 3 daily meals for 2 weeks, each meal being different of course (3 different meals), gradually introducing other foods.
I know people that say that they can’t eat the same thing over & over or get tired of their favorite foods that way; I’m not of that typeset. I enjoy cooking with my 16qt pot and freezing food for later (and my neighbors appreciate being my guinea pigs, as the wife has dietary concerns so only half my bulk meals are prepared for her too).
Footnote: People I know claim that they don’t have time to do all that cooking that I do. I also know people that spend an awful lot of time on the toilet (some with the prior complaint). Given the 1% takeout meal I had this last Friday ended up with a toilet seat imprint on my backside and a wasted weekend, from very recent experience I vigorously dispute the “not having time to cook” argument...
And by the way, eliminating whatever it is exactly that I’m sensitive to in ‘processed foods’ arrested my weight gain and I’m happily within target range of my belt size 20 years ago.
No ‘dieting’ needed (just portion-control...middle-age brings with it certain realities...)
