Regarding diet, the one thing there seems to be a very clear correlation with for me, is dairy and asthma. I initially gave up dairy some time back, along with meat, when I went 'macrobiotic' for a few months. I didn't expect the result, I wasn't looking for it or hoping for it, in fact I'd never thought about it. But my asthma symptoms cleared up, almost entirely - apart from a week when I had a bad cold, when they returned quite strongly, but went again as soon as the cold cleared up. I stopped using both inhalers.

After I reintroduced dairy at a reduced rate, the asthma symptoms returned, also at a reduced rate. So I started using inhalers again, but less frequently. I've since decided that the asthma - and the cholesterol - really isn't worth it, so I use subs for the most part now. Cheese can be an occasional temptation, though it's becoming less and less so, mainly because I know when I've eaten it; half an hour later my lungs begin playing like an accordian. So it's pretty much on the banned list now, along with milk and butter.

Also prior to the point I went macro, I'd started developing rheumatic type pain in knees and hips, to the extent that I would walk downstairs sideways to prevent knee pain. I hadn't got to the point of seeking medical intervention, so no meds stopped, but that went, and never returned. Which I was most thankful for. There's a less clear correlation there, as for one thing I'm eating more fish of late, but I suspect there may have been a link with so-called 'inflammation causing' foods which I now eat little of.
