I tried this a few years back (and again a few years before that come to think of it) and it did make me feel much better. I gave up at the time as it was before my diagnosis and I was hoping it would make me better around people. Ditto exercise. Maybe I'll go back to it in the springtime.
I think the best diet is veg most days, meat occasionally isn't it? That seems to be the natural diet, if that word means anything.
