Food for thought
Although I don't feel sufficiently qualified to be of real help, my first advice is to seek out as much organic or bio-dynamic food as possible and to eliminate processed food totally from your diet. As more and more people are being advised by their doctors to omit certain foods from their diet, one has to ask why so many people are unable to tolerate these foods any longer?
The answer is no doubt complex but the reality is much of our food is being produced in an increasingly intensive way, the main criteria being price not quality. In very intensive production systems, animals and plants are being pushed beyond their natural limit. Consequently, everything is cracking at the seams and it's one crisis after another.
