Has anyone read about Charlotte Gerson or her father Dr Max Gerson. A lot of their work concentrated on migraine and cancer, but the common factor with all health issues is that you are what you eat. Eat healthy to be healthy. That is not the total reason, but a big part of it.
Also check out Dr Andrew Saul, Phillip Day, T Colin Campbell. Check out sites like "Food Matters" "Forks over Knives". There are many others that advocate food (ideally, organic, raw, whole, natural foods, ie fruit veg, nuts, seeds and legumes) to be the answer to out health issue rather than medication, particularly long term meds, all of which have adverse side effects. You can read about them on-line. Another site worth looking into is "ihealthtube".
