Just wanted to add something that happened to me. I was really ill for a long time, had symptoms of candida and was not digesting my food properly, also had weight loss and poor wound healing. I did a very strict diet of veggies and fruits, wheatgrass for a while and could never get my pH over 6.0. Then I discovered I was deficient in omega 6/GLA and started taking evening primrose, one week later my pH was 7.5! and I could eat acidic foods and still have a pH around 7. Now no matter what I eat it never goes below 6.5. All of my symptoms have been reduced 90%. I have a feeling that being deficient in fats reduces bile. Otherwise I dont know how this worked to raise my pH. Any ideas?
