Absolutely agreed. The CDAI is too open to subjective feelings and variables, but it is probably preferred for approving substandard pharmaceuticals with little measurable longterm benefit.
For doctors to harp on about alternatives not being "scientifically proven", like enteric coated fish oil, quality probiotics, dietary additions/exclusions, and LDN, while the CDAI is used as a basis for many profitable/ineffective/toxic treatments just sends my BS meter off the scale.
