This interesting approach just raises more questions than it answers; experiments with sample size n=1 being run by non-medically trained individuals are unorthodox and generally suspect in the modern medical climate.
here's another experiment for you that I've run on myself:
When I consume products that contain wheat, I feel sick. When I don't, I feel fine. Sample size n=1, and I am not medically trained. What conclusions, if any, do you think I can draw from my experience?
