Dr. Swank's raw data shows the exacerbation rate before going on his diet program and after. See if this works to keep it on the right
Here is the analysis of his raw data.
Then Dr. McDougall etal tried to duplicate his results but did not use before and after but instead used a control group and sample group for their analysis.
Dr. Terry Wahls Diet extends the Paleo Diet to better address some of it's lacking. However, by all research it is too high in protein (similar to Dr. Atkins--who died). In addition it is too high in fat and far too low in fiber and carbs.
Bottom line: IMHO Dr. Roy Walford MD still had the best all around diet in his book "Beyond the 120 year diet."
