I have not heard of the book. My initial reaction is, I wonder what the authors definition of a cure is? Her ideas might very well cure a testing measurement or some part of the disease, but her definition of a cure and your idea of a favorable health outcome might be greatly different.
That is a problem I've found in the health care industry. The definition of a cure and my expectations can vary greatly. There are several examples that come to mind, but an example of this can be seen with high cholesterol.
Many say that high cholesterol is a disease. With that there are several remedies to cure high cholesterol. The most common high cholesterol cure are statin drugs.
The definition of curing high cholesterol and preventing heart disease might be different from what one is expecting though. Statin medications do not prevent heart attacks all that greatly on an absolute risk measurement. (The often reported relative risk is a different story).
There are studies showing overall health outcomes with taking statins as not improved. Basically, life span is not increased all that much by taking statins. So overall, a persons high cholesterol is likely cured by taking a statin medication, but the all important health outcome is not likely improved as one would hope. (Additionally statins come with common side effects of muscle pains, memory problem, etc, which is something to take into consideration.)
You can read about some of this here:
