I'm still not comfortable recommending that people eat saturated fat with abandon, but it's clear to me that sugar, flour and oxidized seed oils create inflammatory effects in the body that almost certainly bear most of the responsibility for elevating heart disease risk.

Even low-calorie diets and vigorous exercise fail to work in the long term for at least some people.

Any drug can be used successfully, no matter how bad it's reputation, and any drug can be abused, no matter how accepted it is. There are no good or bad rugs; there are only good and bad relationships with drugs.

In my view, prescribing antidepressant drugs is too often a quick and easy substitute for developing treatment plans that address the totality of health concerns and lifestyle factors that have an impact on wellness, including emotional wellness.

To allow them to transcend their human and ego boundaries to feel greater contact with the supernatural, or with the spiritual, or with the divine, however they phrase it in their terms.

I have argued for years that we do not have a health care system in America. We have a disease-management system - one that depends on ruinously expensive drugs and surgeries that treat health conditions after they manifest rather than giving our citizens simple diet, lifestyle and therapeutic tools to keep them healthy.
