Jeffrey S. Bland

Dr. Jeffrey S. Bland is considered the godfather of functional medicine.

He holds a Ph.D. and is not a medical doctor, which has led to some criticism of his work.

Bland's expertise lies in nutrition, biochemistry, and preventive medicine.

He has authored several books on health and nutrition, with "The Disease Delusion" being one of his most notable works.

Bland's approach focuses on treating the whole person rather than just symptoms, emphasizing the role of diet, lifestyle, and environment in health.

His work has been influential in promoting the concept of personalized medicine and challenging traditional approaches to chronic disease management.
