My name is Mark Calderwood, MD. I’m currently a busy practicing ophthalmologist (eye MD) in a small western town of Montana in the shadows of the Rocky mountains. I have practiced medicine for 24 years, 18 years as an eye doctor. My interest in nutrition has been ongoing for the past 15 yrs and like most physicians is self taught. I began in earnest 5 years ago after reading the seminal work of Gary Taubes Good Calories Bad Calories. Like so many who have read this work it was an epiphany. As I explored this facet of life more critically I realized there was a dearth of common sensical information regarding basic nutrition priniciples and that current dogma is so biased as to be meaningless and more importantly harmful. This blog is my small attempt to contribute some of my knowledge and experience to those searching for assistance to a more healthful and meaningful life. I do not pretend to be an expert nor have all the answers to the great health questions of our times, but I believe strongly that it is time for us to be less passive and more proactive in answering important questions that affect each and every one of us.
