“Dr. Knobbe’s thesis that macular degeneration is due to dietary causes is well-supported by his research. Drawing on the observations of Dr. Weston A. Price, who studied traditional cultures living on unrefined and unprocessed foods, the author makes his point quite clearly: Our present-day diet is a major culprit in the proliferation of not only AMD, but most likely for many other degenerative diseases of civilization as well. Here is where so many current studies are woefully behind; the answers are right in front of us if we dare to look. Dr. Knobbe has done just that, and he deserves great credit for bringing this topic to the public with this very readable book.” *

“I have found Dr. Knobbe’s theory well researched and presented in his book. Although no one can accurately say exactly what the incidence of AMD was in the early 1900’s, he presents a compelling argument, based in fact, that not only is AMD on the rise and reaching epidemic proportions, but it’s coincident with the introduction of processed, nutrient deficient, foods. Perhaps most compelling is, after reading his book, I now find myself taking extra chair time to discuss dietary issues with my patients. I would say this is a must read for any eyecare provider, but particularly those practicing primary eyecare with the goal of preventing AMD.”*

“In our opinion, Dr. Knobbe has uncovered an important connection between diet and age-related macular degeneration that has the potential to prevent hundreds of thousands, if not millions, of people from progressing to the advanced stages of this disease.”*

“As Founder and President of the Macular Degeneration Association, a 501 (c)(3) tax exempt non-profit organization, whose purpose it is to educate and help prevent vision loss from age-related macular degeneration (AMD), I read and studied Dr. Knobbe’s book, Ancestral Dietary Strategy to Prevent & Treat Macular Degeneration. I must say, I was surprised – somewhat shocked – by his hypothesis and referenced supportive research. Dr. Knobbe has relied on the fact that AMD was once a rare disorder – in fact – it was rare just about 85 years ago, prior to 1930. Today, AMD has reached epidemic proportions – worldwide. Knobbe’s hypothesis – concludes that AMD develops because of the ingredients of processed food.
His research and book also lay out plausible biological mechanisms whereby processed food consumption, which is associated with vitamin and mineral deficiencies and certain toxicities (e.g., from sugar and vegetable oils), ultimately causes this disease. In his book, Knobbe also provides a fundamental nutrition plan to reduce the risk of getting AMD and avoiding its progression.
For these reasons, I have invited Dr. Knobbe to be a speaker at each and every one of the Macular Degeneration Association’s patient education conferences in 13 cities across the U.S. I highly recommend his book to anyone who desires to prevent and/or treat this dreadful disease. Finally, we are finding that attendees at our conferences are generally impressed and convinced, that Dr. Knobbe’s hypothesis and research, just makes good sense. I am convinced that his message is of critical importance to all of us, but especially those who desire to preserve their precious gift of sight.”*

“It is fairly infrequent that I am asked to review a book for Price-Pottenger as I am simply too busy. A while back, Joan Grinzi, Executive Director of the Price-Pottenger Nutrition Foundation, gave me the Review Copy of Ancestral Dietary Strategy to Prevent & Treat Macular Degeneration, by ophthalmologist and author, Chris A. Knobbe, MD. She asked me to take a brief look at it and give my opinion of whether we should think of recommending it. It quickly captivated me so that it received WAY more than any brief glance.
AMD or age related macular degeneration is a misnamed eye condition, which is rapidly increasing in frequency in the U.S. I say misnamed, due to the fact that it is not age related any more than cancer and heart disease are age related. There are millions of people at advanced ages who have none of these conditions. I would re-name it D&LMD for Diet and Lifestyle Related Macular Degeneration, to be more accurate.
As I read through Dr. Knobbe’s book, I was pleasantly surprised and then even astonished to find an MD Professor of Ophthalmology with both such an open mind as well as such a good grasp on nutrition and reality even when it directly contradicted his medical school training. Yes, this is likely the best book ever written on AMD, but saying that is doing it a disservice since this book should be read be everyone who cares about their current and future health or the health of their loved ones. Knobbe does such a grand job of exposing frauds and lies regarding diet and disease, that his book could just as easily be re-named Everything You Need to Know About Diet and By the Way It Will also Help Your Eyesight. This book has my highest recommendation for anyone interested in protecting their eyesight (and their health) as they get older.”*

“I was introduced to Chris’s work at the Ancestral Health Conference in 2016. I was already well informed about the effects of modern diet/lifestyle on many major chronic diseases such as diabetes, many cancers, cardiovascular events and dementia. As I listened, I realized that it was blindingly obvious (excuse the pun) that the retina was no different to any other complex vascular structure – of course, it would be adversely affected by the same factors identified in other chronic diseases. How, as a doctor myself, did I not realize this before?
But a hypothesis must be backed up by data. Chris presents a compelling review of data from 25 nations, showing that the incidence of AMD, very rare prior to 1930, has risen in parallel with the displacement of traditional diets by processed ‘Western foods.’ This mirrors the same data for other chronic diseases as mentioned above and is robustly backed up by known biochemical mechanisms beyond the scope of this review.
I am convinced on the basis of Chris’s evidence review – and saddened by traditional Western medicine’s delay in not making consideration of lifestyle factors an immediate first step in preventing and managing all chronic diseases, of which AMD is hugely important. Hopefully the tide is turning, and this work deserves to take credit for being a powerful force towards reducing the incidence of lives affected by AMD.”*

“I just finished reading Ancestral Dietary Strategy to Prevent & Treat Macular Degeneration. Following extensive research, this book is, without doubt, the most comprehensive and useful study on macular degeneration I have found. As a physician and author myself, may I commend you, Dr. Knobbe, on an excellent book, superbly researched and written. Congratulations!”*

“I found your lecture on Saturday a major contrast to what patients are usually told by their Ophthalmologists/Retina Specialists. Few doctors were taught or take it upon themselves to study the connection between the illnesses they treat and the diets of their patients. Your comments are very “eye opening” to all of us. I hope that you continue to give lectures to as many organizations as you can fit into your schedule.
I think we all left ready to share your recommendations to our family and friends.” *

“I’ve worked in the Vitreo-retinal field for over 28 years, seeing literally hundreds of thousands of AMD patients. I’ve seen theories and treatments come and go. I remember when the vitamin/supplements studies came out and how the market became saturated with “nutritional” products claiming to prevent AMD advancement. Yet here we are, decades later, and AMD is still on a rapid rise. Dr. Knobbe’s hypothesis is the ONLY prevention theory that backs up all statements with fact and is meticulously researched pure data, without any big-business sponsored influence. I can only imagine what the vitreo-retina clinical landscape would look like today if every ophthalmologist counseled their patients with Dr. Knobbe’s compelling research 3 decades ago. I think the most exciting part of this research is the message that it’s not too late to implement Dr. Knobbe’s nutritional lifestyle changes to help avoid the terrible diseases relating to aging under a “Westernized” diet, including macular degeneration.”

“After getting a diagnosis of early-stage AMD, I got online in search of a natural, holistic path to control this condition. During this search, I found Dr. Chris Knobbe’s book, Ancestral Dietary Strategy to Prevent and Treat Macular Degeneration.
I started the Ancestral way of eating immediately.
The date of my initial diagnosis was January 3, 2017. At that time, my vision in my right eye was 20/50, and in my left eye it was 20/40. My next visit with my eye doctor was March 29, 2017. At that time my vision in my right eye was 20/40 and the left eye was 20/25. September 29, 2017 was my most recent exam. On that date my vision in my right eye was 20/30 and in the left eye 20/20!
Thank you Dr. Chris Knobbe for your wonderful book. It has given me the right path to improved eye health.” *
(Update, April 9, 2017): Dr. Chris, I just got back from my 4th visit with [ophthalmologist] Ann Ranelle, DO and I’m happy to say that my vision improved again. It is now 20/25 and 20/20 (no glasses at any exam). She even said that she could see a small improvement in my macula! I told her about your book… so I decided to send her your book as a gift.”
— Katie Peterson
“I take great comfort from your presentation and your book. I hope the dietary changes will result in improvement for my AMD and others.
The conventional treatment has not been encouraging but rather directed at the eventual and inevitable severe loss of vision for AMD patients. As a therapist, it is very sad to see groups of people who have given up! My hope is that this book will open doors to more acceptance of new ideas and research around the world for AMD patients.”
— Carol Cooper
“After reading Dr. Chris Knobbe’s insightful and scientifically based book “Ancestral Dietary Strategy to Prevent & Treat Macular Degeneration,” I have been following his nutritional recommendations. Just saw my retinologist and vision left eye was 20/40 four months ago, now is 20/30, but the tech said almost 20/20! The right eye where the cataract was removed was 20/60, is now 20/50. Retina holding – no change. I have not been taking vitamins. Again, thank you Dr. Knobbe for this research.”*

“In late September (2017), I had the opportunity to be in attendance of a Macular Degeneration Association conference in Austin, Texas. I happen to be completely blind from an accident, however, I am always interested in learning more about healthy fuel for my body. I had the opportunity to hear Dr. Chris Knobbe present. He was sharing research findings and concepts conveyed in his book. While I have done a tremendous amount of nutritional research, I have only been able to assimilate puzzle pieces and never able to put the puzzle together until now.
Dr. Knobbe does a marvelous job of demonstrating how he can be scientific, analytical and down to Earth. He was able to put the puzzle together for me. While I am not concerned about poor nutrition causing me to lose my vision, I am very concerned about how poor nutrition can negatively impact my overall health, and the overall health of my loved ones, friends, and neighbors. Dr Knobbe’s work in written form is a great deal of data for your mind to digest. The data may motivate you to put a great deal more effort in what digestion takes place in your body. While I am happy and successful as a person that is blind, I would certainly invest that effort to eat exactly right, if I could regain my vision as a result. I plan to do the best I can to prevent other catastrophic conditions from compounding my situation. I sincerely hope that you will make the investment to achieve the same. Start here with reading data that has already been so incredibly and superbly compiled for you. I can testify that life isn’t over if you lose a portion or all of your vision, but I will say that it is worth avoiding, if at all possible.”

“Dear Dr. Knobbe,
First, the presentation you gave at the MDA [Macular Degeneration Association] meeting was the most informative of the day.
Second, your book on the ancestral dietary strategy which expanded on that presentation was extremely clear and compelling.
Third, I am looking forward to your next book, Ancestral Diet Rx.” *
Very Truly Yours,
“Good afternoon Chris….i just finished your amazing book and you have changed my life and my families….
It is going on 2 weeks and I have completely gotten off sugar, white flour, and all vegetable oils…
I have only been eating clean….it is very hard because we are very social — always going out, but there is nothing that will stop me from eating clean….Thank you for that — and I know I am going to reverse my [early] AMD…with the help from your book and God…
God Bless you Chris….please let me know when your new book comes out…
I will be first in line…”*
