A Boy Ate Only Chips And French Fries For 10 Years. This Is What Happened To His Eyes.

  • Published: 10 September 2019
  • This case is based on publication in literature by Harrison R, Warburton V, Lux A, Atan D. Ann Intern Med. 2019 Sep 3. Link below. Non-clinical elements (e.g. initials, story details, etc) are adapted. Peer Review: Dr. Nikhil Parelkar.

    I originally had another case for video of a vitamin b12 deficiency I saw as a student about a girl on an overly strict diet. I didn't release it because the details were more difficult than I would like for a video. The clinical principles and science of that case and this one are the same.

        20/200 is legally blind if that is the best you can get with correction. I have a 20/200 rating in one eye, but I am not considered legally blind in that eye because it is easily corrected to 20/20.

                I don't know you, but I'm proud of you. I recently started watching your videos. I love them. Then I watched your previous videos on weight loss. I got to know a small part of you as a regular person who struggles like the rest of us. But you keep pushing yourself. You have goals and you do what you need to do to meet them. Its inspiring to watch your videos from 2016 to now.

                    Please please cover the British story of the boy who only ate chocolate and chips. They claim it could possibly be a vitamin A deficiency. He had gone blind in one eye.

                            20/200 is legally blind in the US? Since when? My eye doc told me 20/450 was legally blind and I'm sitting at 20/400

                            Also, that chart of blood cells made me want to see an episode of Cells at Work about B12 deficiency.

                                                            I have NEVER met an unhealthy or blind vegan. People have all sorts of idiotic provably false provably wrong beliefs about what is good or bad for their health. Sciencebasedmedicine. org is an excellent website that debunks all sorts of myths.
                                                            But don't attack animal rights vegans. Not forcing one's hunger & lifestyle upon nonconsenting animals by going vegan is infinitely more important than any health-nut's idiotic cause, like the idiots who are anti-gluten in spite of NO evidence gluten harms anybody.
                                                            Whatever trivially small "harms" to anyone's health by going vegan is OVERWHELMINGLY outweighed by not forcing one's hunger & one's health & one's lifestyle choices upon nonconsenting animals.
