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.

                        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.
