Have you heard??
A 19-year-old in the UK went blind and suffered hearing loss … because of his diet. Seems since he was a young boy, he ate nothing but fries, potato chips, white bread, and processed meat because of an eating disorder callled ARFID - Avoidant-Restrictive Food Intake Disorder. A condition where those suffering from it will often avoid food with a certain texture, smell, taste or appearance, or only eat it at a certain temperature.
After years of his terrible diet, he had extremely low levels of B vitamins, vitamin D, and other nutrients necessary for good health which caused something called nutritional optic neuropathy, which causes damage to the optic nerve.
