BRISTOL, UNITED KINGDOM — A new study found that a teenager in the U.K. went blind after eating nothing but junk food since elementary school.<br /><br />The unnamed boy got into a habit of only consuming french fries, white bread and Pringles chips, CNN reports. His diet also included slices of processed meats and sausage.<br /><br />When the boy turned 14, the teen found himself feeling unusually tired and paid a visit to the doctor. He was found to have anemia and low vitamin B12 levels. The doctors gave him some vitamin injections and advice on how to improve his diet.<br /><br />A year later doctors found signs of hearing and vision loss but they weren't able to link it to his poor diet, because the boy had a normal body mass index and showed no signs of malnutrition, from the outside.<br /><br />By the time the doctors realized his questionable eating habits had everything to do with his worsening health, it was too late, the teen had become permanently blind — at the age of 17.<br /><br />According to a press release by the researchers, the boy had developed a case of nutritional optic neuropathy, which is actually reversible if caught at an early stage.
