A Teenage Boy Went Blind After Eating French Fries Everyday
A teenage boy's diet reportedly caused him to go blind, and his story is bringing light to an uncommon and potentially-dangerous eating disorder.
According to a case study in the journal Annals of Internal Medicine, the teenager went to the doctor when he experienced trouble hearing and seeing. Doctors discovered that he was vitamin B12 deficient, which led them to do more tests, and eventually diagnose him with an eating disorder called avoidant-restrictive food intake disorder (ARFID).
根據《內科醫學年鑒》（Annals of Internal Medicine）上的案例研究所述，這位青少年因為聽力和視力下降而去看了醫生。醫生發現他缺乏維生素B12，從而對他進行了其它身體檢查，最終診斷出他患有一種叫做可避免的限制性食物攝入障礙（ARFID）飲食紊亂癥。
The case report says ARFID is a relatively new disorder, which used to be called "selective eating disorder." The patient was diagnosed with ARFID after years of eating only certain unhealthy foods like potato chips and French fries.
Unlike other eating disorders, "[ARFID] is not driven by weight or shape concerns," the case report says. In fact, people with the disorder often have a normal BMI, as was the case with the patient who lost his eyesight because of his diet.
"Height and weight were average, and body mass index was normal. However, the patient confessed that, since elementary school, he would not eat certain textures of food," the case report says. "He had a daily portion of fries from the local fish and chip shop and snacked on Pringles (Kellogg), white bread, processed ham slices, and sausage."
According to the case report, people with ARFID "lack interest" in food. Their sensitivity to certain food textures is heightened, and they are afraid of what will happen if they eat certain foods. According to the National Eating Disorders Association (NEDA), the disorder can cause weight loss, lack of appetite, and gastrointestinal problems, among other issues. The association adds that people with the disorder can be scared of vomiting and choking.
The disorder caused the patient to have a confirmed vitamin B12 deficiency, and the report says the patient likely also suffered from deficiencies in the following nutrients: B1, B2, B3, B6, B9, and copper.
