Experts warn of the dangers of "vain eating" after a 17-year-old suffered from irreversible vision loss after living on a diet of chips and chips,
Eye doctors in Bristol took care of the young man after his vision worsened to a degree of blindness.
Since leaving elementary school, the teenager has only eaten fried potatoes, pringles and white bread, as well as a random slice of ham or sausage.
Tests revealed that he had severe vitamin deficiencies and malnutrition.
Extremely picky nutritionist
An adolescent, who cannot be baptized, saw his GP at the age of 1
Three years later he was taken to Bristol Eye Hospital for progressive vision loss, Annals of Internal Medicine reports.
Dr. Denise Atan, who treated him at the hospital, said: "His diet was essentially a serving of chips from the local fish and chips shop every day. He also dined on chips – Pringles – and sometimes sliced white bread and occasional slices of ham, not really any fruit and vegetables.
"He explained this as an aversion to certain textures of food that he really couldn't bear and so chips and chips were really the only types of food he wanted and felt he could eat."
p Atan and her colleagues checked vitamin levels and found that it was low in B12, as well as some other important vitamins and minerals – copper, selenium and vitamin D.
overweight or underweight but severely malnourished.
"He had lost minerals from Bo No, which was really quite shocking for a boy his age."
In terms of vision loss, he meets the criteria for being blind.
"There were blind spots right in the middle of his sight," says Dr. Atan. "This means that he cannot drive and it will be really difficult for him to read, watch TV or distinguish between persons.
"He can walk alone, although he has peripheral vision. "
Nutritional optic neuropathy – a condition that a young person has – is treatable if diagnosed early. Left too long, however, the nerve fibers in the optic nerve die and the damage becomes permanent.
Dr. Atan told cases this was fortunately rare, but parents should be aware of the potential harm that can be caused by picky eating and seek the help of specialists.
For those concerned, she advises: "It is best not to worry about being picky. instead, calmly introduce one or two new foods with each meal. "
She said that multivitamin tablets can supplement the diet but are not a substitute for healthy eating.
" It is much better to take vitamins through a varied and balanced diet, "she said, and added that parts of certain vitamins, including vitamin A, can be toxic "so you don't want to overdo it."
Dr. Atan said that vegans are also at increased risk of B12 deficiency vision problems if they do not replace what they may lack when excluding meat from their diet.
"Nutritional yeast is a way to add B12 to your diet," she said. Sources of vitamin B12 for vegans include:
- cereal snacks enriched with B12
- unsweetened soy drinks enriched with vitamin B12
- yeast extract, such as Marmite, which is fortified with vitamin B12
Rebecca McManamon, consultant nutritionist and spokesman for the British Dietetic Association, said restricted diets can happen for a variety of reasons, including eating disorders, allergies and autism, and need specialized evaluation.
"It is also worth noting that, since 2016, the UK Government has recommended daily supplementation of Vitamin D (10 micrograms / 400 international units) for all between October and March as we are unlikely to receive enough from
"A multivitamin supplement is recommended for all children up to their fifth birthday. "
