This story has been published on a handful of news sites today, regarding a 17 year old, who has turned blind as a result of poor diet (he would only eat white bread, ham, pringles, chips). I feel for him, he is said to be an extremely fussy eater who struggled to eat anything else.

I'm posting this to remind us to work on the variety in our diets

The mum has spoken anonymously, unfortunately she says the eyesight damage is irreversible.
