If kids are let to get away with eating some thing because there is something better,it's down to the parents to correct this at a early age or early as possible ,we all have that social condition in us ,it needs taming ,ie if your favourite food is,pork sausage you do not eat them every day,you could ,and could afford ,but what's the point,
Food should be a education ,my two boys now 15 and 16 are good eaters,but still guided by social factors ,offal is a no go but your taste buds do develop as you grow ,they do try most things and consider foods providence
They eat moules by the kilo but not oysters but they tried ,they eat raw sirloin of beef where as when I was growing up beef was well done,we should encourage youth to experiment ,
I have done work with a local school with my veg suppliers support letting them try fruits,a lot of the problems is the kids have never been given the chance to try a fruit because their parents think that they don't like it as they were bough up eating a. Certain fruit,so the kids some how loose out
