as for kids, i always gave my son what we were eating and made it clear if he didn't eat it, he would go hungry and definately not get anything else or pudding. now, at 16 he is a human dustbin. even eats sprouts. i think picky eaters are mostly made by parents (except in some cases where there is a clear problem e.g. phobia or illness). sometimes ingenuity is required i.e. homemade veggie burgers or hiding the vegetable substance, but then telling them what they have eaten when they enjoy the meal helps to change their perspectives too x
