Do your brood eat interior organs? Do they eat pigs' ears? Do they eat aged tofu? We have a habit of assumptive that whatever foods are 'acquired' tastes, and universally hated by children, or, in few cases, everyone in their correct mind. However, once I was a micro girl in China we wouldn't have blinked an eye at noodles served under a half inch vein of hot pig fat, or tangy pig's ear salad. We would, however, have been revolted by the American child's present broiled cheese sandwich.
When it comes to food, it's not the hay itself, it's the age at which a small fry becomes acclimated to the feed. If family statesman consumption food since they recognise that it's someway incompatible or uncommon to eat it, they are warm next to it and will be less credible to scorn it once they change elder.
