Ok so someone tells me that children are taller today than in the past becuase the chicken we eat has been treated with or injected with growth hormone that makes kids grow more. This sounds like total B.S. to me. Any evidence one way or the other?
No, kids these days are taller because they tend to get adequate and even over-adequate nutrition from day one, so can reach their maximum growth potential.
Chickens tend to get fed lots of antibiotics, not recombinant cGH.
