I don't have evidence that hormones in beef affect humans. Do you have evidence that they don't? Personally I would rather not eat it without such evidence.
I just quickly googled and found this on the website of the American Public Health Association:
"By contrast, the US government position is that hormone residues in beef from adult cattle pose no threat to human health. This assumption of safety, however, has remained untested by long-term epidemiologic studies and instead relies on dated research concerning the ability of estrogen (estradiol) to mutate genes. This policy fails to reflect more recent research that hormones and hormonally active chemicals may exert their toxicity instead via epigenetic changes.12,23"
Do you carry a cell phone? Because a lot of people believe that carrying and using cell phones over long periods of time will cause cancer due to the long term exposure to electromagnetic radiation. There is no evidence that this is the case, however, nobody has proven that they DON'T. And not enough time has passed to really know the long term effects.
