Re: Obesity
You might want to check on how many of these growth hormones, most of which have a short half-life, are actually left over in slaughtered cows, much less how many of these fragile molecules are left over after a session on a fry grill.
People are fatter now because they eat like pigs and don't exercise, but as always, no one is interested in the simple answers.
That said, I would tend to be careful of FDA pronouncements myself, but for different reasons.
