re: Even more boost with a new Saturn V . . .
Agreed, S_M.
Most of the beneficial foods act as a chemistry lab in the body of the eater, affecting particular glands and protein releases.
I suspect, though, that these folks know a little more about the process than either you or I. One point might be, as Larry points out, the amount (mass/weight) of strawberries required to get the desired effect, measured against the amount (mass/weight) of pills that could do the same thing.
Then there's the matter of strawberry allergies.
And what about those tiny seeds stuck under John Glenn's dentures?
