Reminds me of the ads from the 50s when it said something like "4 out 5 doctors prefer Camel cigarettes" or something to that effect.
It seemingly takes FOREVER for enough people to figure out that what is being crammed down our throats (metaphorically speaking) is NOT what is best for us, it was is usually best for lining the pockets of bureaucratic fat cats.
I think in the next 10 to 15 years the whole sugar/HFCS/grain scam *might* be reversed, or at least halted. But, you can actually find websites that say that smoking has never been proven to be bad. It goes back to the lies, damned lies and medical science thing.
People too weak to follow their own dreams will always try to discourage others.
