That article uses really specific rhetoric to instill (from an unprivileged criticism only looking from the outside in) the notion that because the FDA is slow, they are doing their job of protecting the public poorly. Truth is, like I said, because nutrition science is slow, among other factors (like industry factors. The FDA can't overnight a policy that food companies can't comply with and suddenly the entire nations food supply and economy collapses) the FDA deliberates in all of its policy changes. Sure it makes mistakes like any organization, but it's literally the best we have in terms of regulatory agencies on earth. The FDA is more technologically advanced and has more resources for science and knowledge capture than any other food regulatory board on earth besides MAYBE the European Commission. No board tied up with government dollars is absent of criticisms, but it's the best we have and always the better decision than to trust uneducated opinions on dietary knowledge. People did the same thing with the CDC. People with forum and blog degrees in infectious disease disregard the statements of the CDC with fiery criticism regarding every kind of illness that hits our shores. Mind you, the HuffPost is written by an accomplished individual, but he's still only looking from the outside in, and pushing a rhetoric (that because the FDA is slow, they're bad at protecting the country) that I don't completely agree with or find useful in rebutting my point that the FDA is the best we have and infinitely better and more qualified than a common person's wisdom on what they should eat.
And no. Common sense isn't useful or quantifiable in discovering truth or establishing policy that yields an expected outcome. Some people's common sense is that drinking fruit juice is beneficial to your health. The truth is not so black and white. It has vitamins, but it's loaded to hell and back with fructose.
