I agree with Thud. It's politics, and political efforts try to hide behind science when it's convenient and supports the political agenda. Using some "science" and excluding some inconvenient science is the game being played with many of today's issues, and the "anointed," who believe they know better than most, justify these actions because only they know the many will benefit. The most devious actions in the DGA issue are based on inaccurate labels and definitions such as how low carb is defined. Many studies show how ineffective a low carb WOE is while using many more carbs in studies than anyone following a low carb approach would ever consume. No wonder we have many inconclusive results that can't separate a low carb WOE from the rest. Where would we be without these "experts?"
