I am not surprised. One can see the same trend when it comes to grains. The guidelines published in 2011 encourage Americans to cut back on refined grains and replace them with whole grains, but they still suggest that it is okay to consume up to half of our grains as refined grains. That’s unfortunate, since there’s been even more research evidence in the past five years that refined grains, such as white bread, white rice, and white pasta, have adverse metabolic effects and increase the risks of diabetes and heart disease. “Big Agriculture”, “Big Dairy” and “Big —” [you fill in the blank], somebody is pulling somebody’s else’s strings to keep America “healthy”. But whether or not today’s dietary guidelines are entirely based on scientific evidence versus special profiting interests is debatable, and more than likely, wrong.
