Okay, now you've got me wondering whether https://www.choosemyplate.gov (which is a revision of the Food Pyramid, which is a revision of the Four Food Groups, which is a revision of the Seven Food Groups) has any solid science behind it. Is it like climate change, where there's a consensus on the basics by 99% of the scientists, or is this a case where the U.S. government nutritionists threw up their hands and said, "Well, heck, this one looks good"?
