Happy New Year! Welcome to 2009!
My new blog is called "Olio Engineer". Check out the first post.
In her April 22 Earth Day news release, Pelosi said, "The Bible tells us in the Old Testament, 'To minister to the needs of God's creation is an act of worship. To ignore those needs is to dishonor the God who made us.' On this Earth Day, and every day, let us pledge to our children, and our children's children, that they will have clean air to breathe, clean water to drink, and the opportunity to experience the wonders of nature."Apparently, the Bible doesn't actually tell us that (in the Old Testament or the New Testament). Speaker Pelosi's office didn't respond to Cybercast News Service's questions about the location of this supposed Bible verse. Various Bible scholars (such as Dr. Claude Mariottini) weren't familiar with the particular passage.
But three years later the association changed position — not because of new data, Mr. Taubes writes, but because Dr. Keys and an ally were on the committee issuing the new report. It asserted that “the best scientific evidence of the time” warranted a lower-fat diet for people at high risk of heart disease.Years later, a Senate committee issued a report written by a non-scientist that relied "almost exclusively" on one particular nutritionist.
That report impressed another nonscientist, Carol Tucker Foreman, an assistant agriculture secretary, who hired Dr. Hegsted to draw up a set of national dietary guidelines. The Department of Agriculture’s advice against eating too much fat was issued in 1980 and would later be incorporated in its “food pyramid.”Tierney also explained how as politicians became more convinced that the science was irrefutable, scientists began to risk their reputations if they questioned the "fat is bad" theory:
The scientists, despite their impressive credentials, were accused of bias because some of them had done research financed by the food industry. And so the informational cascade morphed into what the economist Timur Kuran calls a reputational cascade, in which it becomes a career risk for dissidents to question the popular wisdom.John Tierney also has a follow-up article about this topic: How the Low-Fat, Low-Fact Cascade Just Keeps Rolling Along
