My neighborhood grocery store is displaying a wall of Cheerios boxes with this banner over the inevitable heart: “You can lower your cholesterol 4% in 6 weeks (see back for details).” I immediately turned to the back to learn that “Cheerios is the only leading cold cereal clinically proven to lower cholesterol. A clinical study showed that eating two 1 and 1/2 cup servings daily of Cheerios cereal reduced cholesterol when eaten as part of a diet low in saturated fat and cholesterol.” I like Cheerios, but come on? What clinical study? A footnote gives the reference to a study published in Nutrition in Clinical Care (1998;1:6-12). I immediately went to look for it but alas, the journal ceased publication in 2005 and is not available online or in the NYU or Cornell libraries. Want to take a guess at who might have funded the study? If anyone has a copy, please send. The FDA used to be able to demand serious scientific substantiation for health claims like this one, but no more. Congress says one study is sufficient, no matter how old, designed, or paid for. The courts say advertising is a form of free speech and protected by the First Amendment. Caveat emptor.
Update: Andy Bellatti of Small Bites reminds me that as always, Center for Science in the Public Interest was there first. Nutrition Action Healthletter talked about the study–surprise! funded by General Mills–in 2005.
