Cholesterol: where science and public health policy intersect.

Current US guidelines for cholesterol recommend limiting intake of cholesterol to <300 mg/day for the general population and <200 mg/day for individuals with elevated low-density lipoprotein cholesterol. These recommendations, however, are at odds with international (e.g., Canada, United Kingdom, and Australia) guidelines that provide no specific numerical recommendation, but instead recommend reducing total fat intake and shifting fat consumption away from saturated and trans fats to unsaturated fats. A conference was held on December 3, 2008, to evaluate the data supporting current US nutrition policy recommendations to limit dietary cholesterol and analyze the consequences of this policy on the eating patterns and health of the US population. This review is a summary of the information and perspectives presented by conference speakers and discussed by conference participants.
