Cholesterol is a natural and necessary substance in human bodily tissues. But excessive levels of cholesterol, especially low-density lipoproteins (LDL), in the blood can cause narrowing and blockage of arteries, leading to coronary heart disease. Primary care clinics throughout the city routinely screen patients aged 20 and higher for high LDL cholesterol.

Dietary intake of LDL, in turn, works in concert with other factors to influence circulating LDL levels. You have been hired to evaluate the effectiveness of this program. Upon your recommendation, the implementing agency has agreed to conduct a randomized controlled trial. As a result, patients who volunteer for the experiment will be randomly assigned either to participate in the Gettin Out the Gunk experimental intervention, which consists.
