High Cholesterol and Complementary Health Practices

Approximately 13 percent of U.S. adults has high total cholesterol. Lowering cholesterol levels can slow down, reduce, or even stop plaque from building up in the walls of arteries and may decrease the chance of having a heart attack. Mainstays in treating high cholesterol include diet, weight loss, physical activity, and when necessary, drug treatment.
According to the 2007 National Health Interview Survey, high blood cholesterol is one of the top 10 conditions prompting use of complementary health practices among adults. This issue provides information on “what the science says” about the effectiveness and safety of several dietary supplements reportedly used by people with high cholesterol, including red yeast rice, flaxseed and flaxseed oil, and garlic.
