Abstract
ARTICLES IN the lay press continue to advocate the use of garlic as an effective method to lower serum cholesterol levels. A recent meta-analysis1 of carefully selected trials reported that the use of garlic tablets, equivalent to approximately half to 1 clove per day, decreased total serum cholesterol levels by approximately 9%. Many of the studies cited in the meta-analysis were carried out without standardized laboratory measurements and did not control for any dietary effect. Most of the studies in the meta-analysis did not describe the method of cholesterol analysis.
