Effect of dietary caffeine intake on serum lipid levels in healthy adults

Abstract

Recent reports suggest that caffeine consumption is associated with increased serum cholesterol and/or low density lipoprotein cholesterol. The authors examined the association between serum lipids and dietary caffeine intake in 179 healthy adults. The study confirmed that when consumption of caffeine reaches 200 mg or more total cholesterol significantly increased in males. Low density lipoprotein cholesterol concentrations were somewhat increased in males who consumed 200 mg or more (p<0.01 for a linear trend). In women, triglyceride levels significantly increased when dietary caffeine intake was 200 mg or higher. Dietary caffeine intake may be a factor to consider when evaluating serum lipid levels.
