Recent reports suggest that caffeine consumption is associated with in
creased 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 c
onsumption of caffeine reaches 200 mg or more total cholesterol signif
icantly increased in males. Low density lipoprotein cholesterol concen
trations were somewhat increased in males who consumed 200 mg or more
(p<0.01 for a linear trend). In women, triglyceride levels significant
ly increased when dietary caffeine intake was 200 mg or higher. Dietar
y caffeine intake may be a factor to consider when evaluating serum li
pid levels.
