Blood lycopene levels were linked to thinner carotid artery walls
A review of adult studies found an association with an artery-wall marker, but it cannot show that lycopene prevents cardiovascular disease.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Higher blood lycopene levels were associated with a thinner carotid artery wall, a marker used to assess early artery disease. The association for beta-carotene was marginal. These findings describe a relationship between blood and artery measurements; they do not establish that carotenoids protect the heart or that taking supplements would help.
Cross-sectional associations cannot establish cause and effect. This abstract-based account also lacks study-level details about adjustment for other factors and the cutoffs used to define carotenoid levels and artery-wall thickness.
What the researchers measured
The review combined studies relating blood carotenoid concentrations to carotid intima-media thickness, a measure of artery-wall thickness. Because these were cross-sectional associations, the analysis cannot establish whether carotenoid levels preceded differences in the artery wall.
Patterns differed between participants
The lycopene association appeared stronger in men. Blood pressure and other cardiovascular risk factors also appeared to influence the results, leaving uncertainty about how much the observed patterns depend on participants' broader health profiles.
