said Dr. J. David Spence.
Spence, who was not involved in the study, directs the Stroke Prevention
& Atherosclerosis Research Centre at Western University in London, Ontario, Canada.
For the healthy people in this study, Spence said, the TMAO rise from choline might not be worrisome. But, he added, it might be a concern for people at increased risk of heart disease or stroke.
Spence suggested those individuals limit egg yolks, beef and other foods high in choline.
Hazen had similar advice.
