Why Reading Newsweek® Magazine Can be Detrimental to Your Health
Newsweek magazine just published an article stating that reducing homocysteine levels “has no effect on your risk of heart disease or stroke.”
They base this proclamation on a study published in the Journal of the American Medical Association that evaluated the impact of modest homocysteine reduction in those who had already suffered a heart attack.
One minor fact that Newsweek failed to grasp is that homocysteine is involved in both the initiation and progression of atherosclerosis.1-3 It’s a shame that these two events (initiation and progression) are not better differentiated in the scientific literature as you will read in the following paragraphs.
The subjects in the study Newsweek reported on already had a myocardial infarction (heart attack) and thus suffered severe endothelial dysfunction. Catastrophic failure of the endothelium might better describe the condition of the arteries of these study subjects.
Since this study was done in the U.K. where dietary choices and tobacco consumption are worse than the U.S., we suspect many of these post-heart attack victims’ arterial systems were already so calcified, brittle, and occluded that it would be absurd to expect a modest reduction in homocysteine to protect against future strokes and coronary events.
This new study confirms what Life Extension® long ago stated, i.e., unless all 17 vascular disease risk factors are corrected, there may be no benefit in reducing homocysteine alone or in combination with a statin drug in healthy individuals, and certainly not those with advanced arterial disease.
Comparing the effects of modest homocysteine reduction in people who have already suffered a heart attack is like saying a garden hose is useless in putting out fires because a study showed it is unable to extinguish a raging inferno.
This analogy has more meaning than one might think. Those with severe pre-existing artery disease have already suffered such severe endothelial dysfunction that their arteries have become a raging oxidative and inflammatory inferno.
Therapies (like homocysteine reduction) may have protected against atherosclerosis if initiated early on, but are not by themselves going to extinguish the flames raging in one’s inner arterial lining (the endothelium) after a heart attack.

Homocysteine reduction alone is not the solution for those with advanced atherosclerosis. Life Extension long ago published that those with severe coronary atherosclerosis require aggressive approaches to suppress the 17 independent risk factors known to cause arterial blockage.
Those who rely on Newsweek magazine as a source for health information have been poorly informed in this instance. To read a detailed report exposing the many flaws of the study Newsweek relied on to proclaim that homocysteine reduction yields no benefit, click here.
Life Extension reiterates the critical need for aging individuals to uncover hidden factors (including elevated homocysteine) that are documented to increase heart attack or stroke incidence.
