Novel research links an aging gut microbiome with heart disease

Rich Haridy March 19, 2019

A new study suggests an aging gut microbiome may be somewhat responsible for the degradation in cardiovascular heath that tends to appear as we grow older. The study is yet another addition to the growing body of evidence affirming the role gut bacteria plays in age-related disease.

lder mice were found to have less diverse microbial populations that over-produce certain compounds that could ...

Trial concludes vitamin D and fish oil don't lower incidences of heart disease or cancer

Rich Haridy November 12, 2018

The results of one of the largest placebo-controlled trials into the beneficial effects of vitamin D and fish oil ever conducted are out and, despite some hyperbolic media releases, found both supplements were no better than the placebo in lowering incidences of cancer or cardiovascular events.

Both omega-3 fish oil and vitamin D supplements have been found to be no better than ...

Harvard's artificial heart parts beat like the real thing

Michael Irving July 23, 2018

It's difficult to study how the heart reacts to diseases and medications. Researchers at Harvard have now grown a model of a human left ventricle that spontaneously beats, marking a substantial step towards engineering entire hearts for more accurate testing of new treatments.

Comprehensive study concludes omega-3 fish oil supplements don't reduce risk of heart disease

Rich Haridy July 17, 2018

A large-scale meta-analysis collecting data from 79 trials has concluded that omega-3 supplements have little to no effect in preventing heart disease, stroke or death. The results contrast the common belief that omega-3 supplements confer a variety of beneficial cardiovascular protections.

A massive study has found omega-3 supplements confer little to no beneficial protective effect against heart ...
