Is Cardiac Health All in Your Genes?

The good news: Healthy behaviour appears to slash the risk of coronary disease in people at high genetic risk for events. The bad news: Folks with “good genes” cant expect their genetic makeup to offset bad habits, warns a senior cardiologist here.

Pomegranate compound ‘could combat’ complications of ageing

“Pomegranates slow down the ageing process by prompting cells to recycle and rebuild themselves, a study shows,” The Daily Telegraph reports. But before you rush to stock up on the “food of the gods”, the study in question only involved worms and rodents. Compounds called urolithins are produced by bacteria in the gut when breaking down food such as pomegranates, nuts and berries. The researchers found that one of them in particular, urolithin A, increased the lifespan of roundworms by a half. They also improved muscle function in rodents (specifically,…
