THIS WEEK'S TOP STORIES
Nuts and your healthy heart
Eating nuts as part of a healthy diet may be good for your heart. One way nuts may help your heart health is by lowering the low-density lipoprotein (LDL, or "bad") cholesterol level, which plays a major role in the development of plaque that builds up on the blood vessels. Eating more nuts also has been linked to lower levels of inflammation linked to heart disease. And they're a great snack food — easy to store and easy to pack when you're on the go. See how adding them to your diet may help your heart.
DHEA: Evidence for anti-aging claims is weak
A synthetic version of the hormone dehydroepiandrosterone, also known as DHEA, often is touted as an anti-aging therapy. It is used to ward off chronic illness and improve physical performance.

There are concerns that using DHEA as a supplement might increase the risk of hormone-sensitive cancers, including prostate, breast and ovarian cancers. Here's what you need to know.
