The study, which was published in the Journal of Endocrinology,  looks at in-vitro cell lines from mice and rats.

The experiment showed that the supplement triggers a mechanism intended to lower high blood sugar levels, but it also destroyed about 50 per cent of the cells by affecting SIRT1, a protein crucial to cell survival.

Granola bars are great for a quick snack, but they're not all the same.

Granola bars are great for a quick, convenient snack.  Be sure to read the Nutrition Facts label to choose a bar that contains some protein and fiber, which will help you stay full longer.

Businessweek.com is reporting on a new study that suggests that running a marathon can damage your heart, with more than half of the segments in the heart's main pumping chamber typically functioning a little under par during the race. The good news is that other parts of the heart pick up the slack and the changes reverse within three months or fewer after the run, the researchers found.

The end result is that the study shows that the more fit and trained a runner is, the less effect the strain of a marathon was found to have on the heart.
