Muskelmasse vs. BMI for livslengde

[Tronaldo]

Interessant studie som kan tyde på at muskelmasse er en bedre indikator for livslengde enn BMI. http://www.scientificamerican.com/podcast/episode/muscle-mass-beats-bmi-as-longevity-predictor1/

TL;DR:

Researchers analyzed BMI and muscle mass data from more than 3,600 seniors in a long-term study. And they tracked which seniors had died, a decade later. Turns out BMI wasn't much good at predicting chance of death.

But muscle mass was: more muscle meant better odds of survival. The study appears in The American Journal of Medicine. [Preethi Srikanthan and Arun S. Karlamangla, Muscle Mass Index as a Predictor of Longevity in Older-Adults]

There's no cause-and-effect here—just correlation for now.
