NIH Research Matters for March 26, 2012—risk in red meat, carnivores lack taste for sweets, and worms yield insights into brain development

By Newsroom America Feeds at 26 Mar 2012

The March 26, 2012, "NIH Research Matters" is now available In this week's edition:

*Risk in Red Meat?* Photo of a woman looking at a package of meat at the grocery store new study adds to the evidence that eating red meat on a regular basis may shorten your lifespan. The findings suggest that meat eaters might help improve their health by substituting other foods for some of the red meat they eat.

*Carnivores Lack Taste for Sweets* Photo of cat-like fossa. meat-eating mammals have lost their ability to taste sweetness, and those that swallow their food whole may lack bitter and savory tastes. The new findings suggest that unneeded taste receptors might be lost through evolution.

*Worms Yield Insights into Brain Development* Microscope image showing a two-colored pattern in an acorn worm embryo. worm embryos don't have anything resembling a human brain. But a new study in these worms found ancient evolutionary origins for our own complex central nervous system and brain.

*Editor's Picks from past issues:*
