Caloric Restriction and Lifespan – Without the Caloric Restriction?. In the Pipeline:

One of my favorite blogs, In The Pipeline deals with the pharma industry and often talks about interesting discoveries. He has a very nice write up on a research paper published in the journal Nature. In that paper, the authors looked at the effect of calorie restriction on lifespan and fertility in fruit flies. This has been done in the past, but the interesting thing is that they started adding back nutrients to their diets to see what the effect was. The conclusions are very interesting, in that adding carbs did not affect lifespan, but that adding methionine (one of the essential amino acids) had a more significant effect than adding anything else.
Now, Don’t go out and start overeating carbohydrates… those are still things to keep in check for diabetes/etc., but it is likely that you will see reformulations of supplements to include less methionine and other amino acids. Very cool stuff, good to keep an eye out for…
