Don't you just love knowing what's new in research. I really enjoyed reading my latest issue of Vegetarian Nutrition and wanted to share some great research with you. Enjoy!
Evidence that protein requirements have been significantly underestimated
Elango, R., Humayun, M.A., Ball, R.O., Pencharz, P.B., Curr Opin Clin NUtr Metab Care. 2010; 13: 52-7
Researches associated with FAO/WHO reviewed recent evidence suggesting that protein requirements in adults have been underestimated. The current DRI recommendations for mean and population safe intakes of .66 and .8g/kg/d respectively of high quality protein in adults are based on a meta-analysis of nitrogen balance studies using single linear regression analysis. When the data were reanalyzed using two-phase linear regression analysis, mean and safe protein requirements were estimated to be .91 and .99 g/kg/d respectively. The two phase linear regression analysis is considered more appropriate for biological analysis of dose-response curves. In addition to this analysis, when an alternative method, the indicator amino acid oxidation technique, was used to determine protein requirements, the mean and population safe requirements in adult men were determined to be .93 and 1.2 g/kg/d which are 41 and 50% higher, respectively, than the current DRI. Consequently, the authors of this research suggested that there is an urgent need to reassess adult dietary protein intake recommendations.

I feel so much better when I eat lots of lean protein.
Wow, that's really interesting... thanks for sharing! Do you still get that level of protein as a vegetarian? I suppose the protein shakes help a lot! I switched from veg to meat when I started training, just for this reason.
really interesting....i've significantly increased my daily amounts of lean protein over the past year, and it's made a huge difference in how i feel!
Hahaha. I'm not surprised in the least. That's science for ya' - we always mix things up or reanalyze after years of research to find we were wrong originally.
I'm sure in another decade they'll find it's really something different as well. I've never really stuck to any strict guideline.
But thanks for sharing all the same. It's nice to know they're still working on fine tuning the details of the "recommended diet."
I agree. I saw a nutritionist last year that was a body builder, but was obviously a qualified nutritionist, I was a little leary of the protein intake but in the end it worked and felt completely different training last year than prior!
