Protein RDA underestimated?

[ScottishOatEater]

Hi jeff. I'm wondering, if you have the time, what you think about this well sourced article? It seems there is a lot of recent research that is suggesting that the optimal protein intake may be substantial more than the current RDA suggests.

It was quite convincing for me, that we should be aiming for more than the current RDA. I have little experience in interpreting studies, however, and would love to hear your expert opinion on the research.

I don't respond to these online articles.

I have written extensively on protein, including 6 articles directly addressing how much is enough, and showing, that even when the issues of bioavailability, etc are considered, we easily get in more then enough, while easily surpassing the RDA.

It is a non issue. If anything, longevity research is looking at restricting protein and possibly a few amino acids.

PS A few years ago when the IOM and FNB were weighing in on the new food label, they said that having to list Protein was voluntary/optional because they considered protein a non-issue and that it "is not a public health concern."
