I heard the 45g figure about ten years ago when my parents were putting
my little sister on a diet. They got a long appointment with a
nutritionist who told them that 45g a day was adequate even if she got
the protein from plant sources, even though she was still growing! Keep
in mind that kids need far more protein than a normal adult who is the
same size. Also, she said that protein complementation is unneccessary.
If you go to the website I mentioned with the list of different foods,
you will see that 45 grams is more than adults need.

That's what I should be telling you.
