And L-Histidine is essential for children.
But I'm thinking, does the body need an absolute amount of protein everyday
or an absolute ratio?
If your body needs a fixed amount everyday, like 2.5 grams of methionine,
then you could just eats of lots of soy and you'd surely get or exceed the
minimum requirement of all the proteins. But through excess, you'd
overtax your kidneys in getting rid of the nitrogen.
If your body needs a fixed ratio everyday, like lysine/methionine should
be 3.8 even though amount of methionine may be 1.5 or 2.5 or 3.5 grams,
then no amount of soy will satisfy the requirement.
