Elchanan writes: --- The quantities of protein found in fruits and tender

greens are perfect for our species, after weaning, about 5-6% of total

calories, perhaps even a bit less. More than this is toxic.

 

Chase responds:

NO, more than that is optimal, actually!! In this page it shows that

domesticated fruit

averages 5.5% protein, while wild fruit averages 9.5% protein. Since

cultivated fruit is NOT

what we evolved on, it's safe to say that this is not the amount that we're

adapted too- in

fact it's too little in the long run.

Quoting from the text at the foregoing link:

 

Dietary crude protein (CP) content showed one of the

more dramatic differences between the monkey (with

an annual average around 15% CP) and chimpanzee

diets (annual average 9.5% CP) (Figure 10). There were

no significant differences among the monkeys but the

difference between the chimpanzees and the monkeys

was significant. There was no significant seasonal

\ variation. As a point of reference, adult humans need

only about 9.5% protein on a dry matter basis (RDA, 1980),

so the chimpanzees' plant diet was probably not deficient

in protein, simply lower in content than the monkeys.

 

The RDA number cited is from 1980 and is obsolete. But what we do know is

that, as brain activity/intelligence increases, there is a marked movement

toward significantly higher sugar requirement, to sustain the added brain

activity. This concept is well-understood among students of comparative

anatomy.

 

In the foregoing paragraph, we see evidence of this trend: the monkeys, all

of similar intelligence and brain activity level, average around 15%

protein, the chimpanzees, of higher intelligence and therefore greater brain

activity level, about 9.5%, i.e., higher percent of sugar. The chimpanzees

are far closer to humans in intelligence, overall genetics, and in many

other ways than the three other monkey species observed in this study.

Humans need even less protein than do the monkeys, our bodies/lean tissue

are not nearly as strong or robust, therefore our protein requirement is

lower. At the same time, our brain activity is considerably higher, hence

the greater need for fuel (sugar).

 

Best to all,

Elchanan
