Recommendations — To reach these recommended protein intake
totals, whether
total grams or a
percentage of total calories, eat
small, frequent meals containing lean proteins, supplement with protein shakes.
The brain like every other human tissue is made up
of and utilizes protein, so we do have to eat enough protein while the brain is growing and a
small amount for daily operation, but the major metabolic price
of our larger brains is the large increase in the
percentage of total calories used by our brains compared to animals with
smaller brain to body weight ratio.
