Many frugivorous and folivorous nonhuman primates meet their amino acid
requirements by ingesting a variety of leaves. In general, leaves
(especially immature leaves) contain relatively high proportions of
good-quality protein. As we have seen, immature leaves are preferentially
selected by the nonhuman primates studied, and immature leaves are lower in
structural carbohydrates (and often in secondary compounds) than mature
ones.
