Our previous observations concerning the chemical composition
and bioactivity in vitro of quinoa leaves (QL) fill this gap and
open new perspectives for their introduction into the normal diet,
at least as supplements. The high bioavailability of bioactive QL
compounds, parallelled by their in vitro effects on prostate cancer
cells, suggests that they can help in the chemoprevention of cancer
and other diseases related to oxidative stress, such as atherosclerosis.
