(NaturalNews) Birds such as sparrows, thrushes and warblers are
apparently experts on preventing disease and optimizing their bodies to
deal with stress. If that sounds like an exaggeration, consider this:
scientists at the University of Rhode Island (URI) have discovered these
migratory birds eat certain nutrient-packed berries instead of their
usual diet of bugs at certain times of the year. Why would this change
in eating habits be beneficial? It turns out, according to the URI
researchers, that the superfood fruit the birds eat offers protection
against oxidative stress that occurs during long flights. This news is
important because oxidative stress is known to trigger inflammation and a
host of serious diseases -- in both birds and humans.
The new
research, recently announced at the American Chemical Society's 239th
national meeting held last month in San Francisco, revealed that birds
stopping over on Block Island specifically go after arrow-wood berries
which contain more anti-oxidants and pigments than the 11 other berries
that grow on the island. That means the migratory birds somehow know to
specifically zero in on arrow-wood berries, the richest source of
nutrients in the area.
Navindra Seeram, assistant professor of
pharmacy and head of the Bioactive Botanical Research Laboratory at URI,
and Scott McWilliams, a URI professor of wildlife ecology and
physiology who has studied migratory birds for over a decade, are
researching migratory birds' eating habits to see how this knowledge
could help human health. The two teamed up after McWilliams learned that
Seeram was researching oxidative stress and inflammation and the
effects berry fruits can have on reducing those disease-linked problems
in people. Anti-oxidants found in berries are believed to play an
important role in preventing cancer and other serious diseases.
Working
with URI graduate student Jessica Bolser and post-doctoral researcher
Liya Li, Seeram and McWilliams spent months on Block Island carefully
observing what the birds' ate, collecting samples of 12 different kinds
of berries, and analyzing the berries to document their anti-oxidant
content. They found that migratory birds eat the arrow-wood berries,
digest them and defecate the seeds over wide areas, thereby ensuring the
survival of the plants.
"We're suggesting that birds choose
deeply colored berry fruits in part because of their anti-oxidant
properties...the birds are attracted to the berries because of their
rich color, which we believe is a plant's response to the stress of
constant exposure to the sun and other stresses," Seeram said in a
statement to the media. "It's a partnership that benefits plant and
bird."
The URI research is expected to help bird conservation
efforts because the findings could play a critical role in habitat
protection for migratory birds. It could also be a boon to human health,
guiding humans to locate nutrient-dense superfood berries by,
literally, going to the birds to see what they eat to in order to cope
with physical stress.
As NaturalNews has previously reported, a
variety of berries are being studied by scientists for their
health-building properties. For example, purple berries such as
blueberries and acai contain antioxidants called anthocyanins that have
been shown to protect the heart and vision, promote mental focus, and
prevent oxidative stress (
