New Study Suggests Concord Grape Juice May Provide Protection Against Breast Cancer
Every three minutes,
a woman in the United States is diagnosed with breast cancer(1). While
factors like age and heredity contribute significantly to a woman's
likelihood of contracting this disease, lifestyle and nutrition choices may
also play a role. One dietary choice that may help provide protection
against breast cancer is a glass of 100 percent grape juice made from deep
purple Concord grapes.
According to a new study, published in the current issue of the Journal
of Medicinal Foods, natural compounds in Concord grape juice protected
healthy human breast cells from DNA damage. Healthy human breast cells were
exposed in a test tube to an environmental carcinogen, benzo(a)pyrene, that
is able to initiate a chain of events leading to breast cancer. However,
the introduction of Concord grape juice compounds blocked the connection of
the carcinogen to the DNA of the healthy cells.
"The purple grape compounds demonstrated the capacity to inhibit DNA
adduct formation as well as to increase the activity of enzymes that
metabolize and detoxify carcinogens, and suppress potentially
cancer-causing oxidative stress," said Dr. Keith Singletary, nutrition
professor and lead researcher at the University of Illinois. "These new
data suggest that anthocyanins present in Concord grape juice, as well as
some other fruits and juices, warrant further study for their breast cancer
chemopreventive potential."
This research is the latest to suggest that Concord grape juice may be
of value in maintaining breast health by suppressing oxidative stress and
inhibiting DNA damage to cells that can lead to the initiation of cancer,
or in helping to slow the progression of breast cancer by slowing the
multiplication of cancer cells. Diets high in natural antioxidants have
been associated with a reduced the risk of some types of cancers, and
Welch's 100% Grape Juice made from Concord grapes is particularly high in
anthocyanins, potent natural antioxidants that give the juice its
characteristic deep purple color.
At the same time, drinking Concord grape juice can be good for the
heart -- much like red wine. And so, with the link between alcohol
consumption and breast cancer causing concern for some women, drinking 100
percent grape juice made from Concord grapes can help your heart and
perhaps your breast health.
Welch Foods Inc. is committed to supporting independent research
exploring the role of Concord grape juice in a healthy lifestyle, and
provided the Concord grape juice compounds for this study.
