New study suggests Concord grape juice may provide protection against breast cancer
August 10, 2007Every three minutes, a woman in the United States is diagnosed with breast cancer . 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 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.

Breast Cancer News and Current Breast Cancer Events RSSM. D. Anderson study finds change in HER2 status after treatment with Herceptin
Researchers at The University of Texas M. D. Anderson Cancer Center have discovered that when treated with Herceptin prior to surgery, 50 percent of HER2 positive, breast cancer patients showed no signs of disease at the time of surgery.
M. D. Anderson study finds racial disparities in radiation therapy rates for breast cancer
Black women are less likely than white women to receive radiation therapy after a lumpectomy, the standard of care for early stage breast cancer, according to a new study by researchers at The University of Texas M. D. Anderson Cancer Center.
New nano device detects immune system cell signaling
Scientists have detected previously unnoticed chemical signals that individual cells in the immune system use to communicate with each other over short distances.
CSHL scientists identify new drug target against virulent type of breast cancer
Tumor cells in a particular subset of breast cancer patients churn out too much of a protein called ErbB2 -- also often called HER2 -- which drives the cells to proliferate unchecked. Patients unlucky enough to be in this group -- about one in four -- have poorer prognoses and clinical outcomes than those who don't.
Dense tissue promotes aggressive cancers
New research may explain why breast cancer tends to be more aggressive in women with denser breast tissue. Breast cancer cells grown in dense, rigid surroundings step up their invasive activities, Vanderbilt-Ingram Cancer Center investigators report in the Sept. 9 issue of Current Biology.
Women exposed to negative life events at greater risk of breast cancer: BGU study
Happiness and optimism may play a role against breast cancer while adverse life events can increase the risk of developing the disease.
Hormone replacement therapy improves sleep, sexuality and joint pain in older women
One of the world's longest and largest trials of hormone replacement therapy (HRT) has found that post-menopausal women on HRT gain significant improvements in quality of life.
Positive thinking may protect against breast cancer
Feelings of happiness and optimism play a positive role against breast cancer. Research published today in the open access journal BMC Cancer suggests that while staying positive has a protective role, adverse life events such as the loss of a parent or close relative, divorce or the loss of a spouse can increase a woman's risk of developing the disease.
Anti-tumor effects are enhanced by inhibiting 2 pathways rather than 1
Two independent research groups have found that simultaneous inhibition of two signaling pathways resulted in substantially enhanced antitumor effects in mouse models of prostate and breast cancer. In an accompany commentary, Steven Grant, at Virginia Commonwealth University Health Science Center, Richmond, discusses the clinical importance of these studies and highlights some of the questions that still need to be answered.
Why a common treatment for prostate cancer ultimately fails
Some of the drugs given to many men during their fight against prostate cancer can actually spur some cancer cells to grow, researchers have found. The findings were published online this week in a pair of papers in the Proceedings of the National Academy of Sciences.
