Grape juice is a fruit juice obtained from crushing grapes. The juice is often fermented and made into wine, brandy, or vinegar. In the wine industry grape juice which contains 7-23 percent of pulp, skins, stems and seeds, is often referred to as “must.” Grape juice can also be sweetened and preserved as a non-alcoholic drink beverage. Drinking Concord grape juice can be good for the heart – much like red wine.

In the wine industry grape juice which contains 7-23 percent of pulp, skins, stems and seeds, is often referred to as “must.” Grape juice can also be sweetened and preserved as a non-alcoholic drink beverage.
Commercial grape juice and grape juice drinks contain preservatives and coloring, and sometimes vitamins. Like wine, grape juice also contains antioxidants such as flavonoids, providing some health benefits. These antioxidants have been proven beneficial to the skin.Typically, purple grape juice is made from concord grapes.
Benefits of Grape Juice.
A recent study published in the Journal of Agriculture and Food Chemistry found that grape juice was among the highest in antioxidants among the juices tested, including pomegranate juice. Care should be taken when drawing conclusions from these results, since the pomegranate juice used was only a 30% pomegranate juice blend — 30% pomegranate juice diluted with sugar water and other lower-antioxidant juices.
French scientists claim grape juice can have the same protective effect as red wine. Dr. Valeriea Schini-Kerth is leading a study in Cardiovascular Research, states that grape juice shows the same effects as red wine, which is a very important discovery.
Researchers at Strasbourg Louis Pasteur University undertook experiments on the juice of red grapes with large seeds.
Red wine and certain types of grape juices have high levels of polyfenol which can stop the production of proteins causing cardiovascular illnesses.
Schini-Kerth states that not every grape juice has the same effect, but those containing polyfenol can be effective.
Grape Juice Protect against Breast Cancer
Every 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.
Benefits of Grape Juice for Heart
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.
Grapes, like nuts, seeds, some vegetables and fruits, contain flavonoids – interesting substances that are also found in red wine and act as antioxidants. The investigators studied twelve men and three women, average age 62 years, who had known coronary heart disease. They were asked to drink Welch’s 100% Concord Grapes for fourteen days – about 21 ounces or two-thirds of a quart a day. Studies were then made of the diameter of an artery in the arm and the ability of low-density lipoprotein cholesterol (LDL, so called bad cholesterol) to be oxidized, a step thought to be important for LDL to get into blood vessel walls and cause arteriosclerosis.
The results showed that, after the grape juice diet, the blood vessels showed a greater ability to dilate and the LDL was more resistant to oxidation, both reactions likely to reduce the risk of coronary heart disease and heart attacks.
Grape juice can also lower the risk of developing the blood clots that lead to heart attacks, according to unpublished findings from Georgetown University researcher Jane Freedman, M.D. So can red wine, but in this case grape juice is the more practical way to go: “Wine only prevents blood from clotting (when it’s consumed) at levels high enough to declare someone legally drunk,” says University of Wisconsin researcher John Folts, Ph.D. “With grape juice, you can drink enough to get the benefit without worrying about becoming intoxicated.”
With a glass of purple grape juice with breakfast or for an afternoon snack, her heart can realize the same benefits as those of her wine-drinking friends. And if you don’t want wine at dinner, uncork one of the fine nonalcoholic reds on the market. They’re loaded with antioxidants as well as great flavor and you can drink all you like without worrying about driving home.
