The Protective Polyphenol

Polyphenol antioxidants are a particular type of plant nutrient naturally found in fruits, vegetables and plant-derived beverages such as tea, coffee, red wine and our personal favorite, grape juice.

Welch's 100% Grape Juice has higher antioxidant power per serving than other popular 100% fruit juices – more than twice as high as orange juice.11 Welch's 100% Grape Juice made from Concord grapes is a great complement to whole fruits and vegetables, and is a delicious and convenient way to consume more fruit, and in particular, more purple fruit, as part of a balanced diet.

Preliminary research suggests that 100% grape juice made from Concord grapes:

Cardiovascular Health Grapes

Helps protect cardiovascular health.

Helps control the way bad cholesterol may lead to damaging the arteries. Studies have shown that the flavonoid antioxidants in Concord grape juice may help slow the oxidation of LDL cholesterol, or "bad" cholesterol, in the arteries – which may help minimize damaging effects – allowing blood to flow where it's needed and promoting healthy, clear arteries.1,2,3

Encourages flexible arteries. A recent study showed that Concord grape juice works in a similar fashion to red wine in stimulating nitric oxide production in the lining of the arteries - important for greater blood vessel flexibility. 4

Contributes to healthy blood pressure. Because of its positive effect on arterial health, many researchers believe that drinking Concord grape juice contributes to healthy blood pressure. In fact, two preliminary studies showed a reduction in blood pressure in hypertensive patients. 5,6

Memory Grape

May help protect memory and brain health.

May help slow age-related cognitive decline. Study findings published in the March 2006 issue of Nutrition suggest that Concord grape juice may be beneficial in reversing or preventing the effects of aging on short-term memory, coordination, balance and strength. 7

A separate study indicates a link between fruit and vegetable juice consumption and the slowed onset of Alzheimer's disease. Study participants who reported drinking juices at least three times weekly were 76% less likely to develop Alzheimer's disease than those who drank juice less than once a week. 8

Medical Sign

May be protective of long-term health.

According to the U.S. Food and Drug Administration, "diets rich in fruits and vegetables may reduce the risk of some types of cancer and other chronic diseases." Research specific to Concord grape juice in this area is extremely preliminary, but initial studies show promise. A new study published in the Journal of Medicinal Food found that natural compounds in Concord grape juice may help protect healthy human breast cells from DNA damage.9

In this laboratory study, healthy human breast cells were exposed to a chemical substance from our environment that can damage the cells' DNA.

The introduction of Concord grape juice compounds actually blocked the connection between the chemical substance and the DNA of the healthy cells.

Are you getting enough purple in your diet?

Fruits and vegetables with dark skins tend to have high levels of natural antioxidants, and the Concord grape with its deep purple skin fits right in. The Concord grape actually gets its polyphenol antioxidant power from two sources, the deep, dark thick skin and the seeds inside. What protects the Concord grape from the harmful effects of nature basically may protect your healthy cells as well. Interestingly, many people eat fewer purple and blue fruits and vegetables than other color groups.10 With the help of Welch’s 100% Grape Juice, made with Concord grapes, it’s never too late to start getting more purple.
