12-15 While considered a preliminary area of science, researchers have recently found that 100% grape juice made with Concord grapes and fortified with vitamin C increased a type of immune cell – the gamma delta T cell a cell that sends signals to the immune system to respond. The authors did not find statistically significant improvements in improved list retention or spatial memory, but did observe positive trends.Ĭoncord grape juice could contribute to a healthy immune systemĮarly research suggests that certain nutrients (i.e., polyphenols and vitamin C), like those found in Concord grapes, may play a role in supporting a healthy immune system. While there were no statistical differences between the groups at baseline, following the treatment, those consuming Concord grape juice demonstrated significant improvement in list learning. Each subject was assessed with measures of verbal and spatial memory before and after the intervention. *In this investigation, 12 older adults with early memory decline were randomly assigned to consume either 100% Concord grape juice or a calorie-matched placebo beverage for 12 weeks. To learn more about this research and related laboratory studies, visit the Grape Science Center. However, the pilot study is promising because it shows that further research is warranted to learn if Concord grape juice can support healthy cognitive function as we age. 11 This is an emerging area, and results are very preliminary, so more research is needed before drawing any conclusions. A pilot study reported in 2010 found that Concord grape juice may benefit older adults with early memory decline. Scientists are investigating the effects of Concord grapes on heart health and cognitive function. What’s good for the heart may also be good for the mind*
6,7 Specifically, growing research suggests that drinking Concord grape juice can benefit the heart by helping maintain flexible arteries 4,7,8 to support healthy circulation. To learn more about the studies referenced in this section, visit the Grape Science Center.Ĭoncord grape juice has been shown to provide many of the same heart-health benefits of red wine, without the worries of alcohol. Studies suggests that these plant nutrients act as antioxidants to help minimize the damaging effects of LDL or “bad” cholesterol and help support healthy, clear arteries.
In fact the grapes used to make red wine and the Concord grapes used in certain 100% grape juices contain many of the same polyphenols. Ĭoncord grapes make heart-healthy 100% juice:Ĭoncord grapes contain plant nutrients (or phytonutrients) called polyphenols. For more tips to help increase your family’s fruit intake, visit. Concord grapes and 100% grape juice both count as part of the fruit group and can be delicious, colorful additions to the diet. 2 Blue and purple fruits, like the Concord grape, provide health promoting plant nutrients ( polyphenols) that may not be found in other colors of fruits and vegetables. Unfortunately, most of us are not currently meeting these recommended daily amounts 1, especially falling short on blue and purple fruits and vegetables. The USDA’s My Plate recommends that Americans make half their plate fruits and vegetables. Health & Nutrition The Concord Grape - One Super Fruit!
