Consuming Concord grape juice daily may enhance memory in older people with mild impairment of brain function.
Concord grape juice contains polyphenols, compounds that confer antioxidant and anti-inflammatory properties and influence neuronal signalling. In that previous studies have shown that Concord grape juice supplementation reduce inflammations, blood pressure and vascular pathology in individuals with cardiovascular disease, Robert Krikorian , from University of Cincinnati Academic Health Center (Ohio, USA), and colleagues studied a group of twelve older adults with memory decline, but not dementia. Subjects consumed Concord grape juice for 12 weeks. Observing “significant improvement in a measure of verbal learning and non-significant enhancement of verbal and spatial recall,” they suggest that: “supplementation with Concord grape juice may enhance cognitive function for older adults with early memory decline.”
