Short-Term New Zealand 'Blackadder' Blackcurrant Juice Supplementation Improves Learning and Memory in Young Adult Rats.

ABSTRACT: Berryfruit consumption has been shown to improve aspects of cognition in humans, and may protect against age-related cognitive decline via antioxidant mechanisms. This study investigated whether short-term supplementation with New Zealand 'Blackadder' blackcurrant (BC) juice supports spatial learning and memory in healthy young adult Sprague Dawley rats. Male rats (n = 24) received BC juice (n = 12; 5.4 mg/kg polyphenols) or a sugar-matched placebo (n = 12) prior to each daily trial during a four-day Morris Water Maze (MWM) acquisition phase and a probe trial on day five. BC supplementation significantly reduced cumulative distance (p = 0.020) and latency (p = 0.030) to the platform. In the probe trial, the trends showed that BC-supplemented rats spent mo
