The Effect of Palatinose Intake on Cognitive Function―A Randomized Double—blind Placebo—controlled Crossover Study―

Objective To investigate the effect of Palatinose on concentration and attention, the present study was conducted on 40 healthy males and females. Method Subjects took the Cognitrax test（which evaluates neurocognitive function）at 60 min pre-ingestion, and 60, 120, and 180 min post-ingestion of 20 g of either Palatinose or glucose. Ten items were scored, including simple and sustained attention, and scores were compared. Result The test results showed that after ingestion of Palatinose, the scores were significantly higher at 60 and 180 min post-ingestion compared with scores after ingestion of glucose, indicating that Palatinose ingestion contributes to maintenance of simple attention for an extended period, and suppresses drowsiness after eating compared to glucose ingestion. The mechanism of action may be that Palatinose is more slowly digested than glucose, resulting in reduced blood glucose fluctuations. Conclusion The results of the present study demonstrated that Palatinose® ingestion helps to maintain attention and concentration, leading to accurate cognitive task responses for an extended period of time（.
