动物实验记录了葡萄汁对认知表现和运动技能的影响，对人类的观察研究表明类黄酮摄入量与认知能力下降之间存在负相关。这些作用可能与多酚的抗氧化特性有关。果汁消耗和类黄酮摄入也可能影响食欲。研究在嗜睡增加（午餐后低迷）期间饮用葡萄汁对食欲、情绪和内隐记忆的急性影响。该研究包括 35 名平均年龄为 26 岁的参与者，他们平均每天吸 11 支香烟，持续 8 年。它包括一次练习和两次治疗。所有课程都涉及在午餐时饮用葡萄汁或能量匹配的安慰剂，然后评估情绪、内隐记忆、食欲和食物摄入量。两种治疗的情绪随着时间的推移而下降，但午餐后葡萄汁和安慰剂之间在任何方面都没有差异。这项研究没有记录饮用葡萄汁对吸烟者情绪、内隐记忆、食欲或食物摄入量的任何急性影响。
Animal experiments document effects of grape juice on cognitive performance and motor skills, and observational studies in humans suggest an inverse association between flavonoid intake and cognitive decline. These effects may be related to the antioxidant properties of polyphenols. Juice consumption and flavonoid intake may also affect appetite. To study the acute effects of grape juice consumption on appetite, mood and implicit memory during a time of increased lethargy – the post-lunch dip. Thirty-five participants with a mean age of 26 years who smoked a mean of 11 cigarettes/day for 8 years were included in the study. It included a practice session and two treatment sessions. All sessions involved consumption of grape juice or an energy-matched placebo with lunch followed by assessments of mood, implicit memory, appetite and food intake. Mood decreased over time for both treatments, but there were no differences after lunch between grape juice and placebo for any measure. This study did not document any acute effects of grape juice consumption on mood, implicit memory, appetite or food intake in smokers.
