Abstract

Background: Peanuts and tree nuts contain many bioactive compounds that may provide health benefits. There is some evidence to suggest that regular consumption of peanuts and peanut butter may improve cognitive function and mood, however, there are no prior studies examining whether daily intake of dry roasted, skinless peanuts improves cognition. Objective:The objective of this study was to determine the effect of consuming 49 g/day of peanuts for 12 weeks on cognitive function and mental health, compared to consuming a peanut-free diet, among healthy young women. Methods:This was a pre-post test study of 65 women (n = 32 in peanut group, n = 29 in control group). Participants in the peanut group consumed an individually portioned pack of peanuts each day for 12 weeks. Cognitive function was assessed using the CNS Vital Signs computerized neurocognitive test battery. Mental health was assessed using the Depression, Anxiety, and Stress Scale (DASS-42). Differences in endpoints between groups were assessed using ANCOVA tests. Results:There was a significant difference between the two groups in reaction time (6.9 points; p = 0.029), with the control group having a greater increase in scores. There was a significant within-group effect of peanuts on processing speed, with the peanut group increasing scores by 6.3 points (95% CI: 2.7, 9.8). There was no effect of peanut consumption on depression, anxiety, or stress scores. Conclusion:Further research is needed to fully understand the effect of different types of peanut products on cognition. Keywords: cognition, mental health, peanuts, nuts

每日食用花生对健康年轻女性认知功能和心理健康指标的影响
背景:花生和树坚果含有许多可能对健康有益的生物活性化合物。有证据表明,经常食用花生和花生酱可能会改善认知功能和情绪,然而,之前没有研究表明,每天摄入干烤、去皮花生是否能改善认知。目的:本研究的目的是确定在健康的年轻女性中,与不吃花生的饮食相比,连续12周每天吃49克花生对认知功能和心理健康的影响。方法:对65名女性进行前后测试研究(花生组32名,对照组29名)。花生组的参与者在12周内每天食用一包单独分配的花生。使用CNS生命体征计算机化神经认知测试电池评估认知功能。使用抑郁、焦虑和压力量表(DASS-42)评估心理健康。采用ANCOVA检验评估各组间终点的差异。结果:两组在反应时间上差异有统计学意义(6.9分;P = 0.029),对照组得分提高更大。花生对加工速度有显著的组内效应,花生组的得分提高了6.3分(95% CI: 2.7, 9.8)。食用花生对抑郁、焦虑或压力得分没有影响。结论:不同类型花生制品对认知的影响有待进一步研究。关键词:认知,心理健康,花生,坚果
