Studies have shown that supplementation with extracts from various sources, including fruits and vegetables reverse the age-related changes in movement and cognition. We hypothesized that these beneficial effects result from the presence of anti-oxidants and anti-inflammatory compounds in the fruits and vegetables that contribute to reduced oxidative stress, inflammation and cell death while potentially enhancing neurogenesis. The present study was performed to determine the impact of supplementation with GrandFusion(GF) to aged Fisher 344 rats for 4 months to determine the impact on attenuation or reversal of the age-related deficits. When the aged rats consumed a diet enriched with the extracts the results showed an improved motor performance, and enhanced cognitive functions. In addition, the rats showed reduced oxidative stress and inflammation, and enhanced neurogenesis, Nrf2 and anti-oxidant expression. The effect of GF extracts on the augmentation of memory and learning is significant and may function through the modulation of antioxidant enzymes, signaling pathways and additional mechanisms to improve the aging process. These studies further support the recommendation of USDA for the consumption of fruits and vegetables to improve healthy aging.
研究表明,补充包括水果和蔬菜在内的各种来源的提取物可逆转与年龄相关的运动和认知变化。我们假设,这些有益效果源于水果和蔬菜中存在的抗氧化剂和抗炎化合物,它们有助于减轻氧化应激、炎症和细胞死亡,同时可能增强神经发生。本研究旨在确定对老年费希尔344大鼠补充GrandFusion(GF)4个月的影响,以确定对减轻或逆转与年龄相关缺陷的影响。当老年大鼠食用富含提取物的饮食时,结果显示运动性能得到改善,认知功能增强。此外,大鼠表现出氧化应激和炎症减轻,神经发生、Nrf2和抗氧化剂表达增强。GF提取物对增强记忆和学习的作用显著,可能通过调节抗氧化酶、信号通路和其他机制来改善衰老过程。这些研究进一步支持了美国农业部关于食用水果和蔬菜以促进健康衰老的建议。
