经常食用蓝莓和草莓的人群脑力衰老的平均速度较之其他人慢2.5年4
逆转因衰老而减弱的大脑运动协调功能5
提高记忆力6
持续服用蓝莓汁的老年人的早期记忆衰退症状得到有效缓解,记忆力有了突出改善7
饮用蓝莓汁的儿童综合认知能力更强,尤其在记忆力和集中注意力上。脑力测试的结果也表明,高浓度的蓝莓汁和饮用后3-6小时间的效果最好8
虽然科学家还没确定每天该摄入多少花青素,但就目前研究结果来看,短期/长期食用蓝莓可以促进大脑功能,尤其在改善记忆力方面。
蓝莓富含黄酮类化合物,与心脑血管疾病发病率呈负相关9
蓝莓能有效降低血压、提高动脉收缩与舒张能力以及减小血液中胆固醇浓度10
初步显示,蓝莓对人体血管舒张和收缩有益,且能帮助降压9
蓝莓提取物能抑制癌细胞繁殖、促使细胞凋亡、延缓肿瘤触诊、减小肿瘤扩散11
