膳食补充剂可以改善心脏健康,延长预期寿命

膳食干预可以有益于肌肉萎缩症的人的心脏健康。这是在实验生理学发表的新研究。如果这些发现在人类中得到证实,可能意味着现成的补充剂可以改善健康和延长预期寿命。

膳食干预可以有益于肌肉萎缩症的人的心脏健康。这是在实验生理学发表的新研究。如果这些发现在人类中得到证实,可能意味着现成的补充剂可以改善健康和延长预期寿命。

来自爱荷华州立大学,奥本大学和美国蒙大拿大学的科学家发现,用槲皮素(在许多水果,蔬菜,叶子和谷物中发现的黄酮醇)补充小鼠的食物改善了生物医学结果,提供了炎症和抗氧化作用。令人惊讶的是,他们还发现槲皮素喂养的小鼠比对照组更有活性。

杜兴氏肌营养不良(DMD)是一种严重类型的肌营养不良,其导致心脏健康的下降,过早死亡,平均年龄为26岁。杜兴氏肌营养不良主要影响男性。

研究人员使用几个肌营养不良的小鼠模型,并行进行实验。通过这样,他们能够在人类中尽可能接近地复制肌营养不良。

相应的作者John C. Quindry博士说:“目前可用的饮食干预可以使那些肌营养不良患者受益,我们给小鼠一个槲皮素剂量,与可以给予人类的槲皮素剂量成正比,这是动物和人类研究结果之间的最佳连接”。
