科学家最近发现西瓜中富含扩张血管的化合物—— L-瓜氨酸,可以减少心肌梗塞和中
风的危险。研究发现每日喝一定量的西瓜汁可以使高血压病人的血压下降[注]。
英国有160万人患有高血压,使心梗和中风的死亡率双倍地增加。英国人每年死于心梗
和中风者达6万以上。
一氧化氮是能使血管内皮扩张的重要物质,西瓜种的L-瓜氨酸可以使血液中的一氧化氮
含量明显增加。美国科学家给患高血压的自愿者每日6克从西瓜种提取出的L-瓜氨酸。6
星期后,9名受试者的血压均有下降,而且无副作用。但是如果是吃西瓜,大约一个半
西瓜才可达到这种治疗剂量。
佛罗里达州立大学的Arturo Figueroa博士说:这项研究说明保健食品有扩血管作用,
有一些食物可以防止高血压的发生,从而避免心梗和中风。虽然研究刚刚开始,结果令
人鼓舞,为今后在更多的人群中研究打下了坚实的基础。
研究人员之一Bahram Arjmandi教授说:所谓保健食品是指那些能促进健康、或防止疾

ingredients.
After some trial and error I now mix my own pre-workouts, kinda. I typically
use half dosage of whatever pre-workout I am currently using and then mix
in "Beta Alanine" and "Citrulline Malate", which I found u... 阅读全帖
