来自英国赫尔大学的研究人员发现,大豆中含有丰富的蛋白质和异黄酮,多食用大豆可有效防止绝经后女性骨质疏松及骨质疏松症的发生,该研究结果将于本周在爱丁堡举行的内分泌学年会上展示。


绝经后的女性因雌激素的产生较少,故骨质流失的速度很快,而大豆中含有的异黄酮具有和雌激素类似的化学结构,所以科学家们推测异黄酮或可像雌激素一样防止骨质的流失。

该研究纳入了200名处于绝经后早期的女性,随机分为两组。A组女性每日食用30g的大豆蛋白,含有66 mg的异黄酮;B组女性每日食用同等量的不含异黄酮的大豆蛋白。持续时间为6个月,之后研究人员采集了所有研究对象的血液样本以测量βCTX蛋白的含量。

结果表明,每日食用含有异黄酮大豆蛋白的女性其血液中βCTX蛋白的含量明显低于每日食用不含异黄酮大豆蛋白的女性。这表明A组女性骨质流失的程度较低,因而患骨质疏松症的风险较低。

研究人员还指出,食用含异黄酮大豆蛋白的女性其心血管疾病发生的危险标志物同样也得到了改善。

该研究作者Dr. Thozhukat Sathyapalan说道:

“我们发现,食用大豆蛋白以及异黄酮来预防更年期女性骨质疏松症的发生是安全有效的。东方饮食中含有大豆类的食物较多,每日摄入66 mg的异黄酮符合东方人的饮食习惯,而对于西方饮食来说,每日仅能摄入2-16 mg的异黄酮。”

Dr. Sathyapalan建议西方饮食中应补充异黄酮,这或可显著降低更年期女性骨质疏松症的发生。目前,Dr. Sathyapalan及其同事正计划研究大豆蛋白和异黄酮补充剂对机体的长期影响,探究它们是否可带来其他的健康益处。
