Arthritis Rheum:西兰花可有效预防关节炎

2013-09-03 刘海英 中国科技网

英国东英吉利大学最新一项研究发现,萝卜硫素对于关节软骨损伤具有很好的预防和缓解作用,经常食用如西兰花等富含该种化合物的食物,或可有效预防骨关节炎。 研究人员发现,萝卜硫素能够抑制一种导致炎症的关键分子,阻断引起关节损伤的酶。实验表明,给小鼠喂食富含萝卜硫素的食物,可有效减少小鼠的软骨损伤,相比于那些没有喂食这类食物的小鼠,它们患上骨关节炎的几率明显降低。研究人员观察了萝卜硫素对人类软骨细

研究人员发现,萝卜硫素能够抑制一种导致炎症的关键分子,阻断引起关节损伤的酶。实验表明,给小鼠喂食富含萝卜硫素的食物,可有效减少小鼠的软骨损伤,相比于那些没有喂食这类食物的小鼠,它们患上骨关节炎的几率明显降低。研究人员观察了萝卜硫素对人类软骨细胞和牛的软骨组织的影响,同样证明了这种化合物具有减缓软骨损伤的功用。

萝卜硫素是十字花科蔬菜中富含的一种化合物,如球芽甘蓝、卷心菜,都含有丰富的萝卜硫素,而西兰花则是萝卜硫素含量最丰富的一种蔬菜。过去有研究表明,这种化合物具有抗癌、消炎作用,但此次则是首次研究这种化合物对关节健康的作用。

研究人员表示,软骨细胞、软骨组织以及小鼠这三种实验模型都表明了萝卜硫素有助于软骨健康,这意味着食疗或许是一种预防和减缓骨关节炎的有效方法。无论是对于关节炎患者还是健康人士来说,经常食用西兰花等富含萝卜硫素的食物,都将是一个很好的选择。
