防癌大功臣 綠花椰排名第一
作者： 華人健康網 記者羅詩樺／編譯 | 華人健康網 – 2012年11月30日 下午12:02為什麼花椰菜能抗癌？
癌症的起因是由於體內DNA受到外物的侵襲，例如病毒、輻射線等，其中有一種是受到自由基傷害而造成的癌症。天然的抗氧化物例如植化素可以減少體內的自由基，因而降低致癌機率。而花椰菜中正富含豐富的植化素，因此抗癌能力也很強。
含類黃酮益處多
類黃酮的角色在於能使維生素C與腎上腺素不被銅氧化，也可以幫助產生抗自由基的酵素，防止血小板凝結作用，是最好的血管清理劑，而花椰菜中的檞皮素（Quercetin）就是類黃酮的主要來源，因此可以抑制致癌物發生作用。
根據臨床研究，蘿蔔硫素（sulforophane）可以抑制幽門螺旋桿菌的生長。因此胃潰瘍的人可以考慮補充:

"Dietary sulforaphane-rich broccoli sprouts reduce colonization and attenuate gastritis in Helicobacter pylori–infected mice and humans". Cancer Prev. Res. 2 (4): 353–360. doi:10.1158/1940-6207.CAPR-08-0192. PMID 19349290. Lay summary.

動脈硬化其實也有研究證實蘿蔔硫素（sulforophane）可以抑制發炎，協助病情改善:

至於癌症的研究不少，尤其是乳癌跟皮膚炎的預防，有興趣可以參閱:

不只是女性癌症，男性的前列腺癌也有研究發現可以幫助抑制癌症細胞生長:

至於檞皮素（Quercetin），研究也發現可以抗病毒(包含B肝病毒以及愛滋病毒)、抗發炎、抗癌甚至改善纖維肌痛症等等，好處列舉不完:

建議大家平常可以多攝取綠花椰菜來保健，不過要達到上述研究治療效果，必須是萃取單方的高劑量補充品才能達到，提醒大家留意。
