西兰花这样吃最抗癌

　西兰花是公认的抗癌明星，但怎么烹调才能将抗癌功效最大化呢？美国伊利诺伊大学科学家研究发现，烹调西兰花最好的方法是，将其隔水蒸5分钟。当西兰花变成亮绿色的时候，其抗癌作用最强。

　　研究人员指出，西兰花是天然抗癌化合物——萝卜硫素的极佳食物来源，其中的黑芥子酶对萝卜硫素的抗癌作用极为关键。一旦黑芥子酶遭到破坏，萝卜硫素也就没有抗癌作用了。因此跟其他烹调方法相比，西兰花隔水蒸5分钟左右，黑芥子酶保持得最好，这样做出来的西兰花更抗癌。

　　对此，济南大学营养学副教授綦翠华还建议，烹调西兰花时宜剪不宜切。整朵的西兰花花簇由许多小粒的花朵构成，如果直接放在案板上切，会有很多小粒花朵散落，造成损失。建议将西兰花冲洗后，用剪刀从花簇的根部连接处剪下一个个花簇，或者用手直接掰下，这样能得到完整的花簇。此外，还有研究发现，西兰花和番茄一起吃，防癌效果会更强。
