市面上的油是怎么分类的 刘敏 中南大学湘雅三医院
现在食用油的种类非常多，我们可以把这些油总结为三支队伍，首先是以大豆油、葵花籽油为主的多不饱和脂肪酸队伍，也是我们讲的MUFA--ω-6、亚油酸类；第二队是以橄榄油、茶油为代表的单不饱和脂肪酸油，也是我们讲的ω-9、油酸队；第三大类是以亚麻籽酸（油）、红花、紫苏油为代表的ω-3，即亚麻酸队。这三支队伍里的油对人体而言都是不可缺少的，普通人应该要按照自己的膳食习惯，在一段时间之内轮换的使用各种油。一般建议厨房的灶台上要放三瓶油，一瓶就是MUFA，也是多不饱和脂肪酸为代表的大豆油、葵花籽油，另外要放一瓶以PUFA，也是单不饱和脂肪酸为主的橄榄油、茶油，还要放一瓶菜籽油、花生油，那么这三瓶油要轮着用，可以这一个菜用葵花籽油，下一个菜用茶油，也可以在时间上换着用，如这一个礼拜用玉米油，那下一个礼拜用大豆油，这样每一种油都有摄入，每一种油我们都有需要。
