水果吃法不当会助长肥肉
发布时间:2011-06-21      来源:家庭医生在线

  1、何谓“一份水果”?

  营养师常常以“一份、两份”来形容水果,但“一份”其实又是多少?一份水果等于两个小型水果(奇异果),或一个中型水果(苹果、橙),或半个大型水果(西柚、火龙果)或半杯粒状水果(提子、切粒西瓜),或四分之一杯不含糖和盐的果干。

  2、吃西柚有助燃烧脂肪?

  民间流传西柚含特别成分,有助烧脂。其实这没有根据。有人吃西柚后变瘦,只因以西柚代替了其他热量较高的食物,以其他水果代替也成。西柚的卡路里在水果中并不算低,一个西柚等于半碗饭,只吃西柚也会导致营养不均。

  3、果汁比鲜果更易致肥?

  不少大忙人会以饮果汁代替吃水果,但果汁除了含较少纤维外,卡路里比鲜果多16%至119%,糖分多9%至103%。

  因为在榨汁过程中糖分会自果肉中被挤压出来,变得更易吸收。所以饮果汁应选没额外加糖的,最好连有果肉,每日饮用不要超过一大杯。

  4、所有水果都是低脂的,是瘦身佳品?

  牛油果、椰子和榴莲3种水果其实是减肥大敌,与苹果每100克含60卡路里相比,相同分量的牛油果含180卡路里、椰子含354卡路里、榴莲更达459卡路里。

  其中椰子更含饱和脂肪,大量进食会令胆固醇水平过高,增加心脏病病发及中风风险。 在减肥的过程中你吃对水果了吗?
