各款蔬果殼物均含有不同份量及款式的食用纖維,25-30克的食用纖維為每日建議的攝取量。819Please respect copyright.PENANA2XXcgReTnr

部份的食用纖維無法被腸道吸收,因而有助刺激腸道增加蠕動,防止便祕。同時它們亦有助增加飽肚感,減少進食量。819Please respect copyright.PENANAdbKHuFzUE3

但除此之外,攝取食用纖維還有甚麼好處呢?819Please respect copyright.PENANAQ3Zl3pHpQG

(圖2)講述之前,我們要提及一下關於膽汁的背景資料。819Please respect copyright.PENANA7zlYrqaunW

我們的肝臟會產生初級膽汁酸,作用是輔助脂肪在腸道裡更易被消化。819Please respect copyright.PENANAXRjY86crGC
819Please respect copyright.PENANAK4vizRhfBk
而當初級膽汁酸抵達腸道後,聚居在腸道的細菌會將初級膽汁酸改變成為次級膽汁酸。819Please respect copyright.PENANAewJiHgxh1q
819Please respect copyright.PENANAuvjE6RqUXX
(圖3)然而,某部份的次級膽汁酸對人體有害,被證實會促進腸道癌的誕生(Ref1)。819Please respect copyright.PENANA47lm2mQ4pA
819Please respect copyright.PENANAv3dfYOxDeJ
819Please respect copyright.PENANA61UTvdOvzu
而食用纖維則能夠與有害的次級膽汁酸結合,將它們帶走體外,防止它們長期聚居在腸道位置。819Please respect copyright.PENANAsiVeFmTYJ4

819Please respect copyright.PENANAimKLdVqg69
(圖4)另外,有部份腸道細菌依靠消化食用纖維維生。而長期沒有進食纖維的話,會導致腸道細菌品種失衡。819Please respect copyright.PENANALTiZ97taCD

819Please respect copyright.PENANApHwoS80fo6
久而久之,進食腸道黏液的細菌品種會助大起來,它們會導致腸道壁膜更為薄弱,使腸道更容易受到感染(Ref1)。819Please respect copyright.PENANAeuwrND0pQO
819Please respect copyright.PENANAfXg382dV6j
換句話說,攝取食用纖維能有助防止便祕、增加胞肚感以及減低腸道癌症及炎症發生的機會,絕對是不可或缺的營養。819Please respect copyright.PENANAMQ0DTa1dMh
