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。882Please respect copyright.ＰＥＮＡＮＡy95W6R56Kq

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。882Please respect copyright.ＰＥＮＡＮＡCCTudTMU7b

但除此之外，攝取食用纖維還有甚麼好處呢?882Please respect copyright.ＰＥＮＡＮＡlH5hm1UmvK

（圖2）講述之前，我們要提及一下關於膽汁的背景資料。882Please respect copyright.ＰＥＮＡＮＡLX9XIjxD4t

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。882Please respect copyright.ＰＥＮＡＮＡ3fdNHTapX2
882Please respect copyright.ＰＥＮＡＮＡZvVfvMPtB8
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。882Please respect copyright.ＰＥＮＡＮＡDZpYEjjdQc
882Please respect copyright.ＰＥＮＡＮＡM9dnZEgAfS
（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)。882Please respect copyright.ＰＥＮＡＮＡWcUjJmweOF

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。882Please respect copyright.ＰＥＮＡＮＡ55eHCeFbsB

(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。882Please respect copyright.ＰＥＮＡＮＡ1HUom5GBRV

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)。882Please respect copyright.ＰＥＮＡＮＡwC2CsrhRIP
882Please respect copyright.ＰＥＮＡＮＡY41E1u6joK
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。882Please respect copyright.ＰＥＮＡＮＡfb8ewYvlaq
