科普專欄–薯不揀單 - 深入淺出–天然基因變異造就出對人體更為健康的豌豆

進食高碳水化合物含量的食物，血糖難免會有所增加。長期血糖過高水平的話，將會增加患上二型糖尿病的風險。976Please respect copyright.ＰＥＮＡＮＡHfA4iVN4UT

而血糖飄升的幅度，好取決於食物的物理結構、內含的碳水化合物種類、以及進食後所引起的神經及荷爾蒙反應。976Please respect copyright.ＰＥＮＡＮＡkzdowkjezA

（圖2）食物的結構，很大程度由相應的蛋白酶主宰。隨著大自然間基因的變異，對應的蛋白酶功效亦會有所不同。976Please respect copyright.ＰＥＮＡＮＡtw4vjO38jJ

一道負責控制澱粉結構的基因在天然變異下，造就出了rr豌豆品種，並促使其澱粉結構較原本的RR品種相對較長。976Please respect copyright.ＰＥＮＡＮＡpJzRmR9nm5

（圖3）有科學家將這兩種豌豆進行人體測試（Ref1)，並得出有趣的結果。976Please respect copyright.ＰＥＮＡＮＡXAgCGZ2A2Q

12名健康人士分別進食50克RR及rr豌豆後，食用同佳rr豌豆人士的血糖及胰島素水平明顯比RR豌豆為低。976Please respect copyright.ＰＥＮＡＮＡuTfyWDFCiv

（圖4）利用機器往豌豆施壓後，RR豌豆呈糊狀形態，而rr豌豆則~~拒絕自首~~分成兩塊。976Please respect copyright.ＰＥＮＡＮＡ4bbNHGZUmo

對比RR豌豆，rr豌豆最終化成為Butyrate的百分比較之為高。976Please respect copyright.ＰＥＮＡＮＡLHUNMFsAlV
976Please respect copyright.ＰＥＮＡＮＡidIgN6Xji5
Butyrate是腸道細菌消化碳水化合物的產物，亦即是說rr豌豆相對上地並沒有效被腸道吸收，而是成為了腸道細菌的食物，間接降低了碳水化合物進入血液循環系統的機會。976Please respect copyright.ＰＥＮＡＮＡ9QKgqOXIU0

依照這邏輯的話，若然我們在其他殼物中以依樣胡蘆的方法修改那基因，大有可能會得到進食後血糖提升速度相對上較慢的殼物，長遠能減低糖尿病增長的風險。976Please respect copyright.ＰＥＮＡＮＡysXNjoVk6W
