科普專欄–薯不揀單 - 深入淺出–生酮飲食對人體的其中一種影響

高脂低碳餐單，亦即是生酮飲食，越漸普及化，經常標榜為減肥的有效秘方。594Please respect copyright.ＰＥＮＡＮＡBO9JpyT6NJ

的而且確，生酮飲食可以促進脂肪燃燒，而且會大量消耗身體的糖原，而每一個單位的糖原會黏上四個單位的水份關係，生酮飲食短期間會消耗身體水份含量，得以獲取快速的減磅效果。594Please respect copyright.ＰＥＮＡＮＡvjUrYjfNee

但另一方面，生酮飲食包含眾多高脂食物，而這些食物一直被指責為心臟病、癡肥糖尿病等的元兇，那麼究竟生酮飲食是好還是壞呢？594Please respect copyright.ＰＥＮＡＮＡoWwjOdgRlT

（圖2）有科學家進行了人體測試(Ref1)，找來14名年齡為27-42歲男性單車運動員，分成兩組進行持續六個月以上的生酮飲食(LCHF)及均衡飲食(Mixed)的飲食管理，成份如圖中所示。594Please respect copyright.ＰＥＮＡＮＡlTzbxQHeJE

（圖3）六個月的餐單後，兩組人各自進食含75克葡萄糖的食物，然後再分別量度血糖及血液胰島素的濃度。594Please respect copyright.ＰＥＮＡＮＡfVb7X3mE08
594Please respect copyright.ＰＥＮＡＮＡhTTc7j2dCc
594Please respect copyright.ＰＥＮＡＮＡthiugMGid1
如左圖所示，生酮飲食(LCHF)組別的血糖明顯比均衡飲食(Mixed)為高。594Please respect copyright.ＰＥＮＡＮＡ2f56jkS9wK
594Please respect copyright.ＰＥＮＡＮＡ3NXtKdPlA0
而且亦可見生酮飲食(LCHF)組別胰島素的產生時間較均衡飲食(Mixed)為延遲。594Please respect copyright.ＰＥＮＡＮＡUVT2aA8Tcn
594Please respect copyright.ＰＥＮＡＮＡl2XhSuJWrC
這歸咎於生酮飲食(LCHF)組別的肌肉擁有較少GLUT4及IRS1蛋白質；594Please respect copyright.ＰＥＮＡＮＡsY5a9wFw61
GLUT4及IRS1分別為其中一種負責吸取葡萄糖及接收胰島素的蛋白質。594Please respect copyright.ＰＥＮＡＮＡIlcX8ecEsb
594Please respect copyright.ＰＥＮＡＮＡu3D9MG9fl5
（圖4）雖然兩組人員在血糖及胰島素相關方面有顯著分別，但各種與新陳代謝有關的蛋白酶以及肌肉組成的比例，並沒有因為飲食不同而有所轉變。594Please respect copyright.ＰＥＮＡＮＡ8VToWuPsXs
594Please respect copyright.ＰＥＮＡＮＡ1mH7K7ccpK
594Please respect copyright.ＰＥＮＡＮＡoZcE3uwHLu
當然，與新陳代謝有關的蛋白酶數量繁多，不能擔保表外的蛋白酶會否有所影響。594Please respect copyright.ＰＥＮＡＮＡqN3S14Sjqv
594Please respect copyright.ＰＥＮＡＮＡPiVEXRUxNp
生酮飲食測試者需要更長的時間才能降低血糖，相信是因為長期攝取低碳水化合物而引起的轉變，會否因此增加糖尿病的機會還成未知之數；594Please respect copyright.ＰＥＮＡＮＡHtvwp9a8W2
不過生酮飲食本身就是低糖飲食，血糖理論上不會超標，所以根本沒有相干。594Please respect copyright.ＰＥＮＡＮＡSEaf3a0AjE
594Please respect copyright.ＰＥＮＡＮＡ8eQs6cda89
之於生酮飲食究竟會否引起心臟病等問題，還有待更詳細的長期人體實驗才能證實得到。594Please respect copyright.ＰＥＮＡＮＡyNSCeDz1UJ
