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。675Please respect copyright.ＰＥＮＡＮＡ3oD7CBUlhK

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。675Please respect copyright.ＰＥＮＡＮＡp0f7MkytXs

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？675Please respect copyright.ＰＥＮＡＮＡetNHp0fSTi

（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。675Please respect copyright.ＰＥＮＡＮＡzHlz7d5hP7

（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。675Please respect copyright.ＰＥＮＡＮＡYy6BpWRFmc
675Please respect copyright.ＰＥＮＡＮＡBiOzFQ5aVf
675Please respect copyright.ＰＥＮＡＮＡ8zCzGqtbYY
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。675Please respect copyright.ＰＥＮＡＮＡPEAS7XJmBF
675Please respect copyright.ＰＥＮＡＮＡpgGfJcqYMs
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。675Please respect copyright.ＰＥＮＡＮＡ5ON1Mm2qK8
675Please respect copyright.ＰＥＮＡＮＡrh6R4Su8qG
這歸咎於生酮飲食(LCHF)組別的肌肉擁有較少GLUT4及IRS1蛋白質；675Please respect copyright.ＰＥＮＡＮＡsORS1MXgw1
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。675Please respect copyright.ＰＥＮＡＮＡ1QrFlAKyZu
675Please respect copyright.ＰＥＮＡＮＡVrAEhEAcLn
（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。675Please respect copyright.ＰＥＮＡＮＡsDzdmoxZyc
675Please respect copyright.ＰＥＮＡＮＡM57ZEYUgRk
675Please respect copyright.ＰＥＮＡＮＡu2U9raf6Rr
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。675Please respect copyright.ＰＥＮＡＮＡgs7uUrxNA3
675Please respect copyright.ＰＥＮＡＮＡkFxCyA0f5L
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；675Please respect copyright.ＰＥＮＡＮＡrMvcSRI8J2
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。675Please respect copyright.ＰＥＮＡＮＡxugj7mYV7E
675Please respect copyright.ＰＥＮＡＮＡFVkp4hG0bY
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。675Please respect copyright.ＰＥＮＡＮＡhf1eALZZJ9
