原文吃光光XD,版娘回答太專業了,
我只針對有大大推文說對酒精燃燒變脂肪做解釋,
酒精在人體燃燒會產生7大卡/克的熱量
這點版娘在上一篇回文有提到,
而肝臟有一種名字叫做alcohol dehydrogenase的酵素,
這種酵素會把酒精(乙醇)氧化生成乙醛,
接著會再進一步把乙醛氧化生成乙酸,
然後乙酸會轉變成Acetyl-CoA,
而在這些過程當中,過多的酒精代謝伴隨著過多的NADH的形成,
因此過多的NADH會造成TCA CYCLE、糖質新生、脂肪酸氧化等化學反應出現問題,
而Acetyl-CoA的堆積會傾向脂肪酸的形成,
進而造成肝臟的三酸甘油酯的增加,
接下來就很精彩了,脂肪開始堆積在肝臟,脂肪肝形成了,
而這個現象若再不改善,再來肝硬化就出現了,自此人生由彩色變黑白的了Orz
各位看倌,別以為到現在就結束了,
剛才提到糖質新生的失調,
會造成糖質新生中的受質──乳酸的堆積,
當乳酸堆積在血液中時,就會演變成酸中毒,
這時候只有去掛ER了Orz
看倌們都已經看到這裡了,就把接下來看完吧!
方才不是提到糖質新生受到影響嗎?
所以當糖質新生受到影響,再加上個人飲食上的營養不良,
將會造成低血糖症,
而低血糖又會對CNS(中樞神經系統=大腦)造成破壞,
所以酗酒是不好的唷!!!
但是酒也不完全是不好的啦!
像是葡萄酒裡面的Resveratrol的成份,
可以促進人體長壽基因Sirtuin的作用,
所以很多東西少量對人體是有所幫助的,
但是一但過量,對人體就是有害的,
最後再次強調,不要酗酒!!!!!
