EP57. 專題系列4: 糖 vs 代糖

科學十分鐘

這次的專題系列來跟大家講講糖跟代糖的差別，喝零卡可樂為什麼喝完好像嘴巴會怪怪的？代糖跟糖又該怎麼選擇？或是代糖是怎麼做到零熱量的呢？這些解答都在這次的科學十分鐘專題系列！
內容延伸代謝途徑 （簡化很多大概讓大家知道一下）：
Carbohydrate metabolism:

• In the liver -> 20% glucose hit the liver cell -> Insulin -> IRS-1 -> SREBP1 -> Glucokinase takes glucose -> G6P -> Glycogen G6P -> Pyruvate -> TCA cycle -> ATP Co2 -> citrate ->De novo lipogenesis (making fat process) -> FAT -> VLDL -> heart disease

Sugar (glucose and fructose) metabolism:

• 100% hit the liver cell -> pyruvate -> TCA cycle mitochondria -> citrate -> VLDL -> free fatty acid -> insulin resistance -> non-alcholic fatty acid liver -> JNK -> inflammation -> IRS-1 insulin
