你的大腦需要糖
- 能量減少，我們大腦解碼的能力也會下降[註1]
糖在腸胃如何作用
- 高糖高脂肪的食物會啟動我們的邊緣系統，讓我得到報酬，想要再吃
- 老鼠給naloxone, an opioid antagonist, 就變得不太想吃糖
- 有其他物質成癮的人，有比較高的比例想要吃糖
- 舌頭的甜味，腸胃裡的neuropod想要糖(a gut sensor cell)，和大腦裡的神經細胞也想要糖[3]
- 代糖只能取代舌頭的甜味
- 腸腦軸線
減少吃甜食的方法
- 多吃有營養且高品質的脂肪、蛋白質
- 加一些酸性食物(檸檬汁)
- 良好的睡眠可以減少對糖的渴求
注意不集中過動症會偏好甜食
不是甜食造成，但甜食會惡化狀況。
