Meet the gastrointestinal tract!
The gastrointestinal tract is the path food takes from mouth to anus. It consists of the mouth (chewing, enzyme-assisted breakdown), esophagus (food propulsion), stomach (churning, storage), small intestine (nutrient absorption, hydrolysis), large intestine (absorbing water, ions, vitamins), rectum (storing waste), and anus (expelling waste ...

吃錯纖維，只會愈吃愈便秘！ 很多人一便祕，就會覺得自己「吃不夠蔬菜」。但從營養學角度來看，真正的問題可能不是吃得不夠，而是吃錯了纖維種類。 🧬 纖維的分別？ 膳食纖維主要分成兩種，它們對腸道的影響可以完全不同。 1️⃣ 水溶性纖維（Soluble Fiber） - 能吸水並形成凝膠 - 讓糞便變軟、更滑、更易排出 - 有肋穩定血糖、改善腸道菌群 - 對腸道敏感或容易脹氣的人特別友善 常見來源：燕麥、香蕉、蘋果、奇異果、番薯、洋車前子 2️⃣ 非水溶性纖維（Insoluble Fiber） - 增加糞便體積，維持腸道規律性 - 提供咀嚼感，增加飽腹感 - 刺激腸道蠕動，但對蠕動慢的人效果有限，甚至可能加重便祕 常見來源：菜心、通菜、油麥菜、白菜、各類粗纖維菜梗類 🚨 為什麼會發生「愈吃菜愈便秘」？ 便祕有很多種，但常見的一種是： 腸道蠕動速度慢 飲水不足 進食過量非水溶性纖維。 當糞便越撐越大，同時沒有足夠水份讓糞便變軟 → 越吃越脹，越吃越難排出。 但是非水溶性纖維仍然是健康飲食的重要部分，只是若你腸道蠕動偏慢、容易脹氣、排便疼痛，短期內大量攝取可能不太適合。 🌱 改善便祕的小建
