from 雷比特生物空中講 · host 雷比特老師
深入探討維生素A及其前驅物胡蘿蔔素在人體健康中的關鍵作用。它解釋了維生素A如何作為視覺、上皮組織健康、生長及免疫功能不可或缺的「超級英雄」，並追溯其在科學史上的發現歷程。資料也詳細闡述植物性胡蘿蔔素在體內轉化為維生素A的「變身」機制，強調了適量攝取的重要性。此外闡明維生素A缺乏症（如夜盲症、乾眼症）和過量症（如肝臟損害）的潛在風險，同時提供透過均衡的「彩虹飲食」來聰明攝取維生素A的實用建議，而非僅依賴補充劑。 聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址 https://g.co/gemini/share/23a65e80854d Powered by Firstory Hosting
