🦠 高纖＝養腸道菌＝護大腦
📚 研究重點整理
1️⃣ 高纖飲食 → 強化腸道菌生態
*🧫 腸道菌分解纖維 → 產生短鏈脂肪酸（SCFAs）
*🛡 丁酸（Butyrate）維持腸道屏障、降低發炎
*🔄 強化「腸–腦軸」雙向溝通
*🧠 與較低失智風險、較佳認知功能有關
2️⃣ 纖維攝取高 → 失智風險較低
*📉 高纖族群死亡風險下降 15–30%
*📊 2022年研究：高纖攝取者失智風險較低
*🦠 補充益生元3個月 → 雙歧桿菌增加、認知表現提升
3️⃣ 低纖＝菌相失衡＝慢性發炎
*⚠️ 阿茲海默症患者腸道中
➜ 產丁酸菌較少
➜ 發炎指數較高
*🧬 丁酸不足，腦部保護力下降
🌱 怎麼養好腸道菌？
*🌾 全穀物
*🫘 豆類
*🍎 水果
*🥜 堅果種子
*🥦 多樣植物性飲食
📌 建議每日約 25–30克膳食纖維
📣 Tcell-1 原生益菌特點
* 來自人體腸道的原生菌株
* 有助於調整腸道菌叢平衡
* 協助建立穩定腸道微生態
* 與益生元搭配，可形成「菌＋菌糧」支持環境

🦠 High Fiber = Nourished Gut Microbiota = Brain Protection
📚 Key Research Findings
1️⃣ A High-Fiber Diet → Strengthens the Gut Microbiota Ecosystem
*🧫 Gut microbiota break down fiber, producing short-chain fatty acids (SCFAs)
*🛡 Butyrate helps maintain the intestinal barrier and reduce inflammation
*🔄 Strengthens communication along the gut–brain axis
*🧠 Associated with a lower risk of dementia and better cognitive function
2️⃣ High Fiber Intake → Lower Risk of Dementia
*📉 Mortality risk reduced by 15–30% in high-fiber groups
*📊 A 2022 study showed that high fiber intake is associated with a lower risk of dementia
*🦠 Three months of prebiotic supplementation → increased Bifidobacterium levels and improved cognitive performance
3️⃣ Low Fiber Intake = Microbial Imbalance = Chronic Inflammation
*⚠️ In Alzheimer’s patients:
➜ Fewer butyrate-producing bacteria
➜ Higher inflammation indices
*🧬 Butyrate deficiency leads to reduced brain protection
🌱 How to Maintain a Healthy Gut Microbiota
*🌾 Whole grains
*🫘 Legumes
*🍎 Fruits
*🥜 Nuts and seeds
*🥦 A diverse, plant-based diet
📌 Recommended daily intake: approximately 25–30 grams of dietary fiber
📣 Tcell-1 Native Probiotics — Key Features
* Native strains derived from the human gut
* Help regulate gut microbiota balance
* Support the establishment of a stable gut microbiota
* When paired with prebiotics, they help create a supportive “bacteria + prebiotic diet” environment
高纖飲食能改善健康、延長壽命，甚至保護大腦。然而，許多人仍未達到這項「關鍵營養素」的建議攝取量。
