卵磷脂 Lecithin × 肝臟健康
The evidence does not support a graded benefit for consumer soy lecithin on any clinical liver outcome.
The evidence does not support a graded benefit for consumer soy lecithin on any clinical liver outcome. Examine has no liver block for soy lecithin at all (coverage gap), and no randomized controlled trial evaluates generic soy lecithin for a clinical hepatic endpoint. The trial evidence that exists concerns a different, pharmaceutical-grade substance: the large, rigorous VA Cooperative Study 391 (n=789, 24 months, biopsy endpoint) of polyenylphosphatidylcholine was essentially null for alcoholic liver fibrosis progression (22.8% vs 20.0%, NS). The one positive NAFLD network meta-analysis (PMID 33269259) used short-duration studies with biochemical/ultrasound surrogate endpoints, had a Sanofi-employee author (Essentiale conflict of interest), and was self-rated low quality. AASLD/AGA do not mention lecithin, and Mayo, Cleveland Clinic and Harvard have no lecithin liver-health position. Because the consumer product has zero clinical-endpoint RCTs and the best pharmaceutical trial is null, an honest grade is U (insufficient evidence) rather than a substantive A-D.
評分透明度
所有分數由 7 層證據引擎計算，過程公開可查▸查看完整決策路徑（audit trail）
- compute_raw_score — 加權公式: L2×0.30 + L3×0.25 + L5×0.25 + L11×0.10 + L1×0.10 = 0.443
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (1 篇 > 0 negative)
- tier_strict_requirement_check — Tier 條件達標，未降階
- detect_disputes — 偵測到 0 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
台灣社群討論卵磷脂幾乎集中在哺乳塞奶與孕哺保健，少見以護肝/脂肪肝為目的的真實鄉民實測；肝臟健康框架多出自業配/affiliate 商業內容而非社群經驗。
無共識（社群幾乎無以護肝/脂肪肝為目的之卵磷脂實測心得；PTT/Dcard 脂肪肝串多談飲食、斷食、運動與好油，極少提及卵磷脂）
