β-葡聚醣 Beta-Glucan × 膽固醇
The evidence base for cereal (oat/barley) beta-glucan lowering LDL cholesterol is exceptionally consistent: four high-quality meta-analyses spanning 58+ RCTs and over 6,000 participants converge on an LDL reduction of roughly 0.
The evidence base for cereal (oat/barley) beta-glucan lowering LDL cholesterol is exceptionally consistent: four high-quality meta-analyses spanning 58+ RCTs and over 6,000 participants converge on an LDL reduction of roughly 0.19-0.27 mmol/L (about 5-10%) at a daily dose near 3 g, with similarly consistent total-cholesterol reductions. This consistency is reinforced by an unusually strong layer of regulatory and professional backing: an FDA Significant Scientific Agreement authorized health claim (21 CFR 101.81), EFSA Article 13(1) and Article 14 authorized claims, and explicit supportive positions from the AHA and NLA. However, every graded outcome is a surrogate lipid biomarker, not a hard cardiovascular endpoint (MI, stroke, cardiovascular mortality), and the absolute effect is modest and adjunct-sized rather than therapeutic. Because the totality is best characterized as strong, consistent, regulator-endorsed surrogate-marker evidence with a genuinely modest effect and no hard-endpoint confirmation, an independent grade of B is most defensible; an A would over-state certainty by treating surrogate-only evidence as if it were outcome evidence. The grade applies specifically to CEREAL (oat/barley) beta-glucan and must not be transferred to yeast/fungal beta-glucan, whose cholesterol evidence is not graded here.
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 = 0.7
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (3 篇 > 0 negative)
- tier_strict_requirement_check — | A→B 因 scope.conflation_risk=true 且 L11 獨評較低 (B7-2 tier cap)
- 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（PTT WomenTalk/FITNESS/MuscleBeach 為主）幾乎都把「β-葡聚醣降膽固醇」綁在『燕麥』食物上討論，而非獨立保健品。鄉民普遍認同燕麥代飯/取代精緻澱粉有助降膽固醇，常與紅麴比較，但常把效果與整體膳食纖維、飲食控制+運動混為一談。獨立的 β-聚葡萄糖膠囊（台酒健字號、酵母 Wellmune 等）在台灣多以『免疫調節』訴求行銷，極少有針對膽固醇的鄉民實測，相關頁面幾乎都是廠商/健康媒體 SEO 業配內容。
多數正面（但侷限於『燕麥』食物形式）：鄉民普遍認為燕麥代飯有助降膽固醇、優於地瓜，常與紅麴並列；惟效果多被歸因於整體膳食纖維與飲食控制，而非單一 β-葡聚醣。獨立 β-葡聚醣膠囊用於膽固醇則無共識、缺乏鄉民實測。
- 脹氣（高纖/燕麥吃多）
- 血糖上升（無糖燕麥片仍會明顯升血糖）
- 少數提到『可能造成身體發炎』之說法（未獲社群普遍認同）
依論壇被提及頻率，非銷售或品質排序。
- 桂格（燕麥/燕麥飲，超商可得）
- 廣吉 Quaker
- 台糖（燕麥片）
- 台酒 TTL β-聚葡萄糖膠囊（健字號免疫調節，非降膽固醇訴求）
