✨ 你听过 Beta-glucan（β-葡聚糖）吗？
很多人说它是「增强免疫 + 降胆固醇」的神奇物质。
可是 —— 事实并不这么简单。
💡 Beta-glucan 不只一种！
不同来源 = 不同结构 = 身体反应完全不同。
✔ 燕麦 / 大麦：β-1,3/1,4 —— 主要当膳食纤维用
👉 帮助降胆固醇、稳血糖、养肠道
✔ 蘑菇 / 酵母：β-1,3/1,6 —— 会直接刺激免疫细胞
👉 免疫力提升效果更强，但也更可能「太强」
⚠️ 不是每个人都适合！
如果你有自身免疫疾病（如红斑狼疮、类风湿、甲亢等）、器官移植史，或正在服用免疫抑制药物——
👉 免疫刺激型（蘑菇/酵母）β-glucan就要特别小心。
🥣 食物级（例如燕麦）一般较安全，但补充剂，还是建议就不能乱吃。目前研究不足。
营养师叮咛：
用对类型才有好处，用错反而会增加身体负担。
补充前先了解自己的情况，再决定适不适合。

✨ Have you heard of Beta-glucan (β-glucan)?
Many people call it a “magic booster” for immunity + cholesterol lowering.
But — it’s not that simple.
💡 Not all beta-glucans are the same!
Different sources = different structures = different effects.
✔ Oats / Barley (β-1,3/1,4):
👉 Works mainly like soluble fiber
👉 Helps lower cholesterol, stabilize blood sugar, and support gut health
✔ Mushrooms / Yeast (β-1,3/1,6):
👉 Directly stimulates immune cells
👉 Stronger immune response, but also higher risk for certain people
⚠️ Not suitable for everyone!
If you have an autoimmune condition (e.g., lupus, rheumatoid arthritis, hyperthyroidism), have had an organ transplant, or are on immunosuppressants —
👉 Be extra careful with immune-stimulating β-glucan supplements (mushroom/yeast types).
🥣 Food-based beta-glucan (like oats) is generally safer — but supplements are a different story.
Dietitian’s Note:
Using the right type helps you.
Using the wrong type may stress your immune system instead.
