甜菊糖会影响血糖吗？
摘要
本视频直接回答了一个常见疑虑：stevia（甜菊糖）是否会升高blood sugar（血糖）水平。Berg 博士的结论是，甜菊糖不会升高血糖或insulin（胰岛素），可以安全用作代糖——但有一个关于添加成分的重要注意事项。
核心要点
- 甜菊糖不会升高血糖水平 —— 甜菊糖的甜味不会欺骗身体，使其产生摄入真正糖分的反应
- 甜菊糖不会触发insulin（胰岛素）反应，因此对于需要管理blood sugar regulation（血糖调节）的人群来说是安全的
- 甜菊糖会引发hypoglycemia（低血糖）→ 肾上腺素 → Cortisol 皮质醇（皮质醇）分泌连锁反应的担忧并无依据
- 纯甜菊糖作为代糖食用是安全的
- 注意含有麦芽糊精或添加糖的甜菊糖产品，这些添加剂可能带来问题
- 部分甜菊糖产品含有赤藓糖醇（erythritol），可能为转基因来源（通常源自玉米）——如有顾虑，请选择非转基因版本
- 两种食物味道相似，并不意味着身体对它们的代谢方式相同
详细内容
”甜味 = 糖分反应”的误区
一种常见的误解认为，由于甜菊糖尝起来很甜，身体无法将其与真正的糖区分开来。这一理论所描述的连锁反应如下：
- 甜菊糖的甜味被感知
- 身体反应如同摄入了糖分 → blood sugar（血糖）升高
- 释放insulin（胰岛素）以降低血糖
- 出现hypoglycemia（低血糖）
- Adrenal glands（肾上腺）释放肾上腺素和Cortisol 皮质醇（皮质醇）以进行补偿
- 肾上腺系统承受慢性压力
Berg 博士明确表示，这种情况并不会发生。身体不会仅仅因为两者都尝起来甜就以相同方式对待甜菊糖和糖。味道相似并不等于代谢效应相同。
甜菊糖的实际作用
- 甜菊糖不会升高血糖
- 甜菊糖不会刺激胰岛素分泌
- 可作为代糖自由使用，而不会产生真正糖分所带来的代谢后果
购买甜菊糖产品时的注意事项
并非所有甜菊糖产品都一样。需要注意以下两种常见添加剂：
- 麦芽糊精或添加糖：部分市售甜菊糖混合产品含有这些填充物，确实会升高血糖。请务必查看成分标签。
- 赤藓糖醇（Erythritol）：部分产品将甜菊糖与赤藓糖醇结合用作膨松剂。赤藓糖醇通常由玉米提取，可能为转基因来源。选择经非转基因认证的产品可避免此问题。
建议： 使用不含任何额外成分的纯甜菊糖，以获得最干净的效果。

Does Stevia Affect Your Blood Sugar?
Summary
This video directly addresses a common concern about whether stevia can raise blood sugar levels. Dr. Berg concludes that stevia does not increase blood sugar or insulin, and is safe to use as a sugar substitute — with one important caveat about added ingredients.
Key Takeaways
- Stevia does not raise blood sugar levels — the sweetness of stevia does not trick the body into responding as if it were real sugar
- Stevia does not trigger an insulin response, making it safe for those managing blood sugar regulation
- The concern that stevia causes a chain reaction of hypoglycemia → adrenaline → Cortisol 皮质醇 release is unfounded
- Plain stevia is safe to consume as a sugar substitute
- Watch out for stevia products that contain maltodextrin or added sugar, as these additives can be problematic
- Some stevia products contain erythritol, which may be GMO (often corn-derived) — opt for non-GMO versions if this is a concern
- Just because two things taste similar does not mean the body processes them the same way
Details
The “Sweet = Sugar Response” Myth
A common misconception holds that because stevia tastes sweet, the body cannot distinguish it from real sugar. The proposed chain of events in this theory goes:
- Stevia sweetness is detected
- Body responds as if sugar was consumed → blood sugar rises
- Insulin is released to bring blood sugar down
- Hypoglycemia results
- Adrenal glands release adrenaline and Cortisol 皮质醇 to compensate
- Chronic stress is placed on the adrenal system
Dr. Berg explicitly states this does not happen. The body does not treat stevia the same as sugar simply because both taste sweet. Similarity in taste does not equal similarity in metabolic effect.
What Stevia Actually Does
- Stevia does not raise blood sugar
- Stevia does not stimulate insulin secretion
- It can be used freely as a sugar substitute without the metabolic consequences associated with real sugar
What to Watch Out For in Stevia Products
Not all stevia products are created equal. Two common additives to be aware of:
- Maltodextrin or added sugar: Some commercially prepared stevia blends include these fillers, which can raise blood sugar. Always check the ingredient label.
- Erythritol: Some products combine stevia with erythritol as a bulking agent. Erythritol is often derived from corn and may be GMO. Choosing a non-GMO certified product avoids this issue.
Recommendation: Use plain stevia with no additional ingredients for the cleanest result.
