谷氨酸钠(MSG) symptom complex refers to a group of symptoms some people experience after eating food containing MSG. These symptoms often include headache, skin flushing, and sweating.
虽然有些人将这些症状与MSG联系起来，但有最小的科学证据显示人类中两者之间的联系。据说，有无数的推荐支持这种理论，包括来自罗素Blaylock，神经外科和“兴奋毒素的作者”的警告：杀死的味道。“
美国食品和药物管理局（FDA）考虑了MSG安全。大多数人可以吃含有味精的食物，而不会经历任何问题。然而，小百分比的人对这种食品添加剂具有短期，不良反应。由于这种争议，许多餐馆宣传他们不会为他们的食物添加味精。
MSG是一种用于改善食物味道的食品添加剂。它已成为食品行业的重要添加剂，因为如果使用较低的质量或更少的新鲜成分，它不会损害风味。
MSG大多数是游离谷氨酸，或谷氨酸，在大多数食物中天然发现的氨基酸。它是通过发酵糖蜜，淀粉或甘蔗产生的。这种发酵过程就像是用于制作葡萄酒和酸奶的过程。
The FDA categorizes MSG as “generally recognized as safe” (GRAS). The FDA also categorizes salt and sugar as GRAS. However, there’s controversy over the lack of oversight the FDA has in the introduction and use of additives by the food industry.
According to theCenter for Science in the Public Interest (CSPI)，许多GRAS食品不会经历这种安全索赔所需的严格测试。例如，反式脂肪曾被识别为GRAS，直到足够的研究迫使FDA改变分类。
FDA要求公司添加味精ir foods to include the additive on the list of ingredients on the packaging. This is because some people identify themselves as sensitive to MSG. However, some ingredients naturally contain MSG, and food manufacturers may choose to use these ingredients to avoid disclosing the name MSG on the ingredient list.
If you intend to steer clear of MSG, exclude these main ingredients: autolyzed yeast, textured vegetable protein, yeast extract, glutamic acid, gelatin, soy protein isolate, and soy extracts.
人们在吃含有味精的食物后的两小时内可能会遇到症状。症状可以持续几小时到几天。常见的症状包括：
- headache
- sweating
- skin flushing
- numbness or burning in the mouth
- numbness or burning in the throat
- nausea
- 疲劳
Less commonly, people can experience severe, life-threatening symptoms like those experienced during allergic reactions. Severe symptoms may include:
Minor symptoms don’t require treatment. But you should go to an emergency room or call 911 right away if you experience severe symptoms.
People think MSG is linked to the symptoms previously listed. But this hasn’t been proven.
You may be sensitive to MSG if you become ill after eating foods that contain it. It’s also possible to be sensitive to foods that naturally contain high amounts of glutamate.
您的医生将评估您的症状和膳食摄入量，以确定您是否对MSG敏感。如果您正在经历严重的症状，例如胸痛或呼吸困难，您的医生可以检查您的心率，请执行心电图to analyze your heart rhythm, and check your airway to see if it’s blocked.
治疗可能会根据您症状的类型和严重程度而变化。
治疗常见症状
Mild symptoms usually don’t require treatment. Taking over-the-counter (OCT) pain relievers may ease your headache. Drinking several glasses of water may help flush the MSG out of your system and shorten the duration of your symptoms.
Treatment for severe symptoms
Your doctor may prescribe抗组胺药药物为了缓解呼吸困难，喉咙肿胀或快速心跳等严重症状。
研究表明，在正常金额中消耗MSG是安全的。但是，如果您在消耗味精后遇到不利症状，那么避免包含它的食物是个好主意。
当你在一家餐馆吃饭时，请问他们是否向他们的食物添加消息，如果他们没有识别菜单上的食物，因为无消息。此外，如果您认为您对含有大量谷氨酸谷氨酸盐的食物敏感，请与您的医生或营养师讨论吃特殊饮食，以消除含有很多的食物。
If your symptoms were minor, you don’t necessarily have to stop eating the foods you enjoy. You may be able to reduce your symptoms by eating only small amounts of foods that contain MSG.
