We’re back with MSG, the additive most beloved yet at the same time despised by many!
MSG consumption has been linked with diseases like obesity, Chinese Restaurant Syndrome a.k.a. MSG-complex Syndrome, neurotoxicity and reproductive abnormalities….
BUT~~~!
Most of these studies used rodents as subjects, and a VERY HIGH dosage of MSG was given than normal human intake levels. Rodent studies can determine safety levels for food additives, but it cannot represent toxicity in humans at the levels consumed in food.
Also, MSG was given directly into the animals’ stomach to observe for harmful health effects. This is not the typical route for food in a human body, remember food has to be digested and metabolised when passing through our digestive tract.
So...do you mean MSG is healthy?
Well, we’re not exactly saying that.
You see, some people do have MSG sensitivity which causes them to experience headaches, numbness and nausea. Some would even experience eczema where they get red and itchy skin rashes. This is real torture for them. Hence this is why MSG needs to be labelled in food products.
Stay tuned to find out how to identify hidden ingredients which contain MSG in part 3!
今天的主角光環再次回到大家又愛又恨的食品添加劑—“味精”身上！
味精食用被視為與各種疾病及健康問題相關，其中包括肥胖症，味精症候群又稱“中餐館症候群”，神經毒性，生殖異常等等。
可是，事實是？
這方面大部分研究以囓齒動物為實驗對象，而且還使用了非常高，甚至超過正常人攝入量的劑量。另外，囓齒動物研究有助於確定食品添加劑的安全食用量，但並不能代表會在人體內造成同等毒性。
此外，為了觀察味精是否對健康有害，它通常被直接注入動物們的胃。然而，這不是食物在人體內正常的途徑，因為食物在經過我們的消化道時是會被消化和代謝掉的啊！
那麼，味精是健康的咯？
也不完全是這個意思。
有些人對味精過敏，會出現頭痛，發麻，噁心等症狀，有的人甚至會得濕疹，身上又紅又癢，痛苦不堪。這就是給食品標記味精的原因。
下一期會教大家如何識別包含味精的隱藏成分，千萬別錯過了哦！
