味精(MSG)是否安全?/ Is MSG safe?


(原创于:www.eliaus.com   博主微信:us20120514)

味精是我们都非常熟悉的普通食品添加剂。 有些人说味精对身体有害,也有人说它是绝对安全和无害的,即使美国FDA(食品和药物管理局)把它视为GRAS(一般被认为是安全的)。 那么味精真的很安全吗?

Is MSG safe?

A common food additive that we all know too well is MSG.  Some people say it is bad for you while others say that it is completely safe and harmless even the FDA (Food and Drug Administration) of the United States considers it as GRAS (Generally Recognized As Safe).  So is MSG really safe? 


• 酵母抽提物
• 谷氨酸(麸氨酸)


• 酱油
• 原汁
• 肉汤
• 玉米淀粉
• 玉米油



• 体温

Well, let’s start with the different names that MSG appears as on food labels.

  • Msg (Monosodium glutamate)
  • Autolyzed yeast
  • Hydrolyzed protein
  • Hydrolyzed vegetable protein
  • Sodium caseinate
  • Yeast nutrient
  • Yeast extract
  • Textured Protein
  • Torulo yeast
  • Glutamate
  • Glutamic acid

Even though it is not labeled, MSG can usually be found in 

  • Flavors/Flavorings
  • Seasonings
  • Natural Flavors/Natural Flavorings
  • Natural Pork Flavoring
  • Natural Beef Flavoring
  • Natural Chicken Flavoring
  • Soy Sauce
  • Soy Protein Isolate
  • Soy Protein
  • Bouillon
  • Stock
  • Broth
  • Malt Extract
  • Malt Flavoring
  • Barley Malt
  • Anything Enzyme Modified
  • Carrageenan
  • Maltodextrin
  • Pectin
  • Corn Starch
  • Corn Oil
  • Anything Ultra-Pasteurized

In a study conducted in North and South china, people where compared on how much MSG they had in their diet. The study concluded that the more people ate MSG the more likely they would be overweight. In animal studies, MSG can create lesions (a damaged spot) in the hypothalamus within the brain as well as cause leptin resistance.

The hypothalamus is important in controlling 

  • Body Temperature
  • Thirst
  • Appetite and weight control
  • Emotions
  • Sleep cycles (trouble sleeping)
  • Sex drive (difficulty with sexual reproduction)
  • Breast milk (releasing breast milk, starting and starting production of breast milk)
  • Blood pressure and heart rate
  • Production of digestive juices
  • Balancing bodily fluids
  • Thyroid (regulates metabolism, energy levels, developmental growth children and adults)





Leptin is a hormone produced in fat cells.  When leptin levels are high they tell the brain to eat less and to burn more energy.  When leptin levels are low they tell the brain to eat more (the thinks the body is starving) and to conserve energy.  So, when someone is leptin resistant, the brain does not respond to leptin properly thinking that the body has low leptin levels.  This in turns makes the brain think that the person is starting thus making them eat more and gain weight.  Leptin communicates with the hypothalamus of the brain.  Now, if MSG damages this part of the brain then what do you think happens?  The brain may think it is starving and will not respond to leptin properly.

Some symptoms of MSG consumption especially if intolerant include

  • Burning sensation in the back of the neck, forearms and chest
  • Numbness in the back of the neck, radiating to the arms and back
  • Tingling, warmth and weakness in the face, temples, upper back, neck and arms
  • Chest pain
  • Headache
  • Nausea
  • Rapid heartbeat
  • Bronchospasm (difficulty breathing) in MSG-intolerant people with asthma
  • Drowsiness
  • Weakness

味精通过令脑细胞兴奋死亡而导致其损伤。 在一定程度上(不完全),镁,适当形式的维生素C和维生素E可以保护大脑免受如:神经毒素味精造成的危险。 此外,未经已经显示穿过胎盘并影响子宫中发育中的胎儿的大脑。味精多年来对脑部的进一步损伤也可能是发展肌萎缩性侧索硬化症,帕金森病和阿尔茨海默病的人群中的一种致病因子。

那么为什么会添加到食物? 如你所知,味精增加了食物的味道和香气。 这对于公司来说非常棒,因为它们使食物更加美味可口,让人们不断回来。 这对于公司和餐馆来说有助于出售自己的产品和增加业务是个好消息。
如您所见,味精会导致许多健康问题,并损害大脑。 那么为什么我们没有看到它被禁止?

MSG causes its damage by exciting brain cells to death.  To an extent (not completely), magnesium, the proper forms of vitamin C and vitamin E can protect the brain from dangerous neurotoxins such as MSG.  Additionally, MSG has been shown to cross the placenta and affect the brain of the developing child in the womb.  The progressive damage to the brain by MSG over many years can also be one of the causative agents in people who develop Amyotrophic Lateral Sclerosis, Parkinson’s, and Alzheimer’s.

So, why is it added to food?  As you know, MSG increases the flavor and aroma of food.  This is great for companies as it makes their food more desirable and tasty, so that people keep coming back for more.  This is great news for companies and restaurants to help sell their products and increase business.   

As you can see, MSG causes many health problems and damages the brain.  So, why have we not seen it banned?


原因在于,谷氨酸工业(那些对味精有经济利益以提高利润的人)在1977年创建了名为国际谷氨酸技术委员会(IGTC)和谷氨酸协会(TGA)的非营利组织。IGTC是研究味精的行业组织。 IGTC以研究资助的形式花钱,使科学家和机构进行促进味精作为人类消费安全的研究。 虽然国际食品信息委员会(IFIC),往往资助不同的卫生机构,主要由食品工业与TGA一起资助,但向公众宣传,味精对人类来说是安全的,

正如你所看到的,在我们生活的世界里,味精不会很快消失。 因此,由你掌握自己的手,保护家人和亲人的健康,

The reason lies in that the glutamate industry (those who have a financial interest in MSG to boost their profit) created the nonprofit organization called International Glutamate Technical Committee (IGTC) and The Glutamate Association (TGA) back in 1977.  The IGTC is the research organization for the MSG industry.  The IGTC spends money in the form of research grants getting scientists and institutions to conduct studies which promote MSG as being safe for human consumption.  While The International Food Information Council (IFIC) which is primarily funded by the food industry along with TGA promote to the public that MSG is safe for humans often funding different health organizations.

As you can see, in the world we live in, MSG won’t disappear any time soon.  Therefore, it is up to you to take matters into your own hands and protect the health of your family and loved ones.

So, are you still eating that tasty MSG?
