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?

你有服用西药吗 如果有,你是否知道以下内容?/ Are you taking Western medicine? If you are, are you aware of the following?

你有服用西药吗? 如果有,你是否知道以下内容?

当有人听到一种新的药物时,挑剔的患者可能会问:“这种药物是否有副作用?”嗯,询问是否有副作用是值得称赞的,因为没有人希望吃完这个药后引起头痛或吃完那个药后又引起便秘 。 更不要说某些药物引起的一些更严重的副作用可能是具有相当破坏性的,比如造成血栓或心脏损伤等等。 还好的是不是每个人在服用药物后都会遭受副作用,或者意识到会有副作用。 然而,大多数人在服用西药时并不知道甚至短期使用都会产生负面影响。


这可能有多严重? 那我们来看看一些药物可以做什么。

Are you taking Western medicine?  If you are, are you aware of the following?

When someone hears about a new medication, the discerning patient may ask, “Does this medication have any side effects?”  Well, it is commendable to ask about side effects as no one may want to have a headache from this medication or constipation from this other one.  Let alone some of the more serious side effects of certain medications that can be quite devastating like blood clots or heart damage to name a few.  Good thing is not everyone will suffer a side effect when taking a medication or be aware of one.  Nevertheless, there is something that most people are not aware of when taking western medication and even short term use can have a negative impact. 

Medications can strip the body of vital vitamins, minerals, and other nutrients.

How serious can this be?  Well, let’s see what some medications can do.

我们从常用的抗生素,四环素开始吧。 四环素可以防止身体吸收:




Let’s start with the commonly use antibiotic, TetracyclineTetracycline can prevent the body from absorbing:

  • Iron (prevents anemia, magnesium (lowers the risk of type 2 diabetes)
  • Zinc (helps with concentration and memory, reduce severity of premenstrual syndrome)
  • Calcium (helps build and strengthen bones)(aids in normal function of the heart).

Antibiotics in general can:

  • Deplete the body of B vitamins
  • Vitamin K (important for heart health, bones, reduces menstrual pain and bleeding). Antibiotics
  • Kill off good bacteria (probiotics) in the digestive system (help with digestion and absorption of nutrients, improves the immune system, improves mood).

















Beta blockers a group of drugs to lower high blood pressure can:

  • Depletes an important enzyme called CoQ10 (ubiquinone).

CoQ10 is important to

  1. Strengthen the immune system
  2. Help with fatigue
  3. Prevent heart attacks
  4. Prevent heart failure.
  • Additionally, this group of drugs depletes melatonin which helps with
    1. Sleep
    2. Strengthens your immune system
    3. Slows down cellular aging
    4. Helps prevent cancer (especially breast).

Another group of drugs used to lower blood pressure known as ACE inhibitors deplete zinc

While another group of medications to lower blood pressure, Calcium Channel Blockers deplete potassium

Another group of drugs used to lower blood pressure Diuretics deplete the body of

  • B vitamins (important in preventing for certain kinds of anemia, helps with energy levels).

Additionally, Thiazide diuretics decrease 

  1. Magnesium
  2. Zinc

Loop diuretics deplete 

  1. Magnesium
  2. Calcium
  3. Potassium (prevents muscle spasms, lowers blood pressure)
  4. Zinc
  5. Vitamin C (improves immune system, helps collagen formation).

A commonly used medication for heart failure, Digoxin lowers levels of

  • Calcium
  • Magnesium
  • Phosphorus (strengthens bones, detoxifies body, helps improve energy levels)
  • Vitamin B1 (Thiamine)(improves appetite, increases energy levels, protects the nerves)
  • Potassium

Another major group of drugs that help lower cholesterol known as Statins also lower CoQ10 levels by preventing the production of the enzyme in the body.

Some medications deplete the body of nutrients by making it work faster. This includes gout medication (Colchicine), some steroids, and some antibiotics such as Penicillin (depletes potassium) and gentamicin (causes imbalances of magnesium, potassium, and calcium).

一些流行的,治疗胃灼热,胃酸反流和溃疡的药物可能会导致维生素B12缺乏症。 维生素B12对记忆,脑功能,预防某些类型的贫血和能量水平很重要。 它还降低叶酸水平(帮助婴儿的神经系统,面部和心脏正常发育,有助于能量水平,帮助某些种类的贫血),也降低。 此外,这些药物降低维生素D的吸收(预防心脏病,缺乏钙会造成骨质疏松症,免疫系统差,痴呆)。 这些药物的一个亚类,质子泵抑制剂,如奥美拉唑也会消耗的水平。

用于抑郁症的药物称为抗抑郁药,会使身体耗尽各种B族维生素,比如维生素B 12叶酸等。

Popular medications to treat heartburn, acid reflux, and ulcers can cause Vitamin B12 deficiency.  Vitamin B 12 is important for memory, brain function, prevent certain types of anemia, and energy levels.  It also decreases levels of folate (proper development of the baby’s nervous system, face, and heart, helps with energy levels, helps with certain kinds of anemia), iron, and zinc.  Additionally, these medications lower the absorption of calcium and Vitamin D (prevents heart disease, osteoporosis, poor immune system, dementia).  A subclass of these medications, proton pump inhibitors like omeprazole deplete levels of magnesium as well.

Medications used for depression, called antidepressants make the body use up various B vitamins such as Vitamin B 12 and folate.



•维生素B 12


•维生素B 12

Birth control and hormone replacement therapy medications deplete the body of

  • Vitamin B6 (reduces premenstrual syndrome, helps with anxiety and depression, helps with low energy levels),
  • Vitamin B 12
  • Folate
  • Magnesium.

The commonly prescribed medication for diabetes, Metformin reduces levels of

  • Vitamin B 12
  • Folate



• 维生素C





• 维生素C





The commonly used pain medication Hydrocodone depletes the body of

  • Vitamin C
  • Iron
  • Potassium
  • Folate

Pain medications such as Ibuprofen, Naproxen that also help reduce inflammation deplete

  • Folate

Aspirin which is used for pain or to prevent stroke and heart attack from a clot depletes

  • Vitamin C
  • Iron
  • Potassium
  • Zinc
  • Folate

Tylenol (acetaminophen) which is popularly used for pain and fever depletes

  • CoQ10
  • Glutathione (protects against cancers such as breast, helps detoxify the body, and protects the liver).

Lastly, medications used for constipation known as laxatives deplete 

  • Potassium
  • Calcium




Be aware that the list above does not cover all medications since not all medications have been studied to see if they deplete vitamins, minerals, and other nutrients.  Hopefully, this gives you a better perspective concerning Western medicine sometimes called conventional medicine.  As you can see, these medicines not only can cause side effects, but nutritional deficiencies and in turn the nutritional deficiencies can adverse effect your health.  So, the foundation to being healthy is having a balanced organic or gmo-free diet.  However, many people need supplementation with vitamins, minerals and nutrients, since their diets are poor, do not have the knowledge of a proper diet, do not have access to good quality food, or a combination of these factors. 

Supplementation with vitamins, minerals, and nutrients needs to be tailored to each person.  Each person needs certain vitamins and minerals which are dependent on a combination of factors such as current age, health status, emotional state, nutritional status, etc.  

A one size fits all approach can be detrimental. 

例如,有人在互联网上询问一个受欢迎的卖家,“你有什么产品对我的贫血好?”然后这个完全没有,或者只有有限的健康知识的卖家通过网上复制粘贴其他人的文章以获得他人的信誉,然后就告诉你, “我有这个非常棒的铁剂,能解决您的贫血问题。”。可卖方没有考虑到,或者甚至不知道有不同的营养不良的原因可以造成贫血,或患者可能正在流血,甚至危及生命,需要去看医生治疗的。又比如说,如果买方的铁缺乏不是造成该人贫血的原因,而且是由钴胺素或叶酸缺乏或其他营养缺乏引起的,而买方的铁水平实际上是正常的。现在会有什么事发生呢?这位听信的买家就会服用额外的铁。我们知道买家的贫血没有得到医治。在数周或数月的时间内,买方开始出现铁毒性症状,如呕吐,腹泻,嗜睡,身体毛发丧失,关节疾病,慢性感染,肝衰竭和内部出血。你想成为那位买家吗?我不会。



For example, someone asks a popular seller on the internet, “What is good for my anemia?”  So, the seller with limited to no health knowledge who has copied and pasted from other people’s articles on the internet to gain credibility tells the person, “I have this great iron product which will fix your anemia problem.”  The seller doesn’t take into account or probably doesn’t even know that there are many kinds of anemia caused by different nutritional deficiencies or that the patient may be having a life threatening bleed that needs to be seen by a doctor.  Say, if the buyer’s iron deficiency is not the cause of the person’s anemia and it is caused by a cobalamin or folate deficiency or some other nutritional deficiency and the buyer’s iron level is actually normal.  What happens now?  The trusting buyer takes the extra iron.  We know the buyer’s anemia is not corrected.  In the course of weeks or months, the buyer starts to begin exhibiting symptoms of iron toxicity such as vomiting, diarrhea, lethargy, loss of body hair, joint diseases, chronic infection, liver failure, and internal bleeding.  Would you like to be that buyer?  I wouldn’t.

Let me give you one more example.  Say, if another buyer asks the same seller,” I have osteoporosis (brittle bones).”  The seller says, “I have this calcium supplement which is great for bones!”  The buyer agrees and purchases and takes the calcium.  In this case, the buyer and seller are not aware of the need for vitamin D, vitamin K2, and magnesium are also needed in order for the calcium to go to the bones.  Without proper direction calcium can deposit in arteries increasing the risk of heart attack and stroke.  Now, when taking calcium, Vitamin D, Vitamin K2, and magnesium it needs to be given in the proper ratios as well.  So, as you can see it is not as simple as just giving someone calcium.  Again, would you like to be that buyer?  You, already know our answer.  I can give you plenty more examples, but I think these two have gotten our point across.

As you can see the seller just wants to know enough to sound convincing to attract as many buyers as possible.  To the seller, business is business.  There is a saying that goes, “A little knowledge is a dangerous thing.”  However, as you can see, the seller lacks the proper knowledge to suggest an appropriate product to the buyer.  Yes, there are at times the seller is correct, the symptoms are not so severe, or there is no beneficial or harmful effect.  Nevertheless, a broken clock is always correct twice a day. 

通过阅读我们仔细研究的文章,表明您正在花时间,积极的对待您的健康。 我们赞扬你采取措施对待您的健康。 因此,出于对您的安全和健康的考虑,请始终谨慎考察维生素,矿物质和补品的销售者知识。 如果你告诉他们你有一些健康问题,他们简单问一问就说这些产品对你的疾病有好处,而不是要求你提供更多的信息。 你作为潜在的买家要小心了,非常小心。

By reading our articles which we carefully research, it shows that you are taking the time and have an active interest in your health.  We applaud you in taking control of your health.  So, out of concern for your safety and health, always keep in mind what knowledge the seller of vitamins, minerals, and supplements has.  If you tell them that you have a certain problem and they state this is good for it without asking for more information than just the basics.  You as the potential buyer beware, be very very careful.

Please be very discerning about who you buy products from. 

We wish you continued great health.



那么什么是维生素A?/ So what is vitamin A?


它是脂溶性维生素之一。 这意味着需要摄入脂肪才能吸收它。 维生素A的两种主要形式是β-胡萝卜素和视黄醇。 还有其他形式。 β-胡萝卜素需要被身体转化为视黄醇才可以使用。 另一方面,视黄醇可以让身体立即使用。


所以,现在你知道维生素A的两种主要形式β-胡萝卜素和视黄醇。 β-胡萝卜素来源于水果和蔬菜等植物。

So what is vitamin A?

It is one of the fat soluble vitamins.  This means one needs to consume fat in order to absorb it.  Two main forms of Vitamin A are beta-carotene and retinol.  There are other forms as well.  Beta-carotene needs to be converted by the body to retinol before it can be used.  On the other hand, retinol can be immediately used.

Which is the best form of Vitamin A?

So, now you know there are two main forms of Vitamin A beta-carotene and retinol.  Beta carotene comes from plant sources such as fruits and vegetables.




Foods high in beta-carotene

  • Bake sweet potato
  • Carrots
  • Dark Green Leafy Vegetables (Spinach, Turnip greens, Beet greens)
  • Lettuce
  • Cantaloupe Melon
  • Butternut Squash
  • Sweet Peppers
  • Dried Apricots
  • Cooked Peas
  • Cooked Broccoli

Conversely, retinol comes from animal sources like liver, eggs, and fish.




所有β-胡萝卜素需要被身体转化才能成为功能性视黄醇。 在至少6单位的β胡萝卜素中,将需要一个完美健康的人才能将其转化为1单位的视黄醇。 这意味着,你必须吃超过2000克(2公斤)的胡萝卜才能获得相同量的维生素A,就好像你吃了85克牛肝一样。 我们大多数人的健康都不完美,更不用说有那么的爱胡萝卜了。


Foods high in retinol

  • Fermented cod liver oil
  • Cod liver oil
  • Animal Live (beef, duck, goose, lamb)
  • Whole milk from grassfed animals
  • Butter from grassfed animals
  • Eggs (yolks) from free range chickens, ducks, goose
  • Cream from grassfed animals
  • Shrimp

All beta-carotene needs to be converted by the body in order to be functional retinol. It would take someone with perfect health at the very least 6 units of beta carotene in order to convert to 1 unit of retinol.  This would mean, you would have to eat over 2000 grams (2 kilograms) of cooked carrots to get the same amount of vitamin A as if you ate 85 grams of beef liver. Most of us are not in perfect health let alone love carrots that much.

Are there any rabbits out there?



Some of those not able to convert properly are or likely to have a deficiency

  • Diabetics
  • Those with thyroid disorders
  • Alcohol users
  • Those with liver diseases
  • Pancreatic enzyme deficiency (Digestive enzyme deficiency)
  • Exposure to toxins (Pesticides, Processed and fast foods)
  • Certain prescription medications
  • Stress (Physical and Mental)
  • Those who have low fat diets or have been on low fat diets
  • Digestive problems (Many people have poor digestion nowadays)
  • Gallbladder problems
  • Infants (carrots aren’t going to provide sufficient vitamin A for a baby)
  • Vegan or Vegetarian diet



So, if I lack vitamin A what could happen?

  • Vision disorders such as night blindness
  • Thyroid disorders
  • Poor Immune system
  • Mood disorders
  • Skin disorders (Acne, eczema)
  • Infertility
  • Hormone Imbalances







总之,维生素A对身体正常运作非常重要。首先,确保您从您的饮食中获得维生素A(最好是动物来源),如果需要额外的维生素A,最好是从全食物提取出来的。确保您获得足够的锌,脂肪,维生素D,维生素K2和镁,这一点很重要,因此您的身体可以充分利用您的饮食中的维生素A。避免所有合成形式的维生素A,并留意您的膳食维生素A的 摄入量和补充剂维生素A的摄入量。

So, I have heard that too much vitamin A can be toxic.

Well it can be if you a synthetic form of vitamin A.   Additionally, always be mindful of your dietary and supplemental intake as well.  The safest forms of vitamin A are from your diet and from whole food sources which are vitamins made from foods rather than vitamin A or beta-carotene made in some laboratory.  Synthetic vitamin A (common in cheap vitamins) is quite toxic as synthetic beta-carotene has been linked to an increased cancer and heart disease risk in those who smoke and drink alcohol

Signs of vitamin A toxicity include:

  • Bone loss
  • Confusion
  • Hair loss
  • Liver damage

In order for vitamin A to be used properly you need to keep in mind the following

  • Needs zinc to help your vision
  • Needs fat to be absorbed
  • Needs vitamin D
  • Needs vitamin K2
  • Needs magnesium

In conclusion, vitamin A is very important for the body to function normally. First and foremost, make sure you get your vitamin A from your diet (preferably animal sources) and if you need additional vitamin A it is best to get it from whole food supplements. It is important to make sure you get sufficient zinc, fat, vitamin D, vitamin K2, and magnesium, so you your body can fully make use of the vitamin A in your diet. Avoid all synthetic forms of vitamin A and watch your dietary and supplemental intake of vitamin A.

So are you getting enough vitamin A?
