Monosodium Glutamate or MSG. There is some chilling in my refrigerator from last night's Chinese take-out and as I look around my kitchen, I see more..bag of Tostitos, cans of soups, sauces and let's not even go into the freezer! Within past decade or so, MSG has become one of the most popular food additive in our food industry.
MSG is the salt of amino acid-glutamic acid. This glutamic acid is a non-essential amino acid meaning our body is capable of producing it. But the MSG that is synthesized outside the human body is believed to be slightly different and thus has caused so many controversies and confusion among consumers.
It is simply a white powder, by itself has quite an unpleasant taste. When used in desired ratio, MSG is believed to bring different taste profile that is different from four classic taste: sweet, sour,salty and bitter; something called
umami. Food and Drug Administration (FDA) has classified MSG as Generally Recognized as Safe (GRAS) ingredient since 1958.
Although FDA says it is safe for human consumption, there has been many anecdotal reports of adverse reactions to MSG such as nausea, headache, hyperactivity, sweating etc which is also known as MSG Symptom Complex. However, no research have yet found any definitive link between MSG and these symptoms. Due to this reason, FDA requires food companies to list MSG in their label. Therefore, it is very important to read the food label especially if you are sensitive to MSG as our manufacturers are very smart when it comes to labeling.
Some common MSG synonyms are: yeast food/nutrient, anything hydrolyzed/hydrolyzed protein, gelatin, soy protein isolate, sodium caseinate, calcium caseinate
So, whats the big deal with MSG?
Besides the sensitivity to MSG, it is viewed as toxin and is believed to cause many health related issues such as brain damage, asthma, obesity, and diabetes to name a few. As of yet, there are no human studies that have shown conclusive evidence on the ill-effects of MSG.
Most of the food that contains MSG is processed, pre-packaged which also happens to be relatively higher in calories, fats, and sodium. It does not surprise me to see people blaming once again on just one ingredient to cause multidimensional problem of obesity & diabetes.
The amount of MSG that is in our food is safe for human consumption. More long term human research is needed in this area to see if MSG is really as bad as it is believed to be.
BUT, if you are sensitive to MSG, read the labels carefully, and while dining out, request your food to be made without MSG or ask your server for MSG free options. And even if you are not sensitive to MSG, it is always better to use fresh ingredients and avoid frozen, pre-packaged food as much as possible!!
