Why msg is not good

These toxic effects include CNS disorder, obesity, disruptions in adipose tissue physiology, hepatic damage, CRS and reproductive malfunctions. These threats might have hitherto been underestimated. In the meantime, people keep using ever larger amounts of MSG unaware of the possible consequences. Further studies need to be undertaken in order to assess the connection between MSG and cardiovascular disorders, headache, and hypertension in human models. MSG is a controversial food-additive used in canned food, crackers, meat, salad dressings, frozen dinners and a myriad of other products.

It is found in local supermarkets, restaurants and school cafeterias alike. While MSG probably has huge benefits to the food industry, the ubiquitous use of this food-additive could have negative consequences for public health. If more substantive evidence of MSG-toxicity would be provided, a total ban on the use of MSG as a flavour enhancer would not be unwise to consider.

Anecdotal reports started swirling about MSG and the symptoms it supposedly triggered, from headaches and nausea to tightness in the chest. Though there were plenty of anecdotal reports about MSG, scientific evidence was thin.

So in the s, the FDA asked an independent scientific group to investigate. The group concluded that MSG is safe, though they said some sensitive people might get short-term symptoms like headache or drowsiness if they consume 3 grams or more of MSG a typical serving of MSG in food is less than.

In , however, they removed MSG from this list. Learn about some possible causes of headaches here. Historically, some people believed that there was a link between MSG consumption and cancer risk.

However, a systematic review stated that since the s, there have been no studies that have confirmed this link. Learn more about how diet affects cancer risk here. One older study appeared to confirm this.

However, more recent studies — such as one study into the link between MSG, diet, and asthma in adults and one study into MSG and asthma in adults and children — have found no correlation between asthma and MSG consumption. It is also worth mentioning that studies involving high doses of MSG may not be reliable in a real-life setting.

According to the FDA , it is unlikely that a person will consume enough MSG from food to experience any adverse reactions. Learn more about asthma triggers here. One review mentions that some people have reported being hypersensitive to MSG.

The New York Allergy and Sinus Centers have stated that this is a sensitivity rather than an allergy. Symptoms of this may include:. According to the review above, there is not enough solid evidence to confirm that a hypersensitivity to MSG exists.

Despite this, if a person feels that they may have an MSG sensitivity or notices symptoms after eating food containing MSG, they should stop eating it. Keeping a food diary may also help.
