After seeing the thread about benzene in sodas due to decarboxylation of benzoate, I was curious what people thought about the negative effects of MSG and phenylalanine/aspartame. I have heard many things such as increased levels of these compounds in the bloodstream can have bad effects, and at the same time I've heard that it is entirely innocuous. So, what do you biochemists/chemists/biologists/random people have to say about this? To give the thread some direction, I'll say that you should keep these questions in mind:
Do any of these two substances, which are very common in many foods, pose a health risk to an average consumer of them?
If you believe one or both are a health risk, to what extent?
An example link that I can make fun of: http://www.nomsg.com/
A quote from the above link:
"MSG actually tricks your brain into thinking the food you are eating tastes good." To me, this seems a bit...well...off the mark.
If anyone has relevant inks of a scientific nature regarding the subject , I would greatly appreciate seeing them
My opinion, based on the reading and studying I have done, is that none of the 2 aforementioned substance pose any harm in the amounts in which they will typically be ingested. Of course, taking enough of anything will have a negative effect, but I think that short of eating the substance pure, you would have a difficult time reaching a harmful/lethal dose.
Ok sorry I have to make fun of one more site: http://www.msgmyth.com/
apparently ingesting any MSG at all can cause 32 (count them! 32!) distinct symptoms from sleep disorders to fatigue to Alzheimer's, MS, fibromyalgia, and parkinson's! Man, this stuff gets around!
