MSG is not a viable alternative to salt! I represent a community of over 14,000 people that would also agree. I would prefer to take salt over MSG any day! Grill'd are actually trying to provide a healthier alternative and they are going to get slammed on sodium content? I think it is appropriate to look at the bigger picture here.
Most people don't seem to understand the impact that MSG has on the brain, it is an excitotoxin. MSG is an excitotoxin that shrivels and kills brain cells. An excitotoxin is a chemical that causes a brain cell to become overexcited and fire uncontrollably, leading to cell death. I can't say that salt does the same thing!
Common adverse reactions resulting from MSG can also include:
heart palpitations and the list goes on..
There is a common misconception that MSG exists in natural foods. Low levels of glutamates occur naturally in many foods. If you aren’t allergic or intolerant to MSG, eating MSG at these quantities isn’t a problem. At normal levels in our system glutamates allow cells in the brain to communicate with each other.
The issue is when excessive amounts are consumed, the brain cells die. In these normal foods that contain free glutamate, different amino acids compete to get into the brain, so only a little enters the brain. Manufacturers have worked out that MSG can be produced from any food protein by hydrolyzing vegetable proteins, wheat proteins, or milk protein. These excessive amounts at much higher concentrations gets into the brain causing excitotoxic effects.
In comparison to the alternatives at Mc Donald's the Grill'd burgers are much healthier, it depends what your definition of healthy is!
The research that you have referenced appears to be a little skewed and very little reference is given to Russell Blaylock's findings (a neuro surgeon in Excitotoxins the taste that kills). This leads me to question who has funded all the studies referred to in this research paper.
