Why should we be concerned about MSG? Well it’s an excitotoxin which means it stimulates your brain cells to damage and even death! Some side effects of MSG include: obesity, eye damage, headaches, fatigue, disorientation, depression, rapid heartbeat, tingling and numbness. Doesn’t sound great right! The worse part is that while it’s added to foods, over 70 names are used for it, and since it’s also made in the processing of heated foods, this processing doesn’t warrant labeling it. So you could be buying food containing MSG and not know it since it’s not labeled so.
