Does anyone else get these? I've found that any free-glutamate food causes me to twitch (in moderate doses) and fatigue (in high doses)
The worst offender so far was a packet of chips (yeast), and a very MSG-laden Italian restaurant meal.
I realize that the mayo-MSG myth is half based off racism, but I think there's a kernel of truth, which is that too much free-glutamate just causes cellular excitation. Meaning the cell is expending energy faster than it can create it.
Are you sure it simply isn't an electrolyte imbalance? Tomato paste usually has a lot of salt, as with soy sauce. Too much salt can cause twitching. Too little salt can cause it. Too much potassium and too little as well. In fact, pretty much any electrolyte that is tied to your muscles will cause it. Dehydration can cause it too.
If you're on any anti-depressants that mess with serotonin, it can cause twitching as it's the neurotransmitter used for fine muscle movement.
100% sure because other much saltier foods don't do it. No medications either
