MSG PoisonFound everywhere as an additive in your food, new research has uncovered that this “flavor enhancer” is extremely toxic, causing a battery of adverse health effects within normal dietary ranges.

A new study published in the Journal of Headache Pain reveals that a single intake of monosodium glutamate (MSG) produces headache in the majority of healthy subjects tested.[i]

The researchers conducted a double-blinded, placebo-controlled, crossover study to examine the effect of repeated MSG intake on the following:

 

  • Spontaneous pain
  • Mechanical sensitivity of masticatory muscles (the four muscles that move the jaw laterally)
  • Side effects
  • Blood pressure

The study method was described as follows:

“Fourteen healthy subjects participated in 5 daily sessions for one week of MSG intake (150 mg/kg) or placebo (24 mg/kg NaCl) (randomized, double-blinded). Spontaneous pain, pressure pain thresholds and tolerance levels for the masseter and temporalis muscles, side effects, and blood pressure were evaluated before and 15, 30, and 50 min after MSG intake. Whole saliva samples were taken before and 30 min after MSG intake to assess glutamate concentrations.”

The results were as follows:

  • Headache occurred in 8/14 subjects during MSG and 2/14 during placebo.
  • Salivary glutamate concentrations on Day 5 were elevated significantly (P < 0.05).
  • Pressure pain thresholds in masseter muscle were reduced (i.e. pain increased) by MSG on Day 2 and 5 (P < 0.05).
  • Blood pressure was significantly elevated after MSG (P < 0.040).
  • Tolerance did not develop over 5 days of MSG intake.

Also, a wide range of side effects were observed to occur in much greater frequency in the MSG group, including:

  • Sore Jaw
  • Nausea
  • Fatigue
  • Headache
  • Stomach Ache
  • Dizziness
  • Chest Pressure
