What the FDA had to say about MSG and asthma:

"A 1995 report from the Federation of American Societies for Experimental Biology (FASEB), an independent body of scientists identifies two groups of people who may develop a condition the report refers to as "MSG symptom complex." One group is those who may be intolerant to MSG when eaten in a large quantity. The second is a group of people with severe, poorly controlled asthma. These people, in addition to being prone to MSG symptom complex, may suffer temporary worsening of asthmatic symptoms after consuming MSG. The MSG dosage that produced reactions in these people ranged from 0.5 grams to 2.5 grams."  "The agency believes that the report provides the basis to require glutamate labeling. FDA will propose that foods containing significant amounts of free glutamate (not bound in protein along with other amino acids) declare glutamate on the label. This would allow consumers to distinguish between foods with insignificant free glutamate levels and those that might contribute to a reaction."

According to Scientific American,  June 2000,  pg 30 "Asthma Worldwide":

Asthma was rare in 1900.  Now it is considered epidemic.  It kills 5,000 Americans yearly, and 180,000 wordwide according to to the World Health Organization.  Asthma is now the most common childhood chronic disease and is associated with obesity.  (See link on this site to MSG and obesity.)  Experts consider this dramatic increase to be a mystery.  Asthma is virtually absent in parts of rural Africa.  It is not considered to be due to genetics.  It is however considered to be due to environment although there is no evidence that outdoor air pollution is an initiating factor.  It is interesting (and unfortunate) to note that inner city poverty is a risk factor.   Asthma mortality in the US is highest in Americans of Puerto Rican and African descent. 

Recent Research from Johns Hopkins on asthma

This next link is a recent research press release from Johns Hopkins linking nervous system stimulation to the immune response and asthma in particular. 


MSG Link?

MSG was only isolated as food additive ingredient at the turn of this century and only found its way into American food after World War II.  MSG is also now quite prevalent in American "junkfood" such as Doritos as well as in a beloved seasoning used by Americans of Puerto Rican descent - Adobo.  It is also found in extremely large amounts in "fast foods" found easily in poor urban centers.

It is well accepted that MSG stimulates nerve cells in the mouth and elsewhere in the body.  Based on the latest information from Johns Hopkins, this is probably why MSG has been proven to induce asthma in certain individuals.

Some more Food for Thought

If only asthma increased since 1900, but not obesity and Type II diabetes, there may be some question about an MSG asthma link.   If only obesity rose and not asthma and Type II diabetes, then there is still a question.  But the fact that all three diseases that are impacted by glutamate rose to epidemic levels only after MSG was added as a separate ingredient to the food supply raises quite a bit of suspicion on the role of MSG in the rise of these three diseases.
