Can MSG cause asthma attacks?
No. Research results have consistently failed to implicate MSG in causing or exacerbating asthma attacks. Most recently, in 1999, researchers at the Scripps Clinic and Research Foundation found that none of their patients, including those who believed they were sensitive to MSG, experienced asthmatic attacks or any symptoms of asthma in response to either MSG or a placebo. These findings back up the results from an earlier Scripps study, as well those from Harvard Medical School, the National Institutes of Health, the Monash Medical School in Australia and Beth Israel Hospital.
