How does the FDA know MSG is safe? The Glutes tell them so!

The first record of FDA collusion with industry that we have is from September, 1969. At that time, then-FDA Commissioner Herbert Ley presented evidence to the Senate Select Committee on Nutrition and Health, that, he alleged, demonstrated MSG was safe.  Of the four studies presented, two were incomplete and two did not even exist.

Before that time there had been no need for the FDA to have such a cozy relationship with industry in regard to MSG. It was not until 1969 (12 years after the method for MSG manufacture had changed to one of bacterial fermentation), that the first evidence showing monosodium glutamate caused brain lesions and endocrine disorders in experimental animals was published in the journal Science (1).

History buffs can read the sordid history of FDA/industry cooperation here. There are many similar accounts of FDA collusion involving Monsanto (glyphosate and GMOs), the artificial sweetener aspartame, cigarettes, and vaccines.

  1. The FDA allows “monosodium glutamate” to be given as an illustration of
    a common safe food:

    “It is impracticable to list all substances that are generally recognized
    as safe for their intended use. However, by way of illustration, the
    Commissioner regards such common food ingredients as salt,
    pepper, sugar, vinegar, baking powder, and monosodium glutamate
    as safe for their intended use.” (CFR 21 582.1)
