An open letter to CBS: Please play it again. It’s already in the can. Ed Bradley did it in November 1991.

It was gone over with a fine-tooth comb by your legal department in 1990 and 1991, and Ajinomoto didn’t sue 60 Minutes after the program aired. Actually, Ajinomoto won’t sue anyone who suggests that monosodium glutamate might be toxic. They keep an extremely low profile and don’t want a lawsuit to shine the light of day on their product. Watch Ed Bradley’s program. You’ll notice there was no one from Ajinomoto speaking about the safety of monosodium glutamate. They did, however, have their man at the FDA, Michael R. Taylor formerly of King and Spaulding and Monsanto represent them wearing his FDA credentials.

Although rated by TV guide as one of the two most watched segments of the 1991 year, 60 Minutes hasn’t replayed it or touched a story that might remotely criticize MSG. It would appear that Don Hewitt caved to industry pressure – could it be explained in any other way? And for neither love nor money can you buy a tape of the program from CBS.

But Don Hewitt is gone. The lie that cigarettes are harmless has been exposed. The toxic chemicals used in production of genetically modified products (GMO’s) are literally on trial. In February, 60 Minutes aired “Did the FDA Ignite the Opioid Epidemic?” The time is right for the toxic effects of monosodium glutamate and the other ingredients that contain Manufactured free Glutamic acid (MfG) to be exposed – and for the conversation to begin anew.

Some things have changed. It is now acknowledged that MfG — the toxic ingredient in monosodium glutamate — is an excitotoxin, killing brain cells and wiping out parts of the endocrine system when passed to the fetus and newborn through the diets of mothers who consume it in quantity in processed foods (which is easy enough to do), as well as through breast milk. There is more excitotoxic MfG in our food supply than there was in 1991, and each year more is added. In addition, the body of medical research on the toxic effects of glutamic acid is growing. A pubmed search done on April 12, 2019, produced 2984 studies of glutamate-related toxicity.

Many of the people interviewed in 1991 are gone. But if you chose to do so, you might still find some, especially the children.

John Olney died of cancer recently, a brilliant scientist and humanitarian, working in his laboratory up to the last. Jack Samuels is gone. He provided information on the toxicity of monosodium glutamate to Roz Karson and Grace Dickhaus of CBS, and to Bruce Ingersol of the Wall Street Journal, from 1990 until the story aired in 1991 – information which they were pleased to confirm. Jack died following a heart attack where medical treatment required that he be given pharmaceuticals that contained manufactured free glutamic acid – which caused him to fibrillate non-stop until he died.

So, play it again please. The timing couldn’t be better.
