MSG, the Secret Killer Behind the Savor

From the nyt:
“In 1968 a Chinese-American physician wrote a rather lighthearted letter to The New England Journal of Medicine. He had experienced numbness, palpitations and weakness after eating in Chinese restaurants in the United States, and wondered whether the monosodium glutamate used by cooks here (and then rarely used by cooks in China) might be to blame.
The consequences for the restaurant business, the food industry and American consumers were immediate and enormous. MSG, a common flavor enhancer and preservative used since the 1950s, was tagged as a toxin, removed from commercial baby food and generally driven underground by a new movement toward natural, whole foods.
“It was a nightmare for my family,” said Jennifer Hsu, a graphic designer whose parents owned several Chinese restaurants in New York City in the 1970s. “Not because we used that much MSG - although of course we used some - but because it meant that Americans came into the restaurant with these suspicious, hostile feelings.”
Even now, after “Chinese restaurant syndrome” has been thoroughly debunked (virtually all studies since then confirm that monosodium glutamate in normal concentrations has no effect on the overwhelming majority of people), the ingredient has a stigma that will not go away.
But then, neither will MSG.
Cooks around the world have remained dedicated to MSG, even though they may not know it by that name. As hydrolyzed soy protein or autolyzed yeast, it adds flavor to the canned chicken broth and to the packs of onion soup mix used by American home cooks, and to the cheese Goldfish crackers and the low-fat yogurts in many lunchboxes.
It is the taste of Marmite in the United Kingdom, of Golden Mountain sauce in Thailand, of Goya Sazón on the Latin islands of the Caribbean, of Salsa Lizano in Costa Rica and of Kewpie mayonnaise in Japan.
“It’s all the same thing: glutamate,” said Dr. Nuripa Chaudhari of the University of Miami, who was part of the first research team to identify human glutamate receptors.
In September Dr. Chaudhari will take part in the University of Tokyo’s centenary celebrations honoring Prof. Kikunae Ikeda’s 1908 discovery of glutamate flavor. The Japanese company Ajinomoto turned that discovery into crystalline powder form, MSG, and patented it in 1909.
“Just like salt and sugar, it exists in nature, it tastes good at normal levels, but large amounts at high concentrations taste strange and aren’t that good for you,” Dr. Chaudhari said.
If you live in the United States and like spicy tuna rolls, Puerto Rican roast pork or Thai noodles, there is a good chance you are eating, and enjoying, MSG. And if you are the kind of cook who likes to keep a globe-trotting kitchen, well, then, some of these MSG-laden ingredients may deserve a place in your cupboard.
“I don’t cook with MSG because that’s not my training, but it definitely has its place,” said Zak Pelaccio, a New York chef whose ride to fame has been greased with Kewpie mayonnaise. One of the dishes that put him on the map was a sandwich of roasted salmon on pumpernickel bread slathered with wasabi aioli: wasabi from a tube and the mayonnaise.
In regions where meat and meaty flavors have been out of reach for most cooks, MSG has long filled the gap.
“My father called Maggi sauce la segunda venida, the second coming, because he was not a very good cook and it saved him,” said Irma Cecilia Sanchez, a home health aide from Puebla, Mexico, who was waiting in line at a taco truck on the Upper West Side. Maggi sauce is a 19th-century Swiss creation, a general flavor enhancer now made with MSG, sweeteners and extracts.
