Katherine Reid, a Bay Area biochemist with a daughter who was autistic, believes she may have found an antidote to the neurodevelopment disorder - and it's as simple as changing a person's diet. It has become increasingly popular for parents of children with autism or attention-deficit/hyperactivity disorder to turn to gluten- and casein-free, or dairy-free, diets in hopes that it will make a difference. But Reid's diet is different. She thinks what it comes down to, at least for some people with autism, is permanently eliminating just a single chemical compound known as monosodium glutamate, or MSG - an ingredient many people associate with Chinese food. Actually, Reid said, the chemical is in nearly every processed food imaginable, but it only appears on food labels as MSG about 1 percent of the time. Instead, MSG is sometimes labeled as flavor or flavoring, soy protein, barley malt, pectin, corn starch or yeast extract, Reid said. We're getting an abundance of MSG," she said. "It's in 95 percent of processed food. And we don't need it in our diet - ever." While there is no science to back up many of her claims, Reid said the most convincing evidence to her is the results she saw in her daughter. At age 7, Brooke is completely cured, Reid said. [This] persuaded her to quit her high-paying job and help other parents with what she learned, establishing the Fremont nonprofit foundation Unblind My Mind. "Out of the 75 cases of diagnosed autism I've worked on, 74 drastically improved within five weeks," she said.
