The Truth in Labeling Campaign was incorporated in 1994 as a nonprofit organization dedicated to securing full and clear labeling of all processed food. We are an all-volunteer group funded entirely through donations. Neither our staff nor our directors are paid. We rent no offices, and we use no professional fund raisers. Even the cost of disseminating information is primarily borne by volunteers. Our activities, many described in our website at:, have included visits to congresspersons and scientists, attendance at food industry meetings, testimony before representatives of the U.S. Food and Drug Administration (FDA), and filing a lawsuit against the FDA. But more importantly, we have been making information on the toxic potential of MSG and where it is hidden in food, pharmaceuticals, cosmetics, dietary supplements, pesticides and fertilizers and vaccines, available to consumers. This organization was founded by Jack Samuels, a health care professional who had an acute, life-threatening sensitivity to MSG, and Adrienne Samuels, an experimental psychologist by training with expertise in research design, methodology, and statistics. Both had the skills needed to understand the science underlying Jack’s life-threatening sensitivity, along with the ability to distinguish between the fact of his sensitivity and the fiction generated by those who profit from the manufacture and sale of MSG. Adrienne possessed the knowhow to recognize design flaws in research reports – including those research reports that claimed to have found that MSG is “safe.” The first (and ongoing) project of The Truth in Labeling Campaign (TLC) was to secure identification of processed free glutamic acid (MSG) whenever and wherever it occurs. For over 30 years, concerned consumers have tried to work with the FDA to resolve this identification issue, but have found no evidence that the FDA is ever going to act on their behalf. It appears that only through a true grassroots effort might the FDA's refusal to require labeling of MSG be resolved. It was with this in mind that the TLC joined with 29 petitioners, whose ranks included physicians, researchers, and parents acting on behalf of their MSG-sensitive children, to file a Citizen Petition asking the FDA to require labeling of all MSG found in processed foods. The Citizen Petition was followed by a lawsuit that the FDA easily had set aside. The FDA had only to invoke the Administrative Procedures Act (APA), which allows agencies of the U.S. government to tell the court what material it may or may not look at. Through use of the APA, the FDA was able to withhold evidence contained in its own files that testifies to the fact that MSG has toxic potential.
