What’s Truly in Your Food? A Critical Examination of Research, Health Assertions, and Misinformation in the Digital Era
In the current internet-centric environment where platforms like Facebook, MSNBC, and comedian-turned-news-commentator Jon Stewart coexist as popular “news” outlets, the chance to be misled while thinking oneself informed has never been greater. While comedic shows like The Daily Show frequently manage to highlight political absurdities, their charm comes from simplifications—sometimes at the expense of depth, particularly concerning science and public health.
A recent notable instance is Jon Stewart’s well-known critique of Subway, the sandwich franchise, for including azodicarbonamide in its bread. Stewart humorously associated the compound with yoga mats—a joke that garnered laughter but overlooked the distinction between alarming-sounding chemicals and genuine scientific danger.
Examining Chemicals in Context: Is Azodicarbonamide Truly Hazardous?
Azodicarbonamide may evoke an “ick” factor since it is utilized in non-food items like plastics, but that alone does not render it dangerous in consumables. For instance, table salt is employed in the production of industrial-grade chlorine gas, and gypsum is a common element in both drywall and tofu. In regulated amounts—as stipulated by the FDA—azodicarbonamide is deemed safe up to 45 parts per million. Subway’s choice to eliminate it wasn’t based on new scientific findings; in fact, the move was a reaction to public outcry instigated by a food blogger known as “The Food Babe.”
While it is praiseworthy to question the contents of our food, the manner in which we pose those inquiries is equally crucial. The Food Babe’s campaign illustrates an emerging form of consumer activism that significantly leans on emotional influence, scientific inaccuracies, and fear rather than facts. Her critiques often conflate legitimate food safety issues with pseudoscience, resulting in widespread uncertainty about what is genuinely hazardous and what merely appears alarming.
Epichlorohydrin and the Tea Bag Debate
One of the Food Babe’s most referenced pieces addresses the materials used in tea bags, particularly the polymer polyamide-epichlorohydrin resin. This substance solidifies paper so that it doesn’t dissolve in hot liquid—both practical and essential.
Epichlorohydrin, one of the chemicals involved in producing the resin, is indeed a reactive substance of concern, recognized for generating carcinogenic compounds like 3-MCPD under certain circumstances. Nonetheless, in the context of industrial polymer application, it is chemically transformed (i.e., consumed) to yield a completely different polymeric material. Any remaining traces are strictly monitored, and credible scientific evaluations, while cautious, view the overall consumer risk as minimal.
However, this caution merits consideration. One might ask: Should food packaging comply with even stricter safety protocols? Could manufacturers seek superior alternatives like biodegradable polylactic acid tea bags? These questions are worthwhile. But the framing is what counts. The Food Babe’s stance—“Epichlorohydrin is toxic, thus tea bags are hazardous”—enters a widespread logical fallacy: arguing from fear without delving into the specific risk profile, chemical context, or dose-dependent behavior of toxins.
Misinterpreting Chemistry: From Plastics to Preservatives
The same erroneous reasoning arises in discussions regarding synthetic additives such as propylene glycol, often misrepresented by the Food Babe and others as “antifreeze.” While ethylene glycol (a related but toxic substance) is indeed found in antifreeze, propylene glycol is a distinct molecule with significantly safer characteristics. It is commonly utilized in food, pharmaceuticals, and personal care products, recognized as generally safe by regulatory bodies such as the FDA.
Potassium sorbate, another criticized additive, is a naturally occurring compound that functions as a mold inhibitor. Chemically, it’s merely an unsaturated fatty acid—akin to those in any typical cooking oil. Your body processes it just like any other fat. It’s simple to throw phrases like “chemical preservative” around, but more challenging to acknowledge that “chemical ≠ bad,” and likewise “synthetic ≠ unnatural.”
The “Chemical-Free” Myth
Much of the Food Babe’s rhetoric—and that of many food alarmists—rests on the assumption that “natural is good, and synthetic is perilous.” However, nature is replete with toxins and carcinogens: aflatoxins (natural molds on peanuts), cyanide (naturally found in apple seeds), and arsenic (present in groundwater). The dose, as any toxicologist will affirm, determines the toxicity.
Tea bags, vaccines, preservatives, and other contemporary innovations undergo testing, regulation, and—despite imperfections—usually represent beneficial advancements when evaluated through a comprehensive risk-benefit perspective. Regrettably, the public’s understanding often halts at headlines featuring alarming-sounding chemicals, particularly when amplified by influencers leveraging the wish for straightforward solutions in a complicated landscape.
