How did the way we eat become so unhealthy? Our food system is dysfunctional, all along the chain from farm to fork. The way we eat now is not good for our bodies; it’s not good for our planet. Eating processed and packaged food might be even more risky than most of us realize. In a recent report, NRDC focused on a single legal loophole that allows hundreds, if not more than a thousand, chemical additives in food—those unpronounceable ingredients on the back of the box—to bypass safety review by the Food and Drug Administration (FDA).
When we pick up a package of food at the store--cereal, frozen pizza, chips, an energy drink, a nutrition bar, cake—we assume that everything in it is OK to eat. They wouldn’t be allowed sell it otherwise, right? But because of a giant loophole in food safety law—the “generally recognized as safe,” or GRAS loophole--chemical manufacturers can decide for themselves if the product they’ve created is safe to consume.

Their safety assessments don’t have to be reviewed or approved by anyone else, and often manufacturers don’t even have to disclose the name of the additive, or how it’s used, to the FDA or to the public. Often, the agency isn’t even notified when chemical additives enter our food supply.
All this adds up to a serious lack of oversight into what goes into our food. And that oversight is sorely needed to protect our health. Some additives which manufacturers claimed to be “generally recognized as safe” had been linked to fetal leukemia in human cell tests, or testicular degeneration in animal tests, or, according to FDA scientists, may trigger an allergic reaction in people with peanut allergies.
Despite these potential risks, these additives are already in our food supply. NRDC found these additives listed as ingredients in at least 20 food products.
The FDA can’t do its job and protect public health if it doesn’t know the identity of these chemicals in the first place, or if it can’t review the evidence demonstrating that their use in food is safe.
Ultimately, Congress needs to close the GRAS loophole that allows manufacturers to leave the FDA and the public in the dark about the safety of chemical additives in food. But the FDA can and should move now to end the inherent conflict of interest in the current system for reviewing the safety of chemical additives in food; and when the agency does review a manufacturer’s safety claims, the concerns noted by FDA scientists should be made available to the public.
The widespread use of chemical additives is just one of several deep-rooted problems in our industrialized food system. Our food system encourages the consumption of processed and packaged foods over fresh, healthier, locally grown foods. We end up craving the sugar that sneaks into processed foods, and so we keep buying more of it—and we assume that it’s safe to eat.
The impacts of our food system are chronic, not just in our bodies, but throughout the natural systems that sustain our health and the planet. Our food system encourages food waste on a massive scale—about 40 percent of the food in this country never gets eaten. It gets thrown away, wasting not only the food itself but all the resources that went into producing it, including 25 percent of our fresh water and 4 percent of our oil. Food waste also produces about one-quarter of U.S. methane emissions, making it a source of climate pollution that needs to be addressed.
The industrial livestock operations that produce the vast quantities of meat consumed in this country pollute the air, the water, and our atmosphere. The abuse of antibiotics in the livestock industry—where animals that aren’t sick are fed low doses of antibiotics day after day to try to compensate for unsanitary conditions--risks impairing the effectiveness of these essential medicines when we really need them.
Our industrialized agricultural system relies heavily on the intensive use of chemical fertilizers, herbicides and pesticides, which pose serious threats to human health and wildlife, pollute water, and deplete nutrients in the soil. Excess fertilizer from agriculture is a significant source of global warming pollution. So industrial agriculture adds to climate pollution while also bearing the brunt of its effects, such as extended droughts and heat waves that wither crops in the field, and heavy rains that drown out spring plantings.

We are paying dearly for the way we eat. But while our food system may be unsustainable, it’s not unfixable. By raising awareness of these issues, ensuring that strong, health-protective standards are being enforced by the agencies responsible for protecting the public, not profits, and encouraging business and industry to shift toward more sustainable practices, we can begin to create a healthier, more sustainable food system for all.
