The fast-food industry is under immense pressure from consumers to offer “cleaner” and healthier menu options. In response, many of the largest chains have been quietly reformulating their recipes to remove controversial and artificial ingredients. These changes often happen without a major national press announcement. The companies will simply pull an ingredient from their supply chain and let the change roll out across the country. This slow but steady detoxification of the fast-food menu is a major win for public health.

1. Artificial Preservatives
Major chains like McDonald’s, Panera Bread, and Taco Bell have all made significant efforts to remove artificial preservatives from their food. McDonald’s, for example, removed artificial preservatives from its Chicken McNuggets. Panera has a long “No-No List” of banned additives that it has worked to eliminate from its entire menu. This is a direct response to consumer demand for food with a cleaner, more recognizable ingredient list.
2. High-Fructose Corn Syrup
High-fructose corn syrup was once a ubiquitous ingredient in fast-food sauces, buns, and soft drinks. Due to its association with a variety of health problems, many chains have quietly replaced it. For example, several years ago, McDonald’s announced it was replacing the high-fructose corn syrup in its hamburger buns with sugar, a subtle but important change for many health-conscious consumers.
3. Artificial Colors and Flavors
The bright, artificial colors that were once a hallmark of fast-food milkshakes and desserts are slowly disappearing. Chains like Burger King and Pizza Hut have committed to removing artificial colors, flavors, and preservatives from their food. This has led to a noticeable change in the appearance of some items, which may now look less vibrant but are made with more natural ingredients.
4. Phthalates and PFAS from Packaging
For years, fast-food wrappers and containers have been a source of controversial chemicals like phthalates and PFAS, which can leach into the food. In response to intense pressure from consumer advocacy groups, major chains like McDonald’s and Burger King have pledged to remove these harmful “forever chemicals” from all of their guest packaging, a major step forward for public health.
5. Trans Fats (from Partially Hydrogenated Oils)
Following the FDA’s official ban on artificial trans fats, all fast-food chains were forced to pull this dangerous, artery-clogging ingredient from their supply chains. This meant that the partially hydrogenated oils that were once used for frying and in baked goods had to be replaced with healthier alternatives. This was one of the most significant and positive public health changes in the industry’s history.
6. Saturated Fats (in Cooking Oils)

Beyond just trans fats, many chains have also moved to healthier cooking oils to reduce the amount of saturated fat in their fried foods. Several years ago, many companies switched from a beef-tallow-based frying oil to a vegetable-based oil. This has been an ongoing process, as chains continue to experiment with different oil blends that offer a better nutritional profile.
7. Antibiotics in Chicken
There has been a massive consumer-led movement to push fast-food chains to stop using chicken that has been raised with medically important antibiotics. In response, nearly every major chain, including McDonald’s, Chick-fil-A, and Wendy’s, has transitioned its chicken supply to be “Raised Without Antibiotics.” This is a critical step in the fight against the growing problem of antibiotic-resistant bacteria.
8. MSG (Monosodium Glutamate)
While the FDA considers MSG to be safe, it has been a source of controversy for decades. To appeal to health-conscious consumers, many chains, particularly in the fast-casual space, have made a commitment to not add any MSG to their food. Chains like Panera Bread and Chipotle have built their brands on this promise of a “clean” ingredient deck.
The “Clean Label” Revolution
The quiet removal of these ingredients from the fast-food supply chain is a direct result of the “clean label” movement. Consumers are more educated and more demanding than ever before. They want to know what is in their food, and they are rewarding the brands that are transparent and committed to using simpler, more wholesome ingredients. This trend has forced the entire industry to clean up its act, one ingredient at a time.
