There’s a decent chance that whatever you’re snacking on right now — or whatever’s sitting in your pantry waiting for you later — contains ingredients that other countries banned years ago. Ingredients linked to cancer. Ingredients that the United States is only now getting around to doing something about.
This isn’t some fringe conspiracy from a guy selling supplements on YouTube. Multiple states are passing actual laws to ban specific additives found in some of the most popular snack foods in America. And a growing pile of research is making it harder to ignore the connection between what we eat every day and our cancer risk.
Let’s talk about what’s actually going on.
California Started It With the So-Called Skittles Ban
California passed a law targeting four specific additives: brominated vegetable oil, potassium bromate, propylparaben, and Red 3. All four have been linked to cancer, thyroid problems, and behavioral issues in children. The law goes into effect in 2027, giving food companies time to reformulate their products.
And California isn’t alone. New York, Pennsylvania, Illinois, New Jersey, and Missouri are all looking at similar bans, targeting a total of 13 additives that have raised health red flags. The fact that multiple states are moving in the same direction at the same time tells you this isn’t a political stunt. There’s real pressure building.
The embarrassing part? These additives have been banned across most of Europe for years. The same Skittles and M&Ms you buy at a gas station in Ohio are sold in London and Berlin — but with natural colorings instead of synthetic dyes. Same taste. Fewer carcinogens. Cool.
Red Dye No. 3 Finally Got the Boot From the FDA
In January 2025, the FDA officially banned Red Dye No. 3 — a petroleum-based chemical used to color food and drinks. This was a long time coming. The FDA had already banned it in cosmetics after scientists found links to cancer in animals. But for decades, it was still perfectly legal to put it in the food you eat. Makes sense, right?
According to the FDA, Red Dye No. 3 is a known animal carcinogen, meaning it caused tumors in rats during lab studies. Companies now have two years to reformulate their products and remove the dye. If they don’t, those products get pulled from shelves. Many snacks have already been discontinued in 2025 as a result.
It took an absurdly long time for this to happen, but it happened. And it’s shaking up the snack aisle.
The Artificial Dyes in Your Cereal Are a Whole Separate Problem
Red 3 gets the headlines, but it’s not the only artificial dye raising alarms. Lucky Charms, Froot Loops, and Trix all use Yellow 6, which has been linked to adrenal tumors in laboratory studies. Those same cereals are sold in Europe with natural coloring instead.
Then there’s Red 40, found in Skittles, M&Ms, and Sour Patch Kids. Red 40 contains benzene — a chemical linked to blood cancers. In Europe, any product containing Red 40 must carry a warning label. In the U.S., you just eat it and hope for the best.
Even Gatorade and Pedialyte use artificial colors to create those signature bright blue, orange, and red drinks. Products designed for athletes and sick kids, loaded with dyes that other countries won’t allow without a warning.
The frustrating thing is that companies like Mars, PepsiCo, and General Mills already know how to make these products without synthetic dyes. They do it every day — just not for us.
Ultra-Processed Foods and Colorectal Cancer in Younger Adults
Here’s where things get really uncomfortable. A recent study reported by NPR found that women who eat a lot of ultra-processed foods were 1.5 times more likely to develop pre-cancerous polyps before the age of 50 compared to those with healthier diets. Those polyps are the first step toward colorectal cancer.
This matters because doctors have been watching colon cancer rates climb in adults in their 30s and 40s for years without a clear explanation. This research points squarely at diet — specifically, the packaged, shelf-stable, ingredient-heavy foods that make up a huge chunk of what Americans eat.
Ultra-processed foods include potato chips, cookies, packaged snack bars, ready-to-eat meals, and basically anything designed to sit on a shelf and taste amazing without any prep. Prior research has also linked soda and other sugar-sweetened drinks to colorectal cancer. Dr. Ben Schlechter of the Dana-Farber Cancer Institute says diet is clearly one of the factors driving the increase, even if researchers are still working out all the details.
A British Study Found Ultra-Processed Foods Raised Cancer Risk Across the Board
A large study involving nearly 200,000 participants in the UK found that every 10% increase in ultra-processed food in someone’s diet raised their average risk of 34 types of cancer by 2% — and ovarian cancer risk by 19%. In a country like the United States, where ultra-processed foods make up close to 60% of total calories consumed, those numbers are alarming.
Dr. Marisa Moroney, a gynecologic oncologist at the University of Colorado, noted that while the ovarian cancer numbers stood out, the bigger takeaway is about inflammation. Ultra-processed foods may trigger inflammatory processes in the body, and chronic inflammation has long been associated with cancer development. There’s also a well-documented chain: ultra-processed foods lead to weight gain, and excess body weight raises cancer risk for multiple types. It’s not one thing — it’s a cascade of bad outcomes that start with what’s on your plate.
Specific Preservatives Are Now Under the Microscope Too
A large tracking study from Sorbonne University looked at 105,260 participants over an average of 7.5 years and examined 17 individual preservatives. While preservatives overall didn’t show a link to cancer, several specific ones did.
Potassium sorbate — used in wine, baked goods, cheeses, and sauces — was linked to a 14% higher risk of overall cancer and a 26% higher risk of breast cancer. Sulfites showed a 12% increased risk of overall cancer. Sodium nitrite, commonly found in processed meats, was associated with a 32% increased risk of prostate cancer. Potassium metabisulfite, used in winemaking, was linked to a 20% increase in breast cancer risk.
Over the 7.5-year study period, 4,226 of the participants developed cancer, including 1,208 breast cancers, 508 prostate cancers, and 352 colorectal cancers. The researchers were careful to note that not all preservatives are bad — 11 of the 17 they studied showed no association at all. But the ones that did show a connection are in foods most Americans eat regularly.
Acrylamide: The Chemical That Forms When You Cook Snacks
This one’s sneaky because you can’t read it on a label. Acrylamide forms naturally when starchy foods are cooked at high temperatures. French fries, potato chips, breakfast cereals, cookies, toast, and even coffee all contain it. The International Agency for Research on Cancer classifies acrylamide as a “probable human carcinogen.” The U.S. National Toxicology Program calls it “reasonably anticipated to be a human carcinogen.” The EPA says it’s “likely to be carcinogenic to humans.”
Three different agencies, three different ways of saying roughly the same thing: this stuff probably causes cancer. To reduce your exposure, you can cook potatoes to a lighter color instead of dark brown, soak raw potato slices in water before frying, and generally limit fried and roasted starchy foods. Boiling and steaming don’t produce acrylamide.
The Hard Numbers on Diet and Cancer Risk
According to the National Cancer Institute, the lifetime risk of being diagnosed with any cancer for men and women in the United States is 39.3%. That’s nearly four in ten people. A 2019 study published in the British Medical Journal found that a 10% increase in ultra-processed food consumption was associated with a 12% increase in overall cancer risk and an 11% increase in breast cancer risk.
The World Cancer Research Fund recommends limiting fast foods and processed foods high in fat, starches, and sugars as a cancer prevention strategy. Their 2018 recommendations are straightforward: fill two-thirds of your plate with vegetables, whole grains, beans, fruits, nuts, and seeds. The remaining third should be lean protein — fish, poultry, dairy, or plant-based options like black beans, lentils, and tofu. Limit red meat to three portions per week, between four and six ounces each.
What Actually Makes Sense Going Forward
Clinical dietitian Alyssa Tatum from MD Anderson Cancer Center put it in a way that’s actually helpful: “It’s not like if you had smoked meats last week at a barbeque that you’re going to have cancer now. It’s not necessarily that one-time exposure. It’s a repeated exposure over time, and that’s the concern, so just try to eat those in moderation.”
Nobody’s saying you can never eat another potato chip. The message from researchers and oncologists is consistent: reduce the frequency, choose smaller portions, and balance the junk with actual food. Swap some of the packaged stuff for whole grains, fruits, and vegetables. If you’re grilling red meat, marinate it first or cook at a lower temperature to reduce carcinogen formation.
The industry push is already happening. Companies are reformulating products rather than lose access to massive markets like California and New York. Some industry groups are fighting back, arguing these state-level bans create confusion and undermine the FDA. But when the FDA itself just banned a dye it admitted was a known animal carcinogen — a dye it let stay in food for decades after banning it from lipstick — maybe the states have a point.
The stuff in our snacks is changing. Whether it changes fast enough is another question entirely.
