Most Americans alive today have never tasted a cyclamate-sweetened soda, but their parents almost certainly grew up on them. The foods banned from 1970s America weren’t fringe items or underground curiosities. They were mainstream, heavily advertised, and sitting in virtually every kitchen in the country. Lead-soldered canned goods, petroleum-based red dye in candy, flame-retardant compounds in orange soda – these were not the choices of reckless people. They were the products of an era when the food supply was regulated, just not in the way we’d recognize today.
The timeline between “first red flag” and “actual ban” turns out to be one of the more unsettling things you can learn about American food safety. Several items on this list had documented warning signs in the late 1960s and early 1970s. Some took until 2024 or 2025 to be formally removed. The machinery moved slowly – sometimes because the science was genuinely uncertain, sometimes because the industry pushed back hard, and sometimes because the regulatory process simply works at the pace of continental drift.
Going through this list item by item, the pattern keeps repeating itself. An ingredient becomes standard. Research raises a concern. The industry contests the methodology. Extensions are granted. A state acts when the federal government won’t. Eventually, a ban arrives – and manufacturers who swore the reformulation was impossible complete it within eighteen months. Here is what was perfectly normal to eat in 1970s America, and what happened to it afterward.
1. Cyclamate-Sweetened Diet Sodas
Cyclamate was everywhere in the early 1970s: a low-calorie sugar substitute found primarily in diet soft drinks and canned foods, accounting for a significant share of the artificial sweetener market in the 1960s. It was 30 to 50 times sweeter than sugar and blended well with saccharin, making it the go-to ingredient for anyone trying to cut calories without giving up their soda.
In October 1969, Health, Education, and Welfare Secretary Robert Finch announced that cyclamate posed a cancer risk and would be banned. The trigger was a study in which eight out of 240 rats fed a mixture of saccharin and cyclamate developed bladder tumors – at doses equivalent to humans drinking around 350 cans of diet soda per day. The ban took effect February 1, 1970. According to the FDA’s sweeteners page, the agency continues to prohibit cyclamate and its salts in the U.S. to this day, despite the fact that subsequent reviews found the rat studies were not strong evidence of human carcinogenicity.
Cyclamate remains approved in dozens of other countries but has never been reinstated in the United States, despite multiple petitions to reconsider. The food industry simply moved on to saccharin, then aspartame – and cyclamate became a historical footnote, one of the foods banned from 1970s America that the rest of the world is still happily consuming.
2. Lead-Soldered Canned Goods
The pantry in a 1970s kitchen was stocked with cans: condensed soup, fruit cocktail, creamed corn, canned tomatoes. Early cans were often soldered with high-lead solders, which could and did cause lead poisoning. This was not a secret – it had been a feature of food packaging for most of the 20th century – but the full understanding of how much lead was leaching into the food, and what that was doing to human bodies, took decades to accumulate.
The FDA determined that there was a need to control dietary lead intake, especially for fetuses, infants, and children, because exposure to very low lead levels had been associated with adverse health effects, including learning disabilities, behavioral difficulties, and lowered IQ. The conversion away from lead-soldered cans began gradually in the late 1970s, was completed by the food industry in 1991, and the FDA formally banned the sale of food packed in lead-soldered cans in 1996. The Federal Register’s final rule, published in June 1995, set a compliance date of December 27, 1995 – meaning that by early 1996, lead-soldered canned food could no longer legally be sold in the U.S.
3. Partially Hydrogenated Oils (Trans Fats)
Margarine. Crisco. Microwave popcorn. The frosting on a grocery-store birthday cake. If you ate anything processed in the 1970s, you were almost certainly eating partially hydrogenated oils – a product of an industrial process that turned liquid vegetable oil into a solid fat that was cheap, shelf-stable, and made baked goods feel satisfyingly rich. Manufacturers loved it. Consumers had no reason to question it.
Partially hydrogenated oils, or PHOs, were the primary source of artificial trans fats in processed food for decades. In 2015, the FDA issued a final determination that PHOs are not Generally Recognized as Safe, effectively banning manufacturers from adding them to food products. Compliance deadlines rolled out between 2018 and 2021, and a final rule in 2023 revoked all remaining prior sanctions for PHOs in products like margarine, shortening, and bread. If you check ingredient labels today, you should not find partially hydrogenated oils in any food legally sold in the United States.
Studies found that the trans fats in partially hydrogenated oils raise LDL (bad) cholesterol, decrease HDL (good) cholesterol, and increase the risk of heart disease. The warning signs were visible in research as early as the 1990s, but the full federal ban took another 25 years to complete. That’s a long lag for something sitting in every box of crackers in the country.
4. Brominated Vegetable Oil (BVO)
If you grew up drinking orange soda or certain citrus sports drinks in the 1970s, you were regularly consuming a chemical also used in flame-retardant fabrics and plastics. Brominated vegetable oil, or BVO, was used as a stabilizer in citrus-flavored beverages to keep the flavoring evenly distributed. Without it, the citrus oils would float to the top of the drink. With it, the soda looked smooth and uniform – and you were drinking bromine compounds with every sip.
As NPR reported in November 2023, the FDA had removed BVO from its generally recognized as safe list in the late 1960s but decided there was not enough evidence for a ban. The ingredient stayed in drinks for another five decades while regulators waited for more data. A 2022 study found thyroid damage in rats as a result of BVO exposure, which ultimately led to the FDA’s proposal of a ban. On July 3, 2024, the FDA revoked its food additive regulation for BVO, with the ban taking effect on August 2, 2024.
BVO had already been banned from drinks in Europe and Japan, and major soda makers had begun voluntarily removing it years before the federal action. The U.S. ban, when it finally came in 2024, was catching up to standards the rest of the world had set decades earlier.
5. Red Dye No. 2
Red M&Ms disappeared from store shelves in 1976. No announcement, no explanation – they were just gone, replaced by the now-familiar orange version. The reason was Red Dye No. 2, the most widely used synthetic food coloring in America at the time, showing up in candy, cake mixes, maraschino cherries, breakfast cereal, and soft drinks. Red No. 2 was a synthetic food dye made from petroleum products. In 1969, it was connected to a growing number of tumors in tested rats.
Red No. 2, known generically as amaranth, had been under suspicion for 15 years as being possibly carcinogenic or toxic to the reproductive system. Under existing law, action should have been taken sooner, but extensions were granted. Red No. 2 was finally banned in January 1976.
The dye was quickly replaced by Red No. 40, which is still in use today and has its own critics. Red M&Ms returned to shelves in 1987 using the new formulation. The replacement for a banned ingredient isn’t automatically safer – the regulatory cycle just starts again with a different compound.
6. Red Dye No. 3
While Red No. 2 was banned in 1976, its cousin Red No. 3 managed to stay in the food supply for another 49 years. The bright pink dye, used in maraschino cherries, certain candies, and various medications, had a somewhat bizarre regulatory history: the FDA banned it from cosmetics in 1990 after it was linked to thyroid tumors in male rats, but continued allowing it in food products for decades afterward.
Red No. 3 was finally banned by the FDA on January 15, 2025. Food manufacturers were given until January 2027 to remove it from their products. The gap between the cosmetics ban (1990) and the food ban (2025) is 35 years – a figure that food safety advocates have pointed to as evidence of how slowly the U.S. system can move when industry interests are involved.
7. Potassium Bromate in Bread
This one is still technically legal in the U.S. at the federal level, which makes it unusual on this list – but California banned it as part of the 2023 California Food Safety Act, and the pressure from that state-level action is forcing many national manufacturers to reformulate. In the 1970s, potassium bromate was a standard ingredient in commercial bread and flour – used to make dough rise better, improve texture, and extend shelf life.
Globally, potassium bromate has been banned in countries including the UK, Canada, Brazil, and the EU. The International Agency for Research on Cancer (IARC) and the European Chemicals Agency classify it as “possibly carcinogenic to humans.” The FDA currently limits the maximum potassium bromate concentration allowed in bread to 0.02 μg/g – a restriction rather than a ban.
California’s ban of potassium bromate, along with propylparaben, Red Dye No. 3, and BVO, forced many companies to start reformulating their foods because making different products for California than for the rest of the country is commercially unworkable. Many national bread brands have removed it as a result, creating a de facto phase-out that federal regulators never formally ordered.
8. Saccharin (Temporarily Restricted)
Saccharin was the original diet sweetener – in use since 1879 and wildly popular in the 1970s as cyclamate’s replacement. It was in the pink packets at every diner table, in diet sodas, in canned goods marketed to calorie-conscious consumers. Then the rat studies started coming in. In the early 1970s, saccharin was linked with the development of bladder cancer in laboratory rats, which led Congress to mandate additional studies and require warning labels on saccharin-containing products.
More than 30 subsequent human studies demonstrated that the results found in rats were not relevant to humans and that saccharin is safe for human consumption. In 2000, the National Toxicology Program of the National Institutes of Health concluded that saccharin should be removed from the list of potential carcinogens, and products containing saccharin no longer carry the warning label.
Saccharin was never completely pulled from shelves, but the 1970s scare left an enduring mark on the sweetener market and accelerated the search for alternatives – ultimately driving the development of aspartame. It’s a case where the initial science was real, the panic was probably disproportionate, and the eventual regulatory outcome was a full reversal.

9. Alar-Treated Apples
The apple on your 1970s lunch tray may have looked perfectly red and flawless – almost too flawless. Alar was a growth regulator applied to apple trees in the 1970s and 1980s that kept the apples from falling off the tree too soon. It made fruit more uniform, more visually appealing, and more resistant to bruising during shipping. Farmers loved it. Nobody eating the apple was wondering what was on it.
In 1989, a study from the Natural Resources Defense Council named Alar as one of the chemicals that appeared most frequently in small children’s diets and one that put children at the greatest risk of cancer. The story hit 60 Minutes and triggered a national panic, with schools pulling apple products and apple growers reporting catastrophic losses within weeks.
The manufacturer voluntarily withdrew Alar after the U.S. Environmental Protection Agency proposed banning it based on cancer risk concerns. In 1989, the EPA outlawed daminozide (Alar) on U.S. food crops, though it remained permitted for use on ornamental plants. The Alar episode became a case study in how media coverage and regulatory action can interact – and in how long a suspected carcinogen can stay in the food supply before something is done about it.
10. Chlordane-Treated Crops
If you ate corn, citrus fruit, or root vegetables in the 1970s – and of course you did – there’s a reasonable chance they were grown with chlordane, a pesticide considered highly effective against a wide range of soil insects. Agriculture in corn and wheat, along with household gardens, relied on chlordane during the 1970s. It was applied to lawns, gardens, and fields alike, and most consumers had no idea it was there.
The problem was persistence. Chlordane’s tendency to linger in environmental systems and animal tissues generated widespread concern, and scientific studies connected it to cancer and hormonal disruption, which led to its ban by the EPA. Unlike some of the other bans on this list, chlordane didn’t just disappear from food – it stuck around in soil and animal fat for years after its use ended, because it’s what scientists call a “persistent organic pollutant,” meaning it doesn’t break down easily and accumulates through the food chain.
The EPA banned chlordane for food crops in 1983 and for all uses by 1988. Its legacy in contaminated soil lasted much longer.
11. Safrole: The Original Root Beer Flavor
Real root beer – the kind that tasted distinctly medicinal and herbal, made from actual sassafras root – was already disappearing by the time the 1970s began, but plenty of adults remembered it, and small craft versions were still around. The flavor came from safrole, the essential oil found in sassafras bark. The reason you can’t buy real root beer anymore comes down to that compound specifically – sassafras bark, oil, and safrole are not permitted as a food additive in the United States.
The FDA banned safrole in 1960 after animal studies linked it to liver cancer – so technically it predates the 1970s – but the transition to artificial root beer flavoring was still working its way through the market through much of that decade. Some home brewers continued making traditional root beer well into the 1970s.
Today, root beer is made with various flavorings to mimic that original taste, sometimes using a safrole-free sassafras extract. The safrole itself is gone. What’s in the brown bottle now is an approximation, built from compounds specifically chosen to suggest the flavor without the compound that made it real.
12. Raw Milk
In rural America in the 1970s, raw milk – milk that had not been pasteurized to kill harmful bacteria – was still a fairly common part of life. Farms sold it directly, families in agricultural communities had always drunk it, and a vocal minority insisted it tasted better and had nutritional properties that pasteurization destroyed. In some rural areas, it was simply the norm.
Due to the risk of pathogens like E. coli, salmonella, and listeria, many U.S. states now ban its sale or tightly regulate it. Federal law prohibits the interstate sale of raw milk, though some states permit intrastate sales under specific conditions. The pasteurization requirement became essentially universal for commercial milk, though a committed underground market still exists.
The tension around raw milk has never fully resolved. Proponents still argue that pasteurization eliminates beneficial bacteria along with harmful ones. Regulators point to documented outbreaks. The argument has been going since the 1970s and is still very much alive.
13. Foie Gras
In the 1970s, foie gras – the fattened liver of ducks or geese, produced by force-feeding the birds – was regarded as the height of culinary sophistication in fine American dining. It appeared on white-tablecloth restaurant menus with pride, imported from France, and broadly considered a legitimate luxury food product.
The force-feeding process used to produce it eventually led to bans in California, New York City, and parts of Europe. California banned its production and sale in 2004, the law took effect in 2012, survived a legal challenge, and has remained in force. New York City banned it in 2019.
The foie gras ban is unusual in this list because it wasn’t driven by human health concerns but by animal welfare – the force-feeding process, known as gavage, is considered inhumane by most animal welfare standards. It’s a reminder that food bans don’t always trace back to what’s bad for the eater.
14. Propylparaben in Baked Goods
Propylparaben was a preservative that showed up in packaged baked goods throughout the 1970s – tortillas, muffins, pastries – keeping them shelf-stable for weeks. Most consumers never noticed it on the label, and it had been approved as generally recognized as safe since 1958. The EU banned propylparabens in food in 2006, citing endocrine disruption concerns – meaning the compound may interfere with hormone function in the body. The U.S. FDA took no equivalent action at the federal level.
Propylparaben has been linked to potential health problems including increased cancer risk and nervous system effects. In 2023, California passed the Food Safety Act targeting four controversial ingredients including propylparaben, set to take effect in 2027. As with potassium bromate, the California ban is pushing national manufacturers to reformulate products sold across the whole country, effectively creating a national phase-out without a federal order ever being issued.
15. Tonka Beans and Coumarin
This one is more obscure than the others, but it belongs on any serious list of foods banned from 1970s America. Tonka beans – small, dark South American seeds with a rich vanilla-and-almond flavor – were used in certain European-style pastries and confections that made their way into American specialty food circles. Coumarin is the fragrant compound found naturally in tonka beans, and the FDA classified food containing added coumarin as adulterated in 1954, effectively making tonka beans illegal as a food ingredient in the United States. The ban is codified at 21 CFR 189.130 and is based on coumarin’s liver toxicity at high doses.
Tonka beans are still smuggled into the U.S. by ambitious pastry chefs and sold by some specialty importers in legal gray areas. The ingredient can still be found in cosmetics and perfumes – the ban applies specifically to food – but consuming it in any meaningful quantity raises documented concerns about liver damage. It’s an unusual case where something banned from American grocery stores is perfectly legal to spray on your wrist.
16. Azodicarbonamide in Bread Dough
The 1970s American bread aisle was full of loaves that felt light, springy, and somehow perfect – a texture that owed quite a bit to azodicarbonamide, or ADA, a chemical used to condition dough and improve the rise and structure of commercial bread. Subway’s bread and many other brands used it for decades, and the ingredient was so standard in commercial baking that most people never registered its presence.
ADA is used in the U.S. to whiten cereal flour and improve baking bread dough, but is banned for use in food by the EU, where it is considered a carcinogen. The concern centers on a breakdown product called semicarbazide, which forms when ADA is baked at high temperatures. Studies in rodents have linked it to cancer, though the FDA maintains that the levels in baked products are low enough to be considered safe for human consumption.
You can still find ADA on the ingredient list of certain commercial breads and rolls in the U.S. today, though a number of companies voluntarily removed it following public pressure in the early 2010s. The fact that the same dough additive is a banned substance in Europe and a legal ingredient in American bread is one of the cleaner illustrations of the regulatory gap that food safety advocates keep pointing to.
17. Titanium Dioxide in Candy and Icings
Titanium dioxide was the secret behind those impossibly white frostings, brightly opaque candies, and certain processed desserts that defined 1970s supermarket shelves. It’s a whitening agent – an intensely bright pigment that makes foods look cleaner, more vivid, and more visually appealing. Powdered Donettes, certain candies, some cake icings – many contained it.
The European Food Safety Authority banned titanium dioxide as a food additive in 2022, concluding after reviewing thousands of studies that it could no longer be considered safe because of its potential to damage DNA or cause chromosomal damage at the nanoparticle level. The U.S. FDA has not issued a federal ban, but the EU ban prompted some companies, including the maker of Skittles, to begin phasing it out voluntarily in expectation of future regulatory action.
The ingredient is still found in numerous U.S. products. Its safety assessment in the U.S. has not been meaningfully updated since 1973.
18. Blackcurrants
This last one is the strangest entry – not a processed-food additive, but an actual fruit. Blackcurrants were a staple in 19th-century American gardens and a common ingredient in preserves, cordials, and desserts. By the 1970s, however, they had been effectively banned for decades and most Americans had never heard of them, let alone tasted one.
Blackcurrant plants serve as an intermediate host for white pine blister rust, a fungus that devastates white pine trees, and the U.S. federal government banned the plants in the early 20th century to protect the timber industry. The federal ban was lifted in 1966, but state-level bans persisted in many places through the 1970s and beyond. New York only lifted its ban in 2003. Blackcurrants remain common throughout Europe – they’re the flavor behind Ribena and the purple Skittles sold in the UK – but they’re only just beginning to find a foothold in U.S. markets again. Most Americans still have no idea what they’ve been missing.

The Pattern Behind Every Ban
What’s easy to miss when you go through this list item by item is how consistent the timeline is. An ingredient goes into wide use. Decades pass. Animal studies raise a concern. The industry objects that the doses were unrealistic, or that the research was flawed, or that consumer demand makes change impossible. More time passes. Eventually, either the evidence becomes impossible to ignore or a state acts when the federal government won’t – and then the reformulation that “couldn’t happen” turns out to have been possible all along.
That timeline from first warning to actual ban stretches to 20, 30, even 50 years for some of the items on this list. Red Dye No. 3 sat in food for 35 years after being pulled from cosmetics. BVO spent more than five decades in an ambiguous “interim” regulatory status before anyone formally ended it. That’s not a flaw in the system so much as a description of how the system actually works: cautiously, slowly, and with significant deference to the industries that depend on the status quo.
The 1970s pantry wasn’t full of malicious choices. It was full of products that reflected what was known, what was convenient, and what nobody had yet been forced to change. That’s a useful thing to hold in mind the next time you read an ingredient label and feel reassured by the fact that something is technically approved. Approval, as this list keeps demonstrating, is not the same as safe. It sometimes just means: not banned yet.
