You’re standing in the cereal aisle, staring at a box of brightly colored loops. You check the side panel. There it is, tucked away at the very bottom in tiny print: "BHT added to the packaging material to help preserve freshness." Or maybe it's in the food itself. Most of us just shrug and toss it in the cart. We've been told these preservatives keep our fats from going rancid, which sounds like a good thing, right? Nobody wants stinking, oxidized oil in their crackers. But the reality of a list of foods with BHA and BHT is way more complicated than just keeping things fresh.
These two chemicals—Butylated Hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT)—are synthetic antioxidants. They’ve been around for decades. They’re cheap. They work. But they’re also some of the most debated substances in the American food supply. While the FDA generally recognizes them as safe (GRAS), organizations like the Environmental Working Group (EWG) and the International Agency for Research on Cancer (IARC) have raised eyebrows. California even lists BHA as a known carcinogen under Proposition 65. It’s a mess of conflicting data and "maybe" scenarios.
Where These Preservatives Actually Hide
If you’re looking for a list of foods with BHA and BHT, you aren't going to find it on a nice, neat poster at the grocery store. You have to hunt. These additives love fats. They thrive in things that are supposed to sit on a shelf for months without smelling like a wet dog.
Think about potato chips. Those crispy, salty slivers are fried in oil. Oil hates oxygen. To stop that oil from spoiling, manufacturers often spray the inside of the bag with BHT or mix BHA directly into the vat. It’s the same story with "frooty" cereals. You’d think sugar would be the main preservative, but the grains and fats in those flakes need a chemical shield to stay crunchy for a year.
Processed meats are another huge offender. Pepperoni, breakfast sausage links, and even some "pre-cooked" bacon strips use these chemicals to keep the fat from turning grey and smelling funky. It’s honestly kind of gross when you think about how old that meat might actually be.
Then you’ve got the sneaky stuff. Chewing gum. Why does gum need a preservative? Because the gum base often contains fats or waxes that can degrade. Shortening and lard are classic examples, too. If you buy a tub of lard that doesn't need to be refrigerated, there’s a massive chance BHA or BHT is doing the heavy lifting. Even some vegetable oils—the ones sitting in clear plastic bottles under fluorescent lights—rely on these synthetic stabilizers to stay "clear."

The Cereal Situation
Cereal is the biggest category by far. While some big brands like General Mills made headlines a few years ago by removing BHT from their core lineup (think Cheerios), others haven't followed suit. Kellogg’s, for instance, has faced significant pressure but still uses BHT in several popular cereals to maintain that "box-fresh" scent. It’s usually in the liner of the bag, which sounds better, but the chemical is volatile; it migrates right into your breakfast.
The Science That Makes People Nervous
Why do people care? Well, it’s not just "chemophobia." It’s about the studies.
The National Toxicology Program (NTP) has stated that BHA is "reasonably anticipated to be a human carcinogen" based on animal studies. When researchers fed high doses of BHA to rats, mice, and hamsters, the animals developed tumors in their forestomachs. Now, humans don't have forestomachs. That’s the catch. Proponents of these additives argue that the biological mechanism just doesn't apply to us.
BHT is slightly different. It’s not officially labeled a carcinogen like BHA, but it’s often linked to endocrine disruption. Some research suggests it can mimic estrogen or interfere with thyroid signals. In the world of toxicology, the "dose makes the poison." The FDA says we don't eat enough of it to matter. Critics say that because BHT is in everything—from your moisturizer to your dog's kibble to your morning cereal—the cumulative exposure is what we should be worried about.
It's a classic regulatory standoff. You have the European Union, which has much stricter limits on these substances, and then you have the US, where they're basically a staple of the "middle of the grocery store" diet.

Spotting the Culprits on the Label
You’ve got to be a bit of a detective. Labels are tricky. They won't always say "BHA." Sometimes it's buried under "added to preserve freshness" or mixed into an ingredient that itself contains the preservative, which can sometimes lead to it not being listed at all due to "labeling loopholes" for sub-ingredients.
- Dry Cake Mixes: That box of chocolate cake mix has been sitting on the shelf for two years. How? BHA in the fat particles.
- Frozen Sausages: Check the "brown 'n serve" varieties. They are notorious for this.
- Instant Mashed Potatoes: Dehydrated flakes often have BHT to prevent the small amount of fat in the potato from going rancid.
- Dry Soups: Those little flavor packets in ramen or boxed noodle soups are chemical playgrounds.
- Enriched Rice: Sometimes the "enriched" coating includes a preservative.
- Beer: This is a weird one. Some brewers use BHT to stabilize the foam and prevent oxidation, though many craft brewers have moved away from it.
A Note on Cosmetics
Honestly, if you find a list of foods with BHA and BHT, you should probably check your bathroom cabinet too. BHT is incredibly common in lipsticks, eyeliners, and moisturizers. It prevents the oils in your expensive makeup from smelling like old crayons. Since your skin is your largest organ, some experts argue that the BHT you absorb through your skin is just as relevant as the BHT you eat in your crackers.
Why Do Companies Still Use It?
It's all about the money. BHA and BHT are dirt cheap. Natural alternatives like Vitamin E (tocopherols) or rosemary extract exist, and they work pretty well. But they are more expensive. They also have a shorter "protection window." A company using BHT can guarantee a shelf life of 18 to 24 months. A company using rosemary extract might only get 9 to 12 months. In the world of global logistics and massive warehouses, those extra months are worth millions.
Also, BHA and BHT are incredibly stable under high heat. If you're frying chips at 375 degrees, natural antioxidants tend to break down or evaporate. Synthetic ones hold the line. It's a technical "win" for food scientists, even if it's a "maybe-lose" for the consumer.
How to Actually Avoid Them
Look, you don't have to live in a bunker and eat only raw kale. Avoiding these chemicals is mostly about moving away from "ultra-processed" stuff.

First, shop the perimeter. The produce section, the fresh meat counter, and the dairy case rarely contain BHA or BHT. It’s the stuff in the boxes and bags in the center aisles that you have to watch.
Switch to organic brands when you can. The USDA Organic seal prohibits the use of BHA and BHT in food processing. Brands like Annie’s, Cascadian Farm, or Nature’s Path have built their entire business models on avoiding these synthetics.
Check the "Natural" or "Health Food" aisle in your regular supermarket. Even the "house brands" for places like Kroger (Simple Truth) or Whole Foods (365) usually have a policy against these specific preservatives.
Read the "packaging" fine print. Remember, BHT is often in the plastic liner, not the food itself. If you want to be extra careful, look for cereals that come in glass jars or are sold in bulk bins (though bulk bins have their own freshness issues).
The Bottom Line on Your Daily Intake
Is a single bowl of BHT-laden cereal going to kill you? No. Probably not even a thousand bowls. But we live in a world where we are bombarded by "low-level" chemical exposures. Pesticides on our grapes, PFAS in our water, and BHA in our crackers. It's the "body burden" that matters.
If you can easily swap a box of crackers with BHT for a brand that uses Vitamin E, why wouldn't you? It's one less thing for your liver to process. It's one less variable in your long-term health.
The reality of the list of foods with BHA and BHT is that it's shrinking, but slowly. Consumer pressure is the only thing that actually moves the needle. When people stop buying the boxes with the chemical liners, companies magically find a way to use the "expensive" natural preservatives.
Practical Steps to Take Right Now
- Audit your pantry: Spend five minutes looking at the labels of your favorite snacks. If you see BHA or BHT, finish the bag (no sense in wasting money) but look for an alternative next time you're at the store.
- Focus on "The Big Three": Cereal, oils, and processed meats. If you clean up these three categories, you’ve probably eliminated 80% of your BHA/BHT intake.
- Look for Tocopherols: This is just a fancy name for Vitamin E. It's the "good guy" preservative. If you see this on a label, it's a sign the company is trying to avoid the synthetics.
- Support Transparent Brands: Buy from companies that explicitly state they are "BHA/BHT Free." These brands are often more expensive, but you’re paying for the research and the higher-quality ingredients required to maintain shelf life without chemical shortcuts.
- Don't panic: Stress is also bad for your health. If you're at a party and eat a handful of BHT-preserved chips, you'll be fine. Just don't make it a daily habit in your own kitchen.
