Fast food burgers are an easy go-to when you need something quick and tasty. But sometimes, what’s inside those patties and buns can be a little unsettling if you look closely. I’ve come across some sandwiches that make me wonder what exactly went into them.
I want to share with you seven fast-food burgers that include surprisingly unpleasant ingredients you might want to be aware of. Knowing what’s really in your food can help you make better choices—even when you’re craving something fast and convenient.
McDonald’s McDouble with fillers and preservatives
When I look at the McDouble, I like to know what’s inside. Thankfully, it’s made with two 100% beef patties without fillers or preservatives.
The ingredients list is pretty straightforward—American cheese, pickles, onions, ketchup, and mustard on a regular bun. From what I’ve seen, the McDouble doesn’t hide any strange additives or fillers, which is a relief when grabbing a quick bite.

Burger King Whopper packed with artificial flavors
When I looked into the Burger King Whopper, I found it contains several artificial flavors. These are used to enhance taste but often mask chemical additives.
I also saw preservatives like sodium benzoate in the mix, which can raise concerns for some people. While Burger King has started removing many artificial ingredients, the Whopper still packs quite a few.

Wendy’s Dave’s Single with hydrogenated oils
I noticed that Wendy’s Dave’s Single contains hydrogenated oils. These oils are often used in fast food because they help keep the burger fresh longer.
While the beef is fresh and never frozen, the presence of hydrogenated oils adds extra unhealthy fats. It’s something I keep in mind when choosing what to eat. You can learn more about the ingredients on Wendy’s Dave’s Single guide.
KFC Double Down sandwich with processed meat blends
I’ve always been curious about the KFC Double Down. Instead of bread, it uses two fried chicken fillets to hold bacon, cheese, and sauce. The meats come from processed blends, which some people find off-putting.
The mix of processed bacon and chicken gives it a unique texture, but it’s definitely not for those avoiding highly processed ingredients. It’s a bold choice that sparks plenty of debate about what belongs in a burger. For more details on the sandwich’s contents, you can check KFC’s Double Down nutrition facts.
Carl’s Jr. Original Thickburger with added sodium
When I look at the Carl’s Jr. Original Thickburger, I notice the high sodium content right away. This burger packs a lot of salt, which might be a concern for those watching their sodium intake.
The ingredients list includes things like ketchup, mustard, and pickles, which all add to the sodium load. It’s definitely a tasty option but one I’d save for the occasional treat rather than regular meals. You can see more about it here.
Taco Bell’s Crunchy Taco Supreme using fillers
I’ve noticed Taco Bell’s Crunchy Taco Supreme sometimes contains fillers in its seasoned beef. These are ingredients like soy protein or starch to bulk up the meat.
While it keeps costs down, it means you’re not getting just pure beef. For me, that’s a bit disappointing when I want a straightforward taco experience.
Still, the Taco Supreme has its fans, especially with its crunchy shell and familiar toppings. If you want to try making a version at home without fillers, there are good copycat recipes available online. Delish has a popular one.
Jack in the Box Sourdough Jack with questionable additives
I’ve always enjoyed the Sourdough Jack for its crispy sourdough bread and savory flavors. But when I looked closer at its ingredients, I found some surprising additives. The beef patty contains more than just beef—it includes hydrogenated cottonseed oil, corn fiber, and sugars.
These extras aren’t what I expected in a simple burger. While it still tastes good, knowing about these ingredients makes me think twice before ordering. You can check more details about the Sourdough Jack’s ingredients here.
