A growing number of Americans are buying meat-free foods, with Gallup reporting in 2024 that 4% of U.S. adults identify as vegetarian. But ingredient labels still show that “vegetarian” and “animal-free” are not always the same thing. Here are 10 common foods that look vegetarian at first glance but often include animal-derived ingredients.
Marshmallows often use gelatin
Many marshmallows sold in U.S. grocery stores contain gelatin, which the FDA describes as a protein made from animal collagen. Kraft Heinz’s Jet-Puffed Marshmallows ingredient lists in recent U.S. packaging include gelatin, according to the company label. That means a campfire snack can still contain pork- or beef-derived ingredients.
Gelatin is common because it helps create the soft, springy texture people expect in s’mores and cereal treats. The Vegetarian Resource Group has long listed conventional marshmallows as a food vegetarians should check carefully. Some brands now use carrageenan or starch instead, but standard versions still often rely on animal inputs.
Gummy candies frequently contain gelatin or shellac
Gummy bears, worms, and fruit chews are another frequent surprise because many use gelatin as the setting agent. Haribo Goldbears sold in the U.S. list gelatin on package labels, according to product ingredient statements. Some glossy candies also use confectioner’s glaze, which is commonly made from shellac.
Shellac comes from lac insects, not plants, and it appears in coatings that make candy look shiny on store shelves. The FDA allows shellac in food glazing, and labels may list it as confectioner’s glaze or resinous glaze. A candy can be meat-free in flavor and still not fit a vegetarian diet.
Parmesan cheese can be made with animal rennet
Hard cheeses are one of the biggest label traps for vegetarians, especially Parmesan-style products. The FDA standard of identity for Parmesan permits the use of animal, plant, or microbial enzymes, which means labels may simply say “enzymes.” Traditional Parmigiano Reggiano from Italy is made with animal rennet under consortium rules.
In U.S. supermarkets, some grated or shredded Parmesan products use microbial enzymes, but many do not spell that out clearly. The American Cheese Society has noted for years that rennet source varies by producer. If a package only says enzymes, the source may not be publicly confirmed on the front label.
Caesar dressing usually includes anchovies
Caesar salad sounds vegetarian because it is lettuce, cheese, and croutons, but classic Caesar dressing often includes anchovies. Cardini’s Original Caesar Dressing has listed anchovies on U.S. ingredient labels in recent years, according to product packaging. That small fish ingredient is traditional and gives the dressing its salty, savory flavor.
Restaurant menus do not always note anchovies unless fish is flagged in allergen information or on a full ingredient sheet. The original Caesar salad is widely traced to restaurateur Caesar Cardini in Tijuana, Mexico, in 1924, and anchovies became a standard variation. A meatless salad can still include seafood.
Refried beans sometimes use lard
Refried beans are often treated as a safe vegetarian side, but that depends on the recipe. Traditional Mexican and Tex-Mex cooking has long used lard, which is rendered pork fat, according to standard culinary references and many restaurant ingredient disclosures. Some canned and restaurant versions are vegetarian, but some still are not.
This matters most at restaurants where a bean burrito or combo plate may be ordered as a meat-free meal. Taco Bell states that its U.S. refried beans are vegetarian, but many regional restaurants use house recipes that vary by location. If a menu says only “beans,” the fat source may not be listed.
Pie crust and biscuits can contain lard
Bakery items can look fully plant-based even when the fat is animal-derived. Traditional pie crust recipes in the U.S. have often used lard for flakiness, and some Southern-style biscuits still do the same, according to cookbook standards and bakery ingredient panels. A fruit pie filling can be vegetarian while the crust is not.
Store-bought doughs and frozen pies vary widely by brand. Some labels list lard directly, while others use butter, shortening, or vegetable oils instead. The USDA has long recognized lard as a standard edible fat, and it remains common in certain regional baked goods sold in Texas, Tennessee, and other Southern markets.
Worcestershire sauce commonly contains anchovies
Worcestershire sauce is another hidden fish ingredient that shows up in vegetarian cooking. Lea & Perrins, one of the best-known brands in the U.S., lists anchovies in its ingredient statement. A small amount is enough to affect whether a bloody mary mix, burger sauce, or marinade is truly vegetarian.
Because Worcestershire sauce is used in chili, soups, and pub food recipes, the ingredient can spread far beyond the bottle itself. The product traces back to Worcester, England, in the 19th century, and anchovies remain part of the classic formula. Some vegan versions exist, but conventional ones often still use fish.
Frosted cereals and candies may use gelatin
Not every breakfast cereal is vegetarian, especially when marshmallow pieces or shiny coatings are involved. Several marshmallow-containing cereals sold in the U.S. have historically used gelatin in the marshmallow bits, according to package labels and manufacturer disclosures. That means a cereal sold in the breakfast aisle may still contain animal-derived ingredients.
Candies attached to cereals or snack mixes can also use shellac for shine. The FDA permits shellac and confectioner’s glaze in food coatings, and labels do not always make that obvious to casual shoppers. A cereal can appear meat-free at a glance while including one or two ingredients that change the picture.
Yogurt and desserts may contain gelatin
Yogurt is often grouped with vegetarian foods, but some low-fat yogurts, mousse cups, and pudding-style desserts use gelatin as a thickener. Ingredient lists on certain U.S. dairy desserts have long included gelatin to improve texture and stability. That applies especially to products marketed as creamy, whipped, or extra smooth.
The same issue can show up in cheesecake fillings, sour cream-based desserts, and prepared parfaits sold in supermarket coolers. The National Center for Home Food Preservation also notes gelatin’s role in stabilizing chilled desserts. A dairy-based food is not automatically vegetarian just because it contains no visible meat or fish.
Some chips and snacks use animal enzymes or meat flavoring
Savory snacks can contain animal-derived ingredients even when the front label looks harmless. Cheese-flavored chips may use enzymes from animal rennet, and some barbecue or smoky flavors include chicken fat, beef extract, or dairy cultures, according to package ingredient lists across multiple national brands. The wording can be easy to miss.
Frito-Lay publishes a U.S. list of products that are suitable for vegetarians, which shows not every cheese or seasoned chip makes the cut. Terms like “natural flavors” do not always tell shoppers the source on the front panel. For many vegetarians, the safest guide remains the full ingredient label.
