Animal-Derived Ingredients (How To Spot And Avoid Them!)

Making the switch to a vegan diet? Amazing! Cutting out meat, dairy, and eggs is a huge first step—one that instantly clears the path toward more compassionate and plant-based eating. But here’s the thing: once those obvious ingredients are out, there are still some sneaky animal-derived additives lurking where you’d least expect them.

The good news? You don’t need to be a food scientist to avoid these hidden culprits. Learning to read labels like a pro is the name of the game. From protein bars to candy to seemingly “dairy-free” options, understanding the fine print can help you keep your cart fully vegan and your meals completely cruelty-free.

This guide breaks down the most common animal-derived ingredients in food, where they’re hiding, and how to spot them. Whether you’re restocking your pantry or navigating a new product aisle, this cheat sheet will make shopping simpler, smarter, and totally plant-based.

Common Animal-Derived Ingredients

Switching to a vegan diet is a big win, but not all animal-derived ingredients are obvious. Many of them hide behind unassuming names on ingredient lists, turning otherwise plant-based foods into unexpected culprits. The key to navigating these sneaky additives? Knowing what to look for.

While this list isn’t exhaustive, it highlights some of the most common offenders you’re likely to encounter. Use it as a guide to shop with confidence, avoid hidden pitfalls, and keep your meals fully plant-based. Let’s begin!

Dairy Byproducts

Dairy byproducts like casein and whey often hide in foods that seem unrelated to milk, including snacks, baked goods, and even “dairy-free” options. These ingredients are widely used as fillers or thickeners, so careful label-checking is essential to avoid them.

Casein

• What it is: A protein found in milk.
• Where it hides: “Dairy-free” cheeses, protein bars, and some processed snacks.
• How to avoid it: Check for certified vegan labels. Be extra cautious with dairy-free cheeses, as some may include casein as a thickener. Look for brands that explicitly state “vegan” on the packaging, such as Miyoko’s or Violife.

Whey

• What it is: A byproduct of cheesemaking.
• Where it hides: Protein powders, baked goods, and some processed snacks.
• How to avoid it: Stick to vegan protein powders like Vega or Orgain and double-check labels on baked goods like cookies and bread. Whey often sneaks into unexpected places, so if you’re unsure, check the ingredient list or the brand’s website for clarification.

Milk

• What it is: The most obvious dairy product, but also the sneakiest.
• Where it hides: Baked goods, soups, chips, or crackers.
• How to avoid it: Opt for vegan certifications and check for alternative phrases like “non-dairy,” which doesn’t always mean vegan. If you see “may contain traces of milk,” don’t worry—this usually refers to shared equipment and not actual ingredients.

Colorants and Coatings

Animal-derived colorants and coatings often lurk in candies, juices, and even fresh produce. From crushed insects to bug secretions, these ingredients might sound unappetizing, but they’re surprisingly common in many shiny or colorful foods.

Carmine

• What it is: A red pigment made by grinding cochineal insects.
• Where it hides: Red candies, fruit juices, and even cosmetics.
• How to avoid it: Look for plant-based colorants like beet juice or turmeric. Brands like YumEarth offer vegan candies without animal-derived colorants, and organic juice brands often avoid carmine altogether.

Shellac

• What it is: A glossy coating made from lac bug secretions.
• Where it hides: Shiny candies and some coated fruits (like apples).
• How to avoid it: Choose uncoated candies or vegan alternatives like Unreal or SmartSweets. When it comes to produce, go for organic fruits, as they typically skip the shellac coating.

Gelatin and Gelling Agents

Gelatin and similar agents are frequently used to give foods their chewy or gel-like texture. Unfortunately, these ingredients are often sourced from animal parts, making them off-limits for vegan diets.

Gelatin

• What it is: A gelling agent made from boiled animal skin, bones, and ligaments.
• Where it hides: Gummies, marshmallows, Jell-O, and sometimes yogurt or ice cream.
• How to avoid it: Opt for vegan gummies and marshmallows made with agar agar or pectin. Brands like Dandies (for marshmallows) and SmartSweets (for gummies) are great swaps.

Isinglass

• What it is: A substance derived from fish bladders used to clarify beer and wine.
• Where it hides: Beer, wine, and sometimes juices.
• How to avoid it: Stick to brands that explicitly label their products vegan, like Barnivore-approved wines. Many craft breweries now list whether their beer is vegan-friendly on their websites.

Fats and Additives

Animal-derived fats and additives like lard and lecithin are hidden in everything from refried beans to chocolate. While some plant-based alternatives exist, these ingredients require extra attention when scanning the label.

Lard

• What it is: Rendered pig fat.
• Where it hides: Refried beans, pie crusts, and some baked goods.
• How to avoid it: Ask about ingredients when dining out, especially at restaurants serving refried beans or pastries. Look for brands like Amy’s or Eden Foods for lard-free canned beans.

Lecithin

• What it is: An emulsifier that can be plant- or animal-based.
• Where it hides: Chocolates, baked goods, and snack bars.
• How to avoid it: Look for lecithin sourced from soy or sunflower, as these are vegan. Egg-derived lecithin can sometimes be labeled as just “lecithin,” so check the brand’s website or reach out if the source isn’t clear. Most major vegan chocolate brands like Enjoy Life or Hu use plant-based lecithin.

Miscellaneous Animal-Derived Ingredients

This category includes unexpected animal-derived ingredients like honey, Vitamin D3, and cysteine. These items may seem harmless but can be tricky to identify without a keen eye for labels. Here’s what to look out for:

Honey

• What it is: A sweetener made by bees.
• Where it hides: Granola, sauces, cereal bars, and baked goods.
• How to avoid it: Look for granolas and baked goods sweetened with agave, maple syrup, or other plant-based alternatives. Many brands, like Nature’s Path, offer honey-free granola. Check out our recipe for vegan honey to keep things sweet.

Vitamin D3

• What it is: Often derived from lanolin (sheep’s wool).
• Where it hides: Fortified cereals, juices, and supplements.
• How to avoid it: Seek out products fortified with D2, or check for vegan D3 sourced from lichen. Brands like Nature’s Path and Ripple are great examples of vegan-friendly fortified foods.

Cysteine

• What it is: An amino acid often derived from animal hair or feathers.
• Where it hides: Commercial bread products (used as a dough conditioner).
• How to avoid it: Choose bread brands that clearly state they’re vegan, like Dave’s Killer Bread. Fresh bakery bread from stores like Whole Foods often skips unnecessary additives—just confirm the ingredient list with the baker.

Stearic Acid

• What it is: A fatty acid sometimes sourced from animal fat.
• Where it hides: Candies, chewing gum, and processed foods.
• How to avoid it: Check for vegan certifications, as stearic acid can also be plant-based. For gum, brands like Simply Gum or PUR are reliable vegan options.

Tips for Reading Labels Like a Pro

Reading labels can feel overwhelming at first, but with a few simple strategies, it gets easier—and even second nature. Knowing what to look for and understanding key terms will save you time and help you confidently spot animal-derived ingredients. Here are some tips to make label reading a breeze:

• Start with vegan certifications. Products labeled as vegan are your best bet for avoiding hidden ingredients.
• Know the buzzwords. Keep an eye out for sneaky terms like “casein,” “rennet,” and “carmine.”
• Check the fine print. Even if a product looks vegan, labels like “may contain traces of milk” don’t mean it’s off-limits. These phrases refer to shared equipment, not actual ingredients.
