According to the Vegan Society, veganism seeks to exclude all forms of animal exploitation and cruelty, meaning many foods are off limits for vegans. Beyond the obvious culprits like meat and dairy, a surprising number of products contain hidden animal-derived ingredients, making label reading a crucial skill for those adopting a plant-based lifestyle.

Quick Summary

A guide detailing the common and unexpected foods and ingredients excluded from a vegan diet. It explains why items like dairy, meat, and honey are avoided, along with lesser-known additives in processed goods like certain candies, baked goods, and even refined sugars.

Key Points

Obvious Foods: Vegans must avoid all meat, poultry, fish, dairy products, and eggs, along with items like honey.
Hidden Ingredients: Many processed foods contain non-vegan additives such as gelatin, casein, whey, and carmine, which are derived from animals.
Refined Sugar: Some refined sugar is processed using bone char, an animal product, making it non-vegan unless specified as organic or beet sugar.
Label Reading is Key: Diligently checking ingredient lists is essential, as many common products like bread, snacks, and juices can contain hidden animal derivatives.
Restaurant and Fining Agents: Be aware of hidden non-vegan ingredients in sauces (e.g., anchovies in Worcestershire) and beverages (e.g., isinglass in some beer and wine).
Ethical Basis: The exclusion of animal products, including honey and other by-products, is rooted in the ethical philosophy of avoiding animal exploitation.

Common Non-Vegan Foods

Adopting a vegan diet requires avoiding all foods of animal origin. This includes the most evident animal products, but also some that may be less obvious, especially when used as ingredients.

Obvious Animal Products

Meat and Poultry: This covers all types of red and white meat, as well as processed meats.
Fish and Seafood: All forms of aquatic life are excluded.
Dairy: Products made from animal milk, such as cheese, butter, yogurt, and cream.
Eggs: Includes all types of eggs and products containing them.
Honey: Considered off-limits by ethical vegans due to concerns about the commercial honey industry and potential harm to bees.

Frequently Asked Questions

Vegans do not eat honey because it is a product of bees and therefore an animal by-product. Ethical veganism seeks to avoid the exploitation of all animals, and the commercial honey industry often involves practices harmful to bees, such as replacing their honey with nutrient-deficient sugar substitutes.

No, not all bread is vegan. While many basic loaves are, some recipes use non-vegan ingredients such as milk, eggs, butter, or honey. Additionally, some commercial breads use L-cysteine, an amino acid often derived from poultry feathers, as a dough conditioner.

Gelatin is a gelling agent made from boiling the skin, bones, and connective tissues of animals like cows and pigs. It is a common ingredient in marshmallows, gummy candies, some yogurts, and various desserts.

Refined white and brown sugar are not always vegan, as they can be processed using bone char, which is made from charred animal bones. Vegans should look for products specified as organic sugar, beet sugar, or explicitly labeled vegan.

Some beers and wines are not vegan because they use animal-derived fining agents like isinglass (fish bladders), gelatin, or casein to clarify the liquid. It is best to check with the manufacturer or look for brands that label their products as "unfined" or "vegan".

It's important to read the label carefully on "non-dairy" products like creamers or cheese. They can sometimes contain casein or whey, which are milk-derived proteins.
