EthicsWhat's the Difference Between Vegan, Vegetarian, and Plant-Based?

Key Points
- 1Veganism is fundamentally an ethical position, not just a diet. It extends beyond food to exclude leather, wool, fur, animal testing, zoos, circuses, and other forms of animal exploitation. The dietary aspect is a consequence of the ethical stance.
- 2Vegetarianism describes a diet that excludes animal flesh but may include dairy products (lacto-vegetarian), eggs (ovo-vegetarian), or both (lacto-ovo vegetarian). It can be motivated by ethics, health, environment, or personal preference.
- 3Pescatarianism includes fish and seafood while excluding other animal meats. This is sometimes called "semi-vegetarian" though this is technically a misnomer since fish are animals.
- 4Plant-based describes a dietary pattern emphasizing whole plant foods. Unlike veganism, it has no inherent ethical component and may include occasional animal products. Some use "whole-food plant-based" (WFPB) to describe a health-optimized version.
- 5Raw veganism is a dietary subset that combines vegan ethics with the belief that cooking destroys nutrients. Foods are eaten uncooked or heated below 104-118°F (40-48°C).
Evidence Summary

|---|---|---|---|
| Vegan | All plant foods | All animal products (meat, dairy, eggs, honey, etc.) | Ethical stance against animal exploitation |
| Vegetarian | Plants, dairy, eggs | Meat, fish, poultry | Varies (health, ethics, environment) |
| Pescatarian | Plants, dairy, eggs, fish/seafood | Land animal meat | Varies (health, environment) |
| Plant-based | Primarily plants | Minimizes animal products | Health-focused dietary pattern |
| Raw vegan | Uncooked plant foods | Cooked foods, all animal products | Health beliefs, subset of veganism |
