More than 6% of the Italian population identified as vegetarian in 2020, yet the definition of what is a true vegetarian varies widely across cultures and individuals. This article clarifies the distinction by detailing the core dietary exclusions and exploring the different philosophies behind plant-based eating.

Quick Summary

The term 'true vegetarian' can be ambiguous due to varied interpretations. This guide clarifies the different types of vegetarian diets, contrasts them with veganism and pescetarianism, and explains the core principles.

Key Points

  • Core Definition: A true vegetarian is fundamentally someone who abstains from consuming the flesh of any animal, including meat, poultry, and fish.

  • Variations Exist: The term covers different sub-types, such as lacto-ovo (includes dairy and eggs), lacto (dairy only), and ovo (eggs only) vegetarians.

  • Veganism is a Stricter Form: Veganism is the strictest form of vegetarianism, excluding all animal products and byproducts, like dairy, eggs, and honey.

  • Motivations Vary: Reasons for adopting a vegetarian diet are diverse, including ethical concerns for animal welfare, health benefits, environmental impact, and religious beliefs.

  • Nutritional Planning is Key: Regardless of the type, a well-planned vegetarian or vegan diet is necessary to ensure adequate intake of nutrients like vitamin B12, iron, and calcium.

  • Lifestyle vs. Diet: While vegetarianism focuses on diet, veganism extends to a lifestyle choice, avoiding animal products for food, clothing, and other purposes.

The Foundational Principle of Vegetarianism

At its core, the definition of a true vegetarian is a person who abstains from consuming the flesh of any animal, including red meat, poultry, and fish. This means that while plant-based foods form the foundation of their diet, the exclusion of meat is the defining characteristic. However, the term's meaning diversifies when considering other animal-derived products, such as eggs and dairy, leading to different subcategories of vegetarianism. The most common form in many Western countries is the lacto-ovo vegetarian, who includes both dairy and eggs.

The Common Types of Vegetarian Diets

Understanding the various forms is key to grasping the spectrum of what a true vegetarian can entail. These categories are often defined by which animal byproducts are included or excluded:

  • Lacto-Ovo Vegetarian: The most widely recognized type, this diet excludes meat, poultry, and fish but includes both dairy products and eggs.
  • Lacto Vegetarian: This dietary pattern excludes meat, poultry, fish, and eggs but includes dairy products like milk, cheese, and yogurt.
  • Ovo Vegetarian: This diet avoids all animal flesh and dairy products but includes eggs.
  • Vegan: While often considered a form of vegetarianism, veganism is stricter, excluding all animal products and byproducts, including meat, poultry, fish, dairy, eggs, and often honey. Vegans are also considered 'true vegetarians' in the strictest sense of avoiding all animal products.

Why a Pescatarian is Not a True Vegetarian

A common misconception is that people who eat fish but not other meat are vegetarians. This is incorrect. A pescatarian is a separate dietary choice, and the Vegetarian Society has long maintained that vegetarians do not eat fish. Fish are animals, and abstaining from animal flesh is the fundamental principle of vegetarianism. The term 'pescetarian' was created to specifically describe this diet. Therefore, anyone who includes fish or seafood in their meals cannot accurately be called a true vegetarian.

Ethical and Health Motivations Behind the Diet

People adopt a vegetarian diet for a wide range of reasons, and these motivations can shape what 'true' means to them personally.

  1. Ethical Motivations: Many vegetarians choose their diet out of respect for sentient animal life, opposing the act of killing animals for food. This can also extend to concerns over factory farming conditions and the overall exploitation of animals. Ethical considerations are a powerful driving force behind dietary choices.
  2. Health Reasons: A vegetarian diet, particularly a well-planned one, can offer numerous health benefits. Studies have shown they are often lower in saturated fat and cholesterol, while being higher in fiber and certain vitamins. Health-motivated individuals may focus on the nutritional aspects of their food, but they still adhere to the fundamental rule of avoiding meat.
  3. Environmental Concerns: The environmental impact of meat production, including land use and greenhouse gas emissions, motivates some individuals to adopt a vegetarian diet. By reducing or eliminating meat consumption, they aim to lower their ecological footprint.
  4. Religious or Spiritual Beliefs: For many, vegetarianism is a deeply ingrained religious practice, such as in certain sects of Hinduism, Buddhism, and Jainism, which promote the principle of 'ahimsa' or non-violence.

Vegetarian vs. Vegan: What's the Difference?

While veganism is a form of vegetarianism, it's a crucial distinction for understanding the 'true' definition in its most expansive form. Veganism is a lifestyle that seeks to exclude all forms of animal exploitation and cruelty, extending beyond just food.

Feature Lacto-Ovo Vegetarian Vegan Pescatarian Flexitarian
Meat/Poultry ❌ Excluded ❌ Excluded ❌ Excluded ✅ Occasionally Included
Fish/Seafood ❌ Excluded ❌ Excluded ✅ Included ✅ Occasionally Included
Dairy Products ✅ Included ❌ Excluded ✅ Often Included ✅ Included
Eggs ✅ Included ❌ Excluded ✅ Often Included ✅ Included
Honey ✅ Included ❌ Excluded ✅ Included ✅ Included
Core Principle No animal flesh No animal products No red meat/poultry Primarily plant-based

Practical Implications for a True Vegetarian

Adopting a vegetarian lifestyle, regardless of the specific type, requires careful consideration. A well-planned diet is essential to ensure adequate nutrient intake. For example, individuals who exclude dairy and eggs may need to pay special attention to their intake of vitamin B12, iron, and calcium. Fortified foods and supplements are often recommended, especially for vegans and ovo-vegetarians. Consulting with a healthcare professional or a registered dietitian is always a good idea to ensure a balanced and healthy approach to eating.

Conclusion: Defining the True Vegetarian

In conclusion, the term “what is a true vegetarian?” is best understood by acknowledging the foundational principle of avoiding animal flesh. While the most common interpretation includes eggs and dairy (lacto-ovo), stricter definitions exist that exclude all animal byproducts. The key takeaway is that a genuine vegetarian diet is a spectrum of eating patterns, all united by the core ethical, health, or environmental commitment to not eating meat. This excludes diets like pescetarianism and flexitarianism, which are fundamentally different despite their plant-forward approach. Ultimately, what defines a true vegetarian is the consistent and principled avoidance of meat, poultry, and fish, with variations in the inclusion of other animal-derived products.
