Defining the Vegetarian Diet
At its core, a vegetarian diet is defined by the absence of meat, poultry, and fish. However, this definition encompasses several sub-types, with the most common being the lacto-ovo-vegetarian, which is likely what most people think of when they hear the term 'vegetarian'.
Types of Vegetarianism
- Lacto-ovo-vegetarian: This is the most common form, where individuals eat a plant-based diet alongside dairy products (milk, cheese, yogurt) and eggs.
- Lacto-vegetarian: This diet excludes eggs but includes dairy products, in addition to plant foods.
- Ovo-vegetarian: This variation includes eggs but excludes all dairy products.
These distinctions highlight that vegetarianism is not a single, monolithic diet. The inclusion of dairy and/or eggs provides more dietary flexibility and can make obtaining certain nutrients, like Vitamin B12, simpler than for vegans.
What is a Vegan Diet and Lifestyle?
In contrast, veganism is the strictest form of vegetarianism and is often considered a broader lifestyle choice. A vegan diet excludes all animal products and by-products, including:
- Meat, poultry, and fish
- Dairy products (milk, cheese, butter)
- Eggs
- Honey
- Other animal-derived ingredients like gelatin, whey, or casein
Beyond the plate, many vegans extend their philosophy to other aspects of their lives by avoiding products made from animals, such as leather, wool, silk, and cosmetics tested on animals. This comprehensive ethical stance is what truly separates veganism from the more diet-focused approach of vegetarianism.
Vegetarian vs. Vegan: A Comprehensive Comparison
To highlight the clear distinctions, the following table compares key aspects of vegetarianism and veganism.
| Feature | Vegetarian (Lacto-Ovo) | Vegan |
|---|---|---|
| Meat, Poultry, Fish | Excluded | Excluded |
| Dairy Products | Included | Excluded |
| Eggs | Included | Excluded |
| Honey | Included | Excluded (for ethical vegans) |
| Nutritional Flexibility | High; dairy and eggs provide easy sources of protein, calcium, and B12 | Lower; requires careful planning to ensure adequate intake of B12, iron, and other nutrients, often with fortified foods or supplements |
| Lifestyle Scope | Primarily a dietary choice | A comprehensive ethical lifestyle avoiding all animal exploitation |
| Environmental Impact | Lighter than omnivorous diets, but still involves animal agriculture for dairy and eggs | Generally the lightest environmental footprint, avoiding all animal agriculture |
Nutritional Considerations for Both Diets
Both diets can be nutritionally sound if properly planned, but they come with different considerations, particularly for key nutrients.
- Vitamin B12: This vitamin is almost exclusively found in animal products. While lacto-ovo-vegetarians can get it from dairy and eggs, vegans must rely on fortified foods (such as plant-based milks and cereals) or supplements to avoid deficiency.
- Iron: Non-haem iron found in plants is less easily absorbed than haem iron from meat. Vegetarians and vegans can improve absorption by consuming vitamin C-rich foods with their meals. Sources include pulses, green vegetables, and fortified cereals.
- Calcium and Vitamin D: Vegetarians consume dairy and eggs, which are sources of these nutrients. Vegans must seek fortified plant-based milks, tofu, and leafy greens for calcium, and rely on fortified foods, sunlight, or supplements for Vitamin D.
- Protein: Both diets can easily meet protein requirements. Plant-based sources include legumes, nuts, seeds, and soy products. Combining different plant foods throughout the day ensures a complete amino acid profile.
The Role of Ethics and Personal Beliefs
For many, the choice between vegetarianism and veganism is rooted in ethics rather than just health or dietary preferences. The core ethical distinction is whether one is comfortable with the use of animals for products like dairy and eggs, or if they oppose all forms of animal exploitation. Some vegetarians believe that consuming dairy and eggs from well-treated animals is acceptable, while vegans view any use of animals for human consumption or products as exploitation. This moral boundary is the fundamental reason behind the strictness of the vegan lifestyle.

Conclusion
The distinction between being vegetarian and not vegan is clear: it revolves around the consumption of animal by-products, with veganism representing the complete avoidance of all animal-derived foods and exploitation. While both are plant-forward and offer potential health and environmental benefits, vegetarianism is a dietary choice with more flexibility, while veganism is a comprehensive ethical stance extending beyond the plate. The path one chooses depends on their personal motivations regarding animal welfare, health, and environmental impact.
