What is the difference between lacto-vegetarian and vegan?

5 min read

According to the Vegetarian Society, a vegetarian is someone who doesn’t eat meat, poultry, or fish, but different types exist. The core difference between lacto-vegetarian and vegan diets is a single, yet significant, category of food: dairy products.

Quick Summary

Lacto-vegetarianism excludes meat and eggs but includes dairy, while veganism is a more restrictive practice that eliminates all animal-derived products, including dairy.

Key Points

  • Dairy is the Deciding Factor: The core difference is that lacto-vegetarians consume dairy products, while vegans do not.

  • Ethical Philosophies Diverge: Veganism extends to a rejection of all animal exploitation, whereas lacto-vegetarianism typically focuses on avoiding animal slaughter.

  • Nutrient Sources Differ: Lacto-vegetarians can get vitamin B12 and calcium from dairy, but vegans must use fortified foods or supplements.

  • Lifestyle Impact: Veganism is a broader lifestyle choice that affects consumer decisions beyond food, unlike lacto-vegetarianism.

  • Planning is Key for Both: Regardless of the choice, a well-planned diet is necessary to avoid nutritional deficiencies, especially on a strict vegan diet.

Understanding the Core Dietary Distinctions

The fundamental separation between a lacto-vegetarian and a vegan diet lies in their stance on animal-derived products. While both diets share a commitment to avoiding meat, fish, and poultry, their rules diverge when it comes to dairy, eggs, and other animal by-products.

The Lacto-Vegetarian Diet Explained

The prefix 'lacto' is derived from the Latin word for milk, which is the key feature of this diet. Lacto-vegetarians consume a plant-based diet, but their plate also includes milk, cheese, yogurt, and butter. They deliberately avoid eating eggs in addition to all meat, fish, and poultry. This approach is often seen as a middle ground, appealing to those who wish to avoid animal slaughter while still benefiting from the nutritional profile of dairy. The inclusion of dairy products makes it easier to obtain certain nutrients, like calcium, phosphorus, and vitamin D, without relying heavily on supplements or fortified foods.

The Vegan Diet Explained

Veganism is a more comprehensive lifestyle choice that goes beyond just diet. Vegans eliminate all animal products and by-products. This means no meat, no poultry, no fish, but also no eggs, no dairy, and often no honey. For many, the motivation for this choice is ethical, based on the belief that all animals should be free from human exploitation. Beyond food, this ethical stance often extends to avoiding non-food items like leather, wool, silk, and cosmetics tested on animals. While a well-planned vegan diet can be very healthy, it requires careful attention to ensure adequate intake of certain nutrients, most notably vitamin B12.

Beyond the Plate: Ethical and Lifestyle Variations

The reasons for choosing either diet are diverse, encompassing health, environment, and ethics. However, the ethical motivations are where the philosophies of vegan and lacto-vegetarian diets differ most significantly.

  • Ethical Considerations: Lacto-vegetarians typically oppose the slaughter of animals for food but may find the consumption of animal by-products like dairy acceptable, provided the animals are treated humanely. In contrast, the vegan philosophy is based on animal liberation and the rejection of all forms of animal exploitation, including the dairy industry.
  • Environmental Impact: Both diets generally have a smaller environmental footprint than a meat-based diet. However, vegans often point to the environmental costs of the dairy industry, including land use and greenhouse gas emissions, as a reason for their more restrictive approach.
  • Lifestyle Extension: For many vegans, the commitment extends beyond food to all consumer choices, impacting clothing, household products, and cosmetics. Lacto-vegetarians, while mindful of their diet, do not typically extend these restrictions to non-food items.

Nutritional Considerations for Each Diet

Planning is essential for both diets to avoid nutritional deficiencies. Here is a breakdown of key nutrients to monitor:

Vitamin B12

Vitamin B12 is almost exclusively found in animal products. Lacto-vegetarians get this vitamin from dairy, but vegans must rely on fortified foods (like nutritional yeast, fortified cereals, and plant-based milks) or supplements.

Calcium and Vitamin D

Dairy products are rich sources of calcium and vitamin D for lacto-vegetarians. Vegans must find alternative sources, such as calcium-fortified plant milks and juices, fortified cereals, and certain leafy greens like kale and broccoli. Adequate vitamin D can be obtained from fortified foods and safe sun exposure.

Iron and Zinc

Both diets rely on plant sources for iron and zinc, but these are less readily absorbed by the body than their animal counterparts. Vegans and lacto-vegetarians can improve absorption by combining iron-rich foods (beans, lentils, tofu, dark leafy greens) with vitamin C sources. Soaking, sprouting, or fermenting grains and legumes can also aid zinc absorption.

Protein and Omega-3 Fatty Acids

Protein needs can be met on both diets by consuming a variety of plant-based protein sources, including legumes, nuts, seeds, and soy products. Both diets, particularly if they don't include fish, may be low in omega-3 fatty acids like EPA and DHA. Vegans need to seek out sources like ground flaxseed, walnuts, and canola oil.

Comparison Table: Lacto-Vegetarian vs. Vegan

Feature Lacto-Vegetarian Vegan
Dietary Inclusions Plant-based foods + Dairy products Only plant-based foods
Dietary Exclusions Meat, poultry, fish, eggs, and products containing them All animal products and by-products (including dairy, eggs, honey)
Core Ethical Stance Typically opposes animal slaughter; may accept humane farming of dairy animals Opposes all forms of animal exploitation and use
Lifestyle Restrictions Generally limited to dietary choices Often extends to non-food items like leather, wool, and animal-tested products
B12 Sourcing Readily available in dairy products Must come from fortified foods or supplements
Calcium & D Sourcing Abundant in dairy products Requires careful planning from fortified foods and other plant sources

Conclusion: Your Journey, Your Decision

Ultimately, the choice between being lacto-vegetarian and vegan depends on an individual's personal ethics, health goals, and commitment level. Both diets offer a path toward healthier eating and reduced environmental impact compared to a traditional omnivorous diet. The primary divergence is the inclusion of dairy, which simplifies nutritional planning for lacto-vegetarians, while vegans take a more expansive approach to animal welfare, which requires more careful nutritional consideration. Regardless of which path you choose, a well-researched and balanced approach is key to thriving on a plant-focused diet. For comprehensive nutritional guidance specific to a vegan diet, authoritative resources like Vegan Health are invaluable.

Making Your Choice: A Step-by-Step Guide

Making the transition to either a lacto-vegetarian or vegan diet can be smooth with proper planning. Start by clearly defining your primary motivation, whether it is health, ethics, or environmental concerns. This will help you set realistic expectations. Next, begin with simple meal swaps, replacing meat with plant-based alternatives you enjoy. Slowly introduce more whole foods like legumes, grains, and nuts. Pay close attention to your body's response and adjust accordingly. Finally, don't be afraid to experiment with new recipes and foods to keep your meals exciting and diverse. Seeking advice from a registered dietitian can be a helpful step to ensure you meet all your nutritional requirements, especially for a vegan diet.

The Difference in a Nutshell

  • Dietary Scope: Lacto-vegetarianism includes dairy products while excluding meat and eggs, whereas veganism is a broader philosophy that excludes all animal products.
  • Ethical Basis: The primary ethical consideration for many lacto-vegetarians is avoiding animal slaughter, while for vegans, it's the broader rejection of all animal exploitation.
  • Key Nutrient Sources: Lacto-vegetarians obtain vitamin B12, calcium, and vitamin D from dairy, whereas vegans must rely on fortified foods or supplements for these nutrients.
  • Lifestyle Impact: Veganism often influences lifestyle choices beyond diet, such as avoiding leather and wool, which is not typical for lacto-vegetarians.
  • Nutritional Planning: Both diets require careful planning, but veganism necessitates a more diligent approach to sourcing certain vitamins and minerals.
