What is a Lacto-Ovo Vegetarian Diet?
The term "lacto-ovo vegetarian" is derived from Latin roots: 'lacto' refers to milk and dairy products, while 'ovo' refers to eggs. This dietary pattern, therefore, excludes all meat, poultry, and fish, but permits the consumption of dairy and eggs. This approach makes it a flexible entry point into vegetarianism for many people, offering a wide array of food choices while aligning with ethical, environmental, or health-related motives. Most people who simply refer to themselves as "vegetarian" are following a lacto-ovo diet, as it's the most widely understood form of the diet in many countries.
Core Components and Food Groups
A well-planned lacto-ovo vegetarian diet is rich in a diverse range of nutrients. The meals are primarily built around plant-based foods, with dairy and eggs providing additional sources of protein, vitamins, and minerals. This inclusive approach means lacto-ovo vegetarians have access to more nutrients typically found in animal products, which can simplify meal planning compared to stricter plant-based diets like veganism.
Foods included in a lacto-ovo vegetarian diet:
- Fruits and vegetables: All varieties are included and form the core of the diet.
- Grains: Whole grains, including oats, rice, barley, quinoa, and wheat products, are staples.
- Legumes: A key source of plant-based protein and fiber, including lentils, beans, chickpeas, and peas.
- Nuts and seeds: Excellent sources of healthy fats, protein, and minerals, such as almonds, walnuts, chia seeds, and flaxseeds.
- Dairy products: This includes milk, cheese, yogurt, and butter.
- Eggs: A versatile source of protein, vitamins, and minerals.
- Healthy fats: Avocados and vegetable oils like olive oil are also included.
Foods and ingredients to avoid:
- Meat (beef, pork, lamb, etc.)
- Poultry (chicken, turkey, duck)
- Fish and seafood
- Meat and fish-derived byproducts such as gelatin, animal rennet, and stock
Comparison to Other Diets

Health Benefits and Nutritional Balance
Research has linked well-planned lacto-ovo diets to numerous health benefits. The high intake of fruits, vegetables, and whole grains contributes to better heart health, lower blood pressure, and a reduced risk of type 2 diabetes and certain cancers. The inclusion of eggs and dairy products is particularly beneficial for providing essential nutrients that can be more challenging to obtain on a vegan diet alone. Eggs are a complete protein source, and dairy offers excellent calcium and vitamin D. However, careful planning is still required to ensure a balanced intake of all necessary nutrients, especially iron, zinc, and B12, which can be lower than in omnivorous diets. While eggs and dairy provide B12, some individuals may still benefit from fortified foods or supplements, particularly if their intake of these animal by-products is minimal.
Tips for Planning a Balanced Lacto-Ovo Meal
Crafting delicious and nutritious lacto-ovo meals involves focusing on variety and balancing different food groups. A great strategy is to build your plate around a plant-based protein source and add plenty of colorful vegetables, whole grains, and healthy fats. Incorporating dairy and eggs can enhance flavor and nutrient density.

For further nutritional guidance, consult reputable resources like the Dietitians of Canada, which provides excellent information for planning a healthy vegetarian diet.
