In the context of vegetarian meals, what does the 'Lacto' in Lacto-OVO refer to?

The term 'Lacto' in Lacto-OVO refers specifically to the inclusion of dairy products in the diet. This classification indicates that individuals following a Lacto-OVO vegetarian diet consume not only plant-based foods but also dairy items such as milk, cheese, and yogurt, though they do not eat meat or fish. The combination of 'Lacto' with 'OVO', which refers to the inclusion of eggs, highlights the presence of both dairy and eggs in the diet, distinguishing it from other vegetarian diets that may exclude these animal-derived products.

Understanding this classification is vital for dietary planning and nutrition as it helps identify the specific allowances within a vegetarian diet, ensuring that individuals can maintain balanced nutrition while adhering to their dietary preferences.
