Which vegetarian diet permits dairy products but excludes poultry, meats, fish, and eggs?

1. Ovo-vegetarian diet

2. Lacto-ovo vegetarian diet

3. Lacto-vegetarian diet

4. Vegan diet

The correct answer is: Lacto-vegetarian diet

The correct choice is the lacto-vegetarian diet, which indeed allows for the consumption of dairy products while specifically excluding poultry, meats, fish, and eggs. This dietary approach is centered around plant-based foods and dairy, meaning that individuals following this diet obtain their protein and other nutrients from vegetables, fruits, grains, legumes, and dairy sources like milk, cheese, and yogurt. Understanding this dietary classification is crucial for recognizing the various ways people can adhere to vegetarianism. While the lacto-ovo vegetarian diet includes both dairy and eggs, and the ovo-vegetarian diet includes eggs but no dairy, the lacto-vegetarian diet strictly focuses on dairy along with plant foods. A vegan diet, in contrast, entirely excludes all animal products, including dairy. Thus, the lacto-vegetarian diet is distinct in its allowance for dairy while limiting the consumption of other animal-derived foods.
