Which food type does a vegetarian specifically avoid?

A vegetarian specifically avoids fish because their diet is centered around plant-based foods. The foundation of a vegetarian diet typically includes fruits, vegetables, grains, nuts, and seeds, while excluding meat and fish for ethical, environmental, or health reasons.

While some vegetarians may consume dairy products (lacto-vegetarians) and others may include eggs (ovo-vegetarians), fish is not included in any vegetarian diet. This distinction makes it clear why the avoidance of fish is a key characteristic of vegetarianism.

In the context of the other options, vegetables, dairy products, and grains play a significant role in vegetarian diets, providing essential nutrients and variety. Thus, the correct answer highlights the specific type of food that is excluded from a vegetarian's diet.
