Vegetarian diets commonly include which of the following foods?

Vegetarian diets can vary significantly in terms of what they include, but many common variations incorporate dairy products and eggs, which are classified under lacto-ovo vegetarian diets. This approach allows individuals to consume a broader range of foods while still adhering to the principles of vegetarianism. Dairy products provide a significant source of calcium, vitamin D, and protein, while eggs offer high-quality protein and essential fatty acids.

Other options tend to present a more restrictive view of vegetarianism. For example, only consuming fruits and nuts would lack essential nutrients found in grains, vegetables, or proteins from dairy and eggs. Similarly, relying solely on grains and vegetables would not provide enough protein or other nutrients that dairy products and eggs contribute. Lastly, focusing only on legumes and beans would limit dietary variety and may not supply a complete protein profile without the inclusion of other food groups. Thus, including dairy products and eggs in a vegetarian diet supports a more balanced and nutritionally sufficient approach.
