What is a vegetarian diet?

A vegetarian diet is characterized by its exclusion of meat from the eating plan, which aligns perfectly with the chosen answer. People who follow a vegetarian diet often include various plant-based foods such as fruits, vegetables, grains, nuts, and seeds. Additionally, many vegetarians still consume dairy products (like milk, cheese, and yogurt) and eggs, distinguishing these diets from vegan diets that exclude all animal products.

The other options do not accurately describe a vegetarian diet. For instance, a diet that includes all types of meat contradicts the foundational element of vegetarianism, which is the avoidance of meat. A diet consisting solely of fruits and vegetables may refer to a fruitarian diet, which is much more restrictive and not typical of most vegetarians. Lastly, a diet focused on high-protein foods does not specify the exclusion of meat and could refer to various diets that may or may not align with vegetarian principles. Thus, the correct definition highlights the primary characteristic of vegetarianism: the exclusion of meat while allowing other animal products such as dairy and eggs.
