Which statement best describes a vegan diet?

A vegan diet is best described as one in which a person does not consume any animal products. This includes not only meat, but also dairy, eggs, and sometimes even honey, depending on the individual's strictness regarding their dietary choices. The focus of a vegan diet is often on plant-based foods, including fruits, vegetables, grains, legumes, nuts, and seeds.

The other options do not accurately reflect the nature of a vegan diet. Someone who eats meat clearly does not adhere to a vegan lifestyle, as it involves the consumption of animal products. Descriptions about enjoying cheap food or being always full do not provide any insight into the dietary restrictions or philosophy surrounding a vegan diet, focusing instead on personal experiences or characteristics that are unrelated to the definition of veganism. Thus, the statement that a vegan is a person who eats no animal food captures the essential essence of what a vegan diet entails.
