People are becoming aware of the benefits of switching to a vegetarian diet,
not just for the health reasons,
but also because it plays a vital role in protecting the environment.
Some people go further,
and eat a vegan diet, which excludes all products from animal sources, such as cheese, eggs, and milk.
However, some nutritionists believe that a vegan diet can be deficient in some of the vitamins and minerals that our bodies need daily.
