A vegan diet, which excludes all animal products, often lacks sufficient amounts of Vitamin B12. This vitamin is primarily found in animal-derived foods such as meat, dairy, and eggs, making it a crucial nutrient to monitor in individuals following a vegan lifestyle. Vitamin B12 is essential for nerve function, the production of DNA, and the formation of red blood cells. A deficiency can lead to serious health issues, including anemia and neurological problems.

In the context of dietary teaching, it is important for a nurse to emphasize the sources of Vitamin B12 that are appropriate for vegans, such as fortified foods (such as plant-based milks, nutritional yeast, and breakfast cereals) and dietary supplements. Ensuring adequate intake of this vitamin is crucial for overall health and well-being in those adhering to a vegan diet.

The other vitamins listed, such as Vitamin A, C, and E, can typically be obtained through a well-planned vegan diet as they are found in a variety of plant-based foods. Thus, while they are important, they are not as commonly deficient in individuals who practice veganism compared to Vitamin B12.
