A diet that excludes all animal products is called a vegan diet. This eating pattern focuses solely on plant-based foods, including fruits, vegetables, grains, legumes, nuts, and seeds. Veganism is often pursued for various reasons, including ethical considerations, environmental concerns, and health benefits. A vegan diet can be nutritionally adequate if planned correctly, offering potential advantages like lower cholesterol levels, improved heart health, and reduced risks of chronic diseases. However, attention must be given to essential nutrients like vitamin B12 and iron.
