What are the most common health problems vegans suffer from?

Vegans may face certain health issues primarily due to potential nutrient deficiencies. Common concerns include deficiencies in vitamin B12, iron, omega-3 fatty acids, calcium, and vitamin D, which can lead to anemia, bone health issues, and fatigue. Additionally, some vegans may struggle with adequate protein intake if they do not consume a variety of plant-based protein sources. It's essential for vegans to plan their diets carefully and consider supplementation to mitigate these risks.
