As cardiovascular diseases (CVD) remain a leading cause of mortality worldwide, dietary interventions have gained prominence in preventive health. A vegan diet, characterized by an abundance of fruits, vegetables, whole grains, and legumes, offers significant potential for reducing CVD risk. Its high fibre and low saturated fat composition promote heart health and provide an alternative approach to traditional CVD management.

Figure 1: The Role of Vegan Diets in Cardiovascular Health
Studies highlight that individuals on vegan diets have lower LDL cholesterol, reduced blood pressure, and improved endothelial function compared to those on omnivorous diets. These benefits are largely attributed to the high fiber intake in vegan diets, which aids in reducing blood cholesterol levels, and the presence of antioxidants, which help reduce oxidative stress. The absence of red and processed meats, known to increase cardiovascular risks, further supports the cardiovascular benefits of a vegan diet.
While vegan diets provide protective effects, ensuring adequate intake of omega-3 fatty acids and vitamin B12 is crucial for heart health. These nutrients are often limited in plant-based diets, so incorporating sources like chia seeds, flaxseeds, and fortified foods, or considering supplementation, can be essential for vegans at risk of CVD. Regular monitoring and dietary adjustments can ensure long-term cardiovascular benefits without compromising nutritional needs.
A vegan diet offers considerable cardiovascular benefits by promoting lower cholesterol levels, reduced inflammation, and improved vascular health. Through careful planning and supplementation, individuals can harness these heart-health benefits effectively, making vegan diets a viable and impactful dietary choice for CVD prevention.
