Immunity: Does a vegan diet make you less likely to get ill?

A vegan diet may help reduce the risk of illness and support a healthy immune system. Research has shown that vegans often have a lower risk of chronic diseases such as heart disease and diabetes, due to the high intake of fibre, fruits, vegetables, and whole grains, and the avoidance of saturated fats and processed meats. Studies have also suggested that plant-based diets may lower the risk and severity of infections, including Covid-19, with vegan diets being associated with fewer symptoms and a lower risk of severe disease.

A healthy vegan diet rich in plant foods provides essential nutrients and compounds that support immune function and reduce inflammation. The gut microbiome, influenced by a diet high in fibre and fermented foods, plays a crucial role in maintaining immunity. While a well-balanced vegan diet is beneficial for overall health, supplements such as vitamin B12, D, and omega-3 fats may be necessary to ensure optimal nutrient intake. Overall, incorporating a variety of plant foods into the diet can help support good health and potentially reduce the risk of illness.
