Does Vegan Diet increase life expectancy?

In recent years, veganism has become increasingly popular, with many people choosing to adopt a plant-based lifestyle for ethical, environmental, and health reasons. While the ethical and environmental benefits of veganism are well-established, there is also growing evidence that a vegan diet can have positive health benefits, including potentially increasing life expectancy.

Studies Connecting Veganism and Life Expectancy

Several studies have shown a link between veganism and a reduced risk of death from various causes. A 2017 study published in the journal The American Journal of Clinical Nutrition analyzed 17 previous studies and found that vegans had a 20% lower risk of premature death compared to meat-eaters.

Another study, published in the journal Nutrition, Metabolism and Cardiovascular Diseases in 2013, revealed that vegans had a 15% lower risk of dying from heart disease, the leading cause of death globally.

These studies suggest that a vegan diet may help protect against chronic diseases such as heart disease, cancer, and type 2 diabetes, which are major contributors to premature death.

Possible Mechanisms Behind the Lifespan-Extending Effects

Several factors may contribute to the potential life-extending benefits of a vegan diet:

Reduced Intake of Saturated Fat and Cholesterol: Vegan diets are generally lower in saturated fat and cholesterol, both of which are linked to an increased risk of heart disease.

Increased Intake of Fiber, Fruits, and Vegetables: Vegan diets typically have a higher intake of fiber, fruits, and vegetables, which are associated with a lower risk of chronic diseases.

Lower Body Mass Index (BMI): Vegans tend to have a lower BMI on average than meat-eaters, which is linked to a reduced risk of obesity-related diseases.

Lower Blood Pressure: Vegans may have lower blood pressure, a key factor in reducing the risk of heart disease and stroke.

Improved Gut Health: Vegan diets may promote a healthier gut microbiome, which can contribute to overall well-being and disease prevention.

Considerations for Vegan Diets and Life Expectancy

While the evidence suggests that a vegan diet may increase life expectancy, it is essential to note that not all vegan diets are created equal. To maximize the potential health benefits of a vegan diet, it is crucial to ensure that you are getting all the nutrients you need. This includes protein, calcium, iron, vitamin B12, and omega-3 fatty acids.

Consulting with a healthcare professional or registered dietitian can help you create a well-balanced vegan diet that meets your individual needs.


The available evidence suggests that a vegan diet may indeed increase life expectancy by protecting against chronic diseases such as heart disease, cancer, and type 2 diabetes. However, it is vital to ensure that you are getting all the essential nutrients if you are following a vegan diet. Talk to your doctor to determine if a vegan diet is right for you.

Additional Points to Consider

While a vegan diet may increase life expectancy, it is important to remember that overall lifestyle factors play a significant role in longevity. Regular exercise, stress management, and adequate sleep are also crucial for maintaining good health and living a long and fulfilling life.

A vegan diet can be a healthy and nutritious choice for people of all ages. However, it is especially important for children, pregnant women, and older adults to ensure that they are getting all the nutrients they need.

If you are considering adopting a vegan diet, it is a good idea to talk to your doctor or a registered dietitian. They can help you create a plan that is safe and appropriate for your individual needs.
