Do People Who Choose To Eat Vegan Live Longer Than Omnivores?

Veganism has gained significant popularity in recent years as people become more conscious of their dietary choices and the impact they have on their health, the environment, and animal welfare. On the other hand, the traditional omnivore diet, which includes a combination of plant and animal-based foods, has been the standard for generations. This article explores the question: Do people who choose to eat vegan live longer than omnivores? Let's delve into the topic and examine the evidence surrounding veganism and longevity.


Veganism is a lifestyle choice that excludes the consumption of any animal-derived products, including meat, dairy, eggs, and honey. In contrast, omnivores follow a diet that includes both plant-based foods and animal products. Both approaches have their merits, but when it comes to longevity, the evidence seems to favor a vegan lifestyle.

Health Benefits of Veganism

One of the main reasons why people opt for a vegan diet is the numerous health benefits associated with it. Research suggests that vegans have a lower risk of heart disease, which is the leading cause of death worldwide. A plant-based diet, rich in fruits, vegetables, whole grains, and legumes, provides essential nutrients and antioxidants that promote cardiovascular health.

Moreover, studies indicate that vegans have a reduced risk of certain types of cancers, including colon, breast, and prostate cancers. The abundance of fiber, phytochemicals, and antioxidants found in plant-based foods may contribute to this protective effect.

Additionally, adopting a vegan lifestyle can lead to lower cholesterol levels. Animal products, particularly those high in saturated fats, can raise cholesterol levels and increase the risk of developing cardiovascular problems. By eliminating these foods and focusing on plant-based alternatives, vegans can maintain healthier cholesterol profiles.

Furthermore, a well-planned vegan diet can support improved weight management. Plant-based diets are often lower in calories and saturated fats, making them a favorable choice for individuals looking to achieve or maintain a healthy weight.

Nutritional Considerations

While veganism offers numerous health benefits, it's important to address nutritional considerations. A balanced vegan diet can provide all the necessary nutrients, but attention must be given to certain key elements. Protein, iron, and calcium are often a concern for those transitioning to a vegan lifestyle.

Protein, an essential macronutrient, is readily available in plant-based sources such as legumes, tofu, tempeh, quinoa, and nuts. By incorporating a variety of these foods into their diet, vegans can meet their protein requirements and support muscle growth and repair.

Iron is another crucial nutrient that can be obtained from plant-based sources like lentils, spinach, fortified cereals, and pumpkin seeds to ensure an adequate intake. However, it's important to note that plant-based iron (non-heme iron) is not as easily absorbed by the body as iron from animal sources (heme iron). To enhance iron absorption, it is recommended to consume vitamin C-rich foods, such as citrus fruits or bell peppers, alongside iron-rich plant foods.

Calcium, essential for strong bones and teeth, can be obtained from plant-based sources like fortified plant milks, tofu, leafy greens, and sesame seeds. Additionally, fortified foods and supplements can provide an extra boost of calcium for vegans who may have higher calcium requirements.

Supplementation is another consideration for vegans to ensure they meet their nutritional needs. Vitamin B12, for example, is primarily found in animal products, so vegans are encouraged to take a B12 supplement or consume foods fortified with this vitamin to avoid deficiency.

Longevity and Veganism

The relationship between veganism and longevity has been a subject of scientific research. Studies have shown that individuals who follow a vegan diet may experience certain factors that contribute to a longer lifespan.

Firstly, a well-planned vegan diet often includes a higher intake of fruits, vegetables, whole grains, and legumes. These foods are rich in vitamins, minerals, fiber, and antioxidants, which have been associated with a reduced risk of chronic diseases and increased longevity.

Secondly, vegans tend to have a lower body mass index (BMI) on average compared to omnivores. Maintaining a healthy weight is crucial for overall health and longevity, as obesity is linked to various chronic conditions, including heart disease, diabetes, and certain cancers.

Moreover, veganism promotes a healthier lifestyle. Many vegans prioritize exercise, stress management, and adequate sleep, which are essential factors for maintaining optimal health and potentially extending lifespan.

Additionally, environmental and ethical considerations associated with veganism can indirectly contribute to longevity. Plant-based diets have a lower carbon footprint and require less water and land resources compared to animal agriculture. By choosing veganism, individuals can support sustainable practices that positively impact the planet and potentially create a healthier environment for future generations.

Potential Drawbacks of Veganism

While veganism can offer numerous health benefits, there are potential drawbacks that individuals should be aware of to ensure they maintain a well-balanced diet.

One concern is the risk of nutrient deficiencies, particularly in vitamin B12, omega-3 fatty acids, and certain minerals like zinc and iodine. Vegans should be mindful of including fortified foods or supplements to meet their nutritional needs adequately.

Proper meal planning is crucial for vegans to ensure they consume a variety of plant-based foods that provide all the necessary nutrients. This may require some education and awareness to create balanced meals that incorporate a wide range of fruits, vegetables, whole grains, legumes, nuts, and seeds.

Addressing concerns about protein intake is another important aspect. While plant-based proteins can meet daily requirements, some individuals may need to pay closer attention to their protein sources and consume a combination of different plant proteins throughout the day to ensure adequate amino acid profiles.

The Omnivore Diet and Longevity

The omnivore diet, which includes both plant-based foods and animal products, has been the standard for many people for centuries. Studies have examined the relationship between omnivore diets and lifespan, shedding light on various factors that may impact longevity.

The quality and quantity of food consumed play a significant role in determining the effects of an omnivore diet on lifespan. Diets that are predominantly composed of highly processed foods, saturated fats, and added sugars have been linked to increased risks of chronic diseases and shorter lifespans. On the other hand, an omnivore diet that emphasizes whole, unprocessed foods, including lean meats, fish, fruits, vegetables,and whole grains, can provide essential nutrients and support overall health.

Processed foods and additives commonly found in omnivore diets can have negative health effects. Excessive consumption of red and processed meats, for instance, has been associated with an increased risk of certain cancers, heart disease, and other chronic conditions. It is important to moderate the intake of these foods and prioritize lean sources of animal protein.

Furthermore, the balance and variety of foods within an omnivore diet are crucial. Including a wide range of fruits, vegetables, whole grains, and lean protein sources can provide essential nutrients and contribute to better health outcomes.

It is worth noting that the lifespan of individuals following an omnivore diet can be influenced by their overall lifestyle choices. Factors such as smoking, excessive alcohol consumption, lack of physical activity, and high stress levels can significantly impact longevity. Adopting healthy habits and making conscious choices regarding food and lifestyle can improve overall health and potentially extend lifespan.


When considering the question of whether people who choose to eat vegan live longer than omnivores, it is essential to acknowledge the potential health benefits of a well-planned vegan diet. The abundance of plant-based nutrients, lower risk of chronic diseases, and focus on a healthier lifestyle contribute to a potential longevity advantage for vegans.

However, it is crucial to address nutritional considerations and ensure a balanced vegan diet that meets all necessary nutrient requirements. Proper meal planning, supplementation when needed, and awareness of potential deficiencies are vital for maintaining optimal health on a vegan diet.

While an omnivore diet can also support longevity, it is important to prioritize whole, unprocessed foods and consider the quality and quantity of animal products consumed. Making healthier choices within an omnivore diet and adopting a well-rounded lifestyle can positively impact lifespan.
