Studies suggest that well-planned vegan diets can contribute to longevity, but the difference in lifespan between vegans and omnivores depends on multiple factors, including overall diet quality, lifestyle, genetics, and access to healthcare. Here’s a general comparison:
Lifespan Differences
Vegans: Some studies indicate that vegans may live 3 to 6 years longer than the average omnivore. This is often attributed to lower risks of heart disease, hypertension, type 2 diabetes, and certain cancers.
Omnivores: Those who follow a balanced omnivorous diet with a high intake of whole foods, lean proteins, and vegetables tend to have comparable lifespans to vegans. However, omnivores who consume high amounts of processed meats, refined sugars, and unhealthy fats may have shorter life expectancies due to increased risks of chronic diseases.
Key Health Considerations
Heart Disease: Vegans tend to have lower cholesterol and blood pressure levels, reducing heart disease risk.
Cancer: Some research suggests that vegans have a lower risk of certain cancers, likely due to higher intake of fiber and antioxidants.
Bone Health: Vegans may have a slightly higher risk of osteoporosis if they do not get enough calcium and vitamin D.
Protein Intake: Omnivores typically get sufficient complete proteins, while vegans need to be more mindful of protein variety.
Conclusion
A healthy vegan diet may slightly extend lifespan, but a well-balanced omnivorous diet with minimal processed foods can achieve similar longevity. Lifestyle factors like exercise, stress management, and sleep also play a significant role in overall lifespan.
