The Impact of Veganism on Mental Well-Being: A Global Perspective

Veganism is more than just a dietary choice; it’s a lifestyle that is rapidly gaining traction worldwide. As of 2024, approximately 3% of the population in the USA identifies as vegan, while in the UK, this figure has surged to 7%. In India, reports suggest that around 30% of urban youth are adopting vegan diets, reflecting a significant cultural shift. This blog delves into the intricate relationship between veganism and mental well-being.

The Numbers Behind Veganism

Global Vegan Population

As per the analysis by Expert Market Research, the global vegan food market size reached a value of about USD 27.07 billion in 2024. The market is projected to grow at a CAGR of 10.1% in the forecast period of 2025-2034 to reach a value of approximately USD 64.36 billion by 2034.

As of 2024, the global vegan population is estimated to be around 79 million, which represents just over 1% of the world's total population of approximately 7.8 billion people. This figure reflects a significant increase in veganism's popularity, particularly in regions such as the UK, where about 4.7% of adults identify as vegan, translating to approximately 2.5 million individuals. In the USA, around 3% of the population is vegan, equating to about 10 million people. Other countries also show notable trends; for instance, 9% of urban youth in India are adopting vegan diets, while Israel boasts a vegan population of around 5%. 

In Europe, countries like Germany and Austria are experiencing a rise in veganism, with estimates suggesting that approximately 2.2% of their populations follow a vegan diet. Moreover, surveys indicate that many individuals have now transitioned from vegetarianism to veganism, with 52.1% of vegans having been vegetarians prior to their current dietary choices. The driving forces behind this shift often include concerns for animal welfare (68.1%), health reasons (17.4%), and environmental sustainability (9.7%). These numbers indicate a growing trend toward plant-based diets, driven by health consciousness and ethical considerations.

Positive Effects of Veganism

Research indicates that dietary choices can significantly impact mental health. A study highlighted by Earth911 found that participants following a low-fat vegan diet reported reduced levels of depression and anxiety after 18 weeks. Another research published in the British Journal of Psychiatry found that individuals consuming more whole foods reported fewer symptoms of depression than those who primarily ate processed foods. This suggests that a well-planned vegan diet can enhance mood and overall mental well-being. Here are additional statistics:
