While more research is still needed, current evidence indicates veganism done thoughtfully can be an empowering path to improving mental health. This article equips readers with information to make informed decisions about pursuing a mentally-flourishing plant-based lifestyle.

What is Veganism?

Veganism is a lifestyle and philosophical movement that seeks to avoid the use of animals for food, clothing, or any other purpose. The key principle of veganism is avoiding all forms of animal exploitation and cruelty as far as possible and practicable.

Vegans do not consume meat, fish, dairy, eggs, or honey. However, veganism extends beyond just diet – vegans also avoid leather, wool, silk, and other animal-derived products. There are several forms of veganism, including:

  • Dietary vegans – focus on food choices
  • Environmental vegans – motivated by sustainability
  • Ethical vegans – guided by animal rights philosophy
  • Raw food vegans – eat uncooked plant foods

The reasons for following a vegan lifestyle vary, but all vegans share the goal of avoiding harm to animals through their diet and consumer choices.

The Rise of Veganism

Veganism has seen a meteoric rise in popularity over the past decade. According to a report by GlobalData, there was a 600% increase in people identifying as vegans in the United States between 2014-2017. The UK saw a 350% rise in veganism between 2006-2016.

Several factors are driving more people to go vegan:

  • Increased awareness of industrial animal farming practices and desire to avoid supporting perceived cruelty to animals. Films like Dominion and Cowspiracy have exposed the realities inside factory farms and slaughterhouses.
  • Environmental concerns, especially around animal agriculture’s contributions to climate change, water pollution, and deforestation. Many view adopting a plant-based diet as an eco-friendly choice.
  • Improved availability and quality of vegan options, making the lifestyle more accessible. Mainstream brands like Ben & Jerry’s now offer dairy-free ice cream.
  • Celebrities and influencers promoting the perceived health and ethical benefits of vegan living. Stars like Natalie Portman and Venus Williams have publicly embraced plant-based diets.
  • Social media communities help vegans connect and share advice for transitioning successfully.

Overall, veganism is now firmly in the mainstream, attracting followers of all ages and demographics.

Veganism and Mental Health

Several studies indicate vegan diets may benefit mental health and well-being in various ways:

Lower levels of stress and anxiety

  • A 2020 systematic review found vegetarians and vegans had a 34% lower risk of anxiety disorders compared to meat eaters.
  • Possible reasons include reduced inflammation, antioxidants protecting brain cells from damage, and the mood-lifting properties of nutrients like vitamin C.

Decreased depression

  • Data from Adventist Health Study 2 linked vegetarian diets with a less depressed mood state. This large cohort study followed over 97,000 participants for 2.5 years.
  • Plant foods contain compounds like polyphenols that can help regulate neurotransmitters linked to depression, like serotonin.

Enhanced mood

  • A 2015 Spanish study found vegans had lower levels of stress, anxiety, and depression, with elevated positive mood states compared to meat eaters. However, the vegan group was small (n=21) warranting further research.

Cognitive benefits

  • A higher intake of fruits, vegetables, and nuts is associated with slower age-related cognitive decline. This may be due to increased blood flow and oxygen supply to the brain.

However, some dispute claims that veganism inherently improves mental health, arguing benefits are not guaranteed:

  • There are confounding factors as health-conscious individuals more often pursue veganism. Improvements may be unrelated to diet.
  • Some associate mood problems with nutrient deficiencies. However, balanced vegan diets can provide optimal nutrition.
  • Highly restrictive diets could negatively impact those prone to orthorexia or eating disorders. Careful monitoring of mental health is required.

Overall, most studies controlled for factors like BMI and physical activity, strengthening the case that plant-based diets are advantageous for mood and cognition. But individuals can respond differently based on planning, life circumstances, and pre-existing conditions.

Nutrition and Brain Health

A vegan diet planned appropriately can provide nutrients vital for optimal brain health and mental well-being. Here are some key considerations:

Vitamin B12

  • Essential for neurological function, cell metabolism, and red blood cell formation.
  • Found mostly in animal foods so vegans must supplement B12 or consume fortified foods.
  • Deficiency is linked to psychiatric disorders like depression and dementia.

Omega-3 fatty acids

  • Mainly ALA from plant foods and DHA/EPA from seafood and algae.
  • Important for neuronal membrane structure and anti-inflammatory effects.
  • Vegan sources include chia, flax, walnuts, and algae oil. DHA supplements may be prudent for some.


  • Low iron is associated with anxiety, brain fog, and restless legs syndrome.
  • Beans, lentils, spinach, and fortified cereals can provide iron for vegans. Vitamin C aids absorption.


  • Crucial mineral for neuron transmission and synaptic plasticity.
  • Nuts, seeds, legumes, oats, and wheat germ can meet vegan zinc needs.


  • Found abundantly in fruits, vegetables, and spices. Protect brain cells from oxidative damage.
  • Linked to reduced risk of neurodegenerative diseases like Alzheimer’s.

Overall, well-planned vegan diets low in processed foods can provide great brain nutrition. But without guidance, restrictive diets raise the risk of deficiencies, hence the importance of monitoring the intake of key nutrients like B12 and omega-3s. Consulting a dietitian may be advisable for some.

Ethics, Mindfulness, and Mental Health

Some evidence suggests the ethical foundations and mindful approach of veganism itself can benefit mental well-being:

  • Making compassionate food choices aligned with one’s values is linked to higher self-esteem and life satisfaction. This may be from reduced cognitive dissonance.
  • Being part of a social justice movement provides meaning and purpose for some vegans. Activism and volunteering can enhance mood and social connections.
  • Mindfulness practices around preparing plant-based meals and appreciating the flavors and textures of vegan food may have a calming, therapeutic effect.
  • Avoiding harsh images and realities inside factory farms could alleviate empathic distress that negatively impacts mental health.

However, these mental health boons are not inevitable or exclusive to veganism. Some critique the purported benefits as exaggerations:

  • Omnivores are equally capable of living according to their ethics through humane meat sourcing and activism.
  • Cooking and savoring meat-inclusive meals also fosters mindfulness.
  • Not all vegans are motivated by animal ethics – environmental and health reasons are more salient for some.
  • Mental health gains depend on individual disposition – simply avoiding animal products does not guarantee moral satisfaction.

More research is required to substantiate the impact vegan philosophy has on mental well-being and understand how effects may differ based on person and context. While anecdotal accounts of enhanced meaning, purpose, and tranquility abound in the vegan community, empirical data remains limited.

    Addressing Criticisms and Concerns

    Here are some responses to common criticisms regarding veganism and mental health:

    • Claims that mental health benefits are exaggerated can be countered by citing research controlling for confounders like BMI and exercise. However, individual factors still influence outcomes.
    • Fears about nutrient deficiencies and mental health impacts are valid but can be addressed through proper planning and supplementation where required. Vegans should monitor their intake of nutrients like B12, omega-3s, iron, and zinc.
    • Arguments that highly restrictive diets trigger disorders like orthorexia are reasonable concerns. Vegans with a history of eating disorders or obsessive tendencies require support and guidance to maintain a balanced approach.
    • The contention that animal ethics and mindfulness components are overhyped may have some merit. Not all vegans are motivated in this way. However, anecdotal reports from many individuals suggest meaningful mental health gains in these domains.

    Overall, while vegan diets can benefit mental well-being through multiple mechanisms, risks around malnutrition and orthorexia must be acknowledged and mitigated through mindful, moderate plant-based eating. Further research is warranted, especially regarding the understudied psychosocial and philosophical impacts of pursuing veganism.

      Tips for a Mentally Healthy Vegan Lifestyle

      Here are some tips for optimizing mental health and well-being while following a vegan diet:

      • Plan balanced nutrient-dense meals. Include sources of protein, omega-3s, iron, zinc, and vitamin B12. Consider supplements if needed.
      • Gradually transition to veganism over weeks/months to allow time for body and mind to adjust. Make lasting changes at a sustainable pace.
      • Find social support like vegan groups or online communities. This provides accountability, advice, and a sense of belonging.
      • Set realistic expectations for your vegan journey. Be compassionate with yourself if challenges arise.
      • Explore new plant-based cuisines, recipes, and restaurants. Keep things fun and interesting.
      • Make self-care a priority through rest, exercise, nature time, and relaxing activities unrelated to diet.
      • Seek professional help if struggling with disordered eating, anxiety, or depression. Veganism should enhance, not harm, mental health.
      • Remember veganism is just one part of your identity and life. Pursue work-life balance and don’t become obsessed.

      With thoughtful planning and self-awareness, almost anyone can succeed and thrive on a vegan diet while promoting mental wellness.
