Veganism means abstaining from all animal products — meat, dairy, eggs, and honey included — and it has moved from niche philosophy to mainstream lifestyle over the past few decades. People choose it for animal welfare, health, or environmental reasons, often all three at once.
Here are some verified facts about veganism's history, science, and culture.
The word "vegan" was coined in 1944 by Donald Watson, a co-founder of the UK's Vegan Society, who combined the first three and last two letters of "vegetarian."
Plant-based eating for ethical and religious reasons dates back centuries, including vegetarian traditions among ancient Greek philosophers like Pythagoras and in Indian religious traditions such as Jainism, Hinduism, and Buddhism.
Research links well-planned vegan diets to lower rates of certain chronic conditions, including heart disease and type 2 diabetes, though results vary by study and depend heavily on diet quality.
A well-planned vegan diet can supply protein, iron, and calcium from plant sources like legumes, tofu, nuts, and leafy greens.
Vitamin B12 is the one nutrient vegans cannot reliably get from whole plant foods alone, since it's produced by bacteria and mainly found in animal products; fortified foods or supplements are recommended.
Vegan cuisine has expanded well beyond salads, with plant-based versions of burgers, pizza, ice cream, and chocolate now widely available.
Veganism often extends beyond food to cosmetics, clothing, and household products made without animal ingredients or animal testing.
Market research firms have projected rapid growth in the plant-based food industry over the past several years, with the global plant-based meat market valued in the low billions of dollars and forecast to roughly double by the mid-2020s.
Animal agriculture is a major contributor to greenhouse gas emissions; the UN Food and Agriculture Organization estimates livestock-related emissions at roughly 12-15% of global human-caused greenhouse gases.
Several well-known athletes and public figures have publicly embraced vegan or largely plant-based diets, including Formula 1 driver Lewis Hamilton and singer Ariana Grande.
A vegan diet doesn't have to be expensive — staples like grains, legumes, and vegetables are typically cheaper than meat, though packaged vegan substitutes can cost more.
Vitamin B12 deficiency is the most common nutritional risk for long-term vegans, which is why major dietetic associations recommend fortified foods or a B12 supplement.
Major health organizations, including the Academy of Nutrition and Dietetics, state that appropriately planned vegan diets can be healthy and nutritionally adequate at every stage of life, including for children, provided key nutrients are monitored.
Exploring vegan cooking often introduces people to a wider range of global cuisines, since many traditional dishes from South Asian, Middle Eastern, and East Asian cooking are naturally plant-based.
