• ethics Abolitionism and veganism — Gary Francione's abolitionist approach treats veganism as the moral baseline and rejects animal welfare reform as a strategy for ending animal use.
• activism Activism — A half-century of animal-rights and vegan activism, from 1970s hunt saboteurs to modern cage-free pledges, corporate campaigns, ballot measures, and the evidence on what actually works.
• history Animal Liberation (1975) — Peter Singer's book, grown from a 1973 New York Review of Books essay, that brought utilitarian philosophy to bear on factory farming and laboratory experimentation and gave the modern animal movement its vocabulary.
• ethics Animal rights theory — From Regan's subject-of-a-life to Francione's abolitionism, Korsgaard's Kantian extension, Nussbaum's capabilities, and Donaldson and Kymlicka's Zoopolis — the deontological architecture of animal ethics.
• animals Animals — Who the animals at the center of the vegan worldview actually are — the species, the science of their minds, the scale of their use, and the relationships humans have with them.
• ethics Argument from marginal cases — The philosophical move that asks what cognitive trait could separate all humans from all animals — and what follows when no such trait survives scrutiny.
• health B12 and nerve damage — what's reversible and what isn't — B12 deficiency damages nerves through demyelination. Caught early, most damage reverses with treatment. Caught late, some damage becomes permanent — here's where the line is, and how to stay on the right side of it.
• nutrition B12 deficiency symptoms — What B12 deficiency actually feels like, in the order symptoms appear — from early fatigue and tingling to rare, irreversible neurological damage if untreated.
• nutrition B12 dosage for adults — The exact amounts of vitamin B12 healthy adult vegans should take — daily regimen vs. weekly regimen, why the numbers differ, and what to pick.
• nutrition B12 for vegan infants and children — How vegan parents should handle B12 for breastfed babies, formula-fed babies, toddlers, and older kids — with concrete dosing and red flags to watch for.
• nutrition B12 from fermented foods, spirulina, and nori — the analogue problem — Spirulina, chlorella, tempeh, nori, and most "natural plant B12" sources contain pseudovitamin B12 — inactive analogues that can't replace true B12 and may even block its uptake.
• nutrition B12 in pregnancy and breastfeeding for vegans — Vegan mothers need slightly more B12 during pregnancy and lactation, and getting it right protects the infant's developing nervous system. Here are the targets, risks, and a simple plan.
• nutrition B12 testing — what to ask your doctor — The four blood tests that evaluate B12 status, what their numbers mean, and how to ask for them without getting handed the wrong panel.
• animals Bees — cognition and use — What decades of cognitive research reveal about the minds of bees, how industrial beekeeping and commercial pollination shape their lives, and why honey sits outside vegan ethics.
• environment Biodiversity and animal agriculture — Animal agriculture is the single largest driver of terrestrial biodiversity loss, through habitat conversion, pollinator decline, and a livestock-dominated global mammal biomass that now dwarfs wild populations.
• science Cambridge Declaration on Consciousness — The 2012 statement by an international group of neuroscientists affirming that mammals, birds, and many other animals including octopuses possess the neural substrates of consciousness.
• health Cancer and plant-based diets — Plant-based diets are associated with modestly lower risk for several cancers — most consistently colorectal — through fibre, lower processed and red meat intake, lower IGF-1, and reduced heme iron and N-nitroso exposure.
• health Cardiovascular disease and plant-based diets — Plant-based diets are associated with lower cardiovascular disease risk through converging mechanisms — LDL reduction, blood pressure, and endothelial function — but diet quality matters as much as the label.
• science Cellular agriculture — Growing animal proteins and tissues without animals — cultivated meat, precision fermentation, and recombinant proteins, from Mark Post's 2013 burger to today's regulatory approvals and unresolved scale-up economics.
• animals Chickens — cognition and industry — The most numerous terrestrial vertebrate on Earth is a capable cognitive agent raised and killed inside the largest animal-production system humans have ever built.
• animals Cows, dairy, and beef — Who cows actually are — the cognition, the social life, the mother-calf bond — and the dairy and beef cycles that shape almost every cow alive today.
• culture Culture — The language, film, literature, music, religion, and regional traditions through which veganism becomes a way of life and a contested identity rather than a diet alone.
• nutrition Cyano vs methyl vs hydroxo — comparing B12 supplement forms — The four supplemental forms of vitamin B12 — cyanocobalamin, methylcobalamin, hydroxocobalamin, and adenosylcobalamin — explained honestly, with the right pick for healthy adults.
• environment Deforestation, the Amazon, and the beef-soy complex — Cattle ranching and soy-for-feed drive most Amazon and Cerrado forest loss, and policies like the Soy Moratorium and EU Deforestation Regulation are early attempts to break the link between diet and forest clearing.
• nutrition Does soy affect your hormones? — Meta-analyses of randomized controlled trials find no significant effect of typical soy intake on estradiol, testosterone, or thyroid hormones in healthy, iodine-replete adults.
• history Donald Watson — The Yorkshire woodworking teacher who coined the word "vegan" and co-founded the UK Vegan Society in November 1944.
• environment Environment — Food is the largest human pressure on Earth's systems, and the evidence converges on one conclusion — shifting away from animal products is the single highest-leverage environmental choice most people can make.
• ethics Ethics — The moral case for veganism — why sentience, not species, is what grounds the claim that animals count.
• animals Factory farming — Industrial animal agriculture — the system that raises most land animals eaten today, at enormous ethical, environmental, and public-health cost.
• animals Fish cognition and welfare — What the last two decades of research say about fish minds, fish pain, and the scale at which humans kill them — the largest and least-examined category of vertebrate use.
• health Gut microbiome and plant-based diets — How fibre-rich plant diets reshape gut bacteria, feed short-chain fatty acid producers, and lower TMAO — with honest caveats about responders and non-responders.
• health Health — What the peer-reviewed evidence actually shows about plant-based and vegan diets across cardiovascular disease, diabetes, cancer, longevity, weight, and the gut — plus an honest accounting of the nutrient risks.
• nutrition Heme vs non-heme iron: what the difference actually means — Heme iron absorbs faster but bypasses your body's safety valve; non-heme iron is self-regulating and — in plant-based eaters — absorbed more efficiently than population averages suggest.
• history History — From Pythagorean abstention and Jain ahimsa through the 1944 coinage of "vegan" to the global plant-based movement of the 21st century.
• nutrition How B12 absorption actually works — The body absorbs B12 through two pathways — one tightly capped, one passive and inefficient. Understanding this is the reason why vegan supplementing uses large, infrequent doses instead of tiny daily ones.
• science How to read a nutrition study — A field guide to reading diet research without being misled — study designs, confounding, FFQ noise, absolute versus relative risk, meta-analysis pitfalls, and conflict-of-interest checks.
• nutrition Iron absorption and vitamin C — Consuming 25–50 mg of vitamin C with every iron-rich plant meal can double or triple non-heme iron absorption — but only if the two are eaten at the same time.
• nutrition Iron and plant-based diets — Plant-based eaters typically consume more iron than omnivores yet have lower ferritin — and that gap reveals something important about how iron works, not a failure of the diet.
• nutrition Iron deficiency in vegan women — Menstruating vegetarian women — including vegans — face roughly 49% iron deficiency prevalence in the best available cohort study, nearly double omnivore rates, due to compounding menstrual losses and lower non-heme bioavailability. Here is what the evidence says and how to act on it.
• nutrition Iron needs in vegan children — Vegan children often meet iron intake targets but absorb less due to non-heme bioavailability — stores deplete before anemia appears, and one blood test and a few meal habits close most of the gap.
• nutrition Iron supplements for vegans — Ferrous bisglycinate, fumarate, or sulfate — the right form, dose, and timing makes the difference between effective repletion and GI-driven abandonment. Here is what the evidence says for plant-based eaters.
• nutrition Iron testing and ferritin explained — Ferritin is the best single iron test — but inflammation inflates it and hemoglobin misses early deficiency. Here is how to read a full iron panel and what the numbers mean for plant-based eaters.
• nutrition Iron-rich plant foods: a complete table — A ranked reference table of the best plant-based iron sources — legumes, seeds, soy foods, and grains — with per-serving values, bioavailability notes, and practical pairing tips.
• nutrition Is high-dose B12 safe? — Taking a 1,000 or 2,000 µg B12 supplement feels like a lot next to a 2.4 µg RDA. Here's why the math works out, what the evidence says about safety, and the specific situations where caution is warranted.
• nutrition Is nutritional yeast enough B12? — Nutritional yeast can cover vegan B12 needs — but only if it is explicitly fortified and you eat a meaningful amount of it every day. Here is how to tell, and why a dedicated supplement is still smarter.
• history Jainism and ahimsa — The oldest living lineage of principled non-harm, from Mahavira's five vows through graded respect for life to the contemporary Jain vegan turn on dairy ethics.
• environment Land use and animal agriculture — Animal products use roughly 77% of global farmland while supplying only 18% of calories and 37% of protein — making land the clearest single lens on the environmental cost of livestock.
• nutrition Legume preparation: soaking and sprouting — Soaking and sprouting legumes substantially reduces phytate, improving iron, zinc, and protein bioaccessibility — here is what the evidence says and how to do it.
• science Life-cycle assessment of food — How life-cycle assessment (LCA) quantifies the environmental impact of foods — what it measures, how boundary and allocation choices shape results, and where the method's blind spots lie.
• environment Livestock and climate — Animal agriculture is responsible for roughly 14–20% of global greenhouse-gas emissions and is the dominant human use of land.
• health Longevity and plant-based diets — What large cohorts, Blue Zones work, and mechanistic studies actually say about plant-based eating and how long — and how well — people live.
• environment Oceans, overfishing, and bycatch — Industrial fishing has depleted a third of assessed marine stocks, scraped seabeds at continental scale, and turned aquaculture into an extension of wild-catch pressure — with bycatch, ghost gear, and dead zones compounding the damage.
• nutrition Phytates and iron absorption — Phytate inhibits non-heme iron absorption dose-dependently, but soaking, sprouting, and fermentation reduce it by up to 85% — and phytate also carries antioxidant and anti-cancer properties worth preserving.
• animals Pigs — cognition and industry — What science says about the minds of pigs, and the industrial systems — gestation crates, tail docking, farrowing stalls, slaughter — that shape the lives of roughly 1.4 billion of them each year.
• nutrition Plant protein digestibility and DIAAS — DIAAS replaces PDCAAS as the gold-standard protein quality score: soy rates as high quality (91), while wheat (48), rice (47), and hemp (~54) fall below the threshold — and processing can shift any of these numbers significantly.
• health Plant-based diet — A dietary pattern built around whole plant foods — the practical foundation of vegan eating, with robust evidence for health and longevity.
• science Precision fermentation — Engineered microbes producing animal proteins — whey, casein, ovalbumin, collagen, heme — via the same recombinant-DNA platform that has made insulin and chymosin for forty years, now extended to dairy and egg.
• products Products — The vegan product landscape spans food, fashion, cosmetics, household, and pet categories — anchored by certification marks and a market scaling from niche to mainstream through both reformulation and frontier biotechnology.
• nutrition Protein — How much protein you actually need on a plant-based diet, why "incomplete protein" is a myth, and the simplest way to meet your target every day.
• nutrition Protein for vegan athletes — Plant-based athletes match omnivores for strength and may have an aerobic edge — the key is hitting 1.6–2.0 g/kg daily from quality sources like soy, pea-rice blends, and strategic supplementation.
• nutrition Protein for vegan seniors — Seniors need 1.0–1.2 g of protein per kilogram of body weight daily — 50% more than the standard RDA — and vegan seniors can meet this target with deliberate meal planning across three high-protein plant-food meals.
• nutrition Protein powders for vegans — Soy and pea-rice blends match whey for muscle outcomes when leucine is adequate — but most vegans don't need powder, organic varieties aren't safer, and hemp is the weakest option by protein quality.
• history Pythagoras and the Pythagorean diet — How the sixth-century BCE philosopher of Samos became the West's longest-standing byword for meat abstention, and why his ethics survived into modernity.
• recipes Recipes — Vegan cooking as a craft — the techniques, world cuisines, and kitchen fundamentals that make plant-based food genuinely delicious.
• science Science — The empirical ground under veganism — how nutrition, agronomy, animal cognition, food systems modelling, and cellular agriculture are actually measured, and how to read the evidence without overreaching it.
• ethics Sentience — The capacity for subjective experience — what science is learning to detect, and why it is the hinge of animal ethics.
• ethics Speciesism — Discrimination based on species membership — the moral error that veganism names and refuses.
• nutrition The complete protein myth — Plant foods contain all nine essential amino acids; the rule that vegans must combine proteins at every meal was popularized in 1971 and retracted by its own author a decade later.
• animals The dairy industry — How modern dairy actually works — the biology, the byproducts, the welfare reality, the environmental footprint, and the health evidence that makes milk a more complicated food than its marketing suggests.
• history The founding of the Vegan Society (1944) — How Donald Watson, Elsie Shrigley, and a handful of non-dairy vegetarians broke from the Vegetarian Society in November 1944, coined the word "vegan," and built the institutional apparatus that still carries the movement.
• nutrition Tofu vs tempeh vs seitan — All three are high-protein vegan staples, but they differ sharply in amino acid quality, digestibility, and who can safely eat them — tofu and tempeh win on protein quality; seitan wins on density but loses on completeness.
• health Type 2 diabetes and plant-based diets — Plant-based dietary patterns are associated with substantially lower incidence of type 2 diabetes and can improve glycemic control in people who already have it.
• ethics Utilitarianism and animals — From Bentham's 1789 footnote to Singer's equal consideration of interests and today's Rethink Priorities moral-weight work — the utilitarian case for taking animal suffering seriously.
• health Vegan pregnancy — A well-planned vegan diet can support a healthy pregnancy and a healthy baby, provided a small set of nutrients — B12, iodine, DHA, iron, choline, vitamin D, calcium, zinc, and folate — are deliberately covered.
• ethics Veganism — A philosophy and way of living that seeks to exclude, as far as possible and practicable, all forms of exploitation of, and cruelty to, animals.
• history Veganuary — The UK-born pledge campaign that since 2014 has invited participants to try veganism for the month of January, reshaping retail ranges and public discourse about plant-based eating.
• nutrition Vitamin B12 — The one nutrient every vegan must supplement — produced only by bacteria, essential for nerves and blood, and trivial to get right once you know how.
• environment Water footprint of animal agriculture — Animal products dominate agricultural water use, with beef requiring around 15,000 litres per kilogram and regional scarcity hotspots driven heavily by feed and forage crops.
