No ammo.

A well-planned vegan diet can be healthy, says the British Dietetic Association, and a 2023 review found 21% less ischaemic heart disease in vegetarians. Vegans had more hip fractures in EPIC-Oxford, and death rates are mixed.

You don’t need meat to be healthy, say dietitians in five countries, if your diet is planned and includes B12. UK vegetarians died at about the same rate as meat-eaters (2016), though they and vegans break more hips.

A 2026 review found just nine studies of the carnivore diet, most of them small, and LDL cholesterol rose in several. Plant-based diets have been studied in hundreds of thousands of people, though vegans need B12.

Going vegan needn’t make you tired or weak if you eat enough and get B12, but plan for iron: across four studies, a 2021 review found 15% of vegans and 7% of meat-eaters iron deficient. See a GP if tiredness lasts weeks.

Needing B12 doesn’t single out a vegan diet as unnatural: the US Institute of Medicine advised in 1998 that everyone over 50 get most of their B12 from supplements or fortified food. Vegans need such a source at every age.

Vegan junk food is still junk food: in a 2017 study of over 200,000 US health workers, diets richest in whole plant foods had 25% less coronary heart disease than the poorest, and those richest in refined ones 32% more.

Processed meat raises bowel cancer risk by 18% per 50 g a day, the WHO’s cancer agency found in 2015, and red meat probably does too. Both are linked to diabetes, poultry less firmly, and each person’s risk is small.

Chicken looks healthier than red meat in most long-term studies, which tie red meat but not poultry to heart disease. But in a 2019 trial with saturated fat matched, LDL cholesterol was as high on white meat as on red.

Grass-fed beef has more long-chain omega-3 than grain-fed beef, 65 mg per 100 g against 48 mg in an Australian study (Ponnampalam et al., 2006), but no study has shown it lowers disease risk. It is still red meat.

Most people can eat eggs as part of a healthy diet, though a 2022 analysis of cohorts with 3.6 million people linked each extra egg a day to 4% more cardiovascular disease. The link looks stronger with diabetes.

Adults don’t need dairy, and its record is mixed. Meta-analyses for the World Cancer Research Fund tied each 400 g a day to 13% less bowel cancer (2017) and 7% more prostate cancer (2015), the second on weaker evidence.

Seed oils don’t look bad for the heart. People with the most of their omega-6 fat in blood or body fat had 22% less cardiovascular death across 17 cohorts (2019), and trials cutting saturated fat cut heart events by 17%.

A vegan diet can meet protein needs when meals are built on pulses or soya: the UK reference, set in 1991, is 0.75 g per kilo a day, about 53 g at 70 kg. Older people, athletes and pregnant women should plan for more.

Athletes can be vegan: a 2025 meta-analysis of randomised trials found no significant strength gap between plant and animal protein, but less muscle with plant, more so with weight training. Plan protein, B12 and iron.

Vegans who eat enough protein build muscle much as meat-eaters do: in a 2021 trial, vegan and omnivorous novices on 1.6 g of protein per kilo a day gained the same leg muscle. Soy matches milk protein; others lag a little.

Vegans don’t need to combine proteins at every meal: in a 2024 US trial of nine women, 24-hour muscle protein synthesis did not differ whether beans and bread were eaten together or apart. Total protein is what to watch.

Vegan men had no less testosterone than meat-eaters in UK Biobank (Tong et al., 2021): 166 white British vegans averaged 11.7 nmol/l and regular meat-eaters 11.3, not a significant gap. Meat’s appeal to men looks partly cultural.

Vegans need B12 from fortified foods or a supplement: the Vegan Society advises at least 10 micrograms a day or 2,000 a week, as UK dietitians repeated in 2021. It matters most in pregnancy and while breastfeeding.

Calcium needn’t come from dairy, but vegans in EPIC-Oxford (2020) had a 43% higher fracture rate than meat-eaters, only partly explained by low calcium. Get at least 700 mg daily from fortified foods and calcium-set tofu.

Vegans can meet the choline target with soya, beans or a supplement, but it takes planning: Storz et al. (2025) found German vegans ate 257 mg a day and meat-eaters 329 mg, against EFSA’s 400 mg. Needs rise in pregnancy.

Vegans tend to eat at least as much iron as meat-eaters but store less: a 2021 review found ferritin averaged 31.3 µg/L in vegans, 55.5 in meat-eaters. Anaemia is also more common, especially in premenopausal women.

Vegans need omega-3 like anyone, and can get EPA and DHA from algae oil, where fish get theirs: a 2025 analysis of a randomised trial found it raised blood levels as well as fish oil, dose for dose.

Vegans average lower vitamin D than meat-eaters, and UK advice since 2016 asks everyone to consider 10 micrograms a day in autumn and winter. Take it as D2 or lichen D3, and all year if you have dark skin or get little sun.

Iodine is a weak spot for vegans: a 2023 review (Eveleigh et al.) found them lowest in all five studies measuring urinary iodine. UK dietitians suggest adults use iodine-fortified plant milk or a supplement of up to 150 µg daily.

Vegans have lower bone density on average and, in EPIC-Oxford (2020), 2.3 times meat-eaters’ hip fracture risk, about 15 more per 1,000 people over ten years. Lower weight, calcium and protein explain only part of it.

Zinc and selenium need planning on a vegan diet: two German studies (2023, 2025) found 7% to 40% of vegans with low blood selenium, against at most 2.5% of meat-eaters. A low-dose supplement is steadier than Brazil nuts.

Dietitians say a well-planned vegan diet can suit children, but a 2026 meta-analysis of 59 studies found vegan children shorter on average and more often short of B12. Paediatricians urge B12 supplements and monitoring.

Canadian, Irish and UK dietitians say a planned vegan diet can suit pregnancy and breastfeeding. Babies from vegan homes were about 100 g lighter at birth but grew much like others by two (Israel, 2026). Take B12.

A vegan diet can suit older people if planned: in a 2026 Dutch trial, over-65s who chose their own vegan food ate less protein and lost thigh muscle in 12 weeks. Vegans have more hip fractures, so bones need care too.

A vegetarian diet with lifestyle changes partly reversed heart disease in small studies: in Ornish’s 1998 trial, artery narrowing eased 3.1 points in five years, against 11.8 worse on usual care. Try it alongside your medicine.

A vegan or vegetarian diet cut LDL cholesterol by about 10% in a 2023 European Heart Journal meta-analysis of 30 trials, less than a statin. The two can be combined, and nobody should stop a statin without their doctor.

A plant-based diet is linked to a lower risk of type 2 diabetes, 18% lower in a 2023 meta-analysis of observational studies, and in trials it modestly lowers blood sugar. On diabetes medicine? See your GP first.

Processed meat causes bowel cancer and red meat probably does, the WHO’s cancer agency found in 2015. In UK data, 79 g a day of both meant 14 more bowel cancers per 10,000 people over about seven years than under 11 g.

A plant-based diet feeds the gut bacteria that ferment fibre, and UK adults average just 16.4 g of fibre a day against the 30 g advised (2025 survey). In one 2025 study, vegans’ gut bacteria were slightly less diverse.

Soy foods have not been found to raise breast cancer risk: in 300,852 women, the China Kadoorie Biobank (2020) saw no difference between the highest and lowest soy eaters. In survivors soy is linked to fewer recurrences.

No study shows that a vegan diet causes depression. Most meta-analyses find more depression in people who avoid meat, but Tan et al. (2026), tracking 77,678 people, found the link small and unlikely to be causal.

Soy did not significantly change men’s testosterone or oestrogen in a 2021 meta-analysis of 41 clinical studies (Reed et al.). A few case reports tie heavy soy intake to breast growth or low testosterone.

Vegans can eat low-carb: in Eco-Atkins (2014), a lower-carb vegan diet cut LDL 0.49 mmol/L more than a high-carb vegetarian one, though half its group quit. Vegan keto is untested; on diabetes drugs, see a doctor first.

Lectins in properly cooked beans have no proven harm: cooking cut lectin activity in pulses by 94 to 99.8% in a 2018 Canadian study. Undercooked kidney beans can poison you, and phytate cuts iron and zinc absorption.

No evidence shows that eating for your blood type improves health: a 2013 systematic review screened 1,415 references and found no such study. Later studies found that matching a diet to blood group made no difference.

Vegans don’t need collagen or animal fat, as the body builds collagen from amino acids with vitamin C and iron. In EPIC-Oxford (2016), vegan men had 16% more glycine but 13% less lysine in their blood than meat-eaters.

A strict raw diet, vegan or not, carries real risks: in Germany’s Giessen Raw Food Study (1999), about 30% of women under 45 eating mostly raw had partly or fully lost their periods. Cooking makes many plant foods safer.

Gluten harms the roughly 1% with coeliac disease (0.8% by biopsy in a 2026 global review), and wheat can make those with a wheat allergy or sensitivity ill. For others, wholegrains are linked to better health.

Eating meat isn’t a purely personal choice, because animals die for it: a 2021 estimate by the charity research group Animal Charity Evaluators puts the worldwide average at about 105 vertebrates a year per non-vegan, mostly fish.

Nothing about pigs justifies eating them while protecting dogs: pigs feel pain and fear too, as the UK government’s Animal Welfare Committee found in 2025. Which animals count as food is largely cultural habit.

Far fewer farm animals would exist if we stopped eating them, but having bred an animal is a poor reason to kill it, and in the EU a typical fast-growing meat chicken is slaughtered at about 37 days old (EFSA, 2023).

Valuing humans over animals is speciesist when species alone is the reason, the bias Richard Ryder named in 1970. Real differences in ability can matter, but none of them separates every human from every animal.

An animal’s inability to consent doesn’t license harming it: newborns can’t consent either, and the UN Convention on the Rights of the Child (1989) makes a child’s best interests a primary consideration.

Animals needn’t understand death to suffer as they die: 90% of pigs in England and Wales are stunned with CO2 (UK government, 2024), a gas UK advisers say causes pain and fear. A painless death still cuts a life short.

A lion’s diet can’t license ours: lions are obligate carnivores that can’t choose otherwise, while the British Dietetic Association says carefully planned plant-based diets can support healthy living at every age.

Canine teeth are poor evidence we’re built for meat: in apes and monkeys their size mainly tracks male rivalry, and in our lineage male canines had shrunk to near-female size by about 4.5 million years ago (Suwa et al., 2021).

Eating meat is ancient and natural for an omnivore, but neither makes it right, and today’s amount is recent: FAO figures show meat available per person worldwide nearly doubled between 1961 and 2023.

Humans evolved as omnivores and can eat meat, but the US Academy of Nutrition and Dietetics (2025) says a planned vegan diet can be nutritionally adequate for adults. Vegans need B12 from fortified foods or supplements.

Animal farming is not the circle of life: most farmed land animals are chickens, and in the EU a meat chicken is usually killed at about 37 days old, well before it can breed (EFSA, 2023).

Plants almost certainly can’t feel pain, having no neurons or brain, and if they could, eating meat would cause more of it: US livestock return only about 7% of their feed calories as food (Shepon et al., 2016).

Crop deaths are real, but eating meat almost always causes more of them, because farm animals eat crops too: Poore and Nemecek (2018) found a world without animal products would need 19% less arable land.

Vegans draw the line at sentience, and a 2021 review of over 300 studies for the UK government found strong evidence that even crabs and octopuses can feel pain. Doubt about insects leaves cows and pigs inside the line.

Swatting a biting mosquito isn’t vegan hypocrisy, as the Vegan Society’s definition stops at what is practicable. Adult flies and mosquitoes met 6 of 8 pain criteria in a 2022 review, so gentler options come first.

Roadkill and binned meat aren’t vegan food, since the Vegan Society’s definition excludes all animal products from the diet, but eating them pays nobody to breed or kill an animal, the harm veganism exists to prevent.

Vegans aren’t hypocrites for falling short of 100% vegan: the Vegan Society defines veganism as excluding animal exploitation ‘as far as is possible and practicable’, and what goes on the plate is chosen at every meal.

Oysters and mussels aren’t vegan by the Vegan Society’s definition, which excludes shellfish. Whether they feel pain is unresolved: a preliminary 2022 literature scan by Wageningen Marine Research found no direct test.

Indigenous and subsistence diets don’t disprove veganism, which the Vegan Society defines as avoiding animal exploitation only “as far as is possible and practicable”. A hunter’s necessity doesn’t cover supermarket meat.

The Bible allows people to eat meat, but the chapter of Genesis that gives humans dominion gives them only plants to eat (1:29), and the Catholic Catechism calls needless animal suffering contrary to human dignity.

Few religious rules require eating meat: Islam’s main sacrifice, qurbani, falls at one festival a year, and in a Pew Research Center survey of India (2021), 44% of Hindus said they were vegetarian.

One person going vegan does make a difference: the charity research group Animal Charity Evaluators estimated in 2021 that a plant-based person accounts for about 105 fewer vertebrates killed a year.

If everyone went vegan, farm animals would not be set loose: farmers would breed fewer as demand fell, and the land animals slaughtered for meat, at least 86 billion in 2024 on FAO figures, would dwindle.

Animal farming is no small problem: more than 86 billion land animals were slaughtered for meat in 2024, on UN Food and Agriculture Organization figures. Eating differently needn’t take time or money from other causes.

Farm breeds would dwindle in a vegan world and some could be lost, but eating meat on today’s scale hasn’t stopped them dying out: the UN’s FAO found 63% of local breeds with a known status at risk of extinction in 2025.

Most chickens raised for meat are not kept humanely: they are bred to grow so fast that many go lame, and in 2023 the EU’s food safety agency advised at most 11kg of bird per square metre, where EU law allows up to 42kg.

Egg production kills hens and their brothers: about 6.5 billion male chicks of laying breeds die each year worldwide, by a 2026 estimate RSPCA Australia cites, and hens are slaughtered once laying slows.

Chickens are far from stupid: Lori Marino’s 2017 review found them as cognitively, emotionally and socially complex as most other birds and mammals in many areas. Their number sense is basic, and mostly tested in chicks.

Backyard eggs still have costs: hens sold as females were sorted from their brothers, and the egg trade kills about 6.5 billion male chicks a year, by a 2026 estimate RSPCA Australia cites. Heavy laying also weakens hens’ bones.

Milk costs the cow her life in the end: dairy cows were 56% of the cows slaughtered in Britain from 2021 to 2025 (AHDB industry figures). In 195 UK herds in 2023, the typical cow left the herd at about six.

Most veal comes from male dairy calves, born because cows must calve to give milk, then reared for meat, exported or shot young. Ireland exported 203,000 unweaned calves in the first nine months of 2026, its government said.

Most farm animals live nothing like those in adverts: the Sentience Institute, an animal-advocacy think tank, put 74% of livestock in factory farms in a rough 2019 estimate. Dairy cows typically leave the herd at four to six.

Wool isn’t vegan, and leather is a by-product that is still sold: in October 2026 a US steer’s hide fetched about $24, under 1% of its price, and all its by-products about 7%, paid to the business that killed it (USDA).

A lamb’s life in the fields is real but short: in the UK, the RSPCA says most lambs are slaughtered between 10 weeks and six months old, while Countryfile (2026) puts a sheep’s natural lifespan at 10 to 12 years.

Wool is more than a haircut for Australian Merinos: the industry’s Australian Wool Exchange found 60.7% of Merino wool bales in 2025/26 came from mulesed sheep, which had skin cut from their rear as lambs.

Fur, silk and down all come from animals that are killed: the welfare charity RSPCA Australia (2019) estimates about 98% of down and feathers is collected after slaughter, and conventional silk pupae are killed by heat.

Fish very likely feel pain: in studies Lynne Sneddon reviewed in 2015, trout given a painful lip injection went up to 3 hours without food, but ate after 80 minutes if also given a painkiller. Some scientists dispute it.

Fish are killed in the trillions: a 2024 study in the journal Animal Welfare put the wild catch at an average of 1.1 to 2.2 trillion fish a year from 2000 to 2019. Most fish, wild or farmed, die without being stunned.

Foie gras is cruel by design: the EU’s scientific committee on animal welfare (1998) found force-feeding swells a duck’s or goose’s liver to six to ten times its normal size and harms the birds’ welfare.

Honey isn’t vegan because bees make it as their winter food and beekeepers take it, feeding syrup where stores run short. A 2018 paper in Science warned that high densities of managed honeybees can harm wild pollinators.

Many insects can probably feel pain: in a 2022 review by Gibbons et al., adult flies and cockroaches met 6 of 8 pain criteria, more than the crabs and lobsters UK law treats as sentient. Farmed larvae are less studied.

Free-range and humane farming can ease an animal’s life but still end it young: under a 2008 EU regulation still in force in Great Britain, a free-range chicken can be killed at 56 days old.

So-called humane slaughter still hurts: 90% of pigs in England and Wales were gassed with CO₂ in 2024 (FSA), a method that welfare advisers to the UK government and the EU say causes pain, fear and breathlessness.

Slaughter without stunning, for kosher and some halal meat, is no kinder: UK advisers judged the cut very painful (FAWC, 2003), and most cattle stay conscious 5 to 90 seconds (EFSA, 2020). Stunning has its own cruelties.

Cosmetic animal testing is only partly banned: the campaign group Humane Society International counted 45 countries with bans in 2023, and the US has no national ban. EU chemicals law can still demand such tests.

Animal testing is still standard for new medicines, though Ineichen and colleagues (2024) found only 5% of animal-tested therapies won approval. US law stopped requiring it in 2022, and the FDA plans to phase it out.

About 192 million animals were used or bred for science worldwide in 2015, 79.9 million of them in procedures, Cruelty Free International researchers estimated in 2019. Only 37 countries published counts.

Zoos and aquariums have helped save a few species, but most of what they keep is not endangered: Lennon et al. (2026) found under three in ten animals in UK zoos and aquariums belonged to threatened species.

Racing, competitive riding and circuses use animals for a spectacle they never chose, and the cost is measurable: British racing’s own figures record 192 horses fatally injured in 2025.

Going vegan cuts a diet’s climate cost sharply: a 2023 Oxford study of 55,504 people in the UK found vegan diets produced about a quarter of the emissions of diets with 100g or more of meat a day.

Grass-fed and regenerative beef is not carbon-negative at scale: an Oxford-led review (2017) found better grazing could offset at most 20 to 60% of grazing livestock’s emissions, and only for a few decades.

Cow methane is a serious climate problem: a tonne traps 27 times as much heat as CO2 over a century (IPCC, 2021). The figure overstates a steady herd’s warming and understates a growing one’s, and cuts pay off fast.

What we eat matters for the climate alongside fossil fuels: the IPCC (2022) put food systems at 31% of global greenhouse gas emissions in 2018, and Clark et al. (2020) found food on current trends would breach 1.5°C.

Cow methane is recycled carbon, but that only slightly lowers its warming: the IPCC (2021) rates a tonne at 27 times CO2 over a century, and fossil methane at about 30. A steady herd keeps up the warming it has caused.

Soy farming does clear forest, but cattle clear far more: Singh and Persson (2026) linked 42% of deforestation from 2001 to 2022 to pasture and 16% to all oil crops, soy included. Most soy feeds livestock.

A mainly plant-based diet could feed the world: Berners-Lee and colleagues (2018) found today’s crops could feed 9.7 billion people in 2050 if most meat and dairy gave way to plants and food reached far more people.

Farming can work without animals: manure only returns nutrients from feed, and animal products use 83% of farmland for 18% of calories (Poore and Nemecek, 2018). Stockfree soils need legumes to hold their organic matter.

Palm oil is vegan and has cleared real forest, but cattle pasture has cleared far more: the World Resources Institute (2021) found pasture replaced 45.1 million hectares of tree cover from 2001 to 2015, oil palm 10.5 million.

Animal farming is one of the biggest drivers of biodiversity loss: changing how land and sea are used is the top cause (IPBES, 2019), and meat, dairy, eggs and farmed fish take up 83% of farmland (Poore and Nemecek, 2018).

If everyone went vegan, the world would need about three-quarters less farmland: Poore and Nemecek (2018) found food’s land use would fall by 3.1 billion hectares, mostly pasture that could return to natural vegetation.

Animal farming uses a lot of water even with rain left out: in a 2023 Oxford study of 55,504 UK adults, vegans’ diets used 46% of the water of high meat-eaters’. Nuts and rice are thirsty too, and modelled diets vary.

Seafood is often unsustainable: the FAO found 37.6% of assessed marine fish stocks overfished in 2023. Most landed fish came from stocks it rated sustainable, a test that ignores harm to seabirds, turtles and the seabed.

It depends how you count: per litre, almond milk draws less fresh water than cow’s milk in Poore and Nemecek’s 2018 data, 371 litres to 628, but more per gram of protein or weighted for scarcity (2023 review).

Ocean dead zones are a meat problem as well as a fertiliser one: a 2023 Oxford study found UK vegans’ diets caused 27% of the nutrient pollution of diets with 100g or more of meat a day.

Per kilogram, avocados and quinoa emit far less than meat: estimates put them at 0.6 to 2.5kg of CO2-equivalent, against a mean of 9.9kg for poultry in Poore and Nemecek’s 2018 data. Avocado farming has real local water costs.

Eating local does little for your food’s carbon footprint: in Poore and Nemecek’s 2018 data, transport is about 6% of food’s emissions and 0.5% of beef’s, so what you eat matters far more than where it came from.

Factory farming helps new diseases emerge, says a 2020 UN report, and the 2009 flu pandemic, from pigs in Mexico, killed 151,700 to 575,400 people in its first year (US CDC, 2012). Wildlife is still the commonest source.

Slaughterhouse jobs are a weak case for meat: US meat and poultry workers are seriously injured at twice the average rate (Labor Department, 2024). Eating more plants would cut those jobs and create others, a 2026 review found.

Cultivated meat isn’t grown from cancer cells: some lines are immortalised, which is only one of cancer’s traits, and no study has shown it causes cancer. It was first approved in 2020, so long-term data are lacking.

Lab-grown meat could emit far less than beef: CE Delft (2023) projected 92% less than beef from beef herds on renewable power. On fossil-heavy energy or pharmaceutical-grade growth medium, that lead shrinks or reverses.

Lab-grown meat is unlikely to match ordinary meat on price as made now, a 2024 review of cost studies found. David Humbird’s 2021 model put the cells alone at $37 a kilo to make, more than double the price of US mince.

Lab-grown meat is animal tissue grown from animal cells, and regulators in Singapore (since 2020), the US, Israel, and Australia and New Zealand have assessed products and let them go on sale. Long-term data are lacking.

The case for farming fewer animals doesn’t rest on plant-based or lab-grown meat: Poore and Nemecek (2018) found that dropping animal products, using existing farming methods, would cut food’s land use by 76%.

Lab-grown meat is legal to sell in only a few countries, including Singapore, Israel, Australia and the US, where five products were cleared by February 2026 (FoodNavigator). The UK and EU have approved none for people.

Meat substitutes can help meat eaters cut down: in a 2022 Oxford trial, free ones with leaflets cut meat eating by 63g a day. The trial is unreplicated, and putting them in one chain’s meat aisles did not cut meat sales.

Plant-based meat is usually ultra-processed, but processed meat is the proven cancer risk: in 2015 IARC found each 50g a day raises bowel cancer risk by 18%. Trials found no harm to LDL; one found poorer blood sugar.

Precision-fermented proteins come from genetically modified microbes, which have made insulin since 1982 and chymosin for US cheese since 1990. Brewed whey is a milk allergen, and brewed casein may differ from the cow’s.

Fortified soya or pea drink comes nearest to cow’s milk: per 100g, soya averaged 2.8g of protein, pea 3.5g and milk 3.3g (US, 2022). EU reviews cleared the gums used; a 2024 French observational study linked two to diabetes.

Vegan cheese still trails dairy on taste, but melting depends on the brand: in a 2025 NC State University test, 89% said one vegan mozzarella looked melted about right on pizza and 98% said another hadn’t melted enough.

Going vegan tends to be hardest early on: a 2024 review by Singh and colleagues found new eating and exercise habits usually took two to five months to become automatic. B12 needs a fortified food or supplement.

A vegan diet of grains and pulses can cost less than eating meat: a 2021 Oxford model put it 22 to 34% below current diets in richer countries. A diet with a little meat saved 12 to 14%, and some studies found no saving.

A flexitarian diet does real good, but a vegan one goes further: in a 2023 Oxford study of UK diets, low meat-eaters (under 50g a day) had about half the food emissions of those eating 100g or more, and vegans a quarter.

Veganuary is a free January vegan pledge from a UK charity. In its 2026 survey 35% of respondents were fully plant-based six months on, but only 0.5% of those asked replied, and two supermarket studies found meat sales unchanged.

Cheese can be hard to give up but is not uniquely addictive: when 384 adults in a 2015 University of Michigan study rated 35 foods for addiction-like eating problems, cheese came 10th, behind pizza and chocolate.

Vegan cooking needn’t take long, because tinned pulses come ready cooked: a 2010 BBC Good Food recipe makes falafel burgers from a tin of chickpeas in 16 minutes. As in any cuisine, some dishes take an hour.

Slipping up on a vegan diet doesn’t undo the good you’ve done: Animal Charity Evaluators’ rough 2021 estimate links each plant-based person to about 105 fewer vertebrates killed a year, and one meal takes back only its share.

Craving meat rarely means your body needs it: cravings are mostly learned, and in a 2017 analysis of 367 US dieters (POUNDS Lost), eating a craved food less often went with craving it less. The first days can be harder.

Many wines and cask ales aren’t vegan, because they are cleared with isinglass from fish bladders, gelatine, milk casein or egg white. Carmine (E120), shellac (E904) and wool-derived vitamin D3 come from animals too.

Being vegan rarely cuts people off: in a 2026 study of 5,000 adults in Germany, vegans had as much social contact and support as meat eaters, and felt only slightly more isolated once depression was allowed for.

Eating out as a vegan is rarely impossible: a guide by the campaign group PETA, updated in 2026, lists vegan food at 61 UK chains. Indian and Chinese menus often work too, if you ask about ghee, egg and oyster sauce.

Cooking vegan for a meat-eating family can work, though in a Finnish survey published in 2026, 29% of women living with children said others’ tastes stopped them making vegetarian food. Cook one meal the others add to.

Cooking for a vegan means leaving out meat, fish, dairy, eggs, honey and gelatine, and most of a roast or an everyday dinner needs only small swaps. The usual traps are stock, butter, glazes, sauces and wine.

Vegan children can join in at school and parties with planning, like a packed lunch and a word with the host. Surveys on teasing and exclusion are few, small and mixed, and paediatricians advise a daily B12 supplement.

Eating vegan when travelling takes some planning but is rarely hard in cities: the guide app HappyCow counted 244,584 businesses with vegan options in 2024, most not fully vegan. Pack food and order plane meals ahead.

Extreme protest can cost the animal cause support, yet the case can still shift behaviour: Schwitzgebel and colleagues (2020) found meat in students’ larger campus purchases fell from 52% to 45% after meat-ethics classes.

The word vegan puts many people off, partly through the image it carries: MacInnis and Hodson (2017) found meat eaters rated vegans and vegetarians as badly as, or worse than, several groups that often face prejudice.

Talking to friends and family about veganism works better as an exchange than a lecture: in Kalla and Broockman’s 2020 study on immigration, arguments alone did nothing measurable, but swapping stories shifted views slightly.

Feeding a cat meat isn’t hypocrisy for a vegan: cats are obligate carnivores, and the British Veterinary Association said in 2024 that a complete vegan diet for cats isn’t currently possible.

Keeping a pet isn’t exploitation if you adopt one that needs a home and put it first: US shelters and rescues euthanised 597,000 dogs and cats in 2025, Shelter Animals Count says. Breeding pets to sell is harder to defend.

A dog can be fed a plant-based diet but a cat can’t yet be given a complete vegan one, the British Veterinary Association said in July 2024, warning that long-term data on dogs are lacking.
