Why vegan

The reasons, with the evidence behind each one

Parents deserve reasons that hold up. So here is the case for raising a child vegan on three fronts, health, compassion, and the world they will inherit, with the strongest evidence stated plainly and the honest limits stated just as plainly.

Health: a well-planned vegan diet is healthful at every stage of life

Do major health organizations say vegan diets are appropriate for children?

The largest body of nutrition professionals in the United States, the Academy of Nutrition and Dietetics, has concluded across position papers spanning more than three decades that appropriately planned vegetarian and vegan diets are healthful and nutritionally adequate. Its 2016 position stated that this holds “for all stages of the life cycle, including pregnancy, lactation, infancy, childhood, adolescence, older adulthood, and for athletes.” Its current 2025 position, scoped to adults, adds that these patterns can offer long-term health benefits, particularly for cardiometabolic disease. The British Dietetic Association affirms that well-planned vegan diets can support healthy living at all ages, including pregnancy and breastfeeding, the NHS publishes practical guidance for vegan pregnancy, babies, and children, and the Nordic Nutrition Recommendations 2023 conclude that a well-planned vegan diet with supplementation can be adequate for infants and children with monitoring. The American Academy of Pediatrics, in its Pediatric Nutrition handbook, treats appropriately planned vegetarian and vegan diets as able to meet children’s needs while stressing supplementation and monitoring (its wording varies by edition, so consult the current edition to quote it precisely). Even the most cautious major body has moved: the German Nutrition Society, long cited by critics as the authority that would not endorse vegan diets for children and pregnancy, updated its position in 2024 and now says it cannot make a clear recommendation either in favour of or against one for these groups, provided B12 is supplemented and the diet is well planned with qualified guidance. That is a softening from an outright non-recommendation.

Honesty requires the other side of the ledger too. Europe’s paediatric gastroenterology society, ESPGHAN, reviewed the childhood studies in 2025 and concluded that a nutritionally complete vegan diet supporting normal growth is “potentially achievable but cannot be confirmed” with current evidence, and requires supplementation and monitoring. That is a finding of limited evidence and a need for care, not a finding of harm, and applied consistently it would rule out nearly all specific childhood dietary advice, since almost none of it rests on lifetime trials. The bodies that are cautious cite thin evidence. None cite demonstrated harm from a well-planned diet.

Does a vegan diet reduce the risk of chronic disease?

The diseases that shorten and worsen most lives in wealthy countries, heart disease, type 2 diabetes, high blood pressure, several cancers, and obesity, are the ones a well-planned plant-based diet is most consistently linked to preventing.

For the deeper dives, see what the Adventist Health Studies actually show, how cholesterol drives heart disease, and why plant-based eating keeps weight healthy.

Why does childhood matter for diseases that appear decades later?

Because the runway is longer than people think. Autopsy studies of children and young adults, the Bogalusa Heart Study and the PDAY study, found the earliest streaks of artery disease already forming in childhood and adolescence, tracking with cholesterol levels. The cholesterol and the habits of childhood are not waiting for adulthood to start mattering. They are already writing the first lines of the story.

What are the honest limits of the health evidence?

Most of this evidence is observational, and people who go vegan also tend to smoke less, drink less, and exercise more; no study fully removes that advantage. It is not all one-directional: EPIC-Oxford also found vegetarians had a slightly higher risk of stroke, and the vegan-specific reduction in all-cause mortality in the Adventist cohort did not reach statistical significance on its own, so I will not tell you vegans are proven to live longer. The direction and consistency of the cardiometabolic benefit is real; the certainty is strong and reasonable, not absolute. That is still firmer ground than the standard diet stands on, which has never cleared that bar either and produces the very outcomes we are trying to spare our children. The full, honest picture for children, including growth, bone health, and infancy, is in the complete guide to raising children vegan.

Compassion: values your child already has

Do children naturally care about animals?

Yes, and not as a sentimental guess; this is measured. When researchers give children moral dilemmas about humans and animals, children extend far more moral concern to animals than adults do. In a 2021 study in Psychological Science, children aged five to nine valued human, dog, and pig lives roughly equally, while adults would save one human over as many as a hundred animals. The authors concluded that the view that humans matter overwhelmingly more appears late in development and is socially acquired. A 2023 study found children were less likely than adults to categorize farm animals as food, thought farm animals deserved better treatment, and judged eating animals as less morally acceptable. And when children who had independently chosen vegetarianism inside meat-eating families were asked why, every one of them pointed to not wanting to hurt animals.

Raising a child vegan is therefore not imposing an adult ideology on a blank slate. For many children it removes the conflict between what they are fed and what they already feel. One finding keeps this honest and kind: those same vegetarian children did not condemn others for eating meat. Tolerance, not superiority, is the natural childhood posture, and it is the one to nurture.

How many animals are killed for food?

The scale is the reason a vegan diet is the only common way of eating that asks no animal to be harmed for the plate. If you have heard that crops kill animals too, the arithmetic has been done, and it runs the other way: the crop deaths argument, counted honestly.

The planet: a world worth inheriting

How much does animal agriculture cost the environment?

The largest analysis of the global food system, covering roughly 38,700 farms in 119 countries (Poore and Nemecek, Science, 2018), found that livestock occupy about 83 percent of the world’s farmland while supplying about 18 percent of its calories and 37 percent of its protein. The food system produces roughly a quarter of human-caused greenhouse gas emissions, with animal products responsible for most of that share, and cattle pasture is the single largest driver of tropical deforestation, at around 41 percent. Shifting the world to plant-based eating could cut agricultural land use by roughly three quarters while still feeding everyone, freeing land for forests, carbon storage, and wildlife.

Each figure above links to the full argument, including the honest answer to the common objection that livestock only eat food humans cannot.

Public health: safer for everyone’s children

Does animal farming drive pandemics and antibiotic resistance?

Roughly three quarters of the world’s antibiotics are used in farmed animals, and antimicrobial resistance was directly responsible for an estimated 1.27 million deaths in 2019 and associated with nearly five million, more than HIV or malaria. The CDC estimates that three out of every four new or emerging infectious diseases in people come from animals, and the recent record is not abstract: H5N1 avian influenza spread through United States dairy herds in 2024, infecting farm workers, with the first American death recorded in January 2025. Crowded, intensive animal farming is the incubator. Reducing demand for its products reduces the risk to every family, vegan or not.

Kinder work: nobody’s job should be violence

Are slaughterhouse jobs dangerous?

Slaughterhouse and intensive-farming work carries documented physical harm, with amputation and injury rates well above manufacturing averages, and documented psychological harm, with elevated depression, anxiety, and trauma symptoms reported in a 2023 systematic review of slaughterhouse workers. In the first year of the pandemic, a congressional investigation counted at least 269 worker deaths at the five largest United States meatpackers. Growing food from plants asks no one to kill for a living. A vegan food system is kinder to the people who feed us, not only to the animals.

Integrity: a life that matches its values

Most people, and children especially, do not want to see an animal hurt. That is no longer just an observation; the developmental research above measures it. A vegan diet is the only common way of eating that lines up with that feeling instead of asking a child to quietly set it aside at mealtimes. It is compassionate, sustainable, and safer, and it is the one way of eating a child never has to unlearn their own kindness to keep. Held gently, without superiority toward anyone who eats differently, it is simply a life that matches its values.
