Who Gets to Define 'Vegan'? What Four Countries Actually Regulate

FDA regulations don't currently define "vegetarian" or "vegan." The agency said so directly in a draft industry guidance published in January 2025. That document is nonbinding and still in draft form, and it covers plant-based alternatives to eggs, seafood, poultry, meat and dairy. Its core recommendation is specificity: name the actual plant ingredient in a product's name, a "lentil burger" rather than a generic "plant-based burger." The US and Korea arrive at a similar place from opposite directions. Both focus their regulation on preventing consumer confusion rather than defining vegetarian identity itself. Korea built a new category, "alternative food," to do it. The US applies its existing labeling principles and simply leaves the vegetarian and vegan terms themselves undefined.

On school meals, one sentence carries most of the weight of this whole article. A USDA Food and Nutrition Service policy memo states plainly that offering vegetarian or vegan meals is a school's choice, not a requirement. General health concerns aren't disabilities and don't require a menu modification, and personal preferences tied to diet, religion or ethics are treated the same way, distinct from a disability. One state education department put it plainly: since being vegetarian or vegan is a personal preference, not a disability, program operators are encouraged, but not required, to offer vegetarian or vegan entrees.

Korea's answer was "a school principal's discretion." America's was "a personal preference, not a disability." Two entirely different legal systems drew the line in nearly the same place.

Whether a meal counts as a personal preference or as a condition of living is a fault line elsewhere too. On the first meal of the day, an official Japanese survey cut the numbers by household finances: nearly 40 percent of people worried about making ends meet rarely ate breakfast, against under 20 percent of the financially comfortable.

What the US did instead was widen how much plant-based food counts toward a meal's required protein. Tofu, soy yogurt and tempeh all earned specific crediting rules, and a 2024 final rule let nuts and seeds count for the full meat/meat-alternate component across all child nutrition programs. That rulemaking process saw real pressure for broader vegetarian and vegan access. The USDA's answer wasn't a mandate. It was more flexibility for schools to design menus that fit their own communities. Milk substitution, meanwhile, is still a school's option rather than an obligation, which is where a family looking for a vegetarian meal plan actually runs into its first real obstacle.

India requires a mark on packaged food showing whether it's vegetarian or not. Vegetarian gets a green circle inside a green-bordered square; non-vegetarian gets a brown triangle inside a brown-bordered square. The definition of non-vegetarian covers animal-derived ingredients broadly, but explicitly excludes milk and dairy. The mark doesn't apply to alcoholic beverages. India's food safety regulator administers the rule.

Vegan claims go a step further. Under a 2022 regulation, a business has to apply to the relevant licensing authority with test results and a self-declaration that no animal-derived ingredients were used, and only after approval can it print the designated logo. Line up the three systems side by side and the threshold heights fall into a clean order: India requires pre-approval, Japan requires voluntary certification, and the US requires nothing at all.

This article couldn't confirm who actually pushed for India's system. A connection to the country's food culture and religious traditions is a reasonable guess, but this article won't assert that without evidence behind it. What's confirmed is simpler: India is the country that stamps a shape on the package to settle the question, and its choice to exclude milk and dairy from "non-vegetarian" is itself a trace of that food culture built directly into the regulation.

Japan created two national agricultural standards (JAS) simultaneously in September 2022, one for vegetarian and vegan processed foods, the other for how restaurants serving vegetarian or vegan food should be managed. Pairing a food standard with a restaurant-management standard is a different design from countries that only regulate packaged goods. The processed-food standard doesn't treat "vegetarian" as one category; it splits into four: suitable for those who eat eggs and dairy, eggs only, dairy only, and vegan.

What actually triggered this wasn't a shift in Japanese eating habits. Ministry of Agriculture materials cite roughly 1.67 million vegetarian and vegan visitors among Japan's 2018 inbound tourists, and complaints about too few restaurants flexible enough to accommodate dietary requests. The standard was built for visitors. ISO 23662 arrived in March 2021, and Japan's own standards followed about a year and a half later, in September 2022, a sequence that suggests Japan referenced the international standard while building its own.

The system exists, but actual uptake still looks modest. Based on one certification body's published list, four years after the standards took effect, the number of certified businesses through that body sits in the single digits. That's not a national total, though; other certification bodies exist, so this doesn't settle how widely the standard has actually been adopted across Japan.

In 2020, the Green Party and a group of vegetarian elementary, middle and high school students and parents filed two constitutional complaints together. One argued that school meal regulations failed to account for vegetarian students in menu planning; the other argued that lawmakers had failed to legislate a right to vegetarian options in public meal programs. The Constitutional Court dismissed both. It found no constitutional basis for concluding that lawmakers were obligated to guarantee a vegetarian option in public meal programs, and it held that school menu planning is a principal's discretionary act, so the absence of a vegetarian choice couldn't be treated as a direct infringement of a constitutional right. The court didn't rule on whether a right to vegetarian choice exists. It sent the question back, saying that's a school principal's call, not a legislative one.

The demand didn't disappear, though. In June 2022, Seoul's education office installed "green meal bars" in 76 schools, aiming to give students a vegetarian option and build awareness around it, with officials also citing the educational value of respecting the rights of students who struggle to eat meat. The request the court dismissed got partially realized a couple of years later as a funded policy, not as a right.

The labeling side follows a similar pattern. What Korea's food safety ministry built isn't a "vegetarian labeling" standard; it's a guideline for "alternative foods," published in November 2023. It defines alternative food as products made mainly from plant ingredients, microorganisms, insects or cultured cells to resemble the taste and texture of existing animal-derived foods, and restricts using terms like "beef" or "milk" on products that don't contain them. The regulatory focus isn't what a vegetarian can choose. It's making sure something made of soy doesn't get mistaken for meat. The words "vegetarian" and "vegan" don't appear in that guideline at all. Vegan certification in Korea is currently handled entirely by private organizations, filling a space where no national standard exists.

There is pushback on the ground, too. Concerns about nutritional balance for growing teenagers surface among school kitchen staff. This article doesn't take a side on whether that concern is well-founded. The nutritional adequacy of a vegetarian diet for adolescents is a separate medical question that would need its own evidence, and this piece is about systems, not nutrition advice.
