It happens at almost every family dinner, office potluck, or first date. Someone notices the plant-based plate, and the questions start rolling in. Where do you get your protein? Don’t plants feel pain too? What if you were stranded on a desert island?
Most vegans don’t mind the occasional curious question. What wears them down is the repetition — the same handful of talking points, decade after decade, as if no one has ever asked before. This isn’t about picking a side in the meat-versus-plants debate. It’s about the specific, recurring moments that make vegans quietly sigh into their lentil soup.
Here are 13 of the most common things vegans say they’re tired of explaining, the more nuanced reality behind each one, and a few common mistakes that tend to fuel the same tired arguments in the first place.
Key Takeaways
- Most vegan frustrations aren’t about defending the diet itself, but about answering the exact same questions repeatedly.
- Protein, willpower, and ‘what about plants feeling pain’ are the three most repeated talking points vegans encounter.
- Many misconceptions come from outdated nutrition assumptions rather than current research.
- A handful of genuine caveats — like B12 supplementation and reading menu labels carefully — are worth taking seriously, even if the rest of the myths aren’t.
- Understanding these recurring conversations can make dinner-table discussions less tense for everyone involved.
Questions About Nutrition and Health
This is the category that comes up first, fastest, and most often. It usually starts with genuine curiosity, but after the hundredth time, it starts to feel less like a conversation and more like a pop quiz.
1. Where do you get your protein?
This is the question. The one every vegan has answered more times than they can count, often before they’ve even started eating.
The honest answer is that plenty of plants carry meaningful protein — lentils, chickpeas, tofu, tempeh, edamame, quinoa, and seitan among them. A cup of cooked lentils has around 18 grams of protein, roughly comparable to three eggs, and a block of tofu can easily supply 20 grams per serving.
According to the Harvard T.H. Chan School of Public Health, most adults in the U.S. already get more protein than they need, and a well-planned vegan diet can meet requirements without much difficulty.
The most common mistake newcomers make isn’t a lack of protein sources, it’s relying on a single food (like plain rice) and forgetting to combine legumes, grains, nuts, and seeds across the day for a fuller amino acid profile. For readers curious about specifics, this rundown of high protein foods for vegans covers the numbers in detail.
2. Isn’t it expensive to eat vegan?
The image of vegan eating as an endless parade of specialty products and imported superfoods is a persistent one. In reality, some of the cheapest foods on any grocery list — rice, beans, oats, potatoes, canned lentils — happen to be vegan staples.
The cost climbs when someone leans heavily on packaged meat substitutes or exotic flours, but that’s a choice, not a requirement. A caveat worth admitting: eating vegan on a very tight timeline, in a food desert, or while traveling can genuinely cost more, since fresh produce and specialty items aren’t always accessible everywhere.
But for everyday home cooking, pantry basics like the ones in this list of cheap pantry staples that quietly became vegan protein powerhouses tend to cost less per serving than most meat.
3. Don’t you feel weak or tired all the time?
This assumption usually stems from outdated ideas about plant-based eating rather than current evidence. Fatigue in vegans, when it happens, is typically tied to poorly planned meals or missing nutrients like B12 and iron, not the diet itself.
One common mistake is quitting meat without replacing its calorie and iron density, leading to an unintentional drop in overall energy intake — that’s a planning issue, not a vegan-specific one.
A resource like what actually happens to your body in the first month of going vegan lays out the adjustment period honestly, including the parts that do require some attention.
4. What about B12 and other deficiencies?
This one is at least grounded in something real, which is why most vegans don’t mind explaining it once. B12 is genuinely harder to get from plants alone, and organizations including the Vegan Society recommend supplementation or fortified foods.
Iron and omega-3s are worth a mention too — plant sources like lentils and flaxseed exist, but iron absorption from plants improves significantly when paired with vitamin C, and algae-based omega-3 supplements are an easy fix for anyone skipping fish.
What gets tiring is when this single, well-managed nutrient becomes shorthand for ‘the whole diet must be unhealthy,’ when in practice it’s a five-second daily supplement, not a crisis.
Questions About Ethics and Motivation
Once nutrition is out of the way, conversations often pivot to philosophy. This is where things can get repetitive in a different way — less about facts, more about the same hypothetical scenarios on repeat.
5. What if you were stranded on a desert island?
Nearly every vegan has fielded this one, usually delivered as a gotcha. The response is almost always the same: hypothetical survival scenarios don’t really inform everyday grocery store decisions.
Choosing not to eat meat at a regular dinner isn’t undermined by a hypothetical emergency that will likely never happen, any more than owning a car is undermined by asking what you’d do if it broke down in the desert.
6. But plants feel pain too, right?
This argument gets raised often enough that it has become something of a running joke in vegan circles. Plants lack a central nervous system and the neurological structures associated with pain perception, which is a key distinction from animals.
It’s also worth noting that raising livestock typically requires growing large quantities of plant feed anyway, so even by this logic, eating plants directly tends to involve fewer plants harvested overall. Most vegans see this less as a serious biological claim and more as a conversational reflex.
7. Aren’t humans natural omnivores, so it’s fine to eat meat?
The debate over human anatomy and historical diets is a real and ongoing one among researchers, but it rarely settles the personal question of why someone chooses to eat the way they do today.
Most vegans aren’t arguing about paleolithic biology; they’re making a decision based on their own current values, which doesn’t require winning an anthropology debate first.
8. If everyone went vegan, wouldn’t farm animals lose their homes?
This one imagines an overnight, all-or-nothing global shift that isn’t how dietary trends actually happen.
Change, if it comes, tends to be gradual, and it’s a strange standard to hold vegans to a hypothetical mass-scale scenario when no other food choice is judged the same way — nobody asks meat-eaters to account for what would happen to global cattle populations if everyone suddenly ate steak three times a day.
Questions About Daily Life and Social Situations
Beyond nutrition and ethics, there’s a whole category of assumptions about what vegan life actually looks like day to day — often based on very little firsthand experience.
9. Isn’t vegan food bland and boring?
This idea tends to fade the moment someone actually tries something like a vegan mushroom pasta or a slice of vegan garlic bread with herb butter. Cuisines across the globe have relied on plant-based cooking for centuries, long before the word ‘vegan’ existed, as explored in this look at countries where vegan food was invented long before it was trendy.
A common mistake beginners make is assuming a plate just needs the meat removed, when the real trick is building flavor through spices, umami-rich ingredients like mushrooms and miso, and proper seasoning, the same way any good dish is built.
10. Do you judge people who eat meat?
Plenty of vegans go out of their way to avoid moralizing at the dinner table, yet they’re still braced for this question at nearly every meal. Personal food choices and public judgment aren’t the same thing, and most vegans would rather just eat their meal in peace.
11. Isn’t vegan junk food actually healthy just because it’s vegan?
This misconception runs in the opposite direction of most assumptions on this list, and vegans are often the ones correcting it.
Vegan doesn’t automatically mean nutritious — plenty of processed vegan snacks are just as high in sugar, sodium, or saturated fat as their meat-based counterparts, a point covered thoroughly in 13 vegan junk foods that are just as unhealthy as their meat versions.
Coconut oil-based vegan cheeses and fried plant-based nuggets are two frequent offenders that surprise people expecting an automatic health upgrade.
12. Isn’t it impossible to eat out or travel as a vegan?
Eating out does require more research than it used to, but the landscape has changed dramatically, with most major cities offering plant-based menus or clearly labeled options.
The bigger challenge is often decoding menu language, since some dishes that sound plant-based quietly aren’t — refried beans made with lard, bread brushed with butter, or soup stocks built on chicken broth, as detailed in 14 restaurant menu items that sound vegan but almost never are.
A useful habit is simply asking about the stock or fat used before ordering, rather than assuming a dish labeled ‘vegetable’ is automatically safe.
13. Won’t you just give up eventually, like everyone else?
This one stings a little because it assumes failure before anything has even started. Plenty of people do find certain foods hard to quit, but that’s true of any dietary change, not unique to veganism — a reality covered honestly in 13 foods that are harder to give up than meat, according to former vegetarians.
Plenty of others, including public figures profiled in 13 celebrities who gave up meat, stick with it for years, often finding it easier over time as habits and go-to recipes settle in.
Frequently Asked Questions
Is it true that vegans can’t get enough protein without meat?
No. Foods like lentils, chickpeas, tofu, tempeh, and quinoa provide substantial protein, and most nutrition guidelines confirm a well-planned vegan diet can meet standard protein requirements. The key is variety, not any single ‘miracle’ food.
Do vegans need to worry about nutrient deficiencies?
Vitamin B12 is the main nutrient of concern, since it’s not naturally present in plant foods in reliable amounts. Most health organizations recommend a supplement or fortified foods to cover it, and iron or omega-3 intake can also benefit from a little extra attention, though neither requires drastic measures.
Why do vegans get frustrated by the ‘what about plants feeling pain’ question?
Because it’s raised so frequently as a conversational deflection rather than a genuine biological argument. Plants lack the nervous system structures associated with pain perception in animals, which is the usual basis for the ethical distinction.
Is all vegan food automatically healthier than food containing meat?
Not necessarily. Many processed vegan snacks and convenience foods contain high levels of sugar, sodium, or saturated fat, similar to their non-vegan counterparts, so it’s worth reading labels rather than assuming.
Is eating out as a vegan really as hard as people assume?
It has gotten considerably easier in most areas, though some menu items that sound plant-based aren’t always fully vegan, so a bit of reading or asking about hidden ingredients like stock or butter is often still necessary.
