Despite veganism’s moral and environmental appeal, emerging evidence suggests a more nuanced reality—one where biology, culture, and sustainability rarely fit into a single diet. November is World Vegan Month. Is the diet right for you, or very wrong?
Veganism has grown from a fringe lifestyle into a mainstream movement. Grocery stores boast plant-based meat alternatives, restaurants label vegan options on menus, and influencers share recipes promising health, compassion, and sustainability. For many, it feels like the obvious moral choice. Yet a quieter counterargument exists: reasons why some people, even those who care deeply about animals, health, and the planet, choose not to be vegan.
This is not about dismissing veganism but about examining the complexities that are often overlooked in the conversation. Food is personal, cultural, and biological, and the reasons not to be vegan are as varied as the individuals who hold them.
Health Considerations Beyond Plants
Proponents of veganism often tout its health benefits, pointing to lower rates of heart disease, type 2 diabetes, and obesity among plant-based eaters. While these outcomes are supported by research, the story is not so simple. Some nutrients are difficult, though not impossible, to obtain without animal products.
Vitamin B12, for example, is found almost exclusively in animal-derived foods. Vegans must rely on supplements or fortified products to avoid deficiency, which can cause anemia and neurological problems. Omega-3 fatty acids, particularly DHA and EPA, are another challenge. These are essential for brain health and are most efficiently sourced from fatty fish. While algae-based supplements exist, they are not part of most traditional food systems.
Iron and zinc are also less bioavailable in plant foods, meaning the body absorbs them less effectively. For individuals with higher nutritional needs such as children, pregnant women, or those with certain health conditions, animal products can provide a more reliable foundation.
Some people find that, despite careful planning, a vegan diet leaves them fatigued, bloated, or dealing with other digestive issues. While science shows veganism can be healthy, it is not universally suitable, and for some, it may even compromise well-being.
The Environmental Paradox
One of the most common arguments for veganism is that it reduces environmental impact. Indeed, animal agriculture is linked to greenhouse gas emissions, deforestation, and water use. But here, too, the picture is complicated.
Not all meat is created equal. Beef raised on deforested land in the Amazon has a vastly different footprint than grass-fed cattle raised on marginal pastureland in the U.S. or Europe. In many regions, livestock graze on land unsuitable for crops, effectively converting inedible grasses into nutrient-rich food. Removing these systems could mean losing a sustainable food source that humans have relied on for millennia.
Monoculture crop farming, which underpins many vegan staples like soy, wheat, and corn, also contributes to biodiversity loss, soil depletion, and pesticide use. Almonds, a favorite plant-based milk ingredient, demand enormous amounts of water, straining ecosystems in drought-prone California.
While reducing industrial meat production is important, rejecting animal agriculture entirely may not be the most balanced or environmentally sound solution. Regenerative grazing, for example, has been shown to restore soils, sequester carbon, and support wildlife habitats. A nuanced approach—less but better meat—might serve the planet better than strict veganism.
Cultural and Historical Roots of Food
Food is more than fuel; it is a cornerstone of culture, identity, and tradition. Around the world, animal products play a central role in rituals, celebrations, and daily life. From Thanksgiving turkey in the United States to sheep sacrificed for Eid al-Adha, these foods carry meaning that transcends nutrition.
In many Indigenous cultures, hunting and animal stewardship are deeply spiritual practices. These communities often view animals not as commodities but as beings to be respected, harvested with gratitude, and used fully. To dismiss these practices as unethical overlooks their ecological wisdom and cultural significance.
For families and individuals with strong culinary traditions, eliminating animal products can feel like erasing heritage. Sharing a Sunday roast, making chicken soup passed down through generations, or eating fish caught by hand are experiences loaded with memory and belonging. Veganism, in this context, may feel like disconnection.
The Economic Argument
Another layer of complexity is economics. For some, a vegan diet is not financially or logistically feasible. Meat, dairy, and eggs are often accessible and affordable sources of protein, especially in communities with limited food options. Fresh produce and specialty vegan substitutes can be more expensive and less available, particularly in food deserts or developing countries.
Globally, billions of people rely on animals not only for food but for livelihoods. Farmers, herders, and fishers sustain families and communities through animal agriculture. A world without animal farming would demand a massive restructuring of economies, which could devastate rural communities.
Ethical Gray Areas
The ethical foundation of veganism is compassion for animals, but even here the debate is not clear-cut. Industrial farming undeniably raises serious welfare concerns. Yet not all animal agriculture operates under such conditions. Small-scale farms, pasture-based dairies, and local fisheries often provide animals with lives far removed from the suffering of factory farms.
Some argue that death is a part of life and that humans, as omnivores, are part of that cycle. Others point out that plant agriculture is not free of harm either. The production of crops involves pesticides, habitat destruction, and machinery that inadvertently kills small animals. While the scale of suffering may differ, no diet is completely without ethical cost.
The Personal Factor
Finally, one of the strongest reasons people cite for not being vegan is simple: personal preference. Taste, satisfaction, and enjoyment are valid considerations in a world where food is deeply tied to happiness and quality of life. For some, the occasional steak, cheese platter, or holiday roast is not just a craving but a joy that contributes to overall well-being.
Rigid dietary rules can also foster guilt, shame, or disordered eating patterns. For those who have struggled with restrictive diets, veganism may feel like another form of control rather than liberation. Flexibility—sometimes called “flexitarianism”—can offer a middle path, allowing people to eat more plants while still enjoying animal products in moderation.
A Broader Perspective
The choice not to be vegan does not necessarily mean ignoring animal welfare, health, or sustainability. Many people who reject strict veganism still make conscientious food choices. They might buy eggs from backyard chickens, choose dairy from small family farms, or support fisheries that follow sustainable practices. They may commit to reducing meat consumption, prioritizing quality over quantity.
This more individualized approach acknowledges the realities of biology, culture, and environment while still striving for positive impact. It suggests that the question is not simply “vegan or not,” but “how can I eat in a way that aligns with my values and circumstances?”
The Takeaway
Veganism is a powerful movement, offering a vision of compassion and sustainability. For some, it works beautifully. But it is not the only ethical, healthy, or environmentally conscious way to eat. The reasons not to be vegan, whether nutritional, cultural, environmental, economic, or personal, deserve to be heard without dismissal.
Food is never just about nutrients or ideology. It is about survival, history, joy, and connection.Choosing not to be vegan does not mean turning away from responsibility; it can mean engaging with it in a way that feels grounded, realistic, and sustainable for the individual and their community.
In the end, the goal may not be perfection but progress and eating in ways that nurture both people and the planet, however that looks on each plate.
10 Vitamins and Minerals All Older Adults Need to Prioritize in 2025
Grandma’s everyday multivitamin probably won’t cut it anymore. From the moment we turn 65, we’re nutritional renegades, requiring more of some and stubbornly consuming less of others.
Consider this wake-up call: nearly 20% of older Americans lack adequate vitamin D, and an astonishing 46%, or about half, fall short of the recommended amount of protein. These are not statistics; these are the roots of independence, mental acuity, and vitality that infuse life to its fullest rather than survival. Learn more.
