The perception of plant-based foods as superior is largely shaped by corporate marketing rather than balanced evidence. This paper examines the role of industry influence, safety concerns related to plant-based foods, and the evolutionary context of human diets, challenging the widely promoted narrative that plant-based diets are inherently healthier or more sustainable. It calls for rigorous scrutiny of the plant-based narrative to ensure informed and balanced consumer choices in a landscape increasingly dominated by corporate interests.

1. Corporate Influence and Public Perception: The Bias Favoring Plant-Based Diets
1.1 The Corporate Drive Behind the Plant-Based Industry
Food industry giants such as Nestlé, Unilever, and PepsiCo have aggressively acquired or developed plant-based brands, channeling substantial resources into advertising and product innovation to position themselves at the forefront of this market. These corporations have shaped public perception through extensive marketing, promoting plant-based foods as a superior choice over animal products and cementing their influence on global food trends.
In recent decades, major corporations have propelled the global shift toward plant-based products, heavily investing in plant-based alternatives to capture emerging market opportunities. Companies in agribusiness, biotech, and food production sectors, such as Nestlé, Unilever, and PepsiCo, have strategically driven the plant-based trend by leveraging their power to portray plant-based foods as superior options and using their resources to position them as inherently ‘healthy,’ ‘sustainable,’ and ‘ethical’ choices. Through substantial investment and targeted marketing, these corporations have significantly influenced consumer perceptions and global food trends, promoting plant-based products as superior options in the marketplace(1-4). Companies like Nestlé, Unilever, and PepsiCo have strategically invested in plant-based alternatives, positioning them as healthy, sustainable, and ethical choices(3,4). These corporations have employed various strategies to maintain their influence, including regulatory capture, relationship building with stakeholders, and market-based approaches(5). The food industry has capitalized on nutritionism to enhance its power in global markets(2) and has embraced digital technologies to improve food system outcomes(6). While plant-based alternatives are often presented as resistance to corporate agri-food systems, they may actually reinforce corporate dominance(7). This corporate influence extends to global food governance, raising concerns about transparency and accountability(8).
1.2 Marketing Campaigns and Sponsored Research
Marketing Campaigns and Health Claims: Through extensive marketing campaigns, corporations have reinforced a narrative that plant-based foods are inherently healthier and more environmentally friendly than meat-based foods. A recent study published in Business Strategy and the Environment analyzed over 16,000 marketing and labeling content observations from major US e-commerce grocery retailers(9). It found that plant-based foods (PBFs) were more robustly marketed than animal-sourced foods (ASFs), with an average of 47 claims per product compared to 28 for ASFs. PBFs tended to emphasize sustainability and health benefits, catering to consumer values around environmental stewardship and personal wellness(9,10).
In addition to advertising, many companies sponsor studies and partner with research institutions to generate findings that support plant-based diets, sometimes funding selectively published research that favors their products. Research suggests that industry sponsorship of nutrition studies may bias results and conclusions in favor of sponsors’ interests. Industry-funded studies are more likely to report favorable outcomes for sponsors’ products(11-13) and interpret neutral results positively(14). Sponsored research often focuses on topics that benefit industry, such as physical activity rather than processed foods(15). While some analyses found no significant difference in conclusions between industry and non-industry studies(16), others identified clear bias(17). Industry funding can influence study design, conduct, and publication(18). Historically, food companies have deliberately manipulated research to support their products and minimize perceived harms(17). Though sponsored studies may not differ in methodological quality, they tend to have conclusions favoring sponsors that are sometimes unsupported by the data(13,14).
This narrative is further amplified by partnerships with influencers and celebrities, who promote plant-based eating as a trendy lifestyle choice. The corporate influence over research, advertising, and public discourse has contributed to a widespread belief that plant-based foods are superior to meat, often without a balanced view of the evidence.
2. Safety Concerns with Plant-Based Foods: Natural Toxins and Man-Made Pollutants
2.1 Naturally Occurring Toxins in Plants
Plant-based foods offer essential nutrients but also contain natural toxins, which evolved as protective mechanisms against predators. Examples include lectins, oxalates, phytic acid, glycoalkaloids, pyrrolizidine alkaloids, cyanogenic glycosides, and solanine(19-23). Lectins, found in legumes and grains, can interfere with nutrient absorption and damage the gut lining(24). Oxalates, present in foods like spinach and nuts, may contribute to kidney stones and hinder calcium absorption(24), while phytic acid binds essential minerals, reducing their bioavailability(25). Other concerning toxins include pyrrolizidine alkaloids, cyanogenic glycosides, and solanine(22). Gluten, found in wheat, barley, rye, spelt, and triticale, is traditionally not classified as a toxin but may act as one in certain contexts. Its component gliadin can increase intestinal permeability by triggering zonulin release, disrupting tight junctions between intestinal cells, and potentially causing inflammation and autoimmune responses in susceptible individuals(26-30). While measures can reduce the harmful health impacts of natural toxins in plant-based foods, the assumption that they are inherently safer or superior to meat-based foods is both unfounded and potentially harmful.
