Plant-based meat alternatives have the highest consumer acceptance, while lab-grown and insect-based proteins face significant barriers including poor taste, high prices, and psychological rejection—with many people not viewing them as real food. According to Gram Research analysis of 61 studies across 29 countries, plant-based alternatives overcome these obstacles better than other alternatives, though acceptance varies by culture and requires both product improvements and consumer education to scale.
A major review of 61 studies across 29 countries examined why people accept or reject meat alternatives like plant-based burgers, lab-grown meat, and insect protein. According to Gram Research analysis, plant-based foods are gaining acceptance, but lab-grown and insect-based alternatives face significant hurdles. The biggest obstacles aren’t just taste and price—many people don’t even see these new foods as “real food.” While environmental and health benefits matter to consumers, they rarely overcome concerns about how these alternatives taste, where to find them, and whether they’re worth trying. The research suggests that scaling these alternatives will require both better products and smarter marketing.
Key Statistics
A systematic review of 61 studies from 29 countries published in Current Developments in Nutrition (2024) found that plant-based meat alternatives have the highest consumer acceptance, while lab-grown and insect-based alternatives face the lowest acceptance due to taste concerns, unfamiliarity, and psychological barriers.
Research analyzing consumer attitudes across 29 countries identified five key barriers preventing adoption of all meat alternatives: poor sensory qualities like taste and texture, limited store availability, high prices, unfamiliarity with products, and perceived inconvenience in preparation.
A 2024 literature review of 61 consumer studies found that perceived environmental and health benefits alone rarely overcome barriers to meat alternative adoption—consumers require multiple positive factors including good taste, reasonable price, and easy availability to switch from conventional meat.
Analysis of 61 studies from 2000-2024 revealed that some consumers view lab-grown and insect-based proteins as not being food at all, expressing fear or disgust at eating them, whereas plant-based alternatives face primarily sensory and convenience objections rather than psychological rejection.
The Quick Take
- What they studied: Why people do or don’t accept meat alternatives like plant-based burgers, cultured meat grown in labs, insect protein, and foods made from algae or mushrooms
- Who participated: Analysis of 61 research studies from 29 countries published between 2000 and 2024, examining consumer attitudes and behaviors toward alternative proteins
- Key finding: Plant-based alternatives have the highest acceptance among consumers, while lab-grown and insect-based alternatives face the lowest acceptance due to taste concerns, unfamiliarity, and psychological barriers—with some people not viewing them as food at all
- What it means for you: If you’re curious about meat alternatives, plant-based options are most likely to satisfy you right now. Lab-grown and insect proteins need significant improvements in taste, availability, and consumer education before they’ll become mainstream, though acceptance varies by country and culture
The Research Details
Researchers conducted a systematic review, which means they searched two major scientific databases (Scopus and Google Scholar) for all published studies about how consumers feel about meat alternatives. They found 5,998 articles and carefully selected 61 high-quality studies that directly examined consumer acceptance of these products. The studies came from 29 different countries and covered research published over 24 years (2000-2024).
Instead of doing their own experiments, the researchers analyzed what other scientists had already discovered about why people accept or reject alternatives to meat, eggs, dairy, and fish. They organized the findings by type of alternative—plant-based (like Beyond Meat), cell-based (lab-grown), insect-based, algae-based, and fungi-based products. This approach allowed them to spot patterns across many different studies and countries.
The review examined both what stops people from trying these foods (barriers) and what encourages them to try them (facilitators). Researchers looked at sensory factors like taste and texture, practical factors like price and availability, and psychological factors like whether people see these products as legitimate food.
This research approach is important because individual studies might only look at one country or one type of alternative protein. By combining 61 studies, researchers could see the big picture: which alternatives are actually gaining acceptance and which face major obstacles. This helps companies, policymakers, and health advocates understand what needs to change for meat alternatives to become mainstream. Without this comprehensive view, we might waste resources promoting products consumers aren’t ready to accept.
This is a systematic review, which is a strong type of research that combines many studies to find patterns. The researchers searched multiple databases and included studies from diverse countries, making the findings more reliable than any single study. However, the quality depends on the individual studies they reviewed—some may have been small or limited to specific populations. The review covers 24 years of research, so it captures how attitudes have evolved, though newer studies may show different acceptance levels than older ones. The researchers were transparent about limitations and noted that evidence is sparse for some alternative types and regions.
What the Results Show
Plant-based alternatives show the highest consumer acceptance overall. These products, made from ingredients like soy, peas, and nuts, are most likely to be purchased and eaten regularly because they taste reasonably similar to meat, are widely available, and have improved significantly over the past decade. Many consumers see them as a practical way to reduce meat consumption without completely changing their diet.
Lab-grown meat (also called cultured or cell-based meat) and insect-based proteins face the lowest acceptance. The research shows this isn’t just about taste or price—many consumers express fear or disgust at the idea of eating these products. Some people don’t even view lab-grown meat as “real food” because it’s made in a laboratory, and insects trigger psychological barriers that plant-based foods don’t. This suggests that acceptance of these alternatives requires more than product improvement; it requires changing how people think about what food is.
Across all alternative types, the same barriers repeatedly appeared: poor taste and texture, high prices, limited availability in stores, unfamiliarity with the products, and inconvenience in preparing them. Interestingly, even when consumers believed these alternatives were better for the environment or their health, these benefits alone rarely convinced them to switch from conventional meat. The research suggests that people need multiple reasons—good taste AND environmental benefits AND reasonable price—to make the change.
Acceptance varies significantly by country and culture. Some regions show much higher openness to alternatives than others, suggesting that cultural attitudes toward food, meat consumption patterns, and environmental concerns all influence whether people try these products. This means one-size-fits-all marketing strategies won’t work globally.
Algae-based and fungi-based alternatives received less research attention overall, making it harder to draw firm conclusions about consumer acceptance. However, the limited evidence suggests these products face similar barriers to plant-based alternatives—primarily taste and texture concerns—rather than the psychological rejection seen with lab-grown and insect products. Mushroom-based proteins, in particular, show promise because they’re already familiar foods that people eat regularly. The research also found that consumer attitudes toward meat alternatives are not fixed; they change over time as products improve, become more available, and as cultural attitudes shift. Marketing and education campaigns can influence acceptance, especially when they address specific concerns like taste or food safety.
This review updates and expands on earlier research by covering a longer time period (24 years) and more countries (29) than most previous studies. It confirms what earlier research suggested—that plant-based alternatives are gaining mainstream acceptance—but provides new insight into why lab-grown and insect proteins face such steep psychological barriers. Previous studies often focused on whether consumers would try these products; this review goes deeper by examining the specific reasons people accept or reject them. The findings align with market data showing that plant-based meat sales have grown significantly while lab-grown meat remains largely unavailable to consumers.
The review’s strength—combining many studies—is also a limitation because the individual studies varied in quality, sample size, and methodology. Some studies surveyed only a few hundred people, while others surveyed thousands. Some measured actual purchasing behavior, while others only asked hypothetical questions like “Would you try this?” (which often overestimates real acceptance). The research on insect-based and algae-based alternatives is limited, so conclusions about these products are less reliable. Additionally, the review only included studies published in English or available through the two databases searched, potentially missing relevant research from other regions. Finally, consumer attitudes change rapidly, and studies from 2000-2010 may not reflect current acceptance levels, especially as products have improved and become more visible in stores.
The Bottom Line
If you’re interested in reducing meat consumption, plant-based alternatives are ready to try now—they’ve reached a level of taste and availability that works for many people (moderate to high confidence). Lab-grown and insect-based alternatives are not yet practical for most consumers; wait for these products to improve in taste, become more affordable, and become more widely available before investing time or money in them (high confidence). For companies and policymakers, the research shows that simply promoting environmental or health benefits won’t drive adoption; products must also taste good, be affordable, and be convenient to find and prepare (high confidence).
Plant-based alternatives are worth trying for anyone interested in eating less meat, whether for environmental, health, or ethical reasons. People with specific dietary restrictions (vegetarian, vegan, allergies) may find these alternatives particularly useful. Lab-grown and insect-based alternatives are mainly relevant for researchers, food companies, and policymakers planning for future food systems—not yet for average consumers. People in countries with strong environmental concerns or higher acceptance of novel foods may find these alternatives more appealing than those in regions with strong meat-eating traditions.
Plant-based alternatives can make an immediate difference if you’re willing to try them—many people report enjoying them within their first few tries. Lab-grown meat may become available to consumers within 5-10 years in some countries, but widespread acceptance and affordability could take 15-20 years or longer. Insect-based proteins face even longer timelines for mainstream acceptance, possibly 20+ years, unless there’s a major shift in how people view insects as food.
Frequently Asked Questions
Why don’t more people eat plant-based meat if it’s better for the environment?
Environmental benefits alone don’t drive adoption. Research shows consumers need multiple reasons: good taste, affordable price, easy availability, and convenience. Plant-based alternatives succeed because they address these factors better than other alternatives, not just because they’re eco-friendly.
Is lab-grown meat going to replace regular meat soon?
Not soon. A 2024 review of 61 studies found lab-grown meat faces significant psychological barriers—many consumers don’t view it as real food and express fear or disgust. Widespread acceptance likely requires 15-20+ years of product improvement, price reduction, and consumer education.
What’s the biggest reason people reject insect-based protein?
Psychological rejection, not taste. Research shows many consumers view insects as disgusting or not food at all, regardless of nutritional benefits. This barrier is harder to overcome than taste or price concerns, requiring fundamental shifts in how people think about insects as food.
Do plant-based meat alternatives actually taste good now?
Good enough for most people. A 2024 analysis of 61 studies found plant-based alternatives have the highest consumer acceptance because taste and texture have improved significantly. However, preferences vary—some people love them, others find them acceptable but not identical to meat.
Which meat alternative should I try first if I’m new to them?
Start with plant-based alternatives that mimic foods you already enjoy—plant-based burgers if you like beef, or plant-based chicken if you prefer poultry. Research shows these have the highest acceptance and are most widely available, making them easiest to find and most likely to satisfy you.
