Pepperoni: The Reliable Extrovert
A YouGov survey found that pepperoni is America’s favorite pizza topping, with roughly one in four people listing it as their number one choice. According to a poll of over 6,000 U.S. adults, pepperoni is the most-loved topping overall, with nearly two thirds of Americans saying they enjoy it.
One of the most studied personality dimensions in food psychology relates to extraversion, and extraverts tend to like more sensation – whether from the food they eat or other stimuli. They also tend to engage in more sensation-seeking behaviors than do introverts. The bold, salty, slightly spiced profile of pepperoni maps comfortably onto that pattern.
Dr. Alan Hirsch, director of the Smell and Taste Treatment and Research Foundation in Chicago, found that choices of pizza toppings can reveal personalities. In his research, pepperoni fans were associated with a tendency toward extroversion and a capacity for loyalty that cuts both ways.
Mushrooms: The Thoughtful Introvert
Mushrooms rank among the most loved toppings, with roughly four in ten Americans expressing strong enthusiasm for them, making them a consistent presence on the national favorites list. People who reach for mushrooms tend to be quieter in their choices – earthy, grounding, and unfussy.
Research suggests that more anxious individuals tend to have a greater number of food aversions, often due to neuroticism, while those who are emotionally settled tend to gravitate toward familiar, low-stimulation foods. Mushrooms fit that pattern well – they’re savory and satisfying without demanding attention.
According to Dr. Hirsch’s research, those who prefer a single vegetable topping tend to be empathetic, understanding, well-adjusted, and easygoing. Mushroom lovers often land in that category: steady, thoughtful, and genuinely comfortable in their own skin.
Extra Cheese: The Comfort Seeker
Sausage, mushrooms, and extra cheese are among the most popular additional pizza toppings among U.S. adults, with extra cheese claiming roughly half of consumers as fans. Choosing extra cheese is rarely about culinary ambition. It’s about warmth, softness, and feeling at home.
A person who gravitates toward sweet or indulgent foods might be seeking comfort during stressful times, indicating a meaningful connection between food choices and emotional states. Extra cheese sits squarely in the comfort camp – rich, familiar, and deeply satisfying.
The experience of taste appears to exert psychological effects upon the individual. Individuals subjected to a sweet or indulgent taste experience subsequently report greater intention to help others. Cheese lovers, it turns out, may be among the most generous people at the table.
Pineapple (Hawaiian): The Openness-to-Experience Type
Few toppings provoke stronger reactions. Pineapple on pizza divides rooms, workplaces, and family dinners with surprising force. Research published in the Journal of Scientific Psychology found that gender and age were the two primary predictors for the pineapple-on-pizza preference, with a tendency for younger females to prefer it and older males to dislike it.
Higher openness to experience correlates with a greater willingness to try unconventional food combinations and novel variants of familiar dishes. Research suggests that those who choose nontraditional toppings like pineapple tend to be aggressive, achievement-oriented, natural leaders who don’t suffer fools easily.
Conscientiousness has been shown to affect food choices and eating styles, with higher conscientiousness related to reduced consumption of sweet-savory food combinations – which may partly explain why the very conscientious types sometimes resist the Hawaiian pizza while the more free-spirited embrace it without hesitation.
Jalapeños: The Risk-Taker
Jalapeños on pizza represent a deliberate choice for heat – not an accident. Sensation seeking showed positive correlations with the liking of spicy foods, but not with non-spicy control foods. That specificity matters: it’s not about loving food in general, it’s about craving intensity.
Research indicates that elevated ratings of sensation-seeking among those from the United States were positively associated with the consumption and desire for spicy peppers. An affinity for spicy flavors correlates with heightened risk-taking behaviors, and laboratory research has shown that consuming spicy food can temporarily enhance the inclination to engage in risky activities.
The theory of benign masochism provides a possible explanation for why spicy consumption is related to risk-seeking tendencies. Benign masochism refers to the enjoyment derived from negative experiences that we initially perceive as threatening – such as eating peppers or riding roller coasters. Jalapeño fans, in other words, might genuinely enjoy the edge of discomfort.
Vegetables (Multiple Toppings): The Conscientious Idealist
Loading a pizza with spinach, peppers, onions, olives, and artichokes is a choice that tends to attract a particular kind of person. A study of over 1,000 young adults found that eating fruits and vegetables was related to greater openness, extraversion, and to a lesser extent, conscientiousness.
Higher openness to experience is related to a higher intake of vegetables and fruits, while higher neuroticism is related to unhealthier eating habits. Multi-vegetable pizza fans tend to score well on both counts: they’re curious about the world and reasonably disciplined about what goes into their bodies.
According to Dr. Hirsch’s research, those who prefer several vegetables are trustworthy, loyal, dependable, humble, and introverted, and tend to function best in a group environment. They’re the colleagues who quietly get things done, and the friends who actually show up when it counts.
Sausage: The Grounded Traditionalist
Sausage is a distant second to pepperoni in the national favorites ranking, with roughly one in eight Americans listing it as their top pizza topping. People who prefer sausage are often drawn to substance over style – they know what they like, and they don’t particularly want to be talked out of it.
People who want savory foods tend to be a bit serious and may have a dry sense of humor. Sausage lovers fit that profile: they’re not interested in novelty for its own sake, and they tend to view reliability as a genuine virtue rather than a limitation.
Researchers have noted that taste preferences develop at the same time as our personality, which is why food preferences are representative of our inner character. For sausage fans, that inner character tends to be one of consistency, warmth, and a healthy skepticism of food fads.
Anchovies: The Contrarian Individualist
Almost nobody orders anchovies, and the people who do know exactly what they’re getting into. The nation’s least favorite pizza topping is anchovies, with roughly three in ten Americans naming it their least favorite. Only about one percent name it as their favorite topping.
Research surveying hundreds of Americans found that preferences for bitter and intensely flavored food were associated with antisocial traits and were negatively correlated with agreeableness. Anchovy lovers have made peace with the fact that most people disagree with their choices – and that peace is telling.
There’s something quietly confident about choosing the topping with the most vocal opposition. Research in personality and food psychology has focused significantly on sensation seeking and openness to novel experiences, with these traits linked to a preference for strong, pungent, and bitter foods and drinks. The anchovy devotee usually scores high on both.
Bacon: The Optimistic Social Type
Bacon brings a particular energy to a pizza – smoky, slightly indulgent, undeniably crowd-pleasing. Men are notably more likely than women to order bacon as a pizza topping, with a significant gap observed across surveys. Younger consumers aged 18 to 24 also show a stronger preference for bacon compared to the national average.
A study in the Journal of Personality and Social Psychology found that those who enjoy sweet or indulgent-tasting foods tend to be more agreeable and compassionate than average. Bacon sits in that comfort-meets-boldness zone where agreeable, socially confident personalities tend to thrive.
Personality trait researchers have suggested that a greater preference for sweet and savory tastes is found in individuals with greater prosocial personality traits and higher levels of agreeableness. Bacon lovers tend to be the people who bring snacks to the meeting without being asked – a very specific kind of generosity.
Plain Cheese (No Toppings): The Focused Minimalist
There’s a version of simplicity that’s actually quite deliberate. Ordering plain cheese pizza isn’t always laziness – sometimes it’s precision. Research has connected picky eating habits to more anxious personalities, with a study of college students finding that more anxious individuals had a greater number of food aversions, potentially due to neuroticism and reduced emotional flexibility.
Picky eaters may also be supertasters – people who have more taste buds and thus experience flavors at a greater intensity. For these individuals, the “plain” pizza is anything but: they’re tasting every subtle layer of the sauce and cheese with more sensitivity than most.
Novelty-seeking has been linked to a preference for salty and adventurous foods, while anxious individuals appear to enjoy a much narrower range of foods overall. Plain cheese pizza fans often know themselves well: they’re not avoiding complexity out of ignorance, but because they’ve found exactly what they want and see no reason to complicate it.
What the Science Actually Says (and Doesn’t)
The evidence published to date supports a number of intriguing connections between personality traits and taste perception and food behavior. That said, the field is still young and has real limitations worth acknowledging. The reliability of existing research is limited by small sample sizes and inconsistent measurement tools.
Researchers have noted that taste preferences develop at the same time as our personality, which is why food preferences are representative of our inner character – though culture, upbringing, and repeated exposure all shape those preferences too. No single topping choice is deterministic.
Nuances exist that challenge overly simplistic interpretations. One may find themselves identifying as an adventurous eater while concurrently having a strong love for classic comfort foods. This duality may reveal a rich, complex individual who seeks both novelty and familiarity, illustrating that food preferences can be both diverse and dynamic.
Your pizza order is a small, honest data point about who you are – not a complete diagnosis. The real insight isn’t which topping you pick, but how willing you are to think seriously about why.
