Why do some foods become global sensations while others vanish without a trace? In his book “Nutrition in Transition,” food trend researcher Michael Ballarini explores the mechanisms behind our ever-evolving dietary preferences. From sushi’s rise to stardom to the mystery of avocado mania, Ballarini’s work unveils a fascinating system behind what ends up on our plates. This feature introduces his methodology, highlights key trends, and provides readers with a clear framework for spotting the next big food wave.
The Invisible Logic Behind Every Bite
What Michael Ballarini manages brilliantly in Nutrition in Transition is to break through the chaos of food trends and deliver a system—a structure—that reveals how our diets evolve. While the food media often hypes the next kale or quinoa without substance, Ballarini demands rigor: asking why a trend emerges, who promotes it, and whether it’s here to stay. The results? A compelling theory that blends behavioral economics, sociology, and culinary history.
The Dietary Profile is the backbone of his methodology. Imagine a map of a culture’s collective food choices, shaped by what’s available, what’s accepted, and what aligns with people’s values. Ballarini shows how these profiles vary not only by region but across time. For example, he walks us through how sushi, once feared and foreign, became a lifestyle staple—a story not of taste alone, but of cultural acceptance and strategic multiplication.
But more than that, Ballarini elevates the discussion of food to something sociological, almost anthropological. Food is not just sustenance—it’s identity, memory, status, ideology. That’s why trends are not just superficial fads. They are expressions of collective values in flux.
From Dare to Daily: The Sushi Case Study
Sushi’s evolution is one of the book’s most compelling examples. Originally a preservation method in Southeast Asia, it transformed into a refined cuisine in Japan and, over decades, entered Western markets. But its road to becoming a global lunch menu item wasn’t linear.
Michael Ballarini highlights key forces: Japanese-American migration, political shifts post-WWII, and—crucially—multipliers like celebrity endorsements, high-end restaurants, and health narratives. Slowly, sushi gained both acceptance width (more people tried it) and depth (they talked about it, shared it, posted about it). It became more than food; it became status, identity, and lifestyle.
His insight? Trends that move from niche to mass have both emotional appeal and structural support. Without this, even delicious foods disappear. Think of Vietnamese pho—it’s beloved by many, but has not yet reached the same global entrenchment as sushi. Why? Because the multipliers and acceptance width are not as coordinated. A delicious dish is not enough. Timing, media, migration, even health narratives must align.
Understanding the Engine: Acceptance Width & Depth
Ballarini introduces a groundbreaking dual-axis model:
- Acceptance Width = how many people consume a food or concept.
- Acceptance Depth = how committed those consumers are (e.g., sharing, cooking, advocating).

Using this grid, he identifies five trend zones—from obscure loves to viral hypes. For instance, offal (organ meats) once had high depth but low width—a chef’s darling but a consumer’s nightmare. Through campaigns and sustainability narratives, it gained traction, nudging toward the trend zone.
Another example: palm oil. Widely consumed (high width) but with shallow emotional investment (low depth). Once controversies surfaced, consumers quickly rejected it. Ballarini uses this to illustrate how trends can vanish just as fast as they rise.
From my own experience, I’d add the case of “activated charcoal.” It flooded Instagram feeds in everything from ice cream to lemonade. But it lacked depth. Once questions about its health benefits emerged, it disappeared. A classic example of a trend stuck in the hype phase, with no structural foundation.
Events That Shift the Plate
Ballarini doesn’t ignore chaos. He dedicates a chapter to unforeseen shocks—events that radically change food behavior. The BSE crisis in the early 2000s, for example, tanked beef sales and made transparency in meat production a mainstream concern. The COVID-19 pandemic did the same for supply chains and local foods.
These “black swan” events, though rare, force trend acceleration or destruction. In forecasting food trends, Ballarini insists we must account for the unpredictable.
We saw a similar shift in consumer behavior with the Ukraine war. The resulting sunflower oil shortages forced many restaurants to rethink frying practices, pushing demand for alternative oils and even influencing home cooking patterns. These reactions, while reactive, become long-term habits if they align with consumer values.
How to Read the Future of Food
One of the book’s most practical aspects is its application. Ballarini offers tools to assess trend likelihoods. He shows how dietary targets (like health or sustainability) influence concepts (like veganism or Mediterranean diets), which in turn affect specific food choices (like oat milk or quinoa bowls).
Importantly, Michael Ballarini challenges lazy trend reporting. For him, a food becomes a trend only when it enters both cultural dialogue and personal habits. It’s not enough for avocado toast to flood Instagram—it needs to shape supermarket shelves and home kitchens.
To understand the mechanics better, Ballarini asks readers to assess how deep a trend’s roots are: Does it reflect a larger value system? Is it scalable? Are multipliers aligned? These questions can be applied to anything—mushroom coffee, zero-waste snacks, or even lab-grown meats.
Real-Life Examples That Stick
- Avocado: Once an exotic fruit, it became symbolic of wellness, wealth, and now even climate debate. The shift to local sourcing (e.g., in Spain or Israel) removed the sustainability stigma, widening its appeal. The rise of avocado toast was a visible symptom of a larger trend.
- Sushi: A trend built on slow cultural integration, logistical improvements, and identity marketing. It went from a dare to a weekday lunch thanks to silent persistence and smart multiplication.
- Offal/Nose-to-Tail: A sustainability-led revival driven by chefs and media, showing how even stigmatized foods can trend. In a time where waste reduction is key, this movement is moral and culinary.
- Soy: Once dominant in the plant-based world, soy is facing backlash due to health and environmental concerns. Oat milk, almond, and pea protein have stepped in. Trend fatigue is real.
- Toast Hawaii: A historical example of how exotic ingredients (pineapple, ham) create novel dishes. But its decline also shows how fast tastes and aesthetics shift.
The Multipliers: More Than Just Influencers
Michael Ballarini coins the term “multipliers” to describe those who help dietary preferences gain traction. These can be:
- Influencers and chefs
- Media outlets
- Supermarkets (through shelf placement)
- Governments and health institutions
A trend’s success is often tied to how many multipliers are aligned. Think of turmeric lattes. Their rise involved health blogs, vegan cafes, science articles on anti-inflammation, and golden-hued Instagram posts. It was a perfect storm.
Compare that to black garlic. Delicious, intriguing, but without consistent multiplier support. Still a niche item.
More Than Food: Identity and Values
What makes Ballarini’s book valuable is how it connects food to identity. People don’t just consume; they express. A Gen Z student buying vegan nuggets is making a statement. A millennial sipping mushroom coffee feels ahead of the curve. A boomer returning to sourdough bread post-lockdown is finding comfort in tradition.
Food is emotional. That’s why Ballarini’s acceptance depth is so crucial. If we understand not just how many people eat something, but how much they care about it, we understand the emotional velocity of a trend.
As someone who’s worked with restaurant brands, I’ve seen trends rise and fall because of emotional tone-deafness. A menu item might be brilliant, but if it doesn’t feel aligned with the diner’s identity, it flops. Ballarini provides a much-needed framework to navigate this landscape.
From the Book to the Boardroom
The implications of Ballarini’s work go beyond theory:
- Restaurateurs can use the dietary profile to test concepts with the right emotional alignment.
- Product developers can identify underexploited trends with high potential.
- Marketers can avoid wasting budget on shallow hypes.
- Policymakers can promote healthier, more sustainable eating with greater cultural insight.
The key is not to follow fads, but to understand the structural forces behind them. This is where Ballarini shines. He brings method to madness.
Analysis & Outlook
Michael Ballarini’s Nutrition in Transition marks a new chapter in how we understand and analyze food trends. As the food world becomes more complex, his system offers clarity.
His framework is especially relevant now. We live in a time of:
- Cultural fragmentation
- Identity-driven consumption
- Rapid innovation in food tech
- Climate-conscious eating
In such a context, it’s no longer enough to spot a trend. We must evaluate it. Is it driven by real need or just novelty? Is it scalable? Does it align with core dietary targets?
Expect to see more professionals adopt Ballarini’s approach. It’s rigorous, replicable, and flexible. From hospitality to retail to food media, his impact is only beginning.
