Manufacturing EpidemicsThe Role of Global Producers in Increased Consumption of Unhealthy Commodities Including Processed Foods, Alcohol, and Tobacco

Let's start with a simple, unsettling idea: the things that make us sick aren't just cigarettes over here and soda over there. They're a family of products—ultra-processed foods, soft drinks, tobacco, and alcohol—built and pushed by the same global machinery. And that machinery is really good at what it does. Stuckler, McKee, Ebrahim, and Basu put it bluntly: these are manufactured epidemics. The striking twist is where they're growing. Not in the rich countries you might expect, but fastest in low- and middle-income countries, where budgets are tight, markets are opening, and companies see the future. Why stitch these products together? Because they move together. They share shelf-stable formulas, cheap inputs, and huge margins—on the order of a quarter of the retail price for items like soft drinks and tobacco. They travel on the same trade agreements, the same foreign direct investment pipelines, and the same ad campaigns. And when barriers fall, they flood in. That's the big frame. Now, how do we know? The team grounded their story in market sales, not self-reported diets. They tapped EuroMonitor's Passport database, which tracks per-capita sales of packaged foods, soft drinks, alcohol, and tobacco in up to eighty countries from 1997 to 2010, with forecasts to 2016. Think of it as a cash-register view of the food and beverage world. It's not perfect—sales aren't the same as intake; waste and informal markets get missed—but for comparing countries over time, these data are stable. To make apples-to-apples comparisons, they analyzed volumes and sales at constant 2011 prices and fixed exchange rates. They asked two questions. First, where is consumption rising fastest? Second, what's driving those increases? And they answered them with a population lens, channeling Geoffrey Rose's reminder that to understand why whole populations get sick, you look at the big forces—income, urbanization, and market integration—more than individual choices. On the "where" question, the pattern is hard to miss. Growth in snacks, soft drinks, and processed foods is fastest in low- and middle-income countries. In high-income countries, the curve has flattened out, with little or no growth projected over the following five years. Keep the tape rolling forward and you see convergence: if recent trajectories hold, low- and middle-income countries, or LMICs, could reach current high-income consumption levels for these foods within about three decades. And because LMIC populations are more than five times larger, most of the world's soft drinks, salty snacks, and ready meals are already being, and will continue to be, consumed there. Tobacco and alcohol follow the same road, just at a slower speed. In LMICs, they were projected to rise by roughly twenty percent over five years, with about four decades to catch up to then-current rich-country levels, while many rich countries were inching down, helped along by the post-2008 recession. Zoom in and you see the market footprints that make this possible. Multinationals are everywhere. In Brazil, Nestlé holds about eight point four percent of the packaged-food market—an eye-catching single-firm share for a sprawling sector. In Mexico, PepsiCo and Nestlé are at five point three and three point eight percent, respectively, both sitting near the top. Across LMICs, at least one multinational was among the top two manufacturers in every country they analyzed, with China the big exception. In the United States, the familiar giants—Kraft, PepsiCo, and Nestlé—sit on top too, but the striking thing is how similar the competitive picture has become across income levels. It's not a local bodega story. It's a global distribution and branding story. Now, if you track the products over time, some countries jump off the page. Vietnam and India were on track to double soft drink consumption per person. Egypt, China, Tunisia, Cameroon, and Morocco were set to grow by about fifty percent in soft drinks or processed foods, in some cases posting double-digit increases year after year. And then there's Mexico, the outlier: more than three hundred liters of soft drinks per person annually and one of the highest child obesity rates in the developing world—over thirty percent. For its level of income, that's off the curve. It tells you that policy and market structure can bend the line. Here's a deeper clue: when the authors linked the markets together, they found a tight bundle. Countries that were high in tobacco and alcohol sales also tended to be high in soft drinks and processed foods. Across eighty countries in 2010, the correlation among these four categories was about zero point seventy-nine—very strong—while staples like oils and fats didn't move with the pack at all. That's important. It suggests the driver isn't just "more money, more calories." It's the shared regulatory and marketing environment. And yes, rising income matters too. In the cross-sections, gross domestic product, or GDP, per capita was moderately to strongly associated with soft drinks, snacks, and processed foods—soft drinks around zero point fifty-nine, snacks closer to zero point seventy-one. But the story gets more interesting when you add the role of global capital. On the "why" question, two forces stand out: income and market integration. The authors built a set of panel models for fifty LMICs, using World Bank indicators to track GDP per capita, the share of the population living in cities, and foreign direct investment, or FDI, as a share of GDP. Methodologically this is pretty standard, but solid: multiple categories, robust clustered errors to account for repeated country observations, outcomes measured in per-capita volumes or sales. The results? Rising income is consistently associated with higher per-capita sales across almost all categories—alcohol, tobacco, packaged foods, processed foods, soft drinks, confections, and ice cream. The models aren't explaining everything, but they explain a lot, with R squared values ranging from roughly zero point twenty-two up to about zero point fifty-one depending on the category, strongest for processed foods and soft drinks. Urbanization surprised them. The old story says "more cities, more fast food." Here, once you control for income and integration, urbanization mostly drops out. The exception is soft drinks, where urban living still carries some weight. The heavyweight variable turns out to be FDI. Where foreign direct investment is higher—think bottling plants, distribution hubs, big-box retail—exposure to soft drinks, processed foods, and alcohol is higher, full stop. And FDI doesn't just add its own effect; it changes what income does. When FDI is under about two percent of GDP, the link between rising GDP and more consumption essentially disappears for things like confections, ice cream, processed foods, packaged foods, even tobacco. When FDI is above that threshold, the GDP-consumption link switches on and strengthens, especially for soft drinks. Put plainly: money only turns into market penetration when there's a pipeline to pour products through. Trade policy shows up the same way. In countries with free-trade agreements with the United States, per-capita soft drink consumption sits about sixty-three percent higher than in comparable countries without those agreements, even after adjusting for income and urbanization. The confidence interval is wide—roughly twenty-four to one hundred three percent—but the direction is clear. If you open the door wide for beverages, beverages walk in. If you want proof that rules matter, look at the policy case studies they sketch. After Mexico opened its market through a U.S. trade deal in the nineteen nineties, soft drink sales surged alongside a visible wave of multinational entry. Venezuela, without that agreement, saw steadier consumption despite economic growth. Tobacco shows the mirror image: Brazil's late nineteen nineties push—price hikes, public bans, strong controls even before the global Framework Convention on Tobacco Control—coincided with a sharp fall in tobacco consumption, on the order of a seventy-five percent drop between nineteen ninety-eight and two thousand three, and low levels thereafter. Chile, which implemented strict tobacco controls later, experienced rising use in the interim. And in high-income Europe, the United Kingdom's deregulated retail landscape—cheaper alcohol in giant supermarkets, easier access—has coincided with higher per-capita alcohol consumption than France by roughly thirty percent. Same population? No. Same products? Largely. Different rules? Definitely. One more link ties this market story back to health. Where countries consume more of these unhealthy commodities, obesity and diabetes rates tend to be higher. The paper is careful here: these are population-level associations, not a clean causal arrow. Still, obesity shows up as a leading indicator of exposure to this cluster of products, which is exactly what you'd expect if environments are shifting. Let's be honest about the limitations. Sales volumes aren't bites and sips. They miss what's wasted, what's homemade, and what's smuggled. Informal stalls and nonretail channels are undercounted. Forecasts are forecasts. But the consistency of the cross-country patterns, the convergence by income level, the strength of the clustering, and the way FDI and trade crack open markets—all of that hangs together. So what do we do with this? The lesson from tobacco still applies: prices and availability matter enormously. Raising prices through taxes, limiting access through licensing and retail rules—these are blunt tools, but they're effective and cheap. In settings where supermarkets and beverage aisles have raced ahead of regulation, dialing back the ease and ubiquity of purchase can slow the curve. Trade and investment rules are less visible but just as powerful. As Stuckler and colleagues point out, how you design a trade agreement shows up later in what's on the shelf and what people drink. That sixty-three percent bump tied to U.S. agreements isn't a footnote; it's a nutrition policy hiding in a commerce document. Market power matters too. When a handful of firms control large shares of shelf space, their promotions and pricing shape what's "normal." The authors call for better surveillance of concentration—who owns how much of the retail floor—as well as stronger conflict-of-interest rules so health policy isn't captured by the companies it's supposed to constrain. And they argue for marketing restrictions and availability limits that focus where vulnerability is highest, including urban-poor neighborhoods where cheap calories crowd out healthier staples. Underneath all this is that paradox we started with. Poverty can raise risk, not because people suddenly crave soda, but because cheap, aggressively marketed products meet loosened rules and rising distribution capacity. Wealth growth without guardrails doesn't automatically deliver healthier diets; it delivers whatever the most profitable supply chain can sell. If you're a data person, you may be itching for more. So are the authors. They want finer-grained measures of retail-sector foreign direct investment, the guts of trade agreements—tariffs, quotas, non-tariff barriers—better tracking of market concentration, and better data on the availability and price of healthier alternatives. Those aren't academic wish lists; they're the instruments that would let us tell whether policy is working and where the next push will come from. Let me end on a sober optimism. None of this is destiny. The same levers that sped these products into low- and middle-income countries—investment rules, trade terms, taxes, placement, promotion—can be pulled in the other direction. Brazil's tobacco turnaround shows it. So does the softening of alcohol use where pricing and access have tightened. The global food system is complex, but it isn't a black box. It's a set of incentives and channels. And as Stuckler and colleagues remind us, if we want different outcomes, we need to change the channels through which money becomes markets, and markets become meals.
