Michael Pollan on our broken food system



...The food chain is buckling. But it’s worth pointing out that there are parts of it that are adapting and doing relatively well. Local food systems have proved surprisingly resilient. Small, diversified farmers who supply restaurants have had an easier time finding new markets; the popularity of community-supported agriculture (CSA) is taking off, as people who are cooking at home sign up for weekly boxes of produce from regional growers. (The renaissance of home cooking, and baking, is one of the happier consequences of the lockdown, good news both for our health and for farmers who grow actual food, as opposed to commodities like corn and soy.) In many places, farmer’s markets have quickly adjusted to pandemic conditions, instituting social-distancing rules and touchless payment systems. The advantages of local food systems have never been more obvious, and their rapid growth during the past two decades has at least partly insulated many communities from the shocks to the broader food economy.

The pandemic is, willy-nilly, making the case for deindustrializing and decentralizing the American food system, breaking up the meat oligopoly, ensuring that food workers have sick pay and access to health care, and pursuing policies that would sacrifice some degree of efficiency in favor of much greater resilience. Somewhat less obviously, the pandemic is making the case not only for a different food system but for a radically different diet as well.

It’s long been understood that an industrial food system built upon a foundation of commodity crops like corn and soybeans leads to a diet dominated by meat and highly processed food. Most of what we grow in this country is not food exactly, but rather feed for animals and the building blocks from which fast food, snacks, soda, and all the other wonders of food processing, such as high-fructose corn syrup, are manufactured. While some sectors of agriculture are struggling during the pandemic, we can expect the corn and soybean crop to escape more or less unscathed. That’s because it takes remarkably little labor—typically a single farmer on a tractor, working alone—to plant and harvest thousands of acres of these crops. So processed foods should be the last kind to disappear from supermarket shelves.

Unfortunately, a diet dominated by such foods (as well as lots of meat and little in the way of vegetables or fruit—the so-called Western diet) predisposes us to obesity and chronic diseases such as hypertension and type-2 diabetes. These “underlying conditions” happen to be among the strongest predictors that an individual infected with Covid-19 will end up in the hospital with a severe case of the disease; the Centers for Disease Control and Prevention have reported that 49 percent of the people hospitalized for Covid-19 had preexisting hypertension, 48 percent were obese, and 28 percent had diabetes.9

Why these particular conditions should worsen Covid-19 infections might be explained by the fact that all three are symptoms of chronic inflammation, which is a disorder of the body’s immune system. (The Western diet is by itself inflammatory.) One way that Covid-19 kills is by sending the victim’s immune system into hyperdrive, igniting a “cytokine storm” that eventually destroys the lungs and other organs. A new Chinese study conducted in hospitals in Wuhan found that elevated levels of C-reactive protein, a standard marker of inflammation that has been linked to poor diet, “correlated with disease severity and tended to be a good predictor of adverse outcomes.”10

Amomentous question awaits us on the far side of the current crisis: Are we willing to address the many vulnerabilities that the novel coronavirus has so dramatically exposed? It’s not hard to imagine a coherent and powerful new politics organized around precisely that principle. It would address the mistreatment of essential workers and gaping holes in the social safety net, including access to health care and sick leave—which we now understand, if we didn’t before, would be a benefit to all of us. It would treat public health as a matter of national security, giving it the kind of resources that threats to national security warrant.

But to be comprehensive, this post-pandemic politics would also need to confront the glaring deficiencies of a food system that has grown so concentrated that it is exquisitely vulnerable to the risks and disruptions now facing us. In addition to protecting the men and women we depend on to feed us, it would also seek to reorganize our agricultural policies to promote health rather than mere production, by paying attention to the quality as well as the quantity of the calories it produces. For even when our food system is functioning “normally,” reliably supplying the supermarket shelves and drive-thrus with cheap and abundant calories, it is killing us—slowly in normal times, swiftly in times like these. The food system we have is not the result of the free market. (There hasn’t been a free market in food since at least the Great Depression.) No, our food system is the product of agricultural and antitrust policies—political choices—that, as has suddenly become plain, stand in urgent need of reform.
