As of April 29, 2020, the WHO declared that “most people consume too much salt—on average….twice the recommended maximum levels of intake,” and laid out guidelines for reducing salt intake. Increasing consumption of processed foods has gone hand in hand with the growth of cities, leading people to consume more salt, saturated fats, and sugars and less fresh fruits and vegetables. Fresh food has always been one of the limiting factors for urban areas, but the modern solution of introducing heavily processed and preserved foods has introduced new health complications.
This was not always the case. Ancient cities, for instance, often relied on imported grain that could be transported long distances without spoiling. In these cases, getting enough salt was a significant concern. Before the advent of reliable refrigeration, though, food preservation required salt, which, in turn led to labor-intensive operations to evaporate salt from the seas in order to fuel the production of fermented and aged foods, and for adding directly to fish like cod in order to preserve them for future consumption.
In Salt, Mark Kurlansky evaluates the production of salt in a global context, aiming in the process to offer a history of the world as defined by this one commodity. He is partially successful and offers a portrait of food production around the world with a wealth of details.
Individual episodes of this story were fascinating. For instance, I was struck by the lengths taken to ensure salt production, including elaborate brining pools to encourage evaporation of sea water and exceedingly deep mines in China to extract rock salt. Likewise, the discussion of individual foods like cod and hams, products that were largely made possible by the widespread availability of salt, were right up my gastronomic alley.
And yet, I was often frustrated by Salt. The problem is in Kurlansky’s attempt to weave the history of salt through the history of the world. Sections where he dug into the history of the industry worked exceedingly well, but other sections examined historical events like the French Revolution in such a way that it blew the importance of salt out of proportion. In the chapter on the American Civil War, for instance, he alternated between a fascinating discussion of Avery Island, the birthplace of Tabasco Sauce, and accounts of the US Navy destroying southern saltworks. The former was great, the latter I thought less enlightening in that it offered only a partial portrait of the war while also adding only marginally to the story of the mineral.
However, the biggest problem I had with Salt is that it is a book rich in detail and light in narrative through-line.In a highly technical book this lack of narrative would be less of an issue, but here I found the lack to make sections of the book rather slow going one chapter didn’t neatly lead to the next in any way except that they both explored aspects of the salt industry. Kurlansky’s overarching thesis is that salt was really important in world history, which is hard to deny, but also doesn’t offer a clear way forward to carry out that argument (as I might tell my students). I might go back to Salt to season some of my history classes, but as a commodity history its broad scope and argument were not to my taste.
In addition to the backlog of books I haven’t written about (yet), I recently finished Robert Massie’s Dreadnought, after which I am now in the market for a book that actually talks about the development of the British Navy from the end of the Napoleonic Wars through at least World War One since my go-to historian on the topic, N.A.M. Rodgers, evidently never published the third volume of his history of the British Navy. I am now reading Maja Novak’s The Feline Plague, a magical-realism novel about Slovenia’s transition from communism to capitalism in the early 1990s.
