The Cod. Wars have been fought over it, revolutions have been triggered by it, national diets have been based on it, economies and livelihoods have depended on it. To the millions it has sustained, it has been a treasure more precious that gold. This book spans 1,000 years and four continents. From the Vikings to Clarence Birdseye, Mark Kurlansky introduces the explorers, merchants, writers, chefs and fisherman, whose lives have been interwoven with this prolific fish. He chronicles the cod wars of the 16th and 20th centuries. He blends in recipes and lore from the Middle Ages to the present. In a story that brings world history and human passions into captivating focus, he shows how the most profitable fish in history is today faced with extinction.
I think that I would put those books under the broad heading of social histories, which is a genre. You may also look for "microhistories", and here's a list of them:
Every person (back then) could observe farm animals had sex. Since no one had seen fish having sex, it was believed that fish spawned spontaneously from rivers/lakes/oceans and therefore were free from the animal version of "original sin". That's why so much effort was put into catching and preserving fish.

The author has a fascination with Basques & Basque history. Or maybe they really had a large influence in fishing and trans-Atlantic navigation. And that maybe they discovered the huge cod banks by Newfoundland before John Cabot did.

Medieval people were not stupid. They observed that pickled vegetables preserved the veggies for months. And they observed that people who ate pickled vegetables got scurvy (vitamin C deficiency disease) at a much lower rate. The recipes didn't travel too far, so while sauerkraut and kimchi are both pickled cabbage, with different spices they are wildly different.
