WE HAVE ALWAYS PROCESSED OUR FOOD; this is an activity that is uniquely human. We cook our food—that is one type of processing–as well as ferment, grind, soak, chop and dry. All of these are types of food processing.
Traditional processing has two functions: to make food more digestible and to preserve it for use during times when food isn’t readily available. Nutritious, long-lasing processed foods including pemmican, hard sausage and old-fashioned meat puddings and haggis, as well as grain products, dairy products, pickles—everything from wine and spirits to lacto-fermented condiments. Farmers and artisans—bread makers, cheese makers, distillers, millers and so forth—processed the raw ingredients into delicious foods that retained their nutritional content over many months or even years, and kept the profits on the farm and in the farming communities where they belonged.
Unfortunately, in modern times, we have substituted local artisanal processing with factory and industrial processing, which actually diminishes the quality of the food, rather than making it more nutritious and digestible. Industrial processing depends upon sugar, white flour, processed and hydrogenated oils, synthetic food additives and vitamins, heat treatment and the extrusion of grains.
