A fantastic article that I keep returning to:

For our ancestors, natural was something quite nasty. Natural often tasted bad. Fresh meat was rank and tough, fresh fruits inedibly sour, fresh vegetables bitter. Natural was unreliable. Fresh milk soured; eggs went rotten. Everywhere seasons of plenty were followed by seasons of hunger. Natural was also usually indigestible. Grains, which supplied 50 to 90 percent of the calories in most societies, have to be threshed, ground, and cooked to make them edible.

So to make food tasty, safe, digestible, and healthy, our forebears bred, ground, soaked, leached, curdled, fermented, and cooked naturally occurring plants and animals until they were literally beaten into submission. They created sweet oranges and juicy apples and non-bitter legumes, happily abandoning their more natural but less tasty ancestors. They built granaries, dried their meat and their fruit, salted and smoked their fish, curdled and fermented their dairy products, and cheerfully used additives and preservatives–sugar, salt, oil, vinegar, lye–to make edible foodstuffs.

Eating fresh, natural food was regarded with suspicion verging on horror; only the uncivilized, the poor, and the starving resorted to it. When the ancient Greeks took it as a sign of bad times if people were driven to eat greens and root vegetables, they were rehearsing common wisdom. Happiness was not a verdant Garden of Eden abounding in fresh fruits, but a securely locked storehouse jammed with preserved, processed foods.

And get this:

The dishes we call ethnic and assume to be of peasant origin were invented for the urban, or at least urbane, aristocrats who collected the surplus. This is as true of the lasagna of northern Italy as it is of the chicken korma of Mughal Delhi, the moo shu pork of imperial China, and the pilafs, stuffed vegetables, and baklava of the great Ottoman palace in Istanbul. Cities have always enjoyed the best food and have invariably been the focal points of culinary innovation.

Nor are most “traditional foods” very old. For every prized dish that goes back 2,000 years, a dozen have been invented in the last 200. The French baguette? A 20th-century phenomenon, adopted nationwide only after World War II. Greek moussaka?  Created in the early 20th century in an attempt to Frenchify Greek food. Tequila?  Promoted as the national drink of Mexico during the 1930s by the Mexican film industry. These are indisputable facts of history, though if you point them out you will be met with stares of disbelief.

The whole thing is really excellent, just read it.
