The version of ‘wheat’ we consume today is a product of genetic research

For all the high-tech gadgets on display in the Bread Lab, the operation is decidedly old-fashioned, relying on stone mills of a type that have not been used for more than a century and on a philosophy that all it takes to make genuine and delicious whole-wheat bread is time, talent, flour, a little salt, and lots of water. There are essentially two ways to turn flour into bread. The first is the way it was done for most of human history: let the flour absorb as much water as possible and give it time to ferment, a process that allows yeast and bacteria to activate the dough. Kneading then binds the two proteins that come together to form gluten. Most of the bread consumed in the United States is made the other way: in place of hydration, fermentation, and kneading, manufacturers save time by relying on artificial additives and huge industrial mixers to ram together the essential proteins that form gluten.

Until the late nineteenth century, when steel rollers and industrial mills came into use, wheat was ground on stones, a slow and imprecise process. Steel was fast, efficient, and easy to maintain, and it permitted millers to discard the germ and the bran in the wheat kernel and then rapidly process the starchy endosperm. This made white flour. Almost nobody seemed to notice, or care, that by tossing out the rest of the kernel industrial bakers were stripping bread of its vitamins, its fibre, and most of its healthy fats. White bread was seen as an affordable luxury. Like many Jews arriving from Russia at the turn of the twentieth century, my great-grandfather had never seen white bread before, but when he did he immediately made what was referred to, at least in my family, as an “American sandwich”: he took two pieces of the black bread that he had always eaten, and carefully placed a piece of industrially made white bread between them. He is said to have been delighted.

Some researchers argue that wheat genes have become toxic. Davis has said that bread today is nothing like the bread found on tables just fifty years ago: “What’s changed is that wheat’s adverse effects on human health have been amplified many-fold. . . .The version of ‘wheat’ we consume today is a product of genetic research. . . . You and I cannot, to any degree, obtain the forms of wheat that were grown fifty years ago, let alone one hundred, one thousand, or ten thousand years ago. . . . We have to restrict other carbohydrates beyond wheat, but wheat still stands apart as the worst of the worst.’’

William Davis, a cardiologist whose book “Wheat Belly” created an empire founded on the conviction that gluten is a poison, the protein has become a culinary villain. Davis believes that even “healthy” whole grains are destructive, and he has blamed gluten for everything from arthritis and asthma to multiple sclerosis and schizophrenia. David Perlmutter, a neurologist and the author of another of the gluten-free movement’s foundational texts, “Grain Brain: The Surprising Truth About Wheat, Carbs, and Sugar—Your Brain’s Silent Killers,” goes further still. Gluten sensitivity, he writes, “represents one of the greatest and most under-recognized health threats to humanity.’’
