Flour is hard to sidestep come mealtime. Breakfast brims with toast, bagels, cereal, pancakes. Lunch is built around sandwiches, wraps, pasta, pizza. And dinner may come with its very own breadbasket.
Flours are produced by crushing grains into fine powders. And those powders form the basis not just for breads and buns, but for a huge variety of processed foods, from cereals, crackers and pizza dough to cookies, cakes and ice cream cones. As a result, the average American now eats 10 servings of refined grains each day.
As our national appetite for flour has inched up, so has the incidence of diet-related ills, such as obesity, heart disease and diabetes. Coincidence? Many nutrition experts don’t think so. When they weigh the evidence linking food choices and disease, they see the white, dusty fingerprints of flour everywhere.
“Now that trans fats are largely out of the food supply,” says David Ludwig, MD, PhD, director of the New Balance Foundation Obesity Prevention Center at Children’s Hospital Boston, “refined carbohydrates, including refined grain products, are the single most harmful influence in the American diet today.”
Flour started out as an ingenious fix to a vexing problem. Grass seeds were plentiful, but the tough outer shell (the husk) made the seeds difficult to chew and digest. Early humans outsmarted the seeds by grinding them between stones, crushing the outer layers to get at the goodness inside. The result — a coarse powder — was the first whole-grain flour.
The downside was spoilage. Crushing the germ released its oils, which quickly turned rancid when exposed to air. With the advent of industrial milling in the late 1800s, machines began filtering out the germ and pulverized the remaining endosperm into a fine, white powder that lasted on the shelf for months. And so all-purpose white flour was born — along with a host of health problems.
Beneath their rigid architecture, whole-kernel grains conceal an array of vitamins, minerals, phytonutrients and fiber. But when machines pulverize kernels into flour, even whole-grain flour, what’s left behind is a starchy powder capable of wreaking havoc on the body.
