Sourdough Bread

"It's healthier than whole wheat," says Beller. Shocking, we know, but here's why: sourdough is unique because it's made with a lactic acid starter that undergoes fermentation, which alters the bread's starches.

"This helps prevent your blood sugar from spiking better than white or wheat bread," she says.

On a recent dinner out, a basket of homemade sourdough bread arrived at Beller's table. She didn't go to town on it (it's still bread, after all), but she took a half of a slice and enjoyed each bite.
