Bread has been a staple in the human diet for thousands of years. But for the last few decades, modern diets have villainized the baked good. According to Nielsen, total bread sales in the United States have been stagnant since 2015, showing little to no growth leading up to 2020. But bread is making a comeback, specifically sourdough bread. Sales of sourdough bread grew about 11.6 percent from 2015 to 2019 to over $325.9 million.
