THE NAVAJO NATION — When Summer Brown lived in Phoenix, she had no problem finding fresh produce. If the Sprouts supermarket near her home didn’t have what she was looking for, she would just drive somewhere else.
This winter, Ms. Brown, an enrolled member of the Navajo Nation, moved back to her childhood home in Cornfields, Ariz., to start a small business as a leatherworker. Now, healthy food is harder to find for her two children, Paisley, 6, and Landon, 7. The entire Nation, which stretches 27,000 square miles across Arizona, New Mexico and Utah, has fewer than 15 grocery stores.
