High in the hills south of Santa Fe, New Mexico, stands a greenhouse that Luke Reed hopes will help American Indians eat healthier. Reed also recently used the structure, completed in August, to teach a course on greenhouse management to representatives of the nearby Santo Domingo, Cochiti and Santa Clara pueblos. Near the greenhouse, fruit trees and a community garden that grows lettuce, spinach, broccoli and cauliflower have also provided fare for the school cafeteria--as well as lessons in raising healthy food. Many of the 37 tribal colleges are making some sort of effort to promote "food sovereignty," a term that has come to mean ensuring American Indians access to and control over affordable, high-quality food. The colleges, a multitude of agencies and community groups and the tribes themselves are part of a movement to help American Indians eat healthier.
