Abstract ABSTRACT-A hospital-based case-control study of gastric can-cer precursor lesions was conducted in a high-risk black popula-tion in southern Louisiana. Ninety-three SUbjects with biopsy-proved advanced chronic atrophic gastritis were compared to two control series: a gastroscopy clinic series and a general hospital-admission series. Dietary case-control differences indicated a pro-tective effect associated with fruit and vegetable intake and with dietary vitamin C and a risk elevation associated with milk con-sumption. The protective effect associated with consumption of fruits, vegetables, and vitamin C is consistent with findings for gastric cancer and with the etiologic hypothesis of intragastric nitrosation. A twofold increased risk was associated with cigarette smoking. Gastric juice pH, NOs-, and N02- were determined for subjects undergoing gastroscopy, and comparisons were made between this high-risk U.S. group and a Colombian population
