Racial/Ethnic Discrimination and Food Consumption: Examination in Diverse Samples.

Experiencing racial discrimination may undermine health through effects on health behavior, including patterns of food consumption. In two studies, we tested whether racial discrimination was linked with food consumption, specifically the frequency with which people ate healthy and unhealthy foods. We investigated both lifetime exposure to discrimination as well as more recent (past-week) exposure as predictors of food consumption. Study 1 focused on racially and ethnically diverse adults from New York City (NYC); Study 2 focused on American Indian and Alaska Native (AI/AN) adults from the Denver metro area. Overall, we found that higher levels of discrimination were associated with more frequent consumption of both unhealthy and healthy food. The timing of discrimination mattered. Higher levels of discrimination within the past-week were associated with more frequent consumption of healthy and unhealthy foods. In contrast, higher levels of lifetime discrimination were associated only with more frequent consumption of unhealthy food. The links between discrimination and food consumption remained significant controlling for socioeconomic status. The relations of discrimination to food consumption were similar across the diverse sample from NYC and the AI/AN sample from Denver. These findings may help researchers understand how discrimination may contribute to health disparities.
