The contextual effect of the local food environment on residents' diets: the atherosclerosis risk in communities study.
OBJECTIVE
We studied the association between the local food environment and residents' report of recommended dietary intake.


METHODS
Recommended intakes of foods and nutrients for 10 623 Atherosclerosis Risk in Communities participants were estimated from food frequency questionnaires. Supermarkets, grocery stores, and full-service and fast-food restaurants were geocoded to census tracts.


RESULTS
Black Americans' fruit and vegetable intake increased by 32% for each additional supermarket in the census tract (relative risk [RR] = 1.32; 95% confidence interval [CI] = 1.08, 1.60). White Americans' fruit and vegetable intake increased by 11% with the presence of 1 or more supermarket (RR = 1.11; 95% CI = 0.93, 1.32).


CONCLUSIONS
These findings suggest the local food environment is associated with residents' recommended diets.
