The objective of this research was to determine serum carotenoid concentrations and fruit, vegetable, and carotenoid intake among participants in the Northeast Georgia Elderly Nutrition Program (ENP). Intake was estimated by the Behavioral Risk Factor Surveillance System Questionnaire (BRFSS) and the Block Food Frequency Questionnaire (FFQ). Participants were a convenience sample who attended senior centers where lunch was provided (n = 71; mean age = 76; 85.5% female; 65% white; 35% black). When compared to non-participants, participants were similar in age, gender and race. 25-33% of the participants ate 5 or more servings of fruit and vegetables daily. Only 24% of the participants knew that people should eat 5 or more fruit and vegetables daily. Serum carotenoids were more highly correlated with the Block FFQ than the BFRSS Questionnaire measure of fruit and vegetable intake, thus the Block FFQ may be better for this population.
