Objectives:
To determine whether listening to a podcast about omega-3 fatty acids (n-3s) while grocery shopping increased shoppers' awareness about and purchases of seafood and other foods rich in n-3s.
Methods:
Repeated-measures design with a convenience sample (n = 56) of grocery shoppers who listened to the podcast while shopping. Pre- and postintervention semistructured interviews were conducted. The Theory of Reasoned Action was the study's framework.
Results:
Shoppers were primarily females (mean age, 41 ± 15.3 years). Their perceived ability to buy [t(55) = 6.27, P < .0001] and perceived importance regarding buying [t(55) = 3.38, P < .01] n-3-rich foods improved significantly. At least 1 n-3 rich food (mean, 1.5 ± 0.8) was purchased by 30%, and 79% planned future purchases.
Conclusion And Implications:
Podcasts may effectively communicate nutrition information. More research with a larger sample size is needed to evaluate the effects of the podcast on long-term changes in shopping behavior.
