Evidence suggests that good nutrition may help to maintain brain health. Little is known about attitudes about nutrition and brain health among older adults. Fifty focus groups with 436 older participants were conducted in 9 states. Core questions from a standard guide were used in all locations. Participants also completed a 9‐item survey. Using grounded theory and constant comparison methods, transcripts were independently coded and analyzed for themes, issues, and beliefs. Participants reported limiting fat intake, and eating at least as many fruits and vegetables as other people they know. Participants reported hearing or seeing media messages about diet, especially dietary supplements. However, when asked, “How can we keep our brains healthy?” participants rarely mentioned a good diet. Participants emphasized that environmental barriers to good nutrition were common. Older Americans are interested in brain health. They are uncertain about their ability to follow recommended health behaviors. Public health messages should address the fact most participants did not associate nutrition with healthy aging.
