First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested whether eating almonds every day can improve the immune system's response to the flu vaccine in overweight middle-aged men and postmenopausal women. Participants either added almonds as a snack or avoided them for several weeks. Researchers measured immune cell activity and tracked respiratory infections to see if almonds made a difference.
