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.
