Blueberry Trial Summary
This trial tests if almonds can boost immune system in overweight older adults to fight flu better.
Who is the study for?
This trial is for overweight older men and postmenopausal women aged 50-70 who agree to get a flu shot. They must have a BMI of 25-32, be able to travel to Loma Linda University, and not be on immune-affecting meds or supplements. Those regularly eating berries, on immune boosters, recently on antibiotics or steroids, allergic to blueberries, vaccinated for flu within the last 10 months, or with uncontrolled diseases can't join.Check my eligibility
What is being tested?
The study is testing if blueberry powder affects immunity and how well participants respond to the flu vaccine compared to a placebo group. Participants will receive either the blueberry powder or a placebo without knowing which one they are getting.See study design
What are the potential side effects?
Since this trial involves consuming blueberry powder or a placebo equivalent, side effects may include potential digestive discomfort. However, as it's food-based rather than medication-related intervention being tested here; significant side effects are less likely.
