Summary

This study is testing whether a year-long program of daily blueberries, protein powder, and three weekly exercise sessions can reduce frailty and lower the risk of heart disease in older adults. Researchers will enroll 240 people aged 65 and older in Nova Scotia. The goal is to see if this combined lifestyle approach can improve fitness, reduce inflammation, and promote healthier aging.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
whey protein isolate powder and blueberries
What this could lead to
If it works, this could show that a simple diet and exercise plan can lower frailty and heart disease risk in older adults, pointing toward a practical way to promote healthy aging.
What could go wrong
This is a mid-sized study testing a combination of lifestyle changes, not a new drug. Results may not apply to everyone, and the benefits might be small or hard to separate from other factors.
