Summary

This study tests whether eating one avocado daily for 4 months can slow biological aging in 120 female breast cancer survivors. The researchers will measure changes in telomere length (a marker of cellular aging) and other health indicators like inflammation and heart disease risk. Participants will either eat an avocado each day or follow their usual diet with fewer than two avocados per week.

What this could mean

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

Active substance: avocado
What this could lead to: If it works, this could point toward a simple dietary change to help breast cancer survivors age more slowly and reduce long-term health risks.
What could go wrong: This is a small, early-phase trial (120 people) testing a biomarker, not a direct health outcome. Results may not lead to a proven treatment or apply to everyone.
