Beef on the menu: could a daily serving boost heart health in older adults?
NCT ID NCT05236374
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether eating beef every day as part of a heart-healthy diet helps older adults (ages 55-70) absorb zinc better and improves how their blood vessels work. Researchers will measure zinc levels in cells and blood vessel function in 20 participants. The goal is to understand if beef's natural nutrients can support cardiovascular health in people at higher risk for zinc deficiency and heart disease.

What this could lead to
If it works, this could show that including lean beef in a heart-healthy diet helps older adults absorb zinc better and supports blood vessel health.
What could go wrong
This is a very small early-stage study with only 20 participants, so results may not apply to everyone. It is not designed to prove that beef prevents or treats any disease.
