Summary

This study investigates whether high-protein meals, especially from animal sources, activate immune cells in a way that could worsen atherosclerosis (hardening of the arteries). Researchers will give 24 adults different protein-rich meals and measure changes in blood cells. The goal is to understand if protein type and amount influence heart disease risk, which could reshape dietary advice.

What this could mean

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

Active substance: dietary protein (animal vs. plant sources)
What this could lead to: If successful, this could reveal whether high-protein diets, especially from animal sources, contribute to heart disease, and point toward safer dietary recommendations.
What could go wrong: This is a small, early-stage study in 24 people, so results may not apply broadly. It only looks at short-term cell changes, not actual heart attacks or strokes.
