India, April 8 -- A viral claim circulating online suggests that eating pomegranate can strengthen heart muscles and increase the force of cardiac contraction (1).
However, available clinical evidence described in the report does not support this claim. The evidence shows that pomegranate may improve blood flow, reduce oxidative stress, and support cardiovascular health, but it does not increase heart muscle strength or pumping ability .
What Is the Viral Claim About Pomegranate and Heart Strength?
The claim suggests that consuming pomegranate can directly enhance heart muscle power and act similarly to medicines that increase the force of contraction.
This is misleading because it equates general cardiovascular benefits with myocardial contractility, which refers to the heart's ability to contract and pump blood. There is no clinical evidence showing that pomegranate affects this function
What Clinical Research Actually Shows
A randomized controlled trial (RCT) in patients with coronary heart disease (CHD) evaluated daily pomegranate juice consumption over three months (sample size not specified in the report).
Key findings include:
Improvement in stress-induced myocardial ischemia
No significant change in key cardiac parameters
No increase in heart contraction strength
These findings indicate improved blood flow rather than stronger heart muscle performance.
The report also describes findings such as reductions in angina symptoms, oxidative stress, and cardiovascular markers, indicating protective effects rather than increased heart muscle strength
How Pomegranate Supports Heart Health Indirectly
Pomegranate contains compounds that act on blood vessels and metabolic pathways rather than heart muscle cells.
These effects include:
Reduction in oxidative stress
Improvement in vascular function
Reduction in plaque-related processes
Support in lowering blood pressure
These mechanisms help reduce cardiovascular risk but do not increase contraction strength.
