If the question is purely based on scientific evidence around cardiovascular protection, extra virgin olive oil currently has stronger global research support.
The evidence around olive oil and reduced cardiovascular risk is broader, deeper, and more consistent across populations.
But that does not automatically make mustard oil unhealthy.
For Indian diets, cold-pressed mustard oil used in moderate amounts can still be part of a heart-friendly lifestyle, especially when meals are rich in vegetables, pulses, whole grains, nuts, and physical activity.
The bigger truth is this: no oil alone can “save” the heart.
A person cannot eat ultra-processed food daily, sleep poorly, avoid exercise, and then expect one expensive bottle of olive oil to undo the damage. Heart health depends on the full pattern of living.
Nutrition experts say that diversity may be smarter than loyalty to a single oil. Rotating oils thoughtfully, avoiding repeated reheating, and controlling quantity may matter more than blindly following trends.
In fact, some cardiologists suggest that the healthiest kitchen is not the one with the most imported oil, but the one where fresh food is cooked mindfully.
