Evidence report · Heart and cholesterol
Extra virgin olive oil is a well-supported everyday fat for heart and metabolic health. Use it raw or at low heat. Quality matters: many bottles labeled 'extra virgin' are adulterated, and benefits track polyphenol content and freshness. Most of the evidence comes from Mediterranean diet studies rather than olive oil alone.
