Multiple randomized controlled trials published between January and April 2026 report a 14-22% reduction in mortality risk among participants consuming at least 20-30 ml of olive oil daily, alongside measurable improvements in inflammatory markers such as C-reactive protein.
What the research found
The identified optimal intake range — roughly 20-30 ml per day, or about 1.5 to 2 tablespoons — appears consistent across several 2026 trials. Researchers also found that extra virgin olive oil with polyphenol content above 250 mg/kg delivered the most significant benefits.
An important caveat
Researchers caution against oversimplifying olive oil’s role in isolation. Most study participants also followed broader Mediterranean-style diets and maintained other healthy lifestyle habits — meaning olive oil intake works alongside, not as a replacement for, overall dietary quality.

FAQ
How much olive oil should I consume daily for health benefits? Current 2026 research points to 20-30 ml (roughly 1.5-2 tablespoons) daily as the range associated with measurable benefits.
Does any olive oil provide these benefits, or just high-polyphenol grades? The strongest effects were linked to oils with polyphenol content above 250 mg/kg — the EU’s minimum threshold for making health claims.
