#Oliveoil

A groundbreaking new study has put olive oil—the so-called “liquid gold” prized in cuisines from Mediterranean to modern Thai kitchens—under the spotlight for its potential effects on body fat. The research, published in the prestigious journal Cell Reports and widely covered by the media (NY Post), suggests that high levels of oleic acid, the primary monounsaturated fat in olive oil, can trigger a rapid rise in the number of “fat cell soldiers” in the body. While olive oil has long been lauded for its heart-healthy and antioxidant-rich profile, this new evidence suggests its impact on obesity and metabolic health may be more complex than previously thought.

The sizzling question of whether cooking with olive oil destroys its precious nutrients has long lingered in Thai kitchens, especially as more families embrace olive oil for both flavor and health. A recent interview with food scientist Jessica Gavin, featured in an article published April 14, 2025, by EatingWell, unpacks the science and sets the record straight: while cooking does cause some nutrient loss—mainly antioxidants—olive oil remains one of the healthiest and most versatile fats for everyday use, so long as it’s used within recommended temperature limits (EatingWell).
