Health experts warn against popular olive oil trend touted by Kourtney Kardashian, Hailey Bieber

Olive oil shots, promoted by celebrities including Kourtney Kardashian and Hailey Bieber, have spread on social media as a supposed wellness practice. Nutrition expert Megan Meyer says olive oil can be part of a healthy diet, but taking it as a shot is unnecessary and may add enough calories to contribute to weight gain.

Olive oil contains monounsaturated fat and polyphenols, whose levels vary by type; extra virgin oil generally contains more polyphenols than refined light-tasting oil. A 2022 observational study found that adults consuming more than half a tablespoon daily had a 19% lower risk of death from heart disease. Meyer says shots may also cause stomach upset or reflux, and advises people with gallbladder problems or sensitive stomachs to avoid them.
