“It is in 50% of products on supermarket shelves, and like you said, every person touches it every day, including me, who tries not to, but it's ubiquitous, and it is in everything from soaps and shampoos To lipstick and laundry detergent, to most of the foods that you find at the grocery store, from peanut butter, to cookies, to frozen pizzas.”

The claim, plainly

Palm oil is an ingredient present in 50% of products on supermarket shelves.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

The statement repeats a widely circulated talking point originating from an internal WWF estimate around 2006 and echoed by advocacy groups like RSPO and RAN. However, empirical retail inventory audits contradict the 50% figure. A comprehensive multi-country supermarket audit published in Environmental Research: Food Systems (2025) found that direct palm oil or palm kernel oil is listed on only 7.9% of packaged supermarket products. Even when accounting for probable palm oil derivatives and oleochemicals, the prevalence is estimated between 18% and 33%, and reaches approximately 40% only under an extreme upper-bound scenario where all ambiguous vegetable oils and oleochemicals are assumed to be palm-derived. Because the actual prevalence falls well short of 50%, the claim materially overstates palm oil's presence on supermarket shelves.

A 2025 Wageningen University / Borneo Futures audit of ~1,600 packaged products across major UK, Dutch, and Australian supermarkets found palm oil directly listed on only 7.9% of products.
Accounting for probable derivatives and oleochemicals raised estimated prevalence to only 18%–33%, with an extreme upper-bound sensitivity cap of ~40%.
The 50% statistic originated from an unverified internal WWF estimate circa 2006 and lacks empirical support in rigorous shelf audits.
