Vegetable oils
– the evidence

 
This guide is based on scientific evidence, following our policy for evidence-based guides.

It’s written by Jennifer Callihan and published December 15, 2018. It was medically reviewed by Dr. Bret Scher, MD, on December 14, 2018.

The guide contains scientific references. You can find these in the notes throughout the text, and click the links to read the peer-reviewed scientific papers. When appropriate we include a grading of the strength of the evidence, with a link to our policy on this. Our evidence-based guides are updated at least once per year to reflect and reference the latest science on the topic.

All our evidence-based health guides are written or reviewed by medical doctors who are experts on the topic. To stay unbiased we show no ads, sell no products and take no money from industry.1 We’re fully funded by the people, via an optional membership.2

Disclaimer: Vegetable oils are still often recommended as “heart healthy”. There is high-quality evidence demonstrating that replacing saturated fat with vegetable oils reduces LDL cholesterol levels. But there’s no high-quality evidence that this translates into fewer heart events or lower rates of cardiovascular mortality. Because of lack of evidence of health benefits, potential negative health effects, concerns about the highly refined and unstable nature of these oils and due to evolutionary considerations, we believe that the conventional recommendations about vegetable oils are flawed.

This guide is written for all readers.

Controversial topics related to vegetable oils, and our take on them, include saturated fats and cholesterol.
