Robert F. Kennedy, Jr. thinks that seed oils—like sunflower or soybean oil—are causing terrible damage to people’s health. And now he’s the US Health Secretary (wait, what?!) we should probably take him seriously.
In this episode of The Studies Show, Tom and Stuart trace the origins of the idea that seed oils are uniquely unhealthy, and look at all the best evidence from randomised trials on whether it’s remotely true.
The Studies Show is sponsored by Works in Progress magazine, where you can find detailed, beautifully-written essays on technology and progress. If you need something to read that’s full of unexpected and inspiring ideas about how science and technology can make the world better, you can be confident that you’ll find it at worksinprogress.co.
