How does Adam Ringham's perspective on 'liquid plastic' challenge conventional health advice?

“Liquid plastic” is the label given to industrial seed and vegetable oils that are marketed as “heart healthy”—things like canola, soybean, and other highly processed oils. The perspective is that these are ultra‑processed, unstable fats sold as healthy while truly nourishing fats (like good-quality animal fats) have been demonized.

This flips conventional advice on its head: instead of fearing traditional fats, the challenge is to question why chemically refined, factory-made oils are pushed as the healthy option.
