The discussion over what aspect of our diet has been driving the escalation of metabolic disease over the last 100 years has been a confusing one full of contradictory information.

It would be logical to look for a change in our diet associated with such a dramatic change in the health of a population

There are both correlated evidence and dietary trials to support the theory that the increase in linoleic acid, provided by the introduction of PUFA processed oils into our diet, is the driver.

In this episode of Hunger Hunt Feast, I want to share a collection of them to help clarify some of the confusion.
