Saturated Fats Are Good?
Written by Tim Rigby

We wouldn't go quite that far, however some recent studies have suggested that a diet high in saturated fats can re-program the immune system. What does that mean for us? Well, let's find out.

A team of scientists from Portland State University (Oregon) studied the influence of a diet high in saturated fats in groups of mice and achieved some contrasting discoveries.  Surprisingly, there’s a bit of good news: it seems the saturated fats consistently re-programmed their immune systems, subsequently helping the mice build a better “short-lasting innate immunity” to ward off infection.  So far, so good.

However, as you’d expect, such a diet is a double-edged sword which also carries some significant detriments.  The most impactful negative here is that such a diet made the mice more susceptible to systemic inflammatory conditions including sepsis.  This is a great concern, because it rapidly transforms a relatively minor infection into one that spreads throughout the entire body and can effectively poison the blood.

As applied to humans, a diet high in saturated fats is not recommended, despite the popularity of the so-called “keto” diet fad sweeping the western world.  When people begin a “keto” diet, they severely lower the amount of carbohydrates consumed and quickly lose a lot of weight due to the water loss.  Consuming high saturated fats, of course, will not quicken the rate of fat loss.  This study was published in the journal eLife.
