Omega-6 fatty acids and violence?

I’ve been reading the book “The Big Fat Surprise” which strongly makes the argument that foods high in saturated fat have been unfairly chastised for being unhealthy. I think the author is probably on to something though there’s so many variables at play in these discussions it’s hard to keep it all straight in your head.

The book does bring up an interesting point that I have seen made before (specifically in a book I discussed here called “The Anatomy of Violence.”) There seems to be a real correlation between consumption of Omega-6 fatty acids (which are found in the vegetable oils that became popular as alternatives to oils high in saturated fats) and suicide and violence. The following Psychology Today article looks specifically at the violence part of the equation.

Violence: Are There Dietary Causes?

One major dietary change that may have contributed to rising rates of violence has been the shift toward omega-6 rich seed oils, such as soybean oil and corn oil, in foodstuffs.

Joseph Hibbeln and collaborators had the idea of comparing omega-6 consumption to rates of violence. They found, across countries and over a period of decades, that omega-6 consumption was correlated to homicide rates…

It seems pretty absurd that diet could cause violence (we all jokingly recall the Twinkie defense) but I think we do have some sense that our mood is affected by what we eat. Certainly I’m less likely to go out and kill after having a satisfying meal.

I’m not sure what to make of it all but it’s an interesting observation.
