"In the textbook Evolutionary Psychology, the authors explain that a particular hunter gatherer population isn’t as susceptible to PTSD despite being exposed to similarly tragic events. They argue that part of the physiological changes that come along with PTSD are increased inflammation in the body. Thus, the inflammatory nature of a standard western diet may make some people more susceptible to PTSD."

Where is the proof that diet causes PTSD?
