A key concept in health is the proper management, regulation and control of inflammatory processes in the body.
Inflammation is a naturally occurring response to tissue damage and to infection (from viruses, bacteria etc.).
Healthy people produce appropriate inflammatory responses, and resolve or control them (healing) properly.
A wide variety of health problems ranging from headaches, depression, gut problems, spinal problems, arthritis and so on, appear to be related to the improper control and regulation (dis-regulation) of inflammatory processes. For an example of the possible link between Parkinson’s disease and inflammation, see this.
So any dietary approach that helps this problem is going to be a good idea!
