I have been following a line of research that links inflammation and depression. For example, it has been shown that levels of inflammation can be 40% to 50% higher in depressed people compared to non-depressed people. In fact, some researchers believe that inflammation the primary cause of depression. It is now a matter of finding out what physical and mental stressors activiate inflammation in certain people.
This is interesting to me because diet and exercise play a large role in regulating the body's level of inflammation. Other studies have shown that exercise can often treat depression. Could the link be through exercises beneficial effects on inflammation?
As I talked about in this post, intermittent fasting can help reduce inflammation as well. And of course, eating more along the lines of a Paleo diet will help to reduce inflammation as well.
Researchers are now looking at anti-inflammatory medicines as a way to treat depression. Hopefully, they will not overlook the power of diet and exercise to lower inflammation as well.
