Diet and chronic pain: fact or fiction?



“We interrupt this previously-planned blog post to bring you this breaking news. Recent anecdotal evidence supports the notion that diet might have a big impact on chronic pain.”

That’s the 1960s-style news spot that is running through my head as I begin to write this post.  I was planning a different topic altogether, but a sudden aha! moment in the shower today compelled me to change my mind.

Specifically, as I was hurrying to get ready this morning, I gazed down through the lather to take note of my pesky right knee.  Normally, it makes its presence known on an ongoing basis. In recent days, however, it hasn’t been talking to me.  At all.  Strange.  Very strange.

As I ran through a mental list of what might account for this sudden change, I struck upon a distinct possibility.  In recent weeks, I’ve changed my diet.  Specifically, I’ve stopped eating food that contains added sugars, fruit, processed grains (wheat, flour, rice, etc.), or root vegetables (potatoes, carrots, etc).  My new diet consists mainly of lean meats, dairy, vegetables, nuts and legumes.  

I made this change because I’ve added a few pounds during 2012 that I want to shed.  (Never mind that so far I’ve lost almost nothing, while my husband, who isn’t even on the diet, has lost three pounds!) Pain was the last thing on my mind when I decided to change what I eat.

So what does science have to say about the food-pain connection? Most of the evidence comes from small studies.  Large-scale randomized trials (the gold standard of clinical evidence) haven’t been conducted.  Some experts speculate that certain diets – such as the one I am following – reduce inflammation in the body, which in turn lessens chronic pain.

The strongest known connection between food and chronic pain is through obesity.  Carrying extra weight puts tremendous strain on joints, especially in the spine, hips, and knees.  New evidence also suggests that obesity might fuel pain through the impact of fat cells on inflammation throughout the body.

Obesity is not a factor in my situation.  Honestly, I don’t know what to make of my lack of knee pain.  I would be the first to acknowledge that its connection to my dietary change might be ‘spurious’ (a favorite term of scientists – basically meaning not really true).  Stay tuned.

In the meantime, I’ve listed a couple of articles (below) that discuss the potential pain-relieving properties of certain foods.
