I'm a bit surprised you didn't mention inflammation management. The western diet almost entirely consists of inflammatory foods - refrigerated dough, packaged snacks, burgers etc.
Whilst my tennis elbow is probably caused by poor ergononics and not warming up properly before exercising, I'm finding tiger milk mushroom, a known anti-inflammatory [1] is helping a great deal.
In my case I didn't find much impact from diet and any blood tests I did showed no signs of inflammation. Though as I mentioned closer to the end of the post, I think generally focussing on your health (and I'd include diet in this) is always good. Most things might not have an impact but something often will.
Can you send me a screenshot or something?
Edit: Damn looks like it is Disqus, I'm going to remove that. I've got no interest in running ads.
