There was a time when I would have told you inflammation was the root cause of chronicdisease. I still believe that’s true. But over the last several years, I’ve gone further upstream,and what I found there has become some of the most exciting research of my career.
Here’s the question that kept pulling me forward: if inflammation really is the root cause, thenwhat causes the inflammation? What kind of dysfunction perpetuates it, keeps it running longafter it should have resolved? The answer, I’ve come to believe, traces back to the immunesystem itself, a system present in every organ of the body, not confined to any one location, notsomething you can point to on an anatomy chart the way you can the heart or the liver.
Inflammation Isn’t One Thing
Part of the problem is how casually we talk about inflammation, as if it’s a single villain to eliminate. It isn’t. Inflammation is a process, and like most biological processes, it can go two very different directions. It can damage. It can also heal. A sprained ankle, a healing wound, a fever fighting off infection, all of that is inflammation doing exactly what it’s supposed to do. The trouble isn’t inflammation existing. The trouble is inflammation that doesn’t know how to stop.
That distinction matters enormously, because it changes the entire question we should be asking. The goal was never to eliminate inflammation. The goal is figuring out why it sometimes fails to resolve.
The Immune System Is Smarter Than We Give It Credit For
This is where the real answer lives, and it’s more remarkable than I think most people realize.The immune system is intelligent. It knows, under healthy conditions, precisely when to switchspecific inflammatory processes on, and precisely when to switch them back off. It’s not a bluntinstrument running one setting. It’s a highly coordinated system making constant, granulardecisions about where a response is needed and where it isn’t.
Managing inflammation, then, isn’t really about suppressing it. It’s about restoring the immunesystem’s own resilience, its ability to make those decisions well, to mount a response whensomething genuinely calls for one, and to stand down cleanly once the job is done. Thatcapacity for resilience, more than any single anti-inflammatory intervention, is what I think weshould actually be targeting.
What Throws the System Off Course
So what interferes with that intelligence? A great deal of it, in my experience, traces back toultra-processed foods and the broader pattern of unhealthy lifestyle habits that have becomenormal in modern life. These inputs don’t just cause a single flare-up. They can prompt andperpetuate a state of chronic inflammation and immune dysfunction, keeping the systemlocked in a low-grade “on” position it was never designed to sustain indefinitely.
This is the upstream dysfunction I mentioned. It’s not that any one of us is simply prone toinflammation. It’s that the immune system’s ability to regulate itself gets worn down over time,by the same handful of everyday exposures, repeated often enough.
The System Can Be Rejuvenated
Here’s the part I find most hopeful, and honestly, most exciting. The immune system isn’t afixed structure you’re stuck with. It’s dynamic, constantly generating new cells, which means it’salso constantly capable of change. That gives us real leverage.
The immune system can be rejuvenated through diet, targeted nutrient support, theenvironment you’re in, how you manage stress, and the broader lifestyle choices you make dayto day. None of these are minor tweaks around the edges. They’re direct inputs into a systemthat is, quite literally, remaking itself all the time. The question isn’t whether the immunesystem can change. It’s whether we’re giving it what it needs to change in the right direction.
Why This Matters for the Long Run
Emerging science is increasingly pointing to this as one of the best approaches available foroptimizing healthspan and longevity, not chasing inflammation after the fact, but supportingthe immune resilience that determines whether inflammation resolves the way it’s supposed toin the first place.
That shift, from fighting inflammation to understanding the intelligence behind it, is what’s keptme energized in this work. I went looking for the root cause of chronic disease and foundsomething even more interesting waiting one level further upstream: a system smart enough toheal itself, if we give it the chance.
