Top 4 Root Causes of Inflammation

The Hidden Drivers of Chronic Inflammation

Inflammation has become one of the most talked-about culprits in modern health — the culprit behind everything from joint pain, chronic fatigue, to chronic diseases like IBS, arthritis, and diabetes.

The Main Culprit: Poor Gut Health

Poor Diet Destroys the gut.

And poor gut health results  in inflammation throughout the body.

70%-80% of the immune system lies in the digestive tract, these immune cells form a specialized network known as the gut-associated lymphoid tissue (GALT).

The gut is also home to trillions of good bacteria.  These beneficial bacteria train the immune system to react to bad invaders.

Bad diet leads to overgrowth of bad bacteria in the gut, and lack of good bacteria. Without the good gut bacteria our immune system is completely lost.

It can even start attacking the body itself, which is characterized by inflammation and auto-immune conditions.

The funny thing is that many people believe they are eating well, but when I ask them to describe their daily diet, they mention fish, which is one of the most toxic foods you can possibly eat in 2026.

Fish is full of heavy metals, parasites and vaccines doesn't matter whether it is "wild" or farmed- our oceans are contaminated, so unless you're catching it yourself in the deep sea and eating with a day or two, don't eat it. They also list cheese or dairy.  It's amazing that people still think that cheese is healthy, it's really not. Most Dairy, especially cheese, is highly inflammatory. 

Other foods to avoid are refined processed foods, chemicals and preservatives in foods (pretty much all processed packaged foods contain preservatives), animal proteins, fish and trans fats.

Over time, the irritation and toxins from these foods  contribute to gut inflammation and increased intestinal permeability, sometimes called "leaky gut," which allows particles to pass into the bloodstream. These particles trigger the immune system, which results in overall body inflammation.

Conclusion: Bad Gut Health=Inflammation

Ultra-Processed Foods and Free Radical Damage

Many ultra-processed foods rely on industrially processed ingredients — refined corn derivatives among them — that can generate free radicals during processing or digestion. Free radicals are unstable molecules that damage cells when left unchecked, and that cellular damage is a direct trigger for the body's inflammatory response.

Viruses, Stress, and Cortisol

Viral infections can set off inflammatory conditions that persist well beyond the initial illness. Chronic stress compounds this: prolonged elevated cortisol can suppress healthy immune function, making it harder for the body to fully resolve inflammation once a virus — or any other trigger — has set it in motion.

Insulin Resistance From Frequent Eating

Eating frequently, especially foods high in refined carbohydrates, keeps insulin levels elevated throughout the day. Over time, cells can become less responsive to insulin's signals — a state known as insulin resistance — which is closely linked to chronic inflammation. 

Lack of Motion

Sitting or inactivity leads to increased abdominal fat (visceral fat).  Immune cells (macrophages) infiltrate this fat tissue. Fat cells then release inflammatory proteins called cytokines.

Inactivity or lack of movement also causes cells to be less sensitive to insulin.  This leads to spikes in blood sugar, which damages blood vessels and triggers inflammation.

Bile Duct Sludge and Liver Strain

The liver is supposed to filter out toxins that enter the body.  Toxins from medications can accumulate in the liver, causing a backlog. When the liver gets clogged up, these toxins start to backflow back into the body causing widespread inflammation.

Additionally, When cholesterol becomes overly concentrated in bile, it can thicken into "sludge" within the bile ducts, contributing to liver inflammation. Diet is crucial here. Reducing the intake of foods that concentrate the bad LDL cholesterol in bile, such as animal protein and dairy, while supporting liver function through intake of plant based whole foods will help to stop the accumulation of cholesterol.

Uric Acid and Fructose

High fructose intake — common in sweetened beverages and processed foods — is metabolized in a way that raises uric acid levels in the body. Animal Protein consumption also causes high uric acid levels in the body.

Elevated uric acid has been linked not only to gout but increasingly to high blood pressure and broader inflammatory activity. Supporting a healthy gut microbiome appears to play a role in how the body processes fructose and manages uric acid levels.

Medications: An Overlooked Source

Medications: An Overlooked Source of Inflammation

It's a strange twist, but some of the most common medicines people take can themselves contribute to inflammation — including drugs meant to relieve it.

Some medications irritate the gut to the point that you can develop IBS from taking them long term.

Take NSAIDs (like ibuprofen and naproxen). With regular, long-term use, research shows they can damage the lining of the small intestine — studies have found measurable increases in intestinal permeability (leaky gut) in roughly half to two-thirds of long-term users, alongside changes to the gut microbiome (too much bad bacteria) that trigger inflammation. In effect, a drug taken to calm inflammation in one place can quietly generate it in another.

Antibiotics By design, wipe out harmful bacteria — but they can significantly kill off a ton of beneficial gut bacteria in the process. Since a healthy, diverse microbiome plays a direct role in regulating the body's immune and inflammatory responses, disrupting it — especially with repeated or broad-spectrum antibiotic use — can leave the body more prone to inflammatory activity, sometimes in organs far from the gut itself.

Sulfonylureas, an older class of diabetes medication that prompts the pancreas to release more insulin, are another good example. They're linked to weight gain and, in some studies, a higher risk of cardiovascular events — both of which feed back into the insulin resistance and excess-fat pathways already covered above.

Similarly, thiazide diuretics, a common first-line blood pressure treatment, have long been known to worsen glucose tolerance and insulin sensitivity in some patients, which triggers inflammation on its own.
