What causes inflammation (cause of heart attacks)? Health expert shares 10 surprising reasons

Chronic inflammation has quietly emerged as a driving force behind several serious health disorders, including cardiovascular disease, metabolic conditions, and even cancer. While inflammation is a natural defense mechanism, problems arise when it becomes persistent and unchecked. Highlighting this concern, health educator Dr Eric Berg recently used X to outline several everyday factors that can trigger long-term inflammatory responses in the body, along with strategies to counter them.

Gluten and Hidden Food Sensitivities

One of the most overlooked contributors to inflammation is gluten intake and unrecognized food allergies. Gluten can compromise the lining of the small intestine, leading to a condition commonly known as a leaky gut. When this barrier weakens, undigested food particles may enter the bloodstream, provoking immune reactions and widespread inflammation. Identifying and eliminating specific food sensitivities often helps calm gut-related inflammation.

Ultra-Processed Foods and Chemical Additives

Highly processed foods are another major inflammatory trigger. Ingredients such as artificial sweeteners, refined starches, and industrial seed oils undergo heavy processing that strips them of natural nutrients. These substances can generate oxidative stress, damage cells, and promote chronic inflammation throughout the body.

Viral Activity and Immune Suppression

Certain viruses can remain dormant and reactivate periodically, creating recurring inflammatory episodes. Stress plays a significant role here, as elevated cortisol levels can weaken immune defenses. Additionally, some viral infections interfere with vitamin D absorption, further impairing the body’s ability to regulate inflammation.

Insulin Resistance and Frequent Eating

Regular snacking and excessive carbohydrate consumption can gradually lead to insulin resistance. This metabolic imbalance is now widespread and is closely linked to chronic inflammation, weight gain, and an increased risk of type 2 diabetes.

Cortisol Imbalance from Chronic Stress

Long-term stress or prolonged use of steroid medications can disrupt cortisol function. Instead of responding effectively, the body may develop cortisol resistance, which interferes with inflammation control and immune balance.

Old Injuries and Physical Inactivity

Past injuries combined with a sedentary lifestyle can keep inflammation lingering in muscles and joints. Limited movement reduces circulation and prevents proper healing, allowing inflammatory processes to persist.

Bile Duct Congestion and Liver Stress

Inadequate bile flow can cause thickened bile to accumulate and back up into the liver. This may result in discomfort, particularly around the right shoulder and upper back. Nutrient-dense diets and improved liver support can help restore healthy bile movement.

Excess Iron Levels

Elevated iron stores, often linked to genetic factors and more common in men, can promote oxidative damage. Too much iron in the body fuels inflammation and increases the risk of organ stress.

Oxygen Deprivation in the Body

Conditions such as sleep apnea, chronic lung disease, liver scarring, or narrowed arteries can reduce oxygen delivery to tissues. This state, known as hypoxia, creates an environment where inflammation thrives.

Uric Acid and Fructose Intake

High uric acid levels, frequently associated with excessive fructose consumption, are a significant contributor to inflammation and elevated blood pressure.

Effective Ways to Reduce Inflammation

Dr Berg also emphasized practical remedies to combat inflammation. These include consuming fermented foods or probiotics to support gut health, maintaining optimal vitamin D3 levels, practicing intermittent or extended fasting, and eating plenty of cruciferous vegetables. Dietary approaches such as ketogenic or carnivore-style eating, along with supplements like TUDCA and tocotrienols, may offer additional support. Cold exposure, regular stretching, physical activity, and omega-3-rich foods like sardines, salmon, and cod liver oil are also beneficial.

Understanding Inflammation

Inflammation is the body’s natural reaction to injury, infection, or harmful substances. It plays a vital role in healing and protection, as seen in responses like fever during illness. However, when inflammation occurs without a clear threat or continues for extended periods, it can damage healthy tissues and contribute to chronic disease. Managing its root causes is key to long-term health and resilience.
