Inflammation is a natural response of the body's immune system to protect itself from harmful stimuli such as damaged cells, pathogens, or irritants. It is a complex biological process involving various immune cells, signaling molecules, and biochemical pathways.
When the immune system detects a threat, it triggers an inflammatory response that results in increased blood flow, swelling, and production of immune cells. The purpose of inflammation is to eliminate the harmful stimuli and initiate the healing process.
Inflammation can be acute or chronic. Acute inflammation is a short-term response to injury or infection, while chronic inflammation persists over a more extended period and can contribute to the development of many chronic diseases, such as arthritis, diabetes, heart disease, and cancer.
Chronic Inflammation
Chronic inflammation is a persistent low-level inflammatory response that can lead to tissue damage and dysfunction over time. When the immune system is activated for prolonged periods, it can cause a buildup of inflammation that can damage healthy cells and tissues, leading to chronic diseases.
Chronic inflammation can be caused by a variety of factors, including:
- Poor diet: A diet high in processed foods, refined sugars, unhealthy fats, and low in fruits and vegetables can lead to chronic inflammation.
- Chronic alcohol consumption.
- Sedentary lifestyle: Lack of physical activity can contribute to inflammation.
- Environmental toxins: Exposure to toxins such as air pollution, pesticides, and heavy metals can trigger inflammation.
- Chronic stress: Stress triggers the release of stress hormones that can lead to inflammation.
- Smoking: Cigarette smoke contains harmful chemicals that can trigger inflammation.
- Obesity: Excess body fat can promote inflammation throughout the body.
- Chronic infections: Persistent infections such as hepatitis C, HIV, and Lyme disease can cause chronic inflammation.
- Autoimmune disorders: Autoimmune disorders such as rheumatoid arthritis, lupus, and multiple sclerosis involve chronic inflammation.
Why We Need to Reduce Chronic Inflammation
Research has shown that chronic inflammation is associated with several diseases, including cardiovascular disease, diabetes, cancer, Alzheimer's disease, and autoimmune disorders. Chronic inflammation can also lead to insulin resistance, a condition in which cells do not respond well to insulin, increasing the risk of developing type 2 diabetes.
Reducing chronic inflammation can have numerous benefits for overall health and well-being. Some of the potential benefits of reducing chronic inflammation include:
Cardiovascular Disease
Many clinical studies have shown strong and consistent relationships between markers of inflammation and cardiovascular disease prediction. Furthermore, Atherosclerosis is a pro-inflammatory state with all the features of chronic low-grade inflammation and leads to an increase in cardiovascular events such as myocardial infarction, stroke, among others.
Chronic Obstructive Pulmonary Disease (COPD)
Chronic airway inflammation has been indicated as a major risk factor in COPD and has been suggested to be associated with an increased risk of cancer, including lung cancer. Therefore, it can be hypothesized that COPD and lung cancer may share chronic inflammation as one of the common pathogenic mechanisms.
Cancer
The latest evidence seems to suggest that when a group of cells becomes cancerous and begins the tumor creation phase, they hijack other cells such as fibroblasts, and immune cells into the forming tumor. The incorporation of these immune cells gives them some level of protection against the body's immune system itself. This is all made possible when the tumor is enmeshed in a pro-inflammatory environment.
While the immune system has the ability to seek out and destroy cancerous tumors, the resulting inflammation not only blocks anti-tumor immunity, but it exerts direct tumor-promoting signals and functions onto epithelial and cancer cells. This is the paradoxical trade-off that evolution has dumped on us.
Diabetes
Researchers discovered that in people with type 2 diabetes, cytokine levels are elevated inside fat tissue. Their conclusion: Excess body fat, especially in the abdomen, causes continuous (chronic), low levels of abnormal inflammation that alters insulin's action and contributes to the disease.
As type 2 diabetes starts to develop, the body becomes less sensitive to insulin and the resulting insulin resistance also leads to inflammation. A vicious cycle can result, with more inflammation causing more insulin resistance and vice versa. Blood sugar levels creep higher and higher, eventually resulting in type 2 diabetes.
Alzheimer’s Disease
Amyloid beta are peptides (amino acids) that are the main component of the amyloid plaques found in the brains of people with Alzheimer's disease. These amyloid-beta molecules can aggregate into forms that are toxic to nerve cells.
Amyloid-beta fragments are believed to be one of the main causes of Alzheimer’s disease, accumulating in the brain and leading to brain cell death.
The latest experiments have shown that increasing the markers for inflammation and the subsequent increase in inflammation levels lead to higher levels of amyloid-beta.
Other Disorders Include:
Inflammatory cells can accumulate in the arterial walls, causing the development of atherosclerosis, which is a major risk factor for heart attacks and strokes.
Autoimmune disorders, such as rheumatoid arthritis, lupus, and multiple sclerosis, occur when the immune system mistakenly attacks healthy cells and tissues, leading to chronic inflammation and tissue damage.
What We Can Do About It
First The Low-Hanging Fruit
- Quit smoking
- Avoid environmental toxins
- Minimize alcohol consumption
If we can’t get these under control, the solutions that follow, while still important, will be like putting lipstick on a pig.
Improved Diet
What to Eat
Research has shown that specific nutrients and dietary components can have anti-inflammatory effects in the body. For example, omega-3 fatty acids found in fatty fish like salmon, mackerel, and sardines, as well as in flaxseeds and walnuts, have been shown to decrease the production of pro-inflammatory cytokines. Similarly, foods rich in antioxidants, such as berries, leafy greens, and cruciferous vegetables, can help to neutralize free radicals and decrease oxidative stress, which is a contributing factor to chronic inflammation.
What to Cut Out
On the other hand, diets high in refined carbohydrates and sugars, such as the standard Western diet, can cause insulin resistance and metabolic dysfunction, leading to chronic inflammation. Consuming high levels of processed and fried foods can also increase inflammation due to their high content of unhealthy fats and low nutrient density.
Cardiorespiratory Training
Research has demonstrated that consistent aerobic exercise can lower the levels of inflammatory markers in the body, including C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha).
Cardiovascular exercise can also improve insulin sensitivity, which in turn can reduce inflammation. Insulin resistance is linked to chronic inflammation, and improving insulin sensitivity can help lower inflammation levels. Additionally, regular cardio exercise can help with weight management, which is another important factor in reducing chronic inflammation.
However, it is important to note that excessive and intense cardio exercise can also cause inflammation in the body. Therefore, it is recommended to engage in moderate-intensity cardio exercise for optimal benefits without causing excessive stress on the body.
Strength Training
Studies have shown that regular strength training can lower levels of inflammatory markers in the body, such as C-reactive protein (CRP) and interleukin-6 (IL-6).
One way that strength training reduces chronic inflammation is by promoting muscle growth and repair. When you lift weights, your muscles undergo small tears, which triggers an inflammatory response. However, this response is a normal part of the muscle repair process and is not the same as chronic inflammation. Over time, as you continue to strength train, your muscles adapt and become stronger, which can help reduce chronic inflammation.
In addition, strength training can also help reduce chronic inflammation by improving insulin sensitivity. Insulin resistance is a key driver of chronic inflammation, and regular strength training can help improve insulin sensitivity, which can in turn help reduce chronic inflammation.
Finally, strength training can also help reduce chronic inflammation by promoting weight loss. Excess body fat is a major contributor to chronic inflammation, and regular strength training can help you lose weight and reduce your body fat percentage, which can help lower inflammation levels.
Testosterone
There is evidence that suggests a link between testosterone levels and chronic inflammation. Testosterone is a hormone that plays an important role in many physiological processes in the body, including immune function and inflammation. Studies have shown that men with low testosterone levels have higher levels of inflammatory markers in their blood, which indicates a higher degree of chronic inflammation.
In addition, testosterone has anti-inflammatory properties, and higher levels of testosterone have been associated with reduced inflammation in several studies. Testosterone has been shown to inhibit the production of inflammatory cytokines, which are molecules that are released by immune cells and contribute to inflammation in the body.
Get Moving
Physical activity can help regulate the immune system, preventing it from overreacting and causing chronic inflammation. When the body is inactive, the immune system can become dysregulated, leading to chronic inflammation.
Physical activity can increase blood flow, which delivers oxygen and nutrients to cells and tissues throughout the body. Without adequate blood flow, cells may become stressed and inflamed.
Physical activity can stimulate the production of anti-inflammatory cytokines, which help reduce inflammation in the body. Without regular physical activity, the body may not produce enough anti-inflammatory cytokines to counteract chronic inflammation.
Physical activity can help reduce oxidative stress, which is a key contributor to chronic inflammation. Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. Regular physical activity can help increase the production of antioxidants, which can help reduce oxidative stress and inflammation.
Achieve and Maintain a Healthy Weight
So, if we are doing the above work (strength and cardio training, eating right, and getting lots of daily movement), getting to an optimum body weight and staying at that weight is well within our means. In fact it is inevitable. While each of those methods has its merits, for our purposes here (controlling chronic inflammation), whichever one suits your strengths best, feel free to make that your method of choice.
Conclusion
Overall, chronic inflammation is a common underlying factor in many chronic diseases, and managing it can help reduce the risk of developing these conditions and improve overall health and well-being.
