Chronic Inflammation at the Root of Most Diseases: Learn How to Prevent It

Inflammation is linked to just about every health condition, and chronic inflammation can raise the risk of just about every disease known to man.

What are some examples of inflammatory diseases? According to a Harvard Medical School report, “Chronic inflammation plays a central role in some of the most challenging diseases of our time, including rheumatoid arthritis, cancer, heart disease, diabetes, asthma, and even Alzheimer’s.”

Thus, one of the best things you can do for your body is to find ways to reduce and prevent inflammation in the first place.

The good news is there are a lot of ways to avoid or reduce it, including by following an anti-inflammatory diet plus other scientifically proven inflammation-reducing tactics you can start doing today.

What is inflammation?

Inflammation is part of the body’s inherent immune response, and it isn’t always bad. When it’s acute and not dangerous, it’s the body’s natural defense against damaged cells, viruses, bacteria, etc.

It aims to remove these harmful or foreign invaders and heal itself. Without it, wounds would just fester, and infections could be deadly.

A standard inflammation definition is: “a local response to cellular injury that is marked by capillary dilatation, leukocytic infiltration, redness, heat, and pain and that serves as a mechanism initiating the elimination of noxious agents and of damaged tissue.”

This is more specifically an acute inflammation definition (more on that in a minute).

What does the inflammation process look like exactly? First, chemicals from white blood cells are released into the bloodstream or the affected tissue to guard your body from foreign substances. This release of chemicals increases blood flow to the area of injury or infection.

This heightened blood flow can lead to visible redness and a feeling of warmth in the affected area. The chemical release can also trigger fluid leakage in the body’s tissues, which causes the symptom of swelling.

Nerves are often stimulated during this protective process and can cause temporary pain.

Inflammation can sometimes be mistaken for infection, but the two are not the same. Infection can, however, cause inflammation because infection is caused by harmful substances like bacteria or fungus.

In fact, inflammation is the body’s response to infection. In this way, it is good … but that’s not always the case.

Acute vs. chronic inflammation

There are two very different types of inflammation. One type is acute, and the other is chronic.

While acute inflammation starts quickly and generally disappears in a few days, chronic inflammation can last for months or years as a result of failure to eliminate the cause.

It can be beneficial when, for example, your knee sustains a blow and tissues need care and protection. However, sometimes inflammation can persist longer than necessary, causing more harm than benefit.

Symptoms

Symptoms of inflammation are different depending on whether the inflammatory reaction is acute or chronic.

Acute inflammation often occurs because of an injury to the external body or skin. Symptoms and signs of acute inflammation (which are typically on the skin) include:

• pain
• redness
• swelling
• immobility
• heat (the affected area may feel warm to the touch)

If acute inflammation occurs deep inside the body, such as in an internal organ, only some of these signs may be noticeable. For example, some internal organs like the lungs don’t have sensory nerve endings nearby, so there may not be pain even though lung inflammation may be present.

Some symptoms and signs of inflammation that is chronic include:

Ad

• fatigue
• mouth sores
• chest pain
• abdominal pain
• fever
• rash
• joint pain
• insomnia
• depression
• anxiety
• mood disorders
• diarrhea
• constipation
• acid reflux
• weight gain
• weight loss
• frequent infections
• chills
• headaches
• loss of appetite

Chronic inflammation can affect any organ. Examples of organs being inflamed include:

• swelling and loss of function of blood vessels (vasculitis)
• enlargement and loss of function of the kidney (systemic lupus erythematosus, also called SLE)
• swelling and loss of function of muscles (juvenile dermatomyositis)
• shortness of breath due to issues with the lungs

Causes

What is the main cause of inflammation in the body? There are actually several possible causes of chronic inflammation.

So what causes inflammation? A poor diet, stress, sleep issues, drinking too much alcohol, minor food allergies, a sedentary lifestyle and more can contribute to chronic inflammation.

Medical experts point out some additional possible causes as follows:

• Your individual inflammatory response: If your body doesn’t handle infection well with a normal acute or temporary inflammatory response then you could end up with some out-of-control or chronic inflammation.
• A malfunctioning protein: Researchers at Georgia State University’s Institute for Biomedical Sciences in Atlanta discovered that a protein called CYLD is key to managing the body’s inflammatory response to pathogens like bacteria and viruses and bacteria. According to the lead study author Jian-Dong Li, M.D., Ph.D., “It acts like a brake pedal to turn off that defense. Uncontrolled, overactive inflammatory response could likely be due to some defect in this brake pedal.”
• Excess weight or obesity: Extra fatty tissue produces inflammatory cytokines in the body.
• Mood changes: Chronic stress changes gene activity of immune cells before they enter the bloodstream. There’s also a suspected link between depression and increased blood levels of C-reactive protein (CRP), which increases in response to inflammation.
• Personality traits: Research has shown that people who are less conscientious are more likely to have unhealthy habits that encourage inflammation, like smoking, eating unhealthy food and exercising less.
• Your gut health: Having imbalanced gut bacteria can result in inflammation that can be behind digestive health concerns, such as irritable bowel syndrome, along with conditions outside the digestive system.
• Pollution exposure: Studies have revealed a link between greater exposure to air pollution and higher levels of inflammation-related substances in the body, including CRP and IL-6 (a pro-inflammatory cytokine).
• Foods that cause inflammation: Fried foods, processed meat, alcohol, refined carbs, artificial sweeteners, vegetable oils, high fructose corn syrup, sugar, trans fats, omega-6 foods, white flour, MSG, gluten, casein (in some people) and more are known foods that cause inflammation.

Inflammatory diseases

Examples of diseases, conditions and situations that can result in acute inflammation include:

• Sore throat due to a cold or flu
• Skin wound, such as a cut
• Infected ingrown toenail
• Some type of physical trauma/injury to the body
• Acute bronchitis
• Sinusitis
• Dermatitis

Do you already struggle with a chronic inflammatory disease? There are actually many health conditions that fall into the category of inflammatory diseases, such as:

• Asthma
• Heart disease
• Rheumatoid arthritis
• Multiple sclerosis
• Chronic peptic ulcer
• Systemic lupus erythematosus
• Periodontitis
• Ulcerative colitis
• Crohn’s disease
• Active hepatitis
• Autoimmune disorders
• Lupus
• Psoriasis
• Ankylosing spondylitis
• High blood pressure
• Certain cancers
• Irritable bowel syndrome
• Inflammatory bowel disease
• Chronic obstructive pulmonary disease
• Depression
• Anxiety
• Diabetes
• Alzheimer’s disease
• Parkinson’s disease
• Sinusitis

Diagnosis and conventional treatment

Doctors typically diagnose inflammatory diseases by reviewing your medical history and current symptoms, conducting a physical exam, and analyzing the results of any testing, including X-rays or a blood test. A simple blood test measures CRP, which is a marker of inflammation in the body.

Conventional inflammation treatment may include medication, rest, exercise and surgery (when other options don’t work). The most common over-the-counter medications conventionally recommended for short-term acute inflammation are called non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin, naproxen (Aleve) and ibuprofen (Advil and Motrin).

Acetaminophen (Tylenol) is another common pain reliever that may be recommended. However, as research has revealed, acetaminophen does not relieve inflammation.

Corticosteroids, such as cortisone and prednisone, are often prescribed as chronic inflammation treatment for conditions like arthritis and asthma. Side effects of oral corticosteroids used on a short-term basis include fluid retention, increased appetite, weight gain, insomnia and mood changes.

Side effects of oral corticosteroids used on a long-term basis (for more three months) include:

• Osteoporosis
• High blood pressure
• Diabetes
• Weight gain
• Increased vulnerability to infection
• Cataracts
• Glaucoma
• Muscle weakness
• Thinning of the skin
• Bruising easily

How to reduce inflammation in the body

1. Eat anti-inflammatory foods

As part of an anti-inflammatory diet, you’ll want to avoid the problematic inflammatory foods mentioned above while also making sure your diet is loaded with anti-inflammatory foods. These anti-inflammatory foods are also high in antioxidants, which help reduce damage caused by inflammation.

The Mediterranean diet is a great example of an eating plan that contains many anti-inflammatory foods and has been shown to decrease levels of LDL “bad” cholesterol while also lowering the risk for heart disease, Parkinson’s disease, Alzheimer’s disease and cancer.

Let’s take a look at specific foods and beverages that are wise choices while following an anti-inflammatory diet:

• Vegetables: A minimum of four to five servings per day of beets, carrots, cruciferous vegetables (broccoli, cabbage, cauliflower and kale), dark leafy greens (collard greens, kale, spinach), onions, peas, salad greens, sea vegetables and squashes.
• Fruits: Three to four servings per day of healthy fruits like apples, blackberries, blueberries, cherries, nectarines, oranges, pears, grapefruit, pineapple, plums, pomegranates or strawberries.
• Water: Make sure you drink enough water for your body weight. Sparkling mineral water or unsweetened herbal tea are other hydrating options.
• Beans and legumes: One to two servings per day of soaked and sprouted anasazi beans, adzuki beans, black beans, black-eyed peas, chickpeas or lentils.
• Healthy Fats: Five to seven servings per day of healthy fats like avocados, extra virgin olive oil, flaxseeds and hemp seeds.
• Anti-inflammatory herbs and spices: Unlimited amounts of antioxidant-rich herbs and spices like basil, chili peppers, cinnamon, curry powder, garlic,  ginger, rosemary, turmeric and thyme.
• Protein: Think organic eggs, grass-fed meats, healthy cheeses, organic poultry and cultured/raw dairy.
• Tea: Tea is an excellent natural anti-inflammatory beverage. Try having two to four cups of green, oolong or white tea per day.
• Fresh veggie and fruit juices: If you own a juicer, you can try making fresh anti-inflammatory juices, such as this anti-inflammatory juice recipe with celery, cucumber, ginger, pineapple, spinach and lemon.
• Anti-inflammatory drinks: Beverages like coffee, bone broth, apple cider vinegar drinks and ginger shots are good choices.

2. Consume red wine and quercetin-rich foods

For some people, complete elimination of alcohol is a smart choice. Talk to your doctor about whether or not you should abstain completely.

If you are going to drink alcohol, opt for organic red wine. Research studies have shown that quercetin, one of the most important flavonoids present in red wine, has potent anti-inflammatory ability along with anti-carcinogenic and antiviral activities as well. Quercetin is actually able to modulate inflammation and inhibit inflammatory enzymes.

Red wine contains another highly anti-inflammatory component known as resveratrol. According to research published in Frontiers in Aging and Neuroscience, resveratrol may control the main features of Alzheimer’s disease and slow dementia progression. This is thanks to resveratrol’s ability to reduce inflammation and oxidative stress while also acting as a neuroprotectant.

In moderation, alcohol may also help decrease LDL “bad” cholesterol, prevent blood clots and help maintain a healthy blood pressure. Typically, a woman should have no more than one drink a day and a man should have no more than two drinks per day.

This doesn’t mean you should start drinking alcohol if you don’t, but if you’re going to imbibe, organic red wine is certainly a healthier, anti-inflammatory choice when not consumed in excess. If you would rather stay away from alcohol, quercetin can also be found in healthy foods like red onion, apples, kale, blueberries and green tea.

3. Take anti-inflammatory supplements

The National Center for Complementary and Integrative Health (NCCIH) recommends the following supplements, which have a long history of use for treating inflammation and the pain associated with inflammation:

• Omega-3 fatty acids: Especially known for helping with the inflammation associated with rheumatoid arthritis. In general, omega-3 fatty acids have been shown in numerous studies to decrease system-wide inflammation, making them helpful to a wide range of health concerns.
• Turmeric: Turmeric is a spice that is also available in supplement form, and it contains a powerful component called curcumin, which is known for its anti-inflammatory ability.
• Willow bark: This herb comes from the willow tree and is traditionally used for pain and inflammatory conditions. It is commonly used for general pain, low back pain, osteoarthritis, bursitis and rheumatoid arthritis.
• Bromelain: Naturally found in pineapple, bromelain is an enzyme with an impressive ability to reduce swelling.
• Methylsulfonylmethane (MSM): MSM supplements can help rebuild the lining of the digestive tract and lower inflammatory responses in response to allergic reactions to certain foods.

Other anti-inflammatory supplements may include:

• Super greens
• Collagen
• Zinc
• Capsaicin
• Magnesium
• Vitamin B6
• Vitamin C
• Vitamin D
• Vitamin E
• Probiotics

4. Utilize anti-inflammatory practices

Exercise

Exercise is a key habit to practice regularly for optimal health and can help lower inflammation. A study published in the journal Brain, Behavior and Immunity found that even just 20 minutes of moderate exercise can decrease inflammatory responses and may protect against chronic conditions with low-grade inflammation.

Try to get in at least 150 minutes of moderate exercise per week, such as zone 2 cardio exercises.

Meditation

Daily practices like prayer and meditation can also help with your inflammatory response. One systematic review and meta-analysis demonstrated how a meditation practice can reduce psychological stress. Research also has pointed toward mind-body practices like meditation and tai chi as ways to dampen the activity of genes associated with inflammation.

Here are more anti-inflammatory lifestyle principles to incorporate:

• Don’t smoke
• Limit alcohol
• Maintain a healthy weight
• Manage stress

Frequently asked questions

What is inflammation?

It is the body’s natural immune response to injury, infection or irritation. It helps protect and heal tissues by increasing blood flow and activating immune cells. While short-term inflammation is essential for recovery, chronic inflammation can become harmful and contribute to long-term health issues.

What causes inflammation in the body?

It can be triggered by infections, injuries and toxins, but it is also influenced by lifestyle factors. Common contributors include a highly processed diet, excess sugar intake, chronic stress, poor sleep, smoking, environmental pollutants and lack of physical activity.

What is the difference between acute and chronic inflammation?

Acute inflammation is short-term and occurs in response to an immediate injury or illness, such as a cut or infection. Chronic inflammation is long-lasting and occurs when the immune system stays activated over time, even without a clear threat, which may increase the risk of disease.

What are the symptoms of inflammation?

Common signs include redness, swelling, warmth and pain. Chronic inflammation may also present as fatigue, joint stiffness, digestive discomfort, headaches, brain fog or recurring aches and pains.

Why is chronic inflammation bad for your health?

It can damage healthy cells, tissues and organs over time. It has been linked to conditions such as heart disease, type 2 diabetes, autoimmune disorders, arthritis, digestive issues and accelerated aging.

What foods cause inflammation?

Foods that may increase inflammation include refined carbohydrates, fried foods, sugary beverages, processed meats, excessive alcohol, and foods containing artificial additives or trans fats. These foods can disrupt blood sugar balance and promote inflammatory pathways in the body.

What foods help reduce inflammation?

Anti-inflammatory foods include fruits and vegetables rich in antioxidants; omega-3 foods like fatty fish, nuts and seeds; olive oil; herbs and spices’ and fiber-rich foods that support gut health. These foods help regulate immune responses and oxidative stress.

Can inflammation affect digestion and gut health?

Yes, chronic inflammation can damage the gut lining and disrupt the balance of beneficial bacteria. This may lead to digestive issues such as bloating, food sensitivities and irregular bowel movements, while also affecting immune and metabolic health.

How does stress affect inflammation?

Chronic stress increases cortisol and inflammatory markers in the body. Over time, this stress response can keep the immune system activated, contributing to systemic inflammation and increasing the risk of inflammatory-related conditions.

Does exercise reduce inflammation?

Regular, moderate exercise has been shown to help lower inflammation by improving circulation, insulin sensitivity and immune regulation. However, excessive or intense training without proper recovery may temporarily increase it.

How long does it take to reduce inflammation?

The timeline for reducing inflammation varies based on diet, lifestyle and overall health. Some people may notice improvements within days to weeks of making anti-inflammatory changes, while chronic inflammation may take longer to resolve.

Can supplements help reduce inflammation?

Certain supplements may support healthy inflammatory responses, including omega-3 fatty acids, turmeric, magnesium and probiotics. Supplements should complement, not replace, a nutrient-dense diet and healthy lifestyle.

Is inflammation always a bad thing?

No, it is a vital part of the body’s defense and healing process. Problems arise when it becomes chronic or excessive, which can lead to tissue damage and increased disease risk.

How do you naturally reduce inflammation?

Natural strategies include eating an anti-inflammatory diet, managing stress, getting adequate sleep, staying physically active, maintaining a healthy weight, and avoiding smoking and excessive alcohol.

Can inflammation be reversed?

In many cases, it can be reduced or managed by addressing underlying causes. Consistent lifestyle changes, including diet and stress management, can help restore balance and support long-term health.

When should you see a doctor?

If you experience persistent pain, swelling, fatigue or other unexplained symptoms that do not improve with lifestyle changes, it’s important to consult a healthcare provider to rule out underlying conditions.

What does inflammation in the body mean?

Inflammation in the body refers to the immune system’s protective response to perceived threats, such as injury, infection or toxins. This response helps the body heal and defend itself by activating immune cells and signaling pathways. However, when it persists long term, it can disrupt normal bodily functions and contribute to chronic disease.

What does inflammation feel like?

It may feel different depending on whether it is acute or chronic. Acute inflammation often causes redness, swelling, warmth and pain, while chronic inflammation may present as persistent fatigue, joint stiffness, muscle soreness, digestive discomfort, headaches or brain fog.

What is the root cause of inflammation?

The root cause is immune system activation in response to stressors. Chronic inflammation is often driven by ongoing triggers, such as poor diet, blood sugar imbalances, chronic stress, lack of sleep, environmental toxins, gut dysfunction or untreated infections.

How can I reduce inflammation in the body fast?

Reducing inflammation quickly involves removing inflammatory triggers and supporting the body’s natural healing processes. This includes eating whole, anti-inflammatory foods, staying hydrated, prioritizing sleep, managing stress, engaging in gentle movement, and avoiding sugar, alcohol and processed foods. Many people notice improvements within days when these strategies are implemented consistently.

Final thoughts

• Inflammation is a key aspect of the immune system’s response to injury and infection. Acute inflammation helps heal damaged tissue and defend itself against pathogens like viruses and bacteria.
• Problems arise when the inflammatory process goes on for too long and becomes chronic. Chronic inflammation is at the root of most diseases.
• If you’re wondering how to reduce inflammation in the body, eat anti-inflammatory foods, avoid inflammatory foods, add anti-inflammatory supplements to your routine, exercise regularly, meditate and manage stress.
