Understanding Inflammation and the Role of Nutrition

Inflammation occurs as our body responds to infection, toxins and injury. This inflammatory response is a blessing as it is a part of our immune system, a way to protect our body from harm and allow it to heal. Inflammatory cells and increased blood flow are sent to surround a damage or threat and keep it contained. This type of response is called acute inflammation which causes redness, pain, and swelling that’ll normally last a few hours or possibly days until the body is healed.

In chronic inflammation, however, this immune response can last for months or years and it is spread throughout the body. This response is no longer a good thing as chronic inflammation can lead to the damage of healthy cells, tissues and organs and is linked to the development of cancer, heart disease, metabolic syndrome, rheumatoid arthritis, type 2 diabetes, obesity, asthma and neurodegenerative diseases like Alzheimer’s disease. Dealing with chronic inflammation can be extremely uncomfortable with symptoms like body pain, joint pain, muscle pain, chronic fatigue, insomnia, depression, anxiety, mood disorders, constipation, diarrhea, reflux, weight gain or weight loss, and frequent infections. For some, the symptoms are milder and more manageable.

Chronic inflammation is the sign of an underlying problem. It may be caused by an auto-immune disorder (such as rheumatoid arthritis, lupus, type 1 diabetes, celiac disease, or multiple sclerosis) where the immune system misidentifies healthy tissues as a threat and launches an immune response. Alternatively, chronic inflammation may be caused by prolonged exposure to irritants like industrial chemicals or pollution and untreated infections or injury. Chronic inflammation may be diagnosed by looking at blood levels of C-reactive protein (CRP). This test won’t identify the cause of the inflammation, but will confirm its presence. ( With acute inflammation CRP blood levels may be greater than 3.5mg/L. One to three milligrams/liter (mg/L) of blood may signify chronic inflammation.)


Non-steroidal anti-inflammatory drugs (NSAIDs) are medications available over the counter and include aspirin, ibuprofen and naproxen. NSAIDs are effective in reducing inflammation and pain but there are complications associated with their prolonged use including risk of peptic ulcers, stroke, heart disease and kidney failure. Steroids are also used to treat inflammation, they work by suppressing the immune response that causes inflammation. This is beneficial in cases of allergies and autoimmune disease when the immune system is fighting against healthy cells. Long-term steroid use may lead to glaucoma, cataracts, high blood pressure,  high blood sugar, diabetes, infections, osteoporosis, severe fatigue, loss of appetite, nausea, muscle weakness, bruising, and slow wound healing. Supplements are also used to treat inflammation. Different supplements have been tested for specific inflammatory diseases and shown significant improvements on levels of inflammation.

Curcumin, found in turmeric, has been shown to reduce inflammation and improve arthritis symptoms. Studies testing the effects of curcumin supplementation on people with metabolic syndrome and cancerous tumors have also found a significant reduction in inflammation.

Fish oil is another supplement used in treating inflammation. The omega-3 fatty acids which contain eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been shown to reduce inflammation in people with higher than normal levels.

Food Modifications

An anti-inflammatory diet will not address the underlying cause of the inflammation but it may help to make symptoms more manageable while the cause is addressed with medical professionals.

  • Incorporating plant-based foods into your diet will automatically provide you with multiple anti-inflammatory nutrients including antioxidants and phytonutrients. Plants with stronger pigments generally have higher levels of antioxidants, so make sure to include fruits and vegetables of all colors to gain from the different antioxidants they contain.
  • Incorporate whole grains, nuts, seeds, soy-based proteins like tofu, legumes like beans, peas and lentils, herbs, and spices. Ginger, garlic and cayenne have been shown to help reduce chronic inflammation and components of black pepper have been found to be helpful in absorbing other anti-inflammatory compounds like curcumen found in turmeric.
  • Omega-3 fatty acids which are found in salmon and tuna, walnuts, and flaxseed have been shown to reduce inflammation and help with the pain that is associated with it. Cut back on foods high in saturated fat like red meat and processed foods, including those high in sugar and fried in fat, as they’ve been associated with higher levels of inflammation.

There are many diet plans out there that incorporate these elements and can be considered an anti-inflammatory diet. The Mediterranean Diet and the DASH diet are two such examples.

Other Lifestyle Factors

Other than diet there are additional lifestyle factors that affect inflammation. Regular physical activity of moderate intensity has anti-inflammatory effects. Sleep disturbances, excessive alcohol consumption, chronic stress, smoking and obesity all increase inflammation. By taking care to get adequate sleep, manage stress and maintain a healthy weight one may reduce inflammation.

Consider the Following

Chronic inflammation is a prolonged condition that can cause damage in the body.

  • Consulting with licensed healthcare workers is essential in managing chronic inflammation and treating the underlying cause.
  • Addressing chronic inflammation with diet has proven effective.
  • Incorporating a variety of plant-based foods while limiting heavily processed foods is helpful in reducing chronic inflammation.
