Inflammation has been linked to a vast array of health concerns. Find out the answers to the question

what does inflammation mean

Inflammation is a response that has an important mission: to remove harmful substances---such as bacteria, damaged cells, a splinter, or other debris---from an injury and then to promote the healing process.

The word anti-inflammatory has practically become a household word. From herbs like turmeric and oregano to foods like berries and cruciferous vegetables, there are myriad selections that boast anti-inflammatory properties.

Following an anti-inflammatory diet or supplementing with anti-inflammatory substances has become more popular than ever. But what does inflammation mean in the first place? And is fighting inflammation really that important? Here, we address those important questions.

What Does Inflammation Mean: Normal Immune System Process

Inflammation is a normal part of the immune response. Think of the last time you scraped your skin, got a bug bite, or had a splinter you couldn’t get out. Chances are, the affected area got swollen and red, and even hot or painful. This is inflammation at work, and in cases of acute injury, it’s a good thing.

The inflammatory response is basically your immune system gathering defenses to the injured tissue, helping to protect and heal it; the goal of inflammation is to remove harmful substances from the injury, such as bacteria, damaged cells, a splinter, or other debris, and then to promote the healing process. This is done by increasing blood flow to the area, gathering immune cells, causing pain to stop you from using the injured tissue, and protecting the tissue in other ways.

Inflammation: A Double-Edged Sword

Inflammation is not all bad. In many cases, it is vital in keeping us safe; inflammation is necessary to heal from traumas, infections, burns, allergies, cuts, and more. But how, then, has inflammation gotten such a bad rap?

It may take a few days or even weeks, but after an acute injury, redness and swelling eventually subside as the inflammatory response turns off. This is the normal, healthy functioning of the immune system. It is not this acute inflammation that is a problem; issues arise when inflammation doesn’t go away, but becomes chronic and systemic.

Chronic, low-grade inflammation will slowly but surely cause damage in your body, and it can lead to long-term health issues. It is associated with a number of conditions and diseases. Heart disease, dementia, arthritis, irritable bowel disease, fatigue, obesity, and depression, among others, all seem to have an inflammatory component.[1-3]

What Contributes to Chronic Inflammation?

A variety of factors can promote chronic inflammation in the body. Diet is one of the major factors; some foods are pro-inflammatory, while others are anti-inflammatory and protective.

High sugar and high fat are two pro-inflammatory dietary components, while polyunsaturated fatty acids like omega-3s are anti-inflammatory.

Researchers believe that by changing your diet to a healthy pattern, you’ll be able to reduce chronic inflammation in your body.[1] Lack of sleep, not enough physical activity, and chronic stress are also believed to largely affect the level of inflammation in the body.[2]

Best Defense: Living an “Anti-Inflammatory” Lifestyle

If you want to protect yourself against a wide range of diseases, from heart disease to Alzheimer’s, keeping your body out of an inflamed state is key. You won’t notice low-grade inflammation now, but it will take a toll in the long run, so taking a proactive approach is important.

The following steps are an excellent start:

  • Eat plenty of fruits and vegetables, and avoid refined carbohydrates. Eat more kale and other cruciferous vegetables, whole grains, dark chocolate, and fish.
  • Exercise regularly.
  • Get plenty of sleep.
  • Use techniques like meditation or cognitive behavioral therapy to manage stress.
  • Take anti-inflammatory supplements, like turmeric or fish oil.
