The complexities of the human brain can leave both a scientist and layperson a tad awestruck. Research is beginning to elucidate the fascinating repercussions of inflammation in the brain.
What is inflammation?
Inflammation is a finely tuned biological defense system designed to maintain the body’s equilibrium. When the body perceives tissue damage or infection, it triggers inflammation as a protective response. A deep wound in the hand, for instance, causes the body to trigger acute inflammation in the area as a first aid measure.
The redness, swelling, pain, heat, and loss of function in the hand are five hallmark signs and symptoms of acute inflammation. Once the wound is cleaned and stitched, the hand will begin to heal and the body will turn off the inflammation response. But if this defense system becomes disregulated, inflammation can persist for months to years in the absence of an actual threat.
Chronic inflammation can be triggered by recurring episodes of acute inflammation, unresolved infections, exposure to harmful physical or chemical compounds, or genetic susceptibility. Advanced age and deficiencies in antioxidants, vitamins, and minerals can impair the body’s ability to resolve inflammation.
The sneaky thing about chronic inflammation is that it often goes unnoticed. Low-grade, systemic inflammation can be simmering unnoticed for years, and eventually target the brain and nervous system in a process known as neuroinflammation. Neuroinflammation can cause cognitive changes and increase the risk of diseases such as multiple sclerosis and Alzheimer’s.
Quelling chronic inflammation can improve your mental well-being today and preserve your cognitive function in the years to come.
The Western diet has been associated with intestinal hyperpermeability and low-grade systemic inflammation. Enjoy foods rich in flavanols (berries), healthy fats (fish), and whole grains.
Choose anti-inflammatory foods, like the following.
|cacao||has been shown to have an anti-inflammatory effect|
|fish||are rich in omega-3 fatty acids—a higher intake is associated with lower levels of the inflammatory marker C-reactive protein (CRP)|
|green tea||polyphenols in green and black tea are associated with a reduction in CRP|
|berries||antioxidants and polyphenols may protect against inflammation|
|olive oil||mitigates pro-inflammatory markers tumor necrosis factor (TNF) and interleukin-6 (IL-6)|
|broccoli sprouts||compound has been shown to attenuate obesity-related inflammation|
|whole grains||consumed regularly, have been shown to reduce systemic low-grade inflammation|
|beans||have been shown to reduce low-grade inflammation among those with cardiometabolic diseases|
|avocado||consumed once per day, is associated with a decrease in CRP|
|mushrooms||rich in anti-inflammatory polysaccharides, which may be helpful in diseases related to inflammation|
Always check with your health care practitioner before taking a new supplement, which may be contraindicated with your current health condition(s) or prescription(s), including OTC drugs. The following supplements may help reduce inflammation or support brain health:
- fish oil
- vitamin C
- vitamin D
- vitamin E
