Inflammation’s Impact on Brain Function

It’s easy to recognize when your body is stiff and achy.  This usually means that inflammation has gotten out of control leading to pain.  Inflammation, in moderation, is normal.  It’s part of the healing process, for example, after an injury.  However, long-term chronic inflammation puts a huge strain on us and is far from ideal.  What you may not have considered is that the brain also experiences inflammation!  Brain inflammation impacts a number of crucial processes such as brain communication and circulation in the brain.  Healthy circulation carries nutrients throughout the body and brain. Poor brain circulation feels like your brain is in a fog, which makes it difficult to think clearly or make decisions because mental speed is slow.  It can be difficult to concentrate for very long because the brain is fatigued. 

Let’s take a look at healthy eating strategies to calm down, or modulate, a brain with inflammation. 
  • Grass-fed beef contains a healthier fat profile than grain-fed beef.  When cows eat grass they make omega-3 fat. Omega-3 fats modulate, while omega-6 fats increase, inflammation.  Grass-fed animals contain a 3:1 ratio of omega-6 to omega-3 fats.  Grain-fed animals can contain as high as 27:1 omega-6 to omega-3 fats. 
  • Salmon is a wonderful source of omega-3 fats.  Purchase wild caught rather than farm raised fish. 
  • Curry seasoning.  Curries contain a variety of spices and turmeric is common in these blends.  Spices are very nutrient dense and they make food so much more palatable!  The curry blends are known to support healthy inflammatory levels. 
  • Flavonoids are phytonutrients found in fruits and vegetables and they have antioxidant effects.  Berries contain high amounts of flavonoids and are considered one of the top foods to support brain health.  Also consider green and red vegetables such as peppers, broccoli, artichoke and celery for lutein.  Fresh spices such as parsley with apigenin, and thyme with luteolin, are flavonoids that dampen brain inflammation.  Chamomile also contains apigenin and is relaxing when steeped as a tea. 
  • Green tea contains high levels of catechins which support healthy blood flow in the brain.  Theanine in green tea is calming on the brain while still allowing the ability to concentrate and learn.  Green tea contains considerably less caffeine than coffee. 
  • Leafy green vegetables contain the flavonoids lutein and zeaxanthin.  Some options are kale, spinach, and collard greens.  To maximize nutrient absorption gently boil greens for three minutes until they are bright green, but not mushy.  Throw away the water.   
Incorporating these foods and spices into your weekly diet offers more than just brain support.  Some other reasons to eat them are for healthy detoxification, immune health and eye health.  Since it is difficult to get the necessary 8-10 servings of vegetables and fruit daily, you may want to consider one of the many greens drinks on the market.  They can be purchased in powdered form, so they don’t spoil like fresh food does, and they can be added to water, smoothies, or even food.

Many of the nutrients mentioned here are also available as supplements. 
  • Fish oil supplements with a high ratio of DHA to EPA. Brain cells need DHA. 
  • Curcumin is the active ingredient in turmeric.  The turmeric root contains about 5% curcumin. Supplements are typically standardized to contain 95% curcumin so they will be more effective than food sources at taming the fires of inflammation.  Take curcumin supplements on an empty stomach, or at the beginning of a meal, with a healthy fat (such as fish oil) to maximize absorption.  
  • Lutein and Zeaxanthin supplements are typically used for eye health, they are often together in blends, and they are needed in high concentration in the brain.  Take them with a meal containing healthy fat.
  • EGCG is a key property in green tea.  It plays a role in neuron formation, especially in the hippocampus which is involved in learning and memory.

Supplements contain higher amounts of these nutrients than food can.  Today’s environment, the quality of our food, and chronic illness are reasons to consider supplementing.  It may take more of a nutrient than what is available from food alone to correct long-term imbalances, and this includes mental illness.  Always follow the dosing instructions on supplement bottles or work with an integrative medical doctor, naturopathic doctor, nutrition therapist or functional chiropractor for individual recommendations.   If you are using prescription medicines, research whether diet or supplement changes will interfere with the medicine’s efficacy or your safety.
