Eight nutrients to protect the brain

Brain health is the second most important component in maintaining a healthy lifestyle according to a 2014 AARP study. As people age they can experience a range of cognitive issues from decreased critical thinking to dementia and Alzheimer’s disease. In the March issue of Food Technology published by the Institute of Food Technologists (IFT), contributing editor Linda Milo Ohr writes about eight nutrients that may help keep your brain in good shape.

1. Cocoa Flavanols: Cocoa flavanols have been linked to improved circulation and heart health, and preliminary research shows a possible connection to memory improvement as well. A study showed cocoa flavanols may improve the function of a specific part of the brain called the dentate gyrus, which is associated with age-related memory (Brickman, 2014).

2. Omega-3 Fatty Acids: Omega-3 fatty acids have long been shown to contribute to good heart health are now playing a role in cognitive health as well. A study on mice found that omega-3 polyunsaturated fatty acid supplementation appeared to result in better object recognition memory, spatial and localizatory memory (memories that can be consciously recalled such as facts and knowledge), and adverse response retention (Cutuli, 2014). Foods rich in omega-3s include salmon, flaxseed oil, and chia seeds.

3. Phosphatidylserine and Phosphatidic Acid: Two pilot studies showed that a combination of phosphatidylserine and phosphatidic acid can help benefit memory, mood, and cognitive function in the elderly (Lonza, 2014).

4. Walnuts: A diet supplemented with walnuts may have a beneficial effect in reducing the risk, delaying the onset, or slowing the progression of Alzheimer’s disease in mice (Muthaiyah, 2014).

5. Citicoline: Citicoline is a natural substance found in the body’s cells and helps in the development of brain tissue, which helps regulate memory and cognitive function, enhances communication between neurons, and protects neural structures from free radical damage. Clinical trials have shown citicoline supplements may help maintain normal cognitive function with aging and protect the brain from free radical damage. (Kyowa Hakko USA).

6. Choline: Choline, which is associated with liver health and women’s health, also helps with the communication systems for cells within the brain and the rest of the body. Choline may also support the brain during aging and help prevent changes in brain chemistry that result in cognitive decline and failure. A major source of choline in the diet are eggs.

7. Magnesium: Magnesium supplements are often recommended for those who experienced serious concussions. Magnesium-rich foods include avocado, soy beans, bananas and dark chocolate.

8. Blueberries: Blueberries are known to have antioxidant and anti-inflammatory activity because they boast a high concentration of anthocyanins, a flavonoid that enhances the health-promoting quality of foods. Moderate blueberry consumption could offer neurocognitive benefits such as increased neural signaling in the brain centers.

Dr. Court’s Comments:

This is a great list. I’d encourage people to consider adding some, if not all, of these to their diet. However, these alone will not be 100% protective. To get much closer to that elusive 100% mark, exercise must be included. The benefits of exercise on the brain are numerous. Exercise is inherently anti-inflammatory. It improves fuel delivery as well as waste removal in the brain. It increases neural feedback which preserves synaptic connections. Remember this fact; 90% of the information coming into the brain on a daily basis is from proprioception. That is, 90% of the information is from our muscles and our joints. A sedentary lifestyle reduces this flow of information, reducing the survivability of neurons in the central nervous system. Exercise also keeps the heart healthy, and a healthy heart means a healthy brain.

Gait Related to Cognitive Decline

A new study furthers the evidence that our motor system (the system that controls our movements) is related to higher centers of brain function that control how we think, remember and interact with the world.  This study examines the link between how we walk and the risk for developing dementia. Check it out below!

Coffee Wards Off Dementia!

In a new study published in the Journal of Alzheimer’s Disease participants with mild cognitive impairment who had a certain level of caffeine in their blood did not go on to develop dementia.  This is the first study to attempt to isolate whether it’s just coffee that’s protective in dementia or if it is indeed the caffeine that imparts the benefit. In this case, the caffeine seems to be the protective variable.  See the video below for more.

Reducing Your Risk of Alzheimer’s Disease Naturally

As of next year the first of the baby boomers will reach 65 years old and by 2029 all of them will be at least 65.  This is significant because as we age certain diseases become more and more prominent.  One of them is Alzheimer’s disease.  This disease robs people of the faculties much too soon and causes heartache and financial hardship for families across the US.

Just How Big Is The Problem?

About 24 million people worldwide are known to be affected with dementia. This number is expected to balloon to 84 million by the year 2040.  These numbers include all forms of dementia, but up to 80% of dementia is caused by Alzheimer’s disease (AD).  In the US alone 5.3 million American’s have Alzheimer’s Disease and 96% of them are over the age of 65.  In just five years the number of Americans with Alzheimer’s will jump to 7.7 million and by 2050 the number is projected to more than double to 16 million.  The numbers truly are staggering.  As a matter of fact, AD has recently passed diabetes, yes diabetes, as the 6th most common cause of death in the US.  As our population continues to grow older because people are living longer, the problem is likely to get worse.  Current statistics show that just over 50% of people who are over 85 will go on to develop AD.

AD is also a very expensive problem for the United States.  In 2005, total Medicare spending was $91 billion and the total US cost was $172 billion for AD.  AD patients make up roughly 13% of Medicare enrollees but account for more than 1/3 of its spending.  The problem will only grow as our population ages.

So What Can I Do To Reduce My Risk?

The best way to treat AD is to prevent it in the first place.  There is very good research behind several nutritional supplements that can significantly reduce your risk of developing dementia as you age.

Vitamin E

Here’s what one study found on vitamin E:

“Among MCI-AD patients, the longitudinal decrease in cellular vitamin E was associated with the deterioration in cognitive performance. These results suggest that accumulation of oxidative damage may start in pre-symptomatic phases of AD pathology and that progression to AD might be related to depletion of antioxidant defenses.”

-J Alzheimers Dis. 2010 Aug 6.

So what does that mean.  Basically what this study found was that among patients who has mild cognitive impairment (MCI) or AD, people with the lowest levels of vitamin E had poorest performance on mental testing.  Oxidative damage is the process by which our brain tissue is broken down in AD.  Vitamin E helps fight this process.

Another study concluded:

“In conclusion, high plasma levels of vitamin E are associated with a reduced risk of AD in advanced age. The neuroprotective effect of vitamin E seems to be related to the combination of different forms, rather than to alpha-tocopherol alone.”

-J Alzheimers Dis. 2010;20(4):1029-37.

This is saying that higher levels of vitamin E in the blood were associated with a significant reduction in AD with advanced age.  It also says that when taking vitamin E you should be taking a combination of forms, not a singular type.  When you look at the back of your vitamin E supplement be sure that it says ‘mixed tocopherols.”  That will provide you with the most benefit.

Vitamin D

Vitamin D is the supplement of the hour right now.  It is being studied by everyone and just about everyone has found that it is critically important for overall health.  New research also shows it helps prevent AD.

“Vitamin D insufficiency and deficiency was associated with all-cause dementia, Alzheimer disease, stroke (with and without dementia symptoms), and MRI indicators of cerebrovascular disease. These findings suggest a potential vasculoprotective role of vitamin D.”

-Neurology. 2010 Jan 5;74(1):18-26. Epub 2009 Nov 25

This study is telling us that vitamin D insufficiency and deficiency was associated with higher risk for dementia and AD.  What this means is that even having levels that are slightly decreased (insufficiency) are associated with higher risk.  Keeping vitamin D levels up not only is important for bone health, cancer reduction and fall prevention but also reduces your risk of AD.  Pretty amazing stuff.

Another study on vitamin D found that:

“Clinical data suggest that vitamin D insufficiency is associated with an increased risk of several CNS diseases, including multiple sclerosis, Alzheimer’s and Parkinson’s disease, seasonal affective disorder and schizophrenia.  Overall, imbalances in the calcipherol system appear to cause abnormal function, including premature aging, of the CNS.”

– Psychoneuroendocrinology. 2009 Dec;34 Suppl 1:S278-86

This study is particularly interesting in that it shows that low vitamin D levels are associated with an increased risk of several CNS or central nervous system diseases including AD.  It also concluded that imbalances in the calcipherol, or vitamin D, system causes premature aging of the brain and central nervous system.  Why is this problematic?  Remember, the number one risk factor for AD is aging.  If we can slow this process, particularly in the brain, we can slow the onset of AD.  Vitamin D can do this for you.

Omega-3 Fatty Acids (Fish Oil)

“A plethora of in vitro, animal model, and human data, gathered over the past decade, highlight the important role DHA may play in the development of a variety of neurological and psychiatric disorders, including AD. Cross sectional and prospective cohort data have demonstrated that reduced dietary intake or low brain levels of DHA are associated with accelerated cognitive decline or the development of incipient dementia, including AD.”

-Clin Interv Aging. 2010 Apr 7;5:45-61.

DHA is a particular form of omega-3 fatty acid or fish oil.  This study concluded that low intake of this particular fatty acid or low brain levels of it are associated with cognitive decline and accelerated development of AD.  This is of particular interest because of all of the wonderful other benefits that omega-3’s give us.  You can prevent or reduce the risk of many other diseases simply by supplementing with fish oil.

There was this study as well:

“Plasma DHA was associated with slower decline on BVRT (Benton Visual Retention Test) performances in ApoE-epsilon4 carriers only. EPA and DHA may contribute to delaying decline in visual working memory in ApoE-epsilon4 carriers.”

-Neurobiol Aging. 2010 Jun 4.

This study was done on people who have the gene that is linked to an increased risk of AD.  What it concluded was very exciting.  Basically it found that the higher the omega-3 DHA was in the plasma the slower the decline in memory in people that were genetically predisposed to getting AD.  That’s wonderful news!  Many people think that their genetics are their destiny, but this study showed otherwise.

In Summary

This is just the tip of the iceberg in terms of research that is available on how to combat and reduce your risk of developing AD.  What we did not touch on in this article is that keeping your heart healthy and controlling your blood sugar is of utmost importance.  Do those things and take the supplements listed above and you can significantly reduce your risk of Alzheimer’s disease.

How to protect your brain – ward off dementia with these simple steps

Well it’s been some time since I have been able to post here on our blog.  The fourth of July holiday and some time away from the office kept me from posting the latest in health information for you.  However, I am back with new information regarding dementia.

Dementia is a scary disease that affects millions of Americans and the numbers are expected to sky rocket as the baby boomer generation approaches retirement age.  Dementia robs people of their faculties long before their time.  It can go on for many years and cause heartbreak and hardship for family members.  It is eventually fatal, but it is a long, slow process that destroys lives and relationships along the way.

For years it was thought that genetics played the most important role in determining who developed dementia and who did not.  It was almost a role of the dice, or so was thought.  In the last 5 years research has been mounting that dietary supplements and exercise can significantly reduce the risk of developing dementia.  A new study just released confirms some of those findings.

In a recent study people who exercised, regularly consumed tea and had the highest levels of vitamin D had the lowest risk of developing dementia.  This truly is great news.  There is something you can do to significantly reduce your risk of developing this disease.

Exercise

The first piece of this equation is about exercise.  Exercise has been shown to improve almost every single factor related to health that has been studied.  If you are not exercising, you are not truly taking care of yourself.  With respect to dementia, researchers looked at participants from the Framingham cardiovascular study.  They looked at 1,200 elderly people over 20 years, 242 of whom developed dementia.  They found that participants who had moderate to heavy levels of physical activity had about a 40% lower risk of developing any type of dementia. Those who reported the least amount of activity were 45% more likely to develop dementia compared with those who had higher levels of activity.

Regular Consumption of Tea

In a second study, including data on more than 4,800 men and women ages 65 and older, participants were followed for up to 14 years. Tea drinkers had less mental decline than non-tea drinkers. Those who drank tea one to four times a week had average annual rates of decline 37% lower than people who didn’t drink tea.  The results did not appear to be related to caffeine, however, because coffee drinkers did not see the same benefit except in people who drank coffee heavily (and that has it’s own problems).  Some teas, like green tea, are loaded with antioxidants and that is likely the mechanism of this protection.

Vitamin D

In a third study, British researchers looked at vitamin D’s effect on brain health. They examined data from 3,325 U.S. adults ages 65 and older from the NHANES III study. Vitamin D levels were measured by blood test, and cognitive tests were administered. Odds of cognitive impairment were about 42% higher in those deficient in vitamin D, and 394% higher in people severely deficient.  The research continues to mount on vitamin D.  It truly is amazing just how potent a weapon vitamin D is.  It is also clear to me that the current medical recommendations are far too low and that current sun safety guidelines are actually creating a society of people that are deficient in this life saving nutrient.

The benefit of these three things do not change your genetic make up.  They change the expression of those genes.  This is the study of epigenetics.  Essentially, each gene has a switch on it – an epigene.  These determine which genes get switched on and which do not.  Exercise, the antioxidants from tea and vitamin D seem to have a favorable affect on the epigenes.  They keep the bad genes turned ‘off’ and the good ones turned ‘on.’

Recommendations

Exercise at least three times per week.  Exercise should include weight training and cardiovascular work done in interval style training.  Exercise improves blood flow to the brain, reduces inflammation, increases necessary feed back to the brain and improves the efficiency of many metabolic pathways.  For more information visit www.bendearman.com.  Ben is a trainer that I work with and he’s got a great handle on how to exercise properly.

Take EGCG.  EGCG is the extract from green tea.  It has been studied rigorously and has been shown to be neuroprotective.  I recommend at least 500mg per day.  If you decide to start it please consult someone trained in functional medicine so they can provide you with a quality supplement.

Take vitamin D.  I have many blogs on my site that discuss the huge benefits of vitamin D.  If you’d like to read more about it please click vitamin D in our word cloud to the right or simply type it into our search feature.  It should be taken daily by just about everyone.  I recommend that people take anywhere from 2,000-4,000 IUs per day for maintenance.  Individually one may need even more depending on your condition.  It should be monitored with blood tests and you should shoot for a level no lower than 55 ng/ml.  Just about everyone will require supplementation to reach that level.
