I have spent a lot of time writing about the benefits of exercise for the brain as well as the body. Herewith info from the Tufts Health and Nutrition Letter on food for thought.
Currently available medical treatments for age-related cognitive decline and Alzheimer’s disease have had limited success. Adopting a healthy diet and lifestyle has been among the most consistent recommendations to maintain brain health over the long term. Some studies have linked an overall healthy dietary pattern to less chance of experiencing age-related decline in memory and other cognitive skills.
The specifics of “brain protective” diets vary, but tend to have certain elements in common. Dietary patterns associated with lower risk of age-related cognitive decline and dementia are higher in non-starchy vegetables, fruits, whole grains, nuts, legumes and seafood while limited in red and/or processed meats, sugar-sweetened foods and drinks, refined grains and added salt.
But there have been few long-term trials testing overall dietary patterns for protecting the aging brain. Researchers at Rush University Medical Center in Chicago and the Harvard T.H. Chan School of Public Health are currently conducting a clinical trial of a diet specifically optimized for brain health and mild weight loss—the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet.
If successful, the result of the MIND trial will provide older adults with more specific nutritional guidance to maintain their cognitive health. “What they’re doing is logical and I predict will have positive benefits for a disease for which we have few interventions,” notes Dennis Steindler, PhD, senior scientist and director of Tufts’ HNRCA Neuroscience and Aging Laboratory. “Past trials were not home runs, but this study could be it if it bears the kind of findings I think it will.” Continue reading
I don’t know if these really will increase your brain power, but I don’t see any harm in letting you know about them.
Please let me know if you have any experience with these.To my knowledge they are all excellent foods nutritionally.
In a scientific first, researchers have observed in mice how the brain learns to repeat patterns of neural activity that elicit the all-important feel-good sensation. Until today, the brain mechanisms that guide this type of learning had not been measured directly, according to Neuroscience News.
This research offers key insights into how brain activity is shaped and refined as animals learn to repeat behaviors that evoke a feeling of pleasure. The findings also point to new strategies for targeting disorders characterized by abnormal repetitive behaviors, such as addiction and obsessive-compulsive disorder, or OCD.
This image is an artistic interpretation of the authors’ work. Within a myriad of many pixel-like neurons, an obvious pattern emerges from more active red pixels and from parallel, less-active blue pixels: the letters corresponding to the word reward.

The study, led by researchers at Columbia University’s Zuckerman Institute, the Champalimaud Centre for the Unknown and the University of California at Berkeley (UC Berkeley), was published in Science.
“It’s no secret that we derive pleasure from doing things we enjoy, such as playing our favorite video game,” said Rui Costa, DVM, PhD, senior author and the associate director and CEO of Columbia’s Zuckerman Institute. “These results reveal that the brain learns which activity patterns lead to feel-good sensations, and reshapes itself to more efficiently reproduce those patterns.” Continue reading
I must confess I am late to the party in terms of raw cacao. That is strange as I love chocolate and don’t need much of an excuse to eat some. But, I actually came across raw cacao in one of the recent infographics on super foods that I ran right here on the blog. Turns out raw cacao is one of them. I bought mine from Terrasoul Superfoods on Amazon.
Secrets of Longevity says, “It turns out that all the bad things commonly attributed to non-raw chocolate bars, such as cavities, weight gain and diabetes, are actually caused by the dairy, sugar and others fillers added to the dark chocolate. Health benefits of chocolate when it is in the form of raw cacao beans, butter, nibs and/or the powder include; weight loss (because of its high chromium and coumarin content), prevention of cavities (theobromine actually kills streptococci mutans one of the strains of bacteria that cause tooth decay) and regulation of blood sugar which is beneficial for diabetes (chromium can naturally regulate blood sugar). Also raw cacao benefits the heart and the entire cardiovascular system as a whole.
“Cacao is the highest whole food source of magnesium, which also happens to be the most deficient mineral in the diet of modern cultures. Magnesium relaxes muscles, improves peristalsis in the bowels and relaxes the heart and cardiovascular system. The dark chocolate antioxidants have been clinically proven to literally dissolve plaque built up in the arteries which helps in reversing heart disease and causes naturally lower blood pressure. Also, various other vitamins and minerals in raw cacao benefits the cardiovascular system.”
Now that you appetite has been whetted, how do you get this bitter, if wonderful, substance into your system? Here is a brief list: Continue reading
Once again we have it demonstrated that diet and exercise prove beneficial even to seniors suffering from diabetes, according to HealthyinAging.org.
Type 2 diabetes affects blood circulation. The disease stiffens blood vessels and reduces the amount of oxygen that circulates throughout your body. This includes your brain. When blood flow in the brain is impaired, it can affect the way we think and make decisions.
People who have type 2 diabetes are often overweight or obese. These are conditions that may also be linked to cognitive problems (problems with thinking abilities). Lowering calorie intake and increasing physical activity are known to reduce the negative effects of type 2 diabetes on the body. However, the effects of these interventions on cognition and the brain are not clear.
Recently, researchers examined information from a 10-year-long study called Action for Health in Diabetes (Look AHEAD). In this study, participants learned how to adopt healthy, long-term behavior changes. In their new study, the researchers focused on whether participants with type 2 diabetes who lowered calories in their diet and increased physical activity had better blood flow to the brain. The researchers published their findings in the Journal of the American Geriatrics Society. Continue reading
Here is some heartening news for folks worried about fats consumption.
You may want to think about adding avocados, olive oil, and nuts to your grocery list, since a new study has suggested that the monounsaturated fatty acids in these foods could boost intelligence.
Researchers from the University of Illinois at Urbana-Champaign found that higher levels of monounsaturated fatty acids (MUFAs) in the blood correlated with greater general intelligence in older adults.
Study leader Aron K. Barbey, a professor of psychology at the university, and colleagues recently reported their results in the journal Neuroimage.
Experts in aging and Alzheimer’s disease are conducting a national clinical study to determine if exercise may be an effective non-drug intervention for maintaining cognitive fitness.
The Rush Alzheimer’s Disease Center at Rush University Medical Center is the only site in Illinois, and one of only 15 sites across the United States leading the Exercise in Adults With Mild Memory Problems (EXERT) study, which is trying to determine if exercise can slow the progress of memory loss and cognitive impairment in older adults.
Neuroscientists are collaborating with the YMCA to provide individualized, one-on-one exercise programs and personal training to study participants. Rush will be working with the McGaw YMCA in Evanston, Illinois, to provide 45-minute personal training sessions for one year.
Adults with memory issues may avoid being active when they need it most
“We want to see if a personalized program implemented in the community and prescribed by health care providers can be an effective therapy for people with memory issues,” said Dr. Neelum Aggarwal, associate professor of neurology and principal investigator of the EXERT study at Rush.

An apple a day keeps the doctor away – I always liked that one. While apples boast many health benefits, they do not, sadly, bulletproof us against all diseases.
“Everything our parents said was good is bad,” complains Alvy Singer, the character played by Woody Allen in “Annie Hall,” his 1977 Oscar-winning romantic comedy.
That’s a bit of an exaggeration, but when it comes to what certain foods can do to or for you, it’s probably best to take motherly advice, familiar sayings and other bits of conventional wisdom with a grain of salt.
“There’s some validity to some of them, but many of them are just old wives’ tales or myths that have trickled down over the years,” said Annette Frain, a registered dietitian at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina. Continue reading
I have written about the benefits of Vitamin D a number of times. You can check some of the links at the end of this post to read further. Now comes Neuroscience News with a report on its possible impact on increased longevity.
Research in C. elegans shows the popular supplement engages longevity genes to increase lifespan and prevent the accumulation of toxic proteins linked to many age-related diseases.
A simple Google search for “what does vitamin D do?” highlights the widely used dietary supplement’s role in regulating calcium absorption and promoting bone growth. But now it appears that vitamin D has much wider effects — at least in the nematode worm, C. elegans. Research at the Buck Institute shows that vitamin D works through genes known to influence longevity and impacts processes associated with many human age-related diseases. The study, published in Cell Reports, may explain why vitamin D deficiency has been linked to breast, colon and prostate cancer, as well as obesity, heart disease and depression.
“Vitamin D engaged with known longevity genes – it extended median lifespan by 33 percent and slowed the aging-related misfolding of hundreds of proteins in the worm,” said Gordon Lithgow, PhD, senior author and Buck Institute professor. “Our findings provide a real connection between aging and disease and give clinicians and other researchers an opportunity to look at vitamin D in a much larger context.” Continue reading
One of the aspects of living a long and healthy life that goes without saying is that our mind is fully functional. No one wants to life a long life if he is simply drooling into his oatmeal.
What I love about this infographic is that the first thing it mentions is – Exercise. I felt so strongly about this aspect of living that I created a Page on it – Important facts about your brain – (and exercise benefits).

For decades, scientists have viewed food as fuel, but the latest research suggests what you eat impacts your brain, too. In fact, study after study suggests adding certain foods to your plate can sharpen your mind, build new brain cells and may even help you remember where you left your keys.
With that in mind (pun intended), researchers at Rush University in Chicago developed the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet, which is basically a combination of the DASH diet and Mediterranean diet. The main difference: MIND stresses the importance of brain-boosting power foods, including nuts, berries and fatty fish. And research shows it’s remarkably effective.
According to the study published in Alzheimer’s & Dementia, seniors who closely followed the MIND diet slashed their risk of developing Alzheimer’s disease by a whopping 53 percent. Even those who only did a…

They found that the longer a patient had the disease, the more brain volume loss occurred, particularly in the gray matter. Gray matter includes areas of the brain involved in muscle control, seeing and hearing, memory, emotions, speech, decision-making and self-control.
Cooking with Kathy Man
Loss of gray matter can lead to dementia, experts say.
People with type 2 diabetes may lose more brain volume than is expected as they age, new research indicates.
Surprisingly, this shrinkage doesn’t appear to be linked to the damaging effect of diabetes on tiny blood vessels in the brain, but instead by how the brain handles excess sugar, the researchers noted.
“We have known for a long time that diabetes is not good for the brain,” said lead researcher Dr. R. Nick Bryan, a professor of radiology at the University of Pennsylvania’s Perleman School of Medicine in Philadelphia.
Diabetes is associated with an increased risk for stroke and dementia, he said. Until now, doctors have thought these risks were likely related to blood vessel damage related to diabetes.
“But our study suggests that there is additional damage to the brain which may be more like a brain disorder such…

I tried coconut oil for the first time back in April and I wrote Why should I try coconut oil? enumerating facts about how endurance athletes (bike riders like me) use it as a high energy food; how it helps to boosts our HDL cholesterol (the good cholesterol) readings, it has healing properties, etc.
Now comes a write up by Dr. Mercola about how coconut oil appears to be the perfect brain food.
As I have mentioned in previous posts, I lost an aunt to Alzheimer’s and my mother suffered from dementia in her final years. The possibility that coconut oil could be a positive influence on the brain resonated powerfully with me.
The following is from Dr. Mercola: “There are only two types of fuel your body can convert into energy: carbs/sugar, or fat. Again, ketones are what your body produces when it converts fat (as opposed to glucose) into energy. And a primary source of ketone bodies are the medium-chain triglycerides (MCT) found in coconut oil. In fact, coconut oil contains about 66 percent MCTs. Continue reading
Possibly one of the oldest and most widespread cooking cliches is the fish are brain food. I can still hear my mother telling me to eat my fish “it’s good for your brain.” Well, guess what. It’s true.
WebMD says, “Fish really is brain food. A protein source associated with a great brain boost is fish — rich in omega 3 fatty acids, essential for brain function and development. These healthy fats have amazing brain power: higher dietary omega 3 fatty acids are linked to lower dementia and stroke risks; slower mental decline; and may play a vital role in enhancing memory, especially as we get older.
“For brain and heart health, eat two servings of fish weekly.”
As a senior citizen and one who has dementia in his family, I was especially gratified to learn this.
In addition to eating fish, remember that cardiovascular exercise also benefits the brain directly because it sends oxygen molecules to the brain and creates new neurotransmitters.
