At the risk of being repetitious, I just wanted to pass along some good information on keeping your brain intact while you are pursuing a life of healthy eating and regular exercise. That’s why you’re reading this blog, right?
The seven guidelines to reduce risk of Alzheimer’s disease are:
- Minimize your intake of saturated fats and trans fats. Saturated fat is found primarily in dairy products, meats, and certain oils (coconut and palm oils). Trans fats are found in many snack pastries and fried foods and are listed on labels as “partially hydrogenated oils.”
- Eat plant-based foods. Vegetables, legumes (beans, peas, and lentils), fruits, and whole grains should replace meats and dairy products as primary staples of the diet.
- Consume 15 milligrams of vitamin E, from foods, each day. Vitamin E should come from foods, rather than supplements. Healthful food sources of vitamin E include seeds, nuts, green leafy vegetables, and whole grains. Note: The RDA for vitamin E is 15 milligrams per day.
- Take a B12 supplement. A reliable source of B12, such as fortified foods or a supplement providing at least the recommended daily allowance (2.4 micrograms per day for adults), should be part of your daily diet. Note: Have your blood levels of vitamin B12 checked regularly as many factors, including age, impair absorption.
- Avoid vitamins with iron and copper. If using multivitamins, choose those without iron and copper, and consume iron supplements only when directed by your physician.
- Choose aluminum-free products. While aluminum’s role in Alzheimer’s disease remains a matter of investigation, those who desire to minimize their exposure can avoid the use of cookware, antacids, baking powder, or other products that contain aluminum.
- Exercise for 120 minutes each week. Include aerobic exercise in your routine, equivalent to 40 minutes of brisk walking, three times per week.
Other preventive measures, such as getting a minimum of seven hours of sleep each night and participating in 30 to 40 minutes of mental activity most days of the week, such as completing crossword puzzles, reading the newspaper, or learning a new language, can only help boost brain health.
Before you leave, just wanted to pass on a reminder about my Page – Important facts about your brain – and exercise benefits.
I love this infographic of the brain. Surprisingly, they left out one of the most impressive facts to me, namely, that the brain burns 20 to 25 percent of our daily calories. Bigger than any single muscle.
Before you go, please check out my Page – Important facts about your brain (and exercise benefits) for a lot more details on this major organ in our body.
In the nearly 10 years of writing this blog I have come to believe that use it or lose it is an unassailable law of the body. And what applies to the body often carries over to the brain. As I have mentioned previously, my family has dementia in general and Alzheimer’s in particular on both sides, so keeping a clear head really resonates with me.
Keeping physically and mentally active in middle age may be tied to a lower risk of developing dementia decades later, according to a study published in the medical journal Neurology. Mental activities included reading, playing instruments, singing in a choir, visiting concerts, gardening, doing needlework or attending religious services.
“These results indicate that these activities in middle age may play a role in preventing dementia in old age and preserving cognitive health,” said study author Jenna Najar, MD, from Sahlgrenska Academy, University of Gothenburg.
“It’s exciting as these are activities that people can incorporate into their lives pretty easily and without a lot of expense.” Continue reading
As a senior citizen whose family has Alzheimer’s and dementia on both sides I am keenly interested in anything on the subject. Herewith a study published in Nature Medicine.
Athletes know a vigorous workout can release a flood of endorphins: “feel-good” hormones that boost mood. Now there’s evidence that exercise produces another hormone that may improve memory and protect against Alzheimer’s disease, according to a study co-led by Ottavio Arancio, MD, PhD, a researcher at Columbia University’s Vagelos College of Physicians and Surgeons and Taub Institute for Research on Alzheimer’s Disease and the Aging Brain.
Physical activity is known to improve memory, and studies suggest it may also reduce the risk of Alzheimer’s disease. But researchers don’t understand why. Continue reading
This is one of those one picture is worth a thousand words posts. As a guy turning 79 in January, I feel like living proof of that. Get out and move that body. You don’t have to get hard core, you can walk. Walking is simple weight-bearing exercise that benefits your bones as well as your brains. Check out my Page – Why you should walk more to learn more.

More exercise was not always better, and the study found that exercising for 45 minutes three to five times a week was associated with the biggest benefits.
Riding a bike scored really high in the study
The study included all types of physical activity, ranging from childcare, housework, lawn-mowing and fishing to cycling, going to the gym, running and skiing.
Exercise reduces the risk of cardiovascular disease, stroke, diabetes, and mortality from all causes, but its association with mental health remains unclear.
Previous research into the effect of exercise on mental health has conflicting results. While some evidence suggests that exercise may improve mental health, the relationship could go both ways – for example inactivity could be a symptom of and contributor to poor mental health, and being active could be a sign of or contribute to resilience. The authors note that their study cannot confirm cause and effect.
Eat less; move more; live longer. The World Health Organization agrees. Following are the potential results of inadequate exercise for all age groups, according to the WHO.
– Insufficient physical activity is one of the leading risk factors for death worldwide.
– Insufficient physical activity is a key risk factor for noncommunicable diseases (NCDs) such as cardiovascular diseases, cancer and diabetes.
– Physical activity has significant health benefits and contributes to prevent NCDs.
– Globally, 1 in 4 adults is not active enough.
– More than 80% of the world’s adolescent population is insufficiently physically active.
– Policies to address insufficient physical activity are operational in 56% of WHO Member States.
WHO Member States have agreed to reduce insufficient physical activity by 10% by 2025.
What is physical activity?
WHO defines physical activity as any bodily movement produced by skeletal muscles that requires energy expenditure – including activities undertaken while working, playing, carrying out household chores, travelling, and engaging in recreational pursuits.
The term “physical activity” should not be confused with “exercise”, which is a subcategory of physical activity that is planned, structured, repetitive, and aims to improve or maintain one or more components of physical fitness. Beyond exercise, any other physical activity that is done during leisure time, for transport to get to and from places, or as part of a person’s work, has a health benefit. Further, both moderate- and vigorous-intensity physical activity improve health.
How much of physical activity is recommended? Continue reading
Eat less; move more; live longer
Check out my Page – Do you know the dangers of too much sitting? for more.
This is perfectly in line with our mantra of eat less; move more; live longer. Besides all the health benefits of exercise on the brain and body, Harvard Health Publishing says that it also reduces stress.
How does exercise reduce stress, and can exercise really be relaxing?
Rest and relaxation. It’s such a common expression that it has become a cliche. And although rest really can be relaxing, the pat phrase causes many men to overlook the fact that exercise can also be relaxing. It’s true for most forms of physical activity as well as for specific relaxation exercises.
Exercise is a form of physical stress. Can physical stress relieve mental stress? Alexander Pope thought so: “Strength of mind is exercise, not rest.” Plato agreed: “Exercise would cure a guilty conscience.” You’ll think so, too — if you learn to apply the physical stress of exercise in a controlled, graded fashion.
How exercise reduces stress
Aerobic exercise is key for your head, just as it is for your heart. You may not agree at first; indeed, the first steps are the hardest, and in the beginning, exercise will be more work than fun. But as you get into shape, you’ll begin to tolerate exercise, then enjoy it, and finally depend on it. Continue reading
I wanted to share this fine rundown of finding the gold in the golden years. As a dog lover I am a follower of Paul Handover’s Learning from Dogs blog. Clearly, this post covers ground most germaine to Diet, Exercise and Living Past 100.
Learning from Dogs
Living well as we age.
TIME magazine published a double-issue in February of this year How To Live Longer Better!
The article, on Page 47, opens:
Old age demands to be taken very seriously – and it usually gets its way!
Then later on in that same article one reads:
Exactly how much – or how little – exercise it takes to begin paying dividends has been one of the happy surprises of longevity research. A 2016 study found that elderly people who exercised for just 15 minutes a day, at an intensity level of a brisk walk, had a 22% lower risk of early death compared to people who did not exercise.
Then two sentences later:
Researchers from McMaster University in Canada even found that breaking a sweat for just 60 seconds may be long enough to improve health and fitness (as long as it’s a tough workout).

As I have said numerous times here, I love it when fresh news meets my bias. The one I am thinking about is how physical exercise benefits brain function. You can check out my post – Can exercise help me to learn? And, don’t forget my Page – Important facts about your brain – and exercise benefits.
If you want to learn to walk a tightrope, it’s a good idea to go for a short run after each practice session. That’s because a recent study in NeuroImage demonstrates that exercise performed immediately after practicing a new motor skill improves its long-term retention. More specifically, the research shows, for the first time, that as little as a single fifteen-minute bout of cardiovascular exercise increases brain connectivity and efficiency. It’s a discovery that could, in principle, accelerate recovery of motor skills in patients who have suffered a stroke or who face mobility problems following an injury. Continue reading
More good news on exercise this morning. Writing in the British Psychological Society Research Digest, Emma Young reports positive news on the move more section of our eat less; move more; live longer mantra.
Aerobic exercise – any activity that gets your heart pumping harder – improves mood, anxiety and memory. It can help people with major depressive disorder, bipolar disorder and anxiety disorder. Now there’s evidence, from a randomized controlled trial published in Frontiers in Psychiatry, that a program of regular aerobic exercise also reduces psychopathology in people diagnosed with schizophrenia. And it seems to have a particular impact on so-called “negative” symptoms, such as apathy and loss of emotional feeling, which are not improved by standard drug treatments.
“[W]hile antipsychotics [drug treatments] are essential in treating schizophrenia, interventions other than antipsychotic treatment…may be needed to achieve better outcomes,” write the authors of the new study, led by Peng-Wei Wang at Kaohsiung Medical University Hospital in Taiwan.

Eat less; move more; live longer remains the mantra of this blog. Herewith another example of the value of the move more element. We all want to live longer, but that has little meaning if we don’t have a fully functional brain to power us through. I talk about the value of exercise regularly here. Now we have a study that quantifies the amount of movement relevant to benefit our brain.
We know that exercise may help improve thinking skills. But how much exercise? And for how long?
To find the answers, researchers led by Joyce Gomes-Osman, Ph.D., PT, assistant professor of clinical physical therapy and neurology at the University of Miami Miller School of Medicine, reviewed all of the studies in which older adults were asked to exercise for at least four weeks and then take tests of thinking and memory skills. Their results were compared to those of people who did not start a new exercise routine. The review was published in the May 30 online issue of Neurology Clinical Practice, an official journal of the American Academy of Neurology.
The researchers found that people who exercised an average of at least 52 hours over about six months for about an hour each session may improve their thinking skills. In contrast, people who exercised for an average of 34 hours over the same time period did not show any improvement in their thinking skills. Continue reading
Groundbreaking research shows that neurological health depends as much on signals sent by the body’s large, leg muscles to the brain as it does on directives from the brain to the muscles. Published in Frontiers in Neuroscience, the study fundamentally alters brain and nervous system medicine—giving doctors new clues as to why patients with motor neuron disease, multiple sclerosis, spinal muscular atrophy and other neurological diseases often rapidly decline when their movement becomes limited.
“Our study supports the notion that people who are unable to do load-bearing exercises—such as patients who are bed-ridden, or even astronauts on extended travel—not only lose muscle mass, but their body chemistry is altered at the cellular level and even their nervous system is adversely impacted,” says Dr. Raffaella Adami from the Università degli Studi di Milano, Italy.

Here we have more good news on the exercise/brain front. Eat less; move more; live longer really works on all levels it seems.
Healthy older people who exercise regularly are less inclined to struggle to find words to express themselves, research led by the University of Birmingham has discovered.
Researchers found that older adults’ aerobic fitness levels are directly related to the incidence of age-related language failures such as ‘tip-of-the-tongue’ states.
The research, published in Scientific Reports, is the first of its kind to investigate the relationship between aerobic fitness levels and temporary cognitive lapses, such as not having a word come to mind when speaking – known as a ‘tip-of-the-tongue’ state.
People in a tip-of-the-tongue state have a strong conviction that they know a word, but are unable to produce it, and this phenomena occurs more frequently as we grow older. Continue reading
Herewith another log on the fire. Eat less; move more; live longer remains the mantra here. I was aware of the brain benefits of aerobic exercise, now, it seems that strength training also contributes.
A study of nearly half a million people has revealed that muscular strength, measured by hand grip, is an indication of how healthy our brains are.
Dr. Joseph Firth, an Honorary Research Fellow at The University of Manchester and Research Fellow at NICM Health Research Institute at Western Sydney University, crunched the numbers using UK Biobank data.
Using data from the 475,397 participants from all around the U.K., the new study showed that on average, stronger people performed better across every test of brain functioning used. Continue reading
