This is fascinating and seems to bolster my thought that exercising the body benefits the brain a great deal. The concept of use it or lose it is widely known and accepted regarding physical development. It seems it also applies to mental makeup. As above, so below.
Research by a team of Vanderbilt University Medical Center (VUMC) scientists suggests that older people whose hearts pump less blood have blood flow reductions in the temporal lobe regions of the brain, where Alzheimer’s pathology begins.
The brain, which accounts for only 2 percent of total body weight, typically receives 12 percent of blood flow from the heart — a level maintained by complex, automatic processes, which maintain consistent blood flow to the brain at all times.
Angela Jefferson, Ph.D., director of the Vanderbilt Memory and Alzheimer’s Center, and colleagues investigated whether lower cardiac index (the amount of blood flowing out of the heart adjusted for body size) correlated with lower blood flow to the brain.
The purpose of the study was to better understand whether reductions in brain blood flow might explain clinical observations in prior research that have linked heart function to cognitive impairment, Alzheimer’s disease and dementia.
“We currently know a lot about how to prevent and medically manage many forms of heart disease, but we do not yet know how to prevent or treat Alzheimer’s disease,” Jefferson said. Continue reading
Eat less; move more; live longer remains the mantra of this blog. Now, according to the American Heart Association, the sooner you start, the better.
People with no major heart disease risk factors in middle age live longer and stay healthy far longer than others, according to a 40-year study reported in the American Heart Association’s journal Circulation.
“Good cardiovascular health in middle age delays the onset of many types of disease so that people live longer and spend a much smaller proportion of their lives with chronic illness,” said Norrina Allen, Ph.D., M.P.H., assistant professor of preventive medicine at Northwestern University Feinberg School of Medicine in Chicago.
In the first study to analyze the impact of cardiovascular health in middle age on the duration of illness later in life, researchers examined data from the Chicago Health Association study, which did initial health assessments in the late 1960s/early 1970s and has followed participants on an ongoing basis using Medicare health records. Researchers determined how many participants had favorable factors: non-smokers, free of diabetes and normal weight, blood pressure, and cholesterol levels; versus those with elevated risk factors or high risk factors.

Happy Valentine’s Day to one and all from me and Wondy.
Be good to your heart today … and every day!
The banana is one of the most amazing fruits there is. I was driving in my car one day listening to public radio. There was a fellow being interviewed who had just written a book on the history of the banana. I laughed. What kind of history could it have? Well, it turned out to be so fascinating that I ended up buying the book.
I like this needs overview of the organic machine in which each of us lives. It’s no accident that exercise figures in each of the segments.

I remember the old cliche when it rains, it pours referring to bad news, but, in fact, the past few days, it seems to have been raining stories on brain development. I think that is great news. This latest one is from the American Heart Association.
A healthy heart may have major benefits for preventing the decline in brain function that sometimes accompanies aging, according to new research in the Journal of the American Heart Association.
Researchers studied a racially diverse group of older adults and found that having more ideal cardiovascular health factors was associated with better brain processing speed at the study’s start and less cognitive decline approximately six years later. Continue reading
I have written about the dangers of prolonged sitting before and I think it is a message that can’t be repeated too often.
You can read further details on this by checking out my Page – Do You Know the Dangers of Too Much Sitting?
I read that the new Apple Watch will have an alert that reminds you that you have been sitting too long. We will know more when the Watch comes out.
“Mushrooms are miniature pharmaceutical factories, and of the thousands of mushroom species in nature, our ancestors and modern scientists have identified several dozen that have a unique combination of talents that improve our health,” says leading mushroom research, Paul Stamets, who has written six books about mushrooms.
Our Better Health
Diana Herrington February 10, 2015
If you’re looking for a new food to boost your health and shake up your boring meal routine, mushrooms might be it. With over 100 thousand species of mushroom-forming fungi and huge health benefits, the mushroom is a little-known superstar. We often sprinkle mushrooms on our salads or add them to our casseroles. Next time add a few more handfuls of this ingredient–or, better yet, make it the main entree! Including a little more mushroom to your favorite meal is a tasty and rewarding move.
- 140,000 species of mushroom-forming fungi.
- Close to 100 types of mushrooms being studied for their health benefits.
- A small number found to be very beneficial for boosting your immune system.

Commenting on the results, Dr Murray, who worked on all three studies, said: “There have been a great many findings demonstrating a role for nitrate in reducing blood pressure and regulating the body’s metabolism. These studies represent three further ways in which simple changes in the diet can modify people’s risk of type 2 diabetes and obesity as well as potentially alleviating symptoms of existing cardiovascular conditions to achieve an overall healthier life.”

Green veg contains nitrate could improve heart’s efficiency, blood supply to organs and reduce risk of diabetes and obesity
In three independent studies, scientists from the Universities of Southampton and Cambridge have identified how a simple chemical called nitrate, found in leafy green vegetables, can help thin blood ensuring oxygen can be delivered to all corners of the body efficiently. Reducing the thickness of blood may also decrease instances of dangerous clots forming and reduce the risk of stroke and heart attacks.
The same researchers, part-funded by the British Heart Foundation (BHF), also found nitrate can help the diseased heart to function more efficiently, help produce more of a compound that widens and opens blood vessels and help change bad white fat cells into good brown, fat-burning cells, which could combat obesity and reduce risk of type 2 diabetes.
In the first (1) study published this week in the Journal…

“Heart disease is the leading cause of death in the country,” said Fleming. “Learning what you can do to prevent heart disease is important and relevant for everybody.”

Increasing the amount of omega-3s in your diet, whether from fish or flax, will likely decrease your risk of getting heart disease, according to Penn State nutritionists.
A substantial amount of evidence exists supporting the heart-health benefits of eicosapentaenoic acid and docosahexaenoic acid (EPA and DHA), marine-derived omega-3 fatty acids. However, much less evidence exists to demonstrate the positive effects of alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid.
“The benefits reported for EPA and DHA are stronger because supplements of EPA and DHA were tested, and EPA and DHA was the only difference between the treatment and control groups,” said Jennifer Fleming, instructor and clinical research coordinator in nutritional sciences. “In contrast, in the ALA studies, there were diet differences beyond ALA between the treatment and control groups.”
EPA and DHA can be found in seafood and fish oil, and are often consumed in the form of dietary supplements…

“We estimate that individuals with significant plaque buildup in the arteries of the heart are much more likely to prevent a heart attack with aspirin use than to suffer a significant bleed” explains Miedema. “On the opposite end of the spectrum, if you don’t have any calcified plaque, our estimations indicate that use of aspirin would result in more harm than good, even if you have risk factors for heart disease such as high cholesterol or a family history of the disease.”

Cardiac Screening Test May Help Determine Who Should Take Aspirin to Prevent Heart Attack
A study involving the Minneapolis Heart Institute Foundation shows that a simple test to measure plaque in the arteries of the heart may help doctors better determine who will and will not benefit from use of aspirin therapy to prevent heart disease.
For over 30 years, aspirin has been known to prevent heart attacks and strokes, but who exactly should take a daily aspirin remains unclear. New research published today in Circulation: Cardiovascular Quality and Outcomes shows that your coronary artery calcium (CAC) score, a measurement of plaque in the arteries that feed the heart, may help determine whether or not you are a good candidate for aspirin.
“Many heart attacks and strokes occur in individuals who do not appear to be at high risk,” states lead author, Michael D Miedema, MD, MPH. “Individuals with known…

“Our research shows that the presence of obesity is enough to increase a person’s risk of future heart disease and that the disease may already be starting to form in their body. It’s important that these people learn this while they still have time to change their diet and exercise habits to prevent a future cardiovascular event.”

Research shows obese patients with no heart disease have greater risk of future disease.
Obese individuals who have no signs of cardiovascular disease show a much higher prevalence of early plaque buildup in the arteries compared to healthy normal weight individuals, according to a study published today in the Journal of the American College of Cardiology. The study challenges the idea of “healthy” obesity, and researchers recommend all obese individuals be counseled about their risks for cardiovascular disease and receive tips for achieving a healthy weight.
Obesity can often lead to cardiovascular disease through the development of dyslipidemia (abnormal amounts of fat or cholesterol in the blood), hyperglycemia (high blood sugar) and hypertension (high blood pressure)—all common conditions in obese individuals. But, the idea of “healthy” obese, individuals whose body weight puts them in the obese category but they show no signs of cardiovascular disease, is controversial.

“We undertook this study to understand the correlation between consuming a Mediterranean diet and specific health markers, including platelet levels and white blood cell counts, which can more specifically explain the diet’s benefits in reducing the long-term risk of cerebral and heart disease or other chronic conditions,” said lead study author Marialaura Bonaccio, PhD, of the Department of Epidemiology and Prevention at the IRCCS Istituto Neurologico Mediterraneo NEUROMED in Italy.

New research further illuminates the heart-healthy benefits of the Mediterranean diet, tying the eating plan to lower levels of platelets and white blood cells, two markers of inflammation. Inflammation has an association with greater risk of heart attack and stroke. Study results are published online today in Blood, the Journal of the American Society of Hematology (ASH).
The Mediterranean diet, characterized by generous servings of foods such as greens, whole grains, fish, and olive oil, has long been hailed as a heart-healthy eating plan. While the link between the diet and a reduction in inflammation has been established, the connection between the eating plan and levels of platelets and white blood cells, two specific inflammatory markers in the body, has remained unclear. Specifically, high platelet counts are associated with both vascular disease and non-vascular conditions such as cancer, and a high white blood cell count is a predictor of ischemic…

Eating whole grains is consistently associated with a reduced risk of chronic disease, including cardiovascular disease. Most of the benefits have been attributed to the relatively high fiber, vitamin, mineral and phytochemical content of whole grains. Notably, the soluble fiber beta-glucan found in oats has been recognized for its ability to lower both total and low-density lipoprotein cholesterol (LDL-C).

The soluble fiber in oats helps lower total and LDL cholesterol, but scientists now say that the cardiovascular health benefits of oats goes beyond fiber.
Eleven top scientists from around the globe presented the latest findings on the powerful compounds found in oats in a scientific session titled, Physicochemical Properties and Biological Functionality of Oats, at the 247th Annual Conference of the American Chemical Society in Dallas, TX. Scientists described research on the diverse health benefits of oats and emphasized the growing evidence that the type of phenolic compound avenanthramide (AVE) – found only in oats – may possess antioxidant, anti-inflammatory, anti-itch and anti-cancer properties. The culmination of the studies suggests that oat AVEs may play an important role in protecting the heart.
