It’s official – spending time outside is good for you – Study

One of my favorite songs as a kid in the 1940’s was “Don’t fence me in.”
Here are some of the lyrics:
Oh, give me land, lots of land under starry skies above
Don’t fence me in
Let me ride through the wide open country that I love
Don’t fence me in

It appears I still feel that way, particularly when it comes to exercise. Working out in the health club really turns me off.

A new report reveals that exposure to green space reduces the risk of type II diabetes, cardiovascular disease, premature death, preterm birth, stress, and high blood pressure.

For my readers interested in bike riding …

I just ran across this infographic and thought it might be of interest to cyclists, but wait, maybe folks who don’t ride might enjoy it, too.

What do you think?

Exercise trumps genetics when it comes to heart disease

This is a case of the more the merrier as far as I am concerned. Eat less; move more; live longer is the mantra of this blog. And here, we have fresh research extolling the virtues of exercise in preventing heart disease.

Exercise, especially cardio fitness, could outweigh genetics when it comes to heart disease, according to new research.

runner-race-competition-female.jpg

The study, published in the journal Circulation, showed strength and cardiorespiratory fitness lowered the risk for heart disease across the board – whether people were categorized with low, intermediate or high genetic risk.

“Genes don’t have to determine destiny,” said Dr. Erik Ingelsson, lead study author and professor of medicine at Stanford University. “You can impact your risk by being more fit.”

I can’t say it enough times – take responsibility for your health. Don’t be blaming problems on your genes.

The study examined 482,702 people in England, Scotland and Wales who participated in the UK Biobank, an international research project that recruited participants between ages 40 and 69 years old from 2006 to 2010. Researchers followed those who didn’t have any signs of heart disease for about a decade. They tracked activity and exercise through questionnaires, grip strength measurements and other tests.

“It’s was a very consistent pattern for all of these different measures,” according to Ingelsson, who said he believes it is the largest such study. “All were associated with lower risk of disease in the future.”

Researchers specifically investigated the genetic profiles for those at highest risk for coronary heart disease and a heart rhythm disorder called atrial fibrillation, or AFib. Those at the highest risk who also had the highest levels of cardiorespiratory fitness – conducted through oxygen and effort measurements on a stationary bicycle – cut their coronary heart disease risk by 49 percent and their AFib risk by 60 percent.

The research is important – and timely, said Dr. Russell Pate, a professor in the University of South Carolina’s Department of Exercise Science in the Arnold School of Public Health.

“They’ve demonstrated that physical activity and fitness were associated with a reduced risk of cardiovascular disease outcomes across a continuum of persons,” Pate said. “For the public, that’s an important message. You can’t eliminate genetic risk, but you can absolutely attenuate the effects.”

Pate just finished a term on a committee that writes the federal Physical Activity Guidelines. The group’s advisory report was released last month and will be the foundation for the U.S. Department of Health and Human Services’ policy recommendations on how physical activity can promote health and reduce the risk of disease. The advisory group’s recommendations have a chapter emphasizing the importance of exercise with people who have chronic conditions.

The latest research is “added ammunition in making the case that promotion of physical activity deserves a prominent place in public health,” Pate said.

Heart disease is the leading cause of death in the world, though there are proven ways to lower risk. People often hear about risk factors such as smoking, high cholesterol, high blood pressure and excess weight. Now, the expanding field of genetics can provide more information, Pate said.

“We’re in a new era in terms of people being able to know their risk status,” he said. “We can now provide information at a new and higher level.”

Ingelsson and the study authors suggested it could lead to individualized strength-training and aerobic programs to help people counteract their genetic risk for heart disease.

But one important question to answer, and a potential future area of study, Ingelsson said, is whether that knowledge truly is power. If we know that lifestyle choices like exercise could offset our genetic risk for disease, how likely are we to start that healthier lifestyle?

Does walking satisfy cardiovascular exercise needs?

Regular readers know that I am a big fan of the simple exercise of walking. I have called it the Cinderella of the exercise world because it is so unappreciated. Check out my Page – Why you should walk more for further details on this superb form of movement.

No comes Megan Teychenne and Clint Miller writing in The Conversation about the nature and value of walking.

“Walking leads to a remarkable reduction in the risk of heart disease, type 2 diabetes, some cancers, arthritis, depression, anxiety and insomnia, and premature death from all causes.

Stanford professor Michel Serres hikes the Dish on a regular basis.

“The health benefits of walking stem from the changes that occur in our body systems as a result of exercising. For some of these health conditions, fitness has been shown to be a particularly important factor for prevention.

“The term fitness is quite often used to describe , but having a high level of fitness actually refers to all components of health-related physical fitness which includes muscular strength and endurance, flexibility, body composition, and of course aerobic (or heart) fitness. So is walking enough in terms of the we need?

Happy Easter Wishes – Try Biking – Infographics

Easter comes at a time when the weather is mellowing and more folks think about getting outside and enjoying the air. Maybe slimming down. The whole idea of Easter is rejuvenation, right? Spring; new life. Well, biking is the coolest way I know to get outside and feel reborn.

I hope you will enjoy these images and ideas as much as I do.

Recreational, commuter biking lower cardiovascular disease risk – AHA

As an enthusiastic bicycle rider and supporter of the exercise, I was really pleased to see the results of the American Heart Association studies. Here is a summary:

    •    People who bike regularly, either recreationally or as a way to commute, appear to have a lower risk of cardiovascular illness, according to studies conducted in Denmark and Sweden.
    •    Middle-aged and older Danes who took up biking and stuck with it had a 26 percent lower risk of developing coronary artery disease, compared with non-bikers.
    •    In Sweden, those who regularly biked to work were less likely to develop high blood pressure, high cholesterol, pre-diabetes and obesity — key risk factors for cardiovascular illness.

Vitamin B-12

B12_sourcesAs essential as B-12 is, it can be tricky to get enough in your diet. Foods that contain B-12 include red meat, organ meats like kidneys and liver, eggs, yogurt, and cheese, and seafood — definitely a problem for vegans or vegetarians. Additionally, many people, especially adults over 50, have trouble absorbing B-12. Commonly prescribed drugs can also cause nutritionally deficiencies, including Vitamin B-12, which have been linked to many health conditions.

Our Better Health

17th November 2014      By Dr. Edward F. Group     Contributing Writer for Wake Up World

Vitamin B-12 is one of the more discussed vitamins and for good reason. It is important for your health overall as it helps several organs and systems in your body function properly, including the brain, the nervous and skeletal systems, DNA replication and energy creation processes.

Let’s take a look at a few reasons why it’s important to make sure you’re getting enough Vitamin B-12.

1. Supports Cardiovascular Health

You’ve probably heard that B-12 is good for cardiovascular health. The way that works is this…

Homocysteine is a protein that naturally forms as a byproduct of your body’s processes. When it builds up, it can corrode and inflame arteries and blood vessels, placing strain on the heart and cardiovascular system. Vitamin B-12 helps converts homocysteine to methionine, a protein the body uses…

How About Sardines and Crackers from Costco?

I average going to Costco about once every seven to 10 days. For that reason when I saw sardines for sale there, I naturally took them as a new product. Now, I may have missed them previously, or the store may have moved them to a new position in the warehouse that became more obvious to me, but I don’t remember ever seeing them before. I like sardines and have been eating the Chicken of the Sea Brisling ones I got from a local supermarket. Naturally, I had to try the Costco ones.

sardines-vs-anchovies-1314903jpg-e6baaaadd71adeea

First of all, why eat sardines? The World’s Healthiest Foods site says, “Sardines are named after Sardinia, the Italian island where large schools of these fish were once found. While sardines are delightful enjoyed fresh, they are most commonly found canned, since they are so perishable. With growing concern over the health of the seas, people are turning to sardines since they are at the bottom of the aquatic food chain, feeding solely on plankton, and therefore do not concentrate heavy metals, such as mercury, and contaminants as do some other fish.

“While there are six different types of species of sardines belong to the Clupeidae family, more than 20 varieties of fish are sold as sardines throughout the world. What these fish share in common is that they are small, saltwater, oily-rich, silvery fish that are soft-boned. In the United States, sardines actually refers to a small herring, and adult sardines are known as pilchards, a name that is commonly used in other parts of the world.

170654b“Sardines are rich in numerous nutrients that have been found to support cardiovascular health. They are one of the most concentrated sources of the omega-3 fatty acids EPA and DHA, which have been found to lower triglycerides and cholesterol levels; one serving (3.25 ounce can) of sardines actually contains over 50% of the daily value for these important nutrients. Sardines are an excellent source of vitamin B12, ranking as one of the World’s Healthiest Food most concentrated in this nutrient. Vitamin B12 promotes cardiovascular well-being since it is intricately tied to keeping levels of homocysteine in balance; homocysteine can damage artery walls, with elevated levels being a risk factor for atherosclerosis.” Continue reading

Researchers Pinpoint Upper Safe Limit of Vitamin D Blood Levels

Good info on the rockstar of vitamins …

Cooking with Kathy Man

Researchers claim to have calculated for the first time, the upper safe limit of vitamin D levels, above which the associated risk for cardiovascular events or death raises significantly, according to a recent study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).

There is increasing evidence that vitamin D plays a pivotal role in human physiology. Vitamin D deficiency has been linked to cardiovascular events and mortality, but previous studies have found supplementation fails to decrease mortality or cardiovascular events, while other studies found only minor positive effects.

“The unpredictable results from previous studies may be due to the misconception that ‘the higher the better,’” said Yosef Dror, PhD, of Hebrew University in Rehovot, Israel, and lead author of the study. “Although our study did not directly test the impact of vitamin D supplementation, we believe our results suggest it may be possible that…

New Understanding of Cardiovascular Health Benefits of Vegan, Vegetarian Diets

While carnitine is naturally occurring in red meats, including beef, venison, lamb, mutton, duck, and pork, it’s also a dietary supplement available in pill form and a common ingredient in energy drinks. With this new research in mind, Hazen cautions that more research needs to be done to examine the safety of chronic carnitine supplementation.

Cooking with Kathy Man

A compound abundant in red meat and added as a supplement to popular energy drinks has been found to promote atherosclerosis – or the hardening or clogging of the arteries – according to Cleveland Clinic research published online this week in the journal Nature Medicine.

The study shows that bacteria living in the human digestive tract metabolize the compound carnitine, turning it into trimethylamine-N-oxide (TMAO), a metabolite the researchers previously linked in a 2011 study to the promotion of atherosclerosis in humans. Further, the research finds that a diet high in carnitine promotes the growth of the bacteria that metabolize carnitine, compounding the problem by producing even more of the artery-clogging TMAO.

The research team was led by Stanley Hazen, MD, Ph D, Vice Chair of Translational Research for the Lerner Research Institute and section head of Preventive Cardiology & Rehabilitation in the Miller Family Heart and Vascular Institute…
