Again there are echoes of our mantra, eat less; move move; live longer.
Adults in their early 60s, who spend less time sitting and more time engaged in light to vigorous physical activity, benefit with healthier levels of heart and vessel disease markers, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
The results from increased physical activity were found to be particularly good among women.
Physical inactivity is a well-known risk factor for cardiovascular disease and premature death from cardiovascular disease. Physical activity’s protective effect is likely due in part to its impact on biomarkers in the blood that help predict atherosclerosis risk.
“The 60 to 64 age range represents an important transition between work and retirement, when lifestyle behaviors tend to change,” said Ahmed Elhakeem, Ph.D., study author and senior research associate in epidemiology at Bristol Medical School, University of Bristol in the United Kingdom. “It may, therefore, be an opportunity to promote increased physical activity.
“In addition, cardiovascular disease risk is higher in older adults. It’s important to understand how activity might influence risk in this age group,” Elhakeem said. “We found it’s important to replace time spent sedentary with any intensity level of activity.” Continue reading
Eat less’ move more; live longer – and, we might add, the sooner the better, according to the latest information from the American Heart Associaton.
Being overweight may cause higher blood pressure and changes to the heart’s structure, even in young adults.
Even as a young adult, being overweight may cause higher blood pressure and thicken heart muscle, setting the stage for heart disease later in life, according to new research in the American Heart Association’s journal Circulation.
The study is the first to explore if higher body mass index (BMI) – a weight-for-height index – results in adverse effects on the cardiovascular system in young adults.
While observational studies can suggest associations between risk factors or lifestyle behaviors and heart disease, they cannot prove cause-and-effect. Here, investigators triangulated findings from three different types of genetic analysis to uncover evidence that BMI causes specific differences in cardiovascular measurements. Continue reading
For middle-aged men, eating higher amounts of protein was associated with a slightly elevated risk for heart failure than those who ate less protein, according to new research in Circulation: Heart Failure, an American Heart Association journal.
Despite the popularity of high protein diets, there is little research about how diets high in protein might impact men’s heart failure risk.
“As many people seem to take the health benefits of high-protein diets for granted, it is important to make clear the possible risks and benefits of these diets,” said Jyrki Virtanen, Ph.D., study author and an adjunct professor of nutritional epidemiology at the University of Eastern Finland in Kuopio. “Earlier studies had linked diets high in protein – especially from animal sources — with increased risks of Type 2 diabetes and even death.” Continue reading
I hope you enjoy fine tuning as much as I do. Yesterday, we learned about the value of activity coupled with exercise. Today, we look at the significance of how much we exercise.
Participating in exercise 4-5 days per week is necessary to keep your heart young, according to new research published in The Journal of Physiology. These findings could be an important step to develop exercise strategies to slow down such aging.
The optimal amount of exercise required to slow down aging of the heart and blood vessels has long been a matter of vigorous debate. As people age, arteries—which transport blood in and out of the heart—are prone to stiffening, which increases the risk of heart disease. Whilst any form of exercise reduces the overall risk of death from heart problems, this new research shows different sizes of arteries are affected differently by varying amounts of exercise. 2-3 days a week of 30 minutes exercise may be sufficient to minimize stiffening of middle sized arteries, while exercising 4-5 days a week is required to keep the larger central arteries youthful.
The authors performed a cross-sectional examination of 102 people over 60 years old, with a consistently logged lifelong exercise history. Detailed measures of arterial stiffness were collected from all participants, who were then categorized in one of four groups depending on their lifelong exercise history: Sedentary: less than 2 exercise sessions/week; Casual Exercisers: 2-3 exercise sessions per week; Committed Exercisers: 4-5 exercise sessions/week and Masters Athletes: 6-7 exercise sessions per week. (NB: an exercise session was at least 30 minutes). Continue reading
Eat less; move more; live longer. Simple acts with profound effects. And, according to the latest study, don’t wait till you are old to start.
Exercise can reverse damage to sedentary, aging hearts and help prevent risk of future heart failure – if it’s enough exercise, and if it’s begun in time, according to a new study by cardiologists at UT Southwestern and Texas Health Resources.

To reap the most benefit, the exercise regimen should begin by late middle age (before age 65), when the heart apparently retains some plasticity and ability to remodel itself, according to the findings by researchers at the Institute for Exercise and Environmental Medicine (IEEM), which is a collaboration between UT Southwestern Medical Center and Texas Health Presbyterian Hospital Dallas.
And the exercise needs to be performed four to five times a week. Two to three times a week was not enough, the researchers found in an earlier study. 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.

Regular readers know that I feel strongly that sleep is one of the cornerstones of good health. You can check out my Page – How important is a good night’s sleep? for more details.
According to the American Heart Association (AHA):
• Poor sleep – even if you don’t have sleep apnea – may be linked to higher risks of developing an irregular heartbeat.
• In addition, getting less rapid-eye movement (REM) sleep may also be linked to higher atrial fibrillation risks.
Disruptions in sleep may be raising your risks of an irregular heartbeat, known as atrial fibrillation (AF), according to preliminary research presented at the American Heart Association’s Scientific Sessions 2016. Continue reading
Regular readers know that I am a senior citizen who exercises daily and eats intelligent amounts and kinds of food to remain healthy. I take only a single drug for my prostate. Most of the seniors I know take a number of drugs, prescription and over the counter, to keep them going.
• For the first time, the American Heart Association has issued a statement cautioning that drugs used to treat a variety of conditions can cause or worsen heart failure.
• Patients should show each of their healthcare providers a complete list of their medications, including over-the-counter drugs and natural supplements.
• Patients with heart failure should consult with a health professional before starting or stopping any medication.
Commonly used medications and nutritional supplements may cause or worsen heart failure, according to the first scientific statement from the American Heart Association to provide guidance on avoiding drug-drug or drug-condition interactions for people with heart failure.
The statement provides comprehensive information about specific drugs and “natural” remedies that may have serious unintended consequences for heart failure patients.
Heart failure patients have, on average five or more separate medical conditions and take seven or more prescription medications daily, often prescribed by different healthcare providers.
“Since many of the drugs heart failure patients are taking are prescribed for conditions such as cancer, neurological conditions, or infections, it is crucial but difficult for healthcare providers to reconcile whether a medication is interacting with heart failure drugs or making heart failure worse,” said Robert L. Page II, Pharm.D., M.S.P.H., chair of the writing committee for the new scientific statement published in the American Heart Association journal Circulation. (my emphasis)
Cardiovascular disease is the leading global cause of death, accounting for 17.3 million deaths per year, a number that is expected to grow to more than 23.6 million by 2030, according to the American Heart Association and the American Stroke Association.

I must confess I was blown away by the information in this infographic from the American Heart Association.
The three parts are the whole story: What are my risks? What are the 7 Simple Keys to Prevention? Am I making progress or excuses? That says it all. Take your time on this, your heart health could depend on it.
When it comes to controlling our weight, a lot of people talk a good game, but the fact remains that 60 percent of us are overweight, 30 percent outright obese and adult onset diabetes is hitting our kids in their teens. So, we don’t do a very good job on controlling what we put into our systems. I thought this was a super infographic because it gets the reader to focus on what the impact of that slice of pizza is on his system.
As I wrote on my Page How to Lose Weight – and Keep it Off – everything you eat and drink becomes a part of you.
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.

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…

“You do not need to run a marathon to gain the benefits of physical activity — even quite low levels of activity can give you positive effects,” said Kasper Andersen, M.D., Ph.D., study co-author and researcher at the Uppsala University in Uppsala, Sweden. “Physical activity lowers many heart disease risk factors, which in turn lowers the risk of developing heart failure as well as other heart diseases.”

Exercising each day can help keep the doctor away.
In a new study reported in the American Heart Association journal Circulation: Heart Failure, researchers say more than an hour of moderate or half an hour of vigorous exercise per day may lower your risk of heart failure by 46 percent.
Heart failure is a common, disabling disease that accounts for about 2 percent of total healthcare costs in industrialized countries. Risk of death within five years of diagnosis is 30 percent to 50 percent, researchers said.
Swedish researchers studied 39,805 people 20-90 years old who didn’t have heart failure when the study began in 1997. Researchers assessed their total- and leisure time activity at the beginning of the study and followed them to see how this was related to their subsequent risk of developing heart failure. They found that the more active a person, the lower their risk for heart…

The quantity of almonds and muffins provided to each participant varied according to estimations to maintain his or her baseline weight. The muffins were formulated to provide the same number of calories and the same amount of saturated fat (SFA), polyunsaturated fat (PUFA), protein, and fiber as the almonds.

A study published in the British Journal of Nutrition shows that eating almonds daily may improve certain factors associated with heart disease risk.
The randomized, controlled clinical study, conducted by researchers at the University of Toronto, included 27 adult participants (mean age of 64 years) with elevated LDL cholesterol. Participants followed a diet low in saturated fat and cholesterol that also included each of three dietary interventions for four weeks each in a crossover design. Each day for four weeks, researchers gave one group 50–100 g (2–4 oz) of almonds. A control group received 100–200 g of muffins and a third group received 25–50 g (1–2 oz) of almonds plus 50–100 g of muffins. Each participant completed all three dietary treatments, so the total length of the study was 12 weeks.

The average American consumes 15 percent of his daily calorie allowance in added sugars. This amounts to 22 teaspoons a day, or 88 grams of sugar, according to Frank Hu, Professor of Nutrition and Epidemiology at the Harvard School of Public Health. That doesn’t include the naturally occurring sugars in fruits and whole foods.
The World Health Organization has recommended since 2002 that sugars should make up less than 10 percent of total energy intake per day. The new draft guideline also proposes that sugars should be less than 10 percent of total energy intake per day. It further suggests that a reduction to below 5 percent of total energy intake per day would have additional benefits. Five per cent of total energy intake is equivalent to around 25 grams (around 6 teaspoons) of sugar per day for an adult of normal Body Mass Index (BMI).
Much of the sugars consumed today are “hidden” in processed foods that are not usually seen as sweets. For example, 1 tablespoon of ketchup contains around 4 grams (around 1 teaspoon) of sugars. A single can of sugar-sweetened soda contains up to 40 grams (around 10 teaspoons) of sugar.
“The calories that added sugars contribute to your diet can pack on pounds without your even realizing it, leading to overweight and obesity, which are risk factors for type 2 diabetes. In addition, excess sugar consumption has links to high triglycerides, which can put you in danger of developing heart disease. Given these health implications, the American Heart Association (AHA) has issued guidelines for added sugar consumption. The association suggests that women get no more than 100 calories a day from added sugar, or about 6 teaspoons. For men, the association recommends limiting consumption to 150 calories daily, or 9 teaspoons”, according to Paula Martinac writing in SFGate.
On a daily calorie budget of 2000 calories, the AHA recommendation amounts to 7.5 percent. The U.S. Department of Agriculture offers no separate recommendation for sugar.
Professor Hu said that if you consume 10 percent of your calories in added sugar, you have a 40 percent increased chance of dying from heart disease. A person who consumes 25 percent of his calories in sugar has a 2.5 fold increased chance of dying from heart disease.
Here is a You Tube video of a sugar discussion moderated at Harvard.
