As you can see, majority of the risk factors that can hurt your heart health can be prevented – the answer lies in your hands.
These are risk factors along with the preventive options:
High blood cholesterol – Eat right by having a balanced and healthy diet. Your fasting blood glucose should preferably be less than 100 mg/dL.
High blood pressure – Manage blood pressure through exercise and medications. Keep the numbers below 120/80 mm Hg.
Physical inactivity – Get moving and stand more. Spend 150 minutes of moderate intensive activity per week, like brisk walking. And opt for 75 minutes of vigorous-intensity activity. Eat less; move more; live longer. A sedentary lifestyle is a killer. Check out my Page – Do you know the dangers of too much sitting?
Obesity and overweight – Lose weight to find your healthy weight. Target a Body Mass Index (BMI) of less than 25. Check out my Page – How dangerous is a big belly?
I stumbled across this and thought it might interest you. As regular readers know I am a 78-year-old guy who lives in Chicago and rides his bike daily. I am most grateful for the ability to do just that. There are many seniors, perhaps someone in your family, who have lost some mobility. In the course of writing this blog I have become aware of just how damaging a sedentary lifestyle can be. I thought there were some interesting ideas expressed in the video (less than 3 minutes) which was produced by the BBC in Britain.

The investigators found that when they temporarily decreased activity in the dorsolateral prefrontal cortex – the brain network responsible for self-control – participants evaluated high-calorie snacks more positively, paid more attention to appealing images of such foods, and reported stronger urges to eat them than usual.
“We used a technique called transcranial magnetic stimulation to temporarily suppress the operation of a part of the brain that is involved in inhibition, known as the dorsolateral prefrontal cortex,” said Peter Hall, professor of Public Health and Health Systems and co-author of the study. “This resulted in increased attention to high-calorie food images, as well as stronger cravings for and more consumption of such foods when given an opportunity to sample them.”
The study involved 28 young adult females who reported frequent cravings for high-calorie foods but were otherwise healthy. Eighty-nine percent of the participants consumed more food after real suppressive stimulation than after a placebo stimulation.
“Several lifestyle factors affect the function of the dorsolateral prefrontal cortex,” said Cassandra Lowe, lead author of the study and a PhD graduate from Waterloo’s School of Public Health. “For example, aerobic exercise has been shown to enhance it, while lack of sleep and stress can impair it – so there may be a link between these lifestyle factors and overeating via their impacts on the brain.”
I confess, I love it when new discoveries meet my bias. I created the Page – Do you know the dangers of too much sitting? nine months ago. What follows is the latest information on prolonged sitting from the American Cancer Society (ACS).
A new ACS study links prolonged sitting time with a higher risk of death from all causes, including 14 of 22 measured causes of death and 8 of the 10 most common causes of death. The link existed even after adjusting for levels of moderate-vigorous intensity physical activity. The study appears early online in the American Journal of Epidemiology.
Advancements in technology have led to a significant increase in the amount of time spent sitting. In addition, sedentary time increases with aging, a time when the risk of chronic disease also increases. In the United States, most leisure time is spent in sedentary behaviors such as television viewing. In one Australian study, it was estimated that 90% of total non-occupational time was spent sedentary, and that 53% of sedentary time was spent on screen time (computer or television).Continue reading →
Eat less; move more; live longer remains the mantra of this blog. On the positive side, we need to use these organic machines that we live in – our bodies. On the negative side, we need to fight the temptation to slip into a sedentary lifestyle.
Herewith a blog post from Matthew Sloan, Executive Editor, Harvard Men’s Health Watch.
When I was in high school, I mowed my grandmother’s lawn once a week. Yet every time I arrived, she would have already mowed a small part of the back yard. I always told her she didn’t need to do that, but she insisted. At the time I didn’t understand why she felt compelled to do this every week, but now that I’m inching closer and closer to her age then, I get it: it was something she could do to stay active. She knew that to stave off the effects of a sedentary lifestyle, it is important to move more every day.
The older we get, the more likely we are to lapse into a sedentary lifestyle. In fact, an estimated 67% of older adults report sitting for more than eight hours per day, and only 28% to 34% of adults ages 65 to 74 are physically active, according to the Department of Health and Human Services.Continue reading →
It’s been a couple of years now since I first learned the dangers of prolonged sitting. Someone even called ‘sitting the new smoking.‘ I thought that might have been excessive – might have been. However, this new information from UCLA researchers certainly adds resonance to the problem for seniors.
Sitting too much is linked to changes in a section of the brain that is critical for memory, according to a preliminary study by UCLA researchers of middle-aged and older adults.
Studies show that too much sitting, like smoking, increases the risk of heart disease, diabetes and premature death. Researchers at UCLA wanted to see how sedentary behavior influences brain health, especially regions of the brain that are critical to memory formation.
UCLA researchers recruited 35 people ages 45 to 75 and asked about their physical activity levels and the average number of hours per day they spent sitting over the previous week. Each person had a high-resolution MRI scan, which provides a detailed look at the medial temporal lobe, or MTL, a brain region involved in the formation of new memories.
The researchers found that sedentary behavior is a significant predictor of thinning of the MTL and that physical activity, even at high levels, is insufficient to offset the harmful effects of sitting for extended periods.
This study does not prove that too much sitting causes thinner brain structures, but instead that more hours spent sitting are associated with thinner regions, researchers said. In addition, the researchers focused on the hours spent sitting, but did not ask participants if they took breaks during this time.
The researchers next hope to follow a group of people for a longer duration to determine if sitting causes the thinning and what role gender, race, and weight might play in brain health related to sitting.
MTL thinning can be a precursor to cognitive decline and dementia in middle-aged and older adults. Reducing sedentary behavior may be a possible target for interventions designed to improve brain health in people at risk for Alzheimer’s disease, researchers said.
The concept that being inactive and heart disease are related is a pretty well-accepted idea in our society today. There are many explanations for why this occurs and they all mainly have to do with metabolism, food intake, and energy expenditure. (This is why you’re supposed to run 10 miles if you eat a strip of bacon, right?)
While these ideas are certainly not wrong, I think there’s an important concept that many of us are missing when we try to lower our heart and vessel disease risk.
What I’m talking about here is the concept of a rising “vascular age” due to inactivity and stiffness of our bodies.
But first, let’s talk about blood flow in the body.
How Blood Normally Flows In The Body
For the sake of discussion, let’s start thinking about blood flow at the level of the heart. The heart is a…
