Published on Leave a comment on Try Exercise First For Erectile Dysfunction

Erectile dysfunction is a serious problem for many men, especially as they get older. A review and analysis of 11 well-done studies  looking at whether exercise helps with erectile dysfunction found that YES, it does.

They found that exercising for at least 30 minutes three times a week can be just as effective as Viagra and Cialis at improving erectile dysfunction (ED). Also, the worse the ED at the start of a study, the more exercise helped.

What were the exercises? Any aerobic activities that got the heart pumping, such as cycling, tennis, or brisk walking. In the studies looked at, the exercise sessions were typically 30 to 60 minutes, and occurred 3 to 5 times a week. Some studies had the men exercise on their own, while other studies had the men attend supervised exercise sessions.

Bottom line: Exercise improved ED in all men! It didn't matter what the men weighed, their medication use - it helped them all. (Examples of earlier studies looking at exercise and physical activity helping improve ED.)

This could be because ED is considered a measure of a man's overall heart health. When there is heart disease, inflammation, and narrowing or hardening of the arteries - then ED increases. Physical activity, on the other hand, improves health, including heart disease.

We've known for a while that exercise and physical activity lower the risk of developing heart disease. It turns out that a good exercise that many of us do in the course of ordinary life is walking up and down stairs. Yes, that counts!

A large study (458,860 adults) used data from the UK (Biobank). They found that walking up 5 flights of stairs (about 50 steps) daily was associated with a 20% lower risk of developing heart disease (including ischemic strokes) after 5 years.

Interestingly, persons who were stair climbers at the beginning of the study, but then stopped at some point during the 5 year length of the study had a higher risk of heart disease than those who never climbed stairs.

Bottom line: Walk up stairs whenever you can. It's good for your heart!

From Science Daily: Walking more than five flights of stairs a day can cut risk of heart disease by 20 percent, study says

Forget walking 10,000 steps a day. Taking at least 50 steps climbing stairs each day could significantly slash your risk of heart disease, according to a new study from Tulane University. ...continue reading "Daily Walking Up Stairs Lowers the Risk of Heart Disease"

Published on Leave a comment on Being Physical Fit Is Linked To A Lower Risk of Atrial Fibrillation and Stroke

A recent large study found another great reason for being physically active. The researchers found that physical fitness is linked to  atrial fibrillation (AFib) and stroke.

Atrial fibrillation is a heart rhythm disorder, and having it is linked to a much higher risk of having a stroke. The researchers found that being physically fit (exercise! physical activity!) is linked to lower rates of atrial fibrillation, stroke, and MACE (major adverse cardiovascular events, such as stroke or heart attack leading to death).

There was an eleven year follow up of the approximately 15,450 participants, all of whom did not have atrial fibrillation at the start of the study. The study tested the  physical fitness of the participants (average age 55 years) on an exercise treadmill.

Bottom line: Physical activity and physical fitness are important for reducing the risk of developing heart problems, including atrial fibrillation. Yes, even taking walks (brisk is best) will improve physical fitness.

From Science Daily: Keep fit to avoid heart rhythm disorder and stroke

A study in more than 15,000 people has found that physical fitness is linked with a lower likelihood of developing atrial fibrillation and stroke. The research is presented at ESC Congress 2023.

It turns out that a body part considered unimportant, and that frequently gets removed during operations - is actually important for adult health. This body part is the thymus. The thymus is frequently (routinely) removed during heart surgery for easier access to the heart and major blood vessels.

The thymus is an organ of the immune system within which T cells mature. For years the medical community regarded the thymus as only important before birth and during childhood, but "nonfunctional" in adults. A recent large study found that this view is wrong - that even in adults the thymus is important for immune and overall health.

Massachusetts General Hospital researchers found that after 5 years a higher risk of death from any cause (all cause mortality), cancer, and even autoimmune diseases among those who had thymus removal (thymectomy) versus those who had similar heart (cardiothoracic) surgery without thymus removal.

In other words, we need all our body parts! Even if the medical community doesn't quite understand (at this time) why we have them.

Excerpts from Medical Xpress: Study reveals unexpected importance of the thymus in adults

Published on Leave a comment on Study Finds Mediterranean Diet Lowers the Risk of Developing Heart Disease In Women

A recent study was good news for those wishing to lower their chances of developing heart disease (cardiovascular disease) without the use of medications. Instead, focus on the foods you eat, specifically those in a Mediterranean-style diet.

The Univ. of Sydney researchers did an analysis of 16 existing studies (with 722,495 women) and found that women following a Mediterranean diet lowered their odds of developing heart disease by 24% and lowered their risk of early death by 23%.

In this study, a Mediterranean diet meant eating a diet rich in fruits, vegetables, whole grains, legumes, nuts, seeds, extra virgin olive oil. Moderate amounts of seafood, low to moderate in wine consumption, and low in red/processed meats, dairy products, animal fat, and processed foods.

Why is the Mediterranean diet beneficial? The diet focuses on whole foods that are also rich in fiber, antioxidants, has an increased intake of all sorts of nutrients (vitamins, minerals, flavanols, etc.), less oxidative stress, it's anti-inflammatory, reduced glycemic load, boosts the immune system, and feeds the beneficial microbes in our gut microbiome.

Interestingly, studies find that frequent consumption of extra virgin olive oil (EVOO) lowers the risk of death from several diseases (heart disease, cancer, neurogenerative disease, and respiratory disease), lowers the incidence of breast cancer, and promotes healthier brain aging. A Mediterranean diet is associated with numerous health benefits (e.g., lower dementia risk) besides a lower heart disease risk.

These findings are important because heart disease is the leading cause of death globally, according to the World Health Organization. According to the CDC, it is the number 1 killer of women in the United States.

Say it over and over to yourself: Don't eat highly processed foods, don't eat foods with additives (e.g., emulsifiers, colors), don't eat foods/beverages with high fructose corn syrup, don't eat lots of pre-packaged foods or fast foods.

Why? This kind of high fat, low-fiber Western diet (which most of us eat), is linked to lots of health problems  and also an unhealthy gut microbiome. Cancer, diabetes, heart disease!

Instead, eat a Mediterranean style diet - a diet rich in fruits and vegetables, whole grains, seeds, nuts, whole grains, legumes. Also, lots of olive oil. This is a high fiber diet linked to good health and a healthy gut microbiome.

Research finds harms (e.g., harmful alterations of the gut microbiome or intestinal lining, cancer) from ingredients added to highly processed foods, such as emulsifiers, carrageenan, artificial sweeteners, maltodextrin, carboxymethyl cellulose, polysorbate-80, artificial colors and flavors, high fructose corn syrup, etc. Bottom line: Try to avoid any ingredient that's not normally in your kitchen! Read ingredient lists on labels.

Published on Leave a comment on Exercise Snacks Can Be An Easy Way To Improve Fitness

Some good news for those finding it hard to find time or motivation for lengthy exercise sessions. It turns out that frequent little bursts of exercise about 1 to 2 minutes long also have tremendous health benefits, even if you spend most of the day sitting. Think of them as "exercise snacks".

An exercise or activity snack is a "brief snippet of exercise, usually lasting a minute or two, and done frequently during the day". There are studies (exercise snacking research!) finding it a good way to improve fitness, especially cardiorespiratory fitness and cardiometabolic health. The benefits of exercise snacking can be comparable to lengthier traditional workouts.

Some examples of exercise or activity snacks: walking quickly up and down a staircase, walking quickly around a room, rising and lowering 15 times from a chair, and jumping up and down. Ideally anything that'll raise your heart rate and breathing briefly. Sounds easier than going to a gym, doesn't it?

The Washington Post has a nice article about exercise snacking. Below that is an example of recent exercise snack research.

Here’s an easy and effective way to add physical activity to your daily routine during the new year: turn your exercise into a snack.

New research shows exercise “snacks,” which consist of brief spurts of exertion spread throughout the day, can improve metabolic health, raise endurance and stave off some of the undesirable changes in our muscles that otherwise occur when we sit too long.

Published on Leave a comment on Drinking Tea Every Day Has Health Benefits

Some good news. A study found that frequent consumption of foods and beverages containing flavonoids by elderly women had health benefits. Flavonoids are compounds found naturally in plants, and that have health-promoting effects.

The 881 women (aged 78 to 82 years) in the Australian study were less likely to have abdominal aortic calcification (AAC) if they ingested high levels of flavonoids in their diet. This is significant because AAC is a major predictor of cardiovascular disease events, such as heart attacks, strokes, and death.

Drinking black tea daily was their major source of flavonoids. Drinking 2 to 6 cups a day lowered the risk of having extensive AAC.

Good flavonoid sources are: black tea, green tea, wine, apples, nuts, citrus fruits, berries, grapes, onions, broccoli, kale, parsley, and dark chocolate. There are different types of flavonoids, each with different health-promoting effects. This is why it's good to eat a variety of fruits and vegetables.

Great news for those who like honey! Even though honey is really sweet (lots of sugars!), eating it actually helps your health. Univ. of Toronto researchers analyzed 18 well done studies and found that honey improved key measures of cardiometabolic health, including blood sugar and cholesterol levels.

These results are interesting because they contrast with other research finding a high intake of sugars (e.g., sugar, high fructose corn syrup, soda) contributing to obesity, type 2 diabetes, and cardiovascular disease. Unfortunately, most regulatory agencies, including the World Health Organization, the Heart and Stroke Foundation, and the FDA (US Food and Drug Administration), include honey within their definition of free or added sugars. And advise limiting intake.

However, honey is not like other sugars. Honey has a complex composition of organic acids, minerals, vitamins, enzymes, proteins, amino acids, and bioactive substances. Rare sugars constitute around 14% of the sugar content of honey. Raw honey also contains probiotic bacteria.

All sorts of studies (in vitro, animal, clinical) have shown that honey has health benefits for cardiometabolic health. Among these benefits are improvements in body weight, inflammation, lipid profile, and glycemic control.

What kind is best? The Univ. of Toronto researchers found that the best health results are found with consumption of raw honey, clover honey, and robinia honey. In other words, honey that is not processed (raw honey) or from only 1 floral source (e.g., clover, acacia/robinia).

How much is best? The median dose consumed was 40 g or about 2 tablespoons daily, usually added to foods or beverages as a sweetener (e.g., in tea, mixed with yogurt, spread on bread) . Enjoy!

Published on Leave a comment on Coffee Drinking Linked to Longer Life and Lower Risk of Heart Disease

It seems that every so often another study finds that daily coffee consumption is healthy for a person. A recent large study found that daily drinking of 2 to 3 cups coffee is associated with a lower risk of early death (from any cause) and lower risk of cardiovascular  disease, when compared to non-coffee drinkers.

The University of Melbourne researchers also found that drinking ground and instant coffee, but not decaffeinated coffee, was associated with a reduction in arrhythmias including atrial fibrillation. In this study cardiovascular disease included heart disease, congestive heart failure, and ischemic stroke.

More good news - it applied to all types of coffee (ground, decaffeinated, and instant). However, when looking at the study results, ground coffee appears to be more beneficial than decaf or instant coffee. Two to three cups of coffee per day appeared to be the most beneficial.

The researchers point out that coffee contains more than 100 biologically active components, which are contributing to its health effects.[Other coffee studies] They also said that mild to moderate coffee consumption should be considered part of a heart healthy lifestyle. Great news!

From Science Daily: Coffee drinking is associated with increased longevity

Drinking two to three cups of coffee a day is linked with a longer lifespan and lower risk of cardiovascular disease compared with avoiding coffee, according to research published today in the European Journal of Preventive Cardiology, a journal of the ESC.1 The findings applied to ground, instant and decaffeinated varieties. ...continue reading "Coffee Drinking Linked to Longer Life and Lower Risk of Heart Disease"
