Not exercising can harm you more than smoking, drinking: Study

Exercise helps you live longer – this is something everybody knows. But a new study published recently in the journal JAMA Network Open goes a step further, stating that a sedentary lifestyle is worse for your health than smoking, drinking, and even suffering from a heart disease. Dr Wael Jaber, a cardiologist at the Cleveland Clinic and senior author of the study, called the results “extremely surprising.”

“Being unfit on a treadmill or in an exercise stress test has a worse prognosis, as far as death, than being hypertensive, being diabetic or being a current smoker,” Jaber told CNN.

Stating that being unfit should be treated almost like a disease that should come with a prescription which should be exercise, Jaber said, “We’ve never seen something as pronounced as this and as objective as this”.

 

With a sample size of 122,007 people, researchers involved with the study studied these patients who underwent exercise treadmill testing at Cleveland Clinic between January 1, 1991 and December 31, 2014 to measure all-cause mortality relating to the benefits of exercise and fitness. Those with the lowest exercise rate accounted for 12 per cent of the participants.

Researchers found that there is an established link between a longer, healthier life and high levels of exercise. Jaber said the other big takeaway from the research can be that fitness leads to a longer life, with no limit to the benefit of aerobic exercise.

While, for a long time, some researchers have always been concerned that “ultra” exercisers might be at a higher risk of death, the study put that worry to rest and stated that was not the case. “There is no level of exercise or fitness that exposes you to risk,” Jaber said. “We can see from the study that the ultra-fit still have lower mortality.”

It was also seen in the findings of the study that women reaped more benefits of exercise than their male counterparts. The benefits of exercise were seen across all ages and in both men and women, “probably a little more pronounced in females,” Jaber said. “Whether you’re in your 40s or your 80s, you will benefit in the same way.”

“People who do not perform very well on a treadmill test have almost double the risk of people with kidney failure on dialysis.” Continued Jaber, “If you compare the risk of sitting versus the highest performing on the exercise test, the risk is about three times higher than smoking.”

Comparing people who lead a sedentary lifestyle to the top exercise performers, the researchers involved in the study found that the risk associated with death is 500 per cent higher in the case of people in the former category.

Fruit and Vegetable Juices That Enhance the Immune System

The Kashmir Monitor

Published

on

Everyone knows that fresh fruits and vegetables are loaded with nutrients that offer a wide range of benefits for the mind and body. Certain fresh produce help enhance your immune system, making it possible for you to easily avoid various infections and diseases. Juicing the following allows you to boost your immunity in a truly refreshing and delectable way:

Carrots

The sweetness of carrot juice makes it loved by kids and adults alike. Carrots get their characteristic bright orange color from its rich supply of beta carotene, a nutrient converted into vitamin A for sharper vision and better eye health. More importantly, vitamin A is an essential nutrient for a stronger immunity.

 

Lemon

Vitamin C in lemons makes these citrus fruits excellent boosters of your immune system. Vitamin C is a well-known powerful antioxidant that protects the body from colds, cough, flu and others. Lemon juice may be acidic, but it has an alkalizing property once ingested, helping to restore optimal pH balance in the body.

Apples

Other than vitamins and minerals, apples also contain plenty of insoluble fiber. This type of carbohydrates that cannot be digested by the body works as a broom that sweeps out toxins along the intestinal tract. With all of those accumulated poisonous substances out of your body, your immunity is in top-form.

Kiwi

When it comes to fruits, some of the best sources of vitamin C are kiwis. Other than this super antioxidant, kiwis also contain vitamins A and E, both of which are necessary for a stronger immune system. Insoluble fiber and potassium in these fruits are also highly favorable for your cardiovascular system.

Cranberries

Cranberry juice is admired for its ability to bolster the urinary tract system. However, it also contains plenty of vitamin C that helps safeguard you from illnesses brought about by invading microorganisms such as bacteria and viruses.

Broccoli

A vegetable that makes for an excellent immune-boosting juice is broccoli, thanks to its rich supply of beta carotene and vitamin C. Every glass of broccoli juice also provides your body with sulphur, a mineral with powerful antimicrobial properties. Sulphur promotes healing as well because it detoxifies the body at a cellular level.

Beets

What makes beet juice capable of supporting the immune system is its long list of vitamins and minerals. Some of them include vitamins A and C, iron, calcium, potassium and manganese. When juicing, it’s a good idea to mix beets with other fruits and vegetables of your choice due to its strong, earthy flavor.

Reduce asthma symptoms with Omega-3

A new study has found that consuming a diet rich in omega-3 fatty acids is linked to fewer childhood asthma symptoms which are triggered by indoor air pollution.

The study published in ‘American Journal of Respiratory and Critical Care Medicine’, lays out that families and health care providers may be able to protect children from harmful effects of indoor air pollution by serving a diet rich in omega-3 fatty acids while reducing foods rich in omega-6 fatty acids such as soyabean oil and corn oil.

“Our group is working on ways to reduce the levels of indoor air pollution in Baltimore City homes,” said lead author of the study, Emily Brigham. “Results are promising, but we don’t want to stop there,” Brigham added.
The study found that for each additional gram of omega-6 intake, children had 29 per cent higher odds of being in a more severe asthma category.

 

Conversely, with each 0.1-gram increase in levels of omega-3 fatty acids in the diet, researchers saw 3 to 4 per cent lower odds of daytime asthma symptoms.

Indoor air pollution, from sources including cooking, cleaning activities and cigarette smoke, is a known trigger for asthma symptoms.

Omega-3 fatty acids, which are found abundantly in fish and certain nuts and seeds, are considered healthy as they are known to reduce inflammation.

Omega-6 fatty acids, primarily found in vegetable oils (including corn, soybean, safflower, and sunflower), as came out in other studies, have mixed effects on health, but have the potential to promote inflammation.

The researchers, however, noted that it doesn’t prove the relationship between fatty acids and asthma severity.

“Among populations known to be disproportionately affected by asthma, we may find that improving diet and air pollution together has the greatest impact on health,” said Brigham.

New cell that can heal hearts discovered

The Kashmir Monitor

Published

on

Researchers have discovered a previously unidentified cell population which could lead to new treatments for patients with injured hearts.

The cell, described in the journal Immunity, was discovered in the pericardial fluid found in the sac around the heart of a mouse with heart injury. The researchers from the University of Calgary in Canada found that a specific cell, a Gata6+ pericardial cavity macrophage, helps heal an injured heart in mice.

The same cells were also found within the human pericardium of people with injured hearts, confirming that the repair cells offer the promise of a new therapy for patients with heart disease. “Our discovery of a new cell that can help heal injured heart muscle will open the door to new therapies and hope for the millions of people who suffer from heart disease,” said Paul Fedak, a professor at the University of Calgary.

 

“The possibilities for further discovery and innovative new therapies are exciting and important,” said Fedak. Heart doctors had never before explored the possibility that cells just outside the heart could participate in healing and repair of hearts after injury, researchers said.

Unlike other organs, the heart has a very limited capacity to repair itself which is why heart disease is the number one cause of death in North America, they said. “We always knew that the heart sits inside a sac filled with a strange fluid,” said Fedak. “Now we know that this pericardial fluid is rich with healing cells. These cells may hold the secret to repair and regeneration of new heart muscle,” he said.
