American Heart Association says combo of overweight, high sodium intake speeds cell aging in teens

 

American Heart AssociationSan Francisco, CA – Overweight or obese teenagers who eat lots of salty foods may show signs of faster cell aging, according to research presented at the American Heart Association’s Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014.

“Lowering sodium intake, especially if you are overweight or obese, may slow down the cellular aging process that plays an important role in the development of heart disease,” said Haidong Zhu, M.D., Ph.D., lead author of the study and assistant professor of pediatrics at Medical College of Georgia, Georgia Regents University in Augusta, GA.

American Heart Association reports spices and herbs intervention helps adults reduce salt intake

 

American Heart AssociationSan Francisco, CA – Teaching people how to flavor food with spices and herbs is considerably more effective at lowering salt intake than having them do it on their own, according to research presented at the American Heart Association’s Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014.

NASA to launch Lunar Atmosphere and Dust Environment Explorer (LADEE) to study Twilight Rays on the Moon

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Back in the 60s and 70s, Apollo astronauts circling the Moon saw something that still puzzles researchers today. About 10 seconds before lunar sunrise or lunar sunset, pale luminous streamers would pop up over the gray horizon. These “twilight rays” were witnessed by crew members of Apollo 8, 10, 15 and 17.

Back on Earth, we see twilight rays all the time as shafts of sunlight penetrate evening clouds and haze.  The “airless Moon” shouldn’t have such rays, yet the men of Apollo clearly saw them.

NASA uses Meteoric Dust to map the Atmosphere

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Heliophysics nuggets are a collection of early science results, new research techniques, and instrument updates that further our attempt to understand the sun and the dynamic space weather system that surrounds Earth.

On August 11th and 12th, 2013, the annual Perseid meteor shower will peak, filling the sky with streaks of light, commonly known as shooting stars. Such visually stunning showers are actually but the tip of the iceberg when it comes to meteoroids slamming into Earth’s atmosphere: Some 10 to 40 tons of material of invisible meteoric dust enters the atmosphere from interplanetary space every day.

Larger meteoroids cause bright flashes of light when they hit Earth's atmosphere, such as this fireball caught during the Perseid meteor shower Aug. 12, 2006. The bulk of meteoric activity is much less showy: Some 10 to 40 tons of meteor dust enter our atmosphere every day. (Image Credit: Courtesy of Pierre Martin)

American Heart Association says Elevated blood pressure increasing among Children, Adolescents

 

American Heart AssociationDallas, TX – The risk of elevated blood pressure among children and adolescents rose 27 percent during a thirteen-year period, according to new research in the American Heart Association journal Hypertension.

Higher body mass, larger waistlines and eating excess sodium may be the reasons for the elevated blood pressure readings, researchers said.

High blood pressure is a risk factor for stroke, heart disease and kidney failure — accounting for about 350,000 preventable deaths a year in the United States.

American Heart Association says Institute of Medicine (IOM) report an incomplete review of Sodium’s Impact

 

American Heart AssociationDallas, TX – The American Heart Association says a new report from the Institute of Medicine (IOM) — Sodium Intake in Populations: Assessment of Evidence — is incomplete in its assessment of sodium’s impact on health because it does not focus its examinations on scientific evidence that links excess consumption and high blood pressure.

The report found that though reducing sodium intakes from current levels is important, and that there is a positive relationship between higher levels of sodium intake and risk of heart disease, there is not enough evidence to conclude that sodium reduction below 2,300 mg daily leads to less heart disease, stroke and a reduced risk of death.

American Heart Association says alternative therapies may help lower blood pressure

 

Due to their modest effects, alternative therapies can be used with — not as a replacement for — standard treatment.

American Heart AssociationDallas, TX – Alternative therapies such as aerobic exercise, resistance or strength training, and isometric hand grip exercises may help reduce your blood pressure, according to the American Heart Association.

In a new scientific statement published in its journal Hypertension, the association said alternative approaches could help people with blood pressure levels higher than 120/80 mm Hg and those who can’t tolerate or don’t respond well to standard medications.

NASA answers the question, “Is There an Atmosphere on the Moon?”

 

Written by Brian Day
NASA’s Ames Research Center

NASA - National Aeronautics and Space AdministrationMoffett Field, CA – Until recently, most everyone accepted the conventional wisdom that the moon has virtually no atmosphere.

Just as the discovery of water on the moon transformed our textbook knowledge of Earth’s nearest celestial neighbor, recent studies confirm that our moon does indeed have an atmosphere consisting of some unusual gases, including sodium and potassium, which are not found in the atmospheres of Earth, Mars or Venus.

It’s an infinitesimal amount of air when compared to Earth’s atmosphere.

American Heart Association reports most pre-packaged meals, snacks for toddlers contain too much salt

 

American Heart AssociationNew Orleans, LA – Nearly 75 percent of commercial pre-packaged meals and savory snacks for toddlers are high in sodium, according to research presented at the American Heart Association’s Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions.

In the first study to look at the sodium content in U.S. baby and toddler foods, researchers compared the sodium content per serving of 1,115 products for babies and toddlers using data on major and private label brands compiled by the U.S. Centers for Disease Control (CDC).

Some toddler meals had as much as 630 mg of sodium per serving. (Courtesy American Heart Association)

American Heart Association reports Adults worldwide eat almost double daily AHA-recommended amount of sodium

 

The study is the first to provide information about sodium intake by country, age and gender.

American Heart AssociationNew Orleans, LA – Seventy-five percent of the world’s population consumes nearly twice the daily recommended amount of sodium (salt), according to research presented at the American Heart Association’s Nutrition, Physical Activity and Metabolism and Cardiovascular Disease Epidemiology and Prevention 2013 Scientific Sessions.

Global sodium intake from commercially prepared food, table salt, salt and soy sauce added during cooking averaged nearly 4,000 mg a day in 2010.
