Vitamin E in canola, other oils hurts lungs

Posted: 20 May 2014 07:04 PM PDT

A large new study advances our understanding of vitamin E and ties increasing consumption of supposedly healthy, vitamin E-rich oils -- canola, soybean and corn -- to the rising incidence of lung inflammation and, possibly, asthma. The good news: vitamin E in olive and sunflower oils improves lungs. The study shows drastically different health effects of vitamin E depending on its form: gamma-tocopherol in soybean, canola and corn oil and alpha-tocopherol in olive and sunflower oils.

Adults who lose weight at any age could enjoy improved cardiovascular health

Posted: 20 May 2014 03:48 PM PDT

Weight loss at any age in adulthood is worthwhile because it could yield long-term heart and vascular benefits, suggests new research. For the first time, the findings indicate that adults who drop a BMI category -- from obese to overweight, or from overweight to normal -- at any time during adult life, even if they regain weight, can reduce these cardiovascular manifestations.

Chronic insufficient sleep increases obesity, overall body fat in children

Posted: 20 May 2014 10:43 AM PDT

One of the most comprehensive studies of the potential link between reduced sleep and childhood obesity finds compelling evidence that children who consistently received less than the recommended hours of sleep during infancy and early childhood had increases in both obesity and in adiposity or overall body fat at age 7.

Full serving of protein at each meal needed for maximum muscle health

Posted: 20 May 2014 10:32 AM PDT

Most Americans eat a diet that consists of little to no protein for breakfast, a bit of protein at lunch and an overabundance of protein at dinner. As long as they get their recommended dietary allowance of about 60 grams, it's all good, right? Not according to new research from a team of scientists led by a muscle metabolism expert.

Physical activity can protect overweight women from risk for heart disease

Posted: 20 May 2014 10:28 AM PDT

For otherwise healthy middle-aged women who are overweight or obese, physical activity may be their best option for avoiding heart disease, according to a study that followed nearly 900 women for seven years. "Being overweight or obese increases a person's risk for developing conditions such as hypertension, elevated triglyceride levels and elevated fasting glucose levels—all of them risk factors for heart disease, the leading cause of death in the U.S.," said the study's lead author.

Pregnant women respond to music with stronger physiological changes in blood pressure

Posted: 20 May 2014 09:35 AM PDT

Pregnant women, compared to their non-pregnant counterparts, rate music as more intensely pleasant and unpleasant, associated with greater changes in blood pressure, a study has demonstrated. Music appears to have an especially strong influence on pregnant women, a fact that may relate to a prenatal conditioning of the fetus to music.

Better bedbug trap: Made from household items for about $1

Posted: 20 May 2014 09:30 AM PDT

The contraption seems so simple, yet so clever, like something The Professor might have concocted on "Gilligan's Island." Researchers have devised a bedbug trap that can be built with household items. All you need are two disposable plastic containers, masking tape and glue, said an urban entomology professor. The traps catch and collect the bugs when they try to travel between people and the places where bedbugs hide, he said.

E-cigarette use for quitting smoking associated with improved success rates

Posted: 20 May 2014 07:04 AM PDT

People attempting to quit smoking without professional help are approximately 60 percent more likely to report succeeding if they use e-cigarettes than if they use willpower alone or over-the-counter nicotine replacement therapies such as patches or gum, finds a large survey of smokers. The study surveyed 5,863 smokers between 2009 and 2014 who had attempted to quit smoking without the aid of prescription medication or professional support. 20% of people trying to quit with the aid of e-cigarettes reported having stopped smoking conventional cigarettes at the time of the survey.

Harmful bacteria can linger on airplane seat-back pockets, armrests for days

Posted: 20 May 2014 07:04 AM PDT

Disease-causing bacteria can linger on surfaces commonly found in airplane cabins for days, even up to a week, according to research. In order for disease-causing bacteria to be transmitted from a cabin surface to a person, it must survive the environmental conditions in the airplane. In this study, MRSA lasted longest (168 hours) on material from the seat-back pocket while E. coli O157:H7 survived longest (96 hours) on the material from the armrest.

Testing paleo diet hypothesis in test tubes: Surprising relationships between diet and hormones that suppress eating

Posted: 20 May 2014 06:35 AM PDT

By comparing how gut microbes from human vegetarians and grass-grazing baboons digest different diets, researchers have shown that ancestral human diets, so called 'paleo' diets, did not necessarily result in better appetite suppression. The study reveals surprising relationships between diet and the release of hormones that suppress eating.

Little exercise, heavy use of electronic media constitute a significant health risk for children

Posted: 20 May 2014 06:34 AM PDT

Low levels of physical activity combined with heavy use of electronic media and sedentary behavior are linked to an increased risk for type 2 diabetes and vascular diseases already in 6-8 year-old children, a study concludes. The study showed that low levels of physical activity - and unstructured physical activity in particular - are linked to increased risk factors serious health problems. Heavy use of electronic media, and especially watching too much TV and videos, was linked to higher levels of risk factors in children.

More activity: Less risk of gestational diabetes progressing to type 2 diabetes

Posted: 19 May 2014 02:09 PM PDT

Increased physical activity among women who had gestational diabetes mellitus can lower the risk of progression to type 2 diabetes mellitus. The authors examined the role of physical activity, television watching and other sedentary activity, along with changes in these behaviors, in the progression to type 2 diabetes mellitus.

Exposure to air pollution during second trimester of pregnancy may be associated with increased asthma risk in children

Posted: 19 May 2014 08:42 AM PDT

Children who are exposed in utero to high levels of particulate air pollution during the second trimester of pregnancy may be at greater risk of developing asthma in early childhood, according to a new study. The study included 430 full-term children followed to age 7 years and their mothers. Daily exposure to air pollution from sources including traffic, power plants, and other industrial sources consisting of fine particles in the prenatal period was estimated based on where these mothers lived.

Fluoridating water does not lower IQ, study concludes

Posted: 19 May 2014 08:01 AM PDT

Fluoridating water does not adversely affects children's mental development and adult IQ, new research concludes. The researchers were testing the contentious claim that exposure to levels of fluoride used in community water fluoridation is toxic to the developing brain and can cause IQ deficits. "Our findings will hopefully help to put another nail in the coffin of the complete canard that fluoridating water is somehow harmful to children's development," researchers noted.

For pregnant smokers, vitamin C supplements improve lung function of newborn

Posted: 19 May 2014 06:31 AM PDT

Supplemental vitamin C taken by pregnant smokers improved measures of lung function for newborns and decreased the incidence of wheezing for infants through 1 year, according to a study. The researchers found that newborns of women randomized to vitamin C, compared with those randomized to placebo, had improved measures of pulmonary function.

Use of air conditioners increases nighttime temperatures, escalates demand for air conditioning

Posted: 16 May 2014 05:27 PM PDT

Releasing excess heat from air conditioners running during the night resulted in higher outside temperatures, worsening the urban heat island effect and increasing cooling demands, a study has found. The paper focuses on the anthropogenic contribution of air conditioning systems on air temperature, and examines the electricity consumption for the rapidly expanding Phoenix metropolitan area, one of the largest metropolitan area in the US. Phoenix is located within the semiarid Sonoran desert and because of its harsh summertime conditions makes considerable use of air conditioning systems.
