Researchers found that the more people exercise, the less their
blood pressure will rise in response to a high-salt diet. "For
those with low physical activity, their blood pressure will
increase more if they increase their sodium intake," said study
co-author Dr. Jiang He, chair of the department of epidemiology at
the Tulane University School of Public Health and Tropical Medicine
in New Orleans.
"It's a little bit of a surprise," He added. "But this is the first
study to look at this particular association between physical
activity and salt sensitivity and blood pressure. But after
thinking it over it makes sense, because we already know that
physical activity will reduce blood pressure."
Airway inflammation in chronic obstructive pulmonary disease (COPD)
is believed to be insensitive to corticosteroids. However,
corticosteroids are recommended in COPD (GOLD stages III, IV) with
frequent exacerbations. Resveratrol has anti-inflammatory
properties and could be an alternative to corticosteroids in COPD
therapy. We investigated the effect of dexamethasone versus
resveratrol on the release of COPD-related inflammatory mediators
(IL-6, IL-8, GM-CSF, MCP-1) and...
According to research conducted in Australia, too much television and not enough exercise causes artery damage in children as young as six. The study found that those children who spent longest in front of the TV had narrowed eye blood vessels, evidence of increased heart disease risk. Researcher Dr Bamini Gopinath said replacing an hour of TV a day with exercise would combat the problem. 21/04/2011 The Sun By: Presswatch
Researchers at Durham University have found that the longer a child
is breastfed, the bigger the size of their brain, and that there is
a direct correlation between the size of a mammal's brain and the
amount of time they suckle. The scientists were not sure whether it
was the energy that milk supplied or the nutrients that made the
difference. The team studied 128 mammal species, including humans.
They found that the length of the gestation and suckling periods
affected the size of the brain...
Children who get into a car more than an hour after a parent has
put out a cigarette still face a threat to their health, a study
shows. Experts are warning parents that they are wrong to believe
that opening car windows and stubbing out cigarettes before the
children climb in will protect them. Julie Barratt, from the
Chartered Institute of Environmental Health which carried out the
study, said: "Don't kid yourself that because you cannot see the
smoke, it is not there doing harm. Children are...
Trends in weight gain have paralleled trends in intake of added
sugars, according to a review of 27 years of Minnesota Heart Survey
data presented at an American Heart Association (AHA) event.
The AHA’s Nutrition, Physical Activity and
Metabolism/Cardiovascular Disease Epidemiology and Prevention 2011
Scientific Sessions took place in San Diego, California earlier
this month.
The researchers, from the University of Minnesota in
Minneapolis, found that consumption of added sugars...
After decades of epidemiological, clinical and experimental
research, it has become clear that consumption of Mediterranean
dietary patterns rich in olive oil have a profound influence on
health outcomes, including obesity, metabolic syndrome (MetS) and
diabetes mellitus. Traditionally, many beneficial properties
associated with this oil have been ascribed to its high oleic acid
content. Olive oil, however, is a functional food that, besides
having high-monounsaturated (MUFA) content, contains...
Chinese research suggests that eating a regular breakfast may reduce the risk of lead poisoning in children, finding that blood levels of lead were 15 per cent lower in those who did not skip breakfast. Previous studies have shown that an empty stomach increases the body's absorption of lead, and eating breakfast was also associated with greater zinc blood levels, which helps strengthen the immune system. -- Daily Telegraph, March 31, 2011
