(Press-News.org) Short-terms clinical trials have demonstrated the health benefits of low-carbohydrate diets (LCDs) and low-fat diets (LFDs) for weight loss and heart protection. Now a study published in the Journal of Internal Medicine looks at the effects of these diets on mortality in middle-aged and older adults.
In the study of 371,159 individuals aged 50 to 71 years, 165,698 deaths occurred over a median follow-up of 23.5 years.
A healthy LFD—characterized by low intake of saturated fat and high intakes of plant protein and high-quality carbohydrates—was related to fewer deaths from all causes, from cardiovascular diseases, and from cancers. In contrast, an overall LCD and an unhealthy LCD were associated with significantly higher total, cardiovascular, and cancer mortality rates. A healthy LCD was associated with slightly lower death rates.
“Our results support the importance of maintaining a healthy LFD with less saturated fat in preventing all-cause and cause-specific mortality among middle-aged and older people,” the authors wrote.

Research reveals an increase in the range of invasive American mink in Europe
2023-05-03
The American mink Neogale vison is an invasive species in Europe introduced for fur farming in the 1920s and later established in the wild after escapes and illegal releases. As a feral species, it threatens native species and biodiversity, and poses a risk for boosting disease circulation, including mink-related strains of COVID-19. New research published in Mammal Review provides information on the presence of the species in Europe over the past 15 years.
The study, which was conducted by an international team of scientists, compiled a diverse set of data resources covering 32 nations. The work uncovers a progressive spread of the American mink in most ...
Can internet usage help protect against dementia?
2023-05-03
New research published in the Journal of the American Geriatrics Society found a link between regular use of the internet and a lower risk of dementia.
For the study, investigators followed 18,154 dementia-free adults aged 50 to 64.9 years for a median of 7.9 years and a maximum of 17.1 years. During follow-up, 4.68% of participants were diagnosed with dementia.
Regular internet usage was associated with approximately half the risk of dementia compared with non-regular usage. This link was found regardless of educational attainment, race-ethnicity, sex, and generation.
“Online engagement may help to develop and maintain cognitive reserve, which ...
How well do face masks worn by children block the release of exhaled particles?
2023-05-03
New research published in Pediatric Investigation provides evidence that face masks reduce the release of exhaled particles when used by school-aged children.
For the study, 23 healthy children were asked to perform activities that ranged in intensity (breathe quietly, speak, sing, cough, and sneeze) while wearing no mask, a cloth mask, or a surgical mask.
The production of exhaled particles that were 5 μm or smaller, which is the dominant mode of transmission of many respiratory viruses, increased with coughing and sneezing. Face masks—especially surgical face masks—effectively reduced the release of ...
How does glucocorticoid therapy affect the developing cardiovascular system during pregnancy?
2023-05-03
Glucocorticoid therapy is widely used during pregnancies at risk of premature delivery to promote fetal lung maturation. While it is an effective treatment, it can also trigger heart and blood vessel problems. New research published in The FASEB Journal uncovers the mechanisms behind the cardiovascular-related effects of the most commonly used glucocorticoids, Dexamethasone (Dex) and Betamethasone (Beta).
When investigators treated chicken embryos with these different glucocorticoids, they found that both caused growth restriction, with Beta being more severe. At the level ...
Cigarette butts leak deadly toxins into the environment
2023-05-03
Cigarette filters are the world’s most common form of litter. Researchers from the University of Gothenburg can now show that the filters leak thousands of toxins and plastic fibres that are toxic to aquatic larvae. The researchers are therefore calling for these filters to be completely banned.
On the footpath, at the bus stop, in the park and on the beach. You can hardly avoid seeing cigarette butts in the streetscape. And these butts aren’t just butt-ugly to behold – they’re also really bad for the environment. A research ...
Study questions long term beta blocker use to curb further heart attack risk
2023-05-03
The accepted clinical practice of using beta blockers over the long term to curb the risk of further heart attacks or death doesn’t seem to be warranted in patients who don’t have heart failure, suggests a large study published in the journal Heart.
The researchers found no difference in these risks between patients taking beta blockers more than a year after their heart attack and those who weren’t on these drugs.
Beta blockers are a class of drugs that are predominantly used to manage abnormal heart rhythms, ...
Fresh hope for Australians living with chronic back pain
2023-05-03
Long-term sufferers of chronic back pain experienced dramatic reductions in pain and related disability that remained at their one-year follow-up after taking part in a new treatment tested by Curtin-Macquarie-Monash University research.
Published today in the leading medical journal The Lancet, the research found large clinically significant improvements in the intensity of pain and pain-related disability among almost 500 people who had been seeking help for their pain for an average of four years before trialling the new treatment.
The treatment, which delivered a healthcare and work productivity saving of more than $5000 per person, took a whole-person approach ...

Why mosses are vital for the health of our soil and Earth
2023-05-03
Some people see moss growing in their gardens as a problem, but what they may not realise is this ancient ancestor of all plants is bringing lots of benefits to our green spaces, such as protecting against erosion.
Now a massive global study led by UNSW Sydney has found mosses are not just good for the garden, but are just as vital for the health of the entire planet when they grow on topsoil. Not only do they lay the foundations for plants to flourish in ecosystems around the world, they may play an important role mitigating against climate change by capturing ...
