Health and lifestyle researchers have found that high consumption of fruit and vegetables is linked to lowered odds of memory loss and its co-morbid heart disease.

For the study, published in the International Journal of Public Health, the researchers studied data from 1,39,000 older Australians and found strong links between certain food groups, memory loss and co-morbid heart disease or diabetes.

The study found that higher consumption of protein-rich foods was associated with a better memory.

“Our present study implies that the healthy eating suggestions of cereals consumption in the prevention of memory loss and co-morbid heart disease for older people may differ compared to other age groups,” said the study’s researcher Luna Xu from the University of Technology, Sydney, in Australia.

She said the study pointed to a need for age-specific healthy dietary guidelines.

Memory loss is one of the main early symptoms for people with dementia, which is the second leading cause of death of Australians.

People living with dementia have on average between two and eight co-morbid conditions, which may accelerate cognitive and functional impairment.

The most common comorbidities in dementia include cardiovascular diseases, diabetes and hypertension.

“The dietary intervention in chronic disease prevention and management, by taking into consideration the fact that older populations often simultaneously deal with multiple chronic conditions, is a real challenge,” Xu said.

“To achieve the best outcome for our ageing population, strong scientific evidence that supports effective dietary intervention in preventing and managing co-occurring chronic conditions, is essential,” Xu added. (IANS)

Bedroom Air Filters Can improve Breathing in Asthmatic Children: Study

For the results, the researchers conducted the double-blind crossover study in a Shanghai suburb during a period of moderately high PM2.5 pollution in 2017

Using a bedroom air filter that traps fine particles of pollution with diameters smaller than 2.5 micrometres can significantly improve breathing in asthmatic children, according to a new study.

Fine particulate matter (PM2.5) is a ubiquitous air pollutant originating from fossil fuel emissions, wildfires and other biomass burning, industrial sources, and gasoline- and diesel-powered vehicles. Thirty times smaller in diameter than a human hair, the particles are easily inhaled and can penetrate deep into the small, or lower, airways where they can trigger or exacerbate asthma symptoms. Inhalers don’t help since they are only designed to open upper airways.

The findings, published in the journal JAMA Pediatrics, documented physiological improvements occur in the child’s airways when air filters are in use, and it suggests that with consistent use, the filters may help prevent, not just alleviate asthmatic flare-ups.

“Our results show that using an air purifier to reduce the exposure of lower airways to pollutants could help asthmatic children breathe easier without those costly drugs,” said study researcher Junfeng Zhang from Duke University in the US.

For the results, the researchers conducted the double-blind crossover study in a Shanghai suburb during a period of moderately high PM2.5 pollution in 2017. They gave 43 children with mild to moderate asthma two air filters to use in their bedrooms. One was a high-efficiency particulate air (HEPA) filter capable of removing PM2.5; the other was a sham filter.

Each filter was used for two weeks in random order with a two-week interval in between. Neither the children nor their families knew which filter was which. “Results showed that PM2.5 concentrations inside the children’s bedrooms were a third to two-thirds lower when the real air filters were in use than when the sham ones were being used,” said researcher Michael H Bergin.

This drop coincided with significant improvements in how easily air flowed in and out of the children’s small airways and lungs, Bergin said. These improvements included a 24 per cent average reduction in total airway resistance, a 43.5 per cent average reduction in small airway resistance, a 73.1 per cent average increase in airway elasticity, and a 27.6 per cent average reduction in exhaled nitric oxide, a biomarker of lung inflammation.

Although the benefits lasted only as long as the real air filters were in use, “it’s probable that if children use the filters on an ongoing daily basis they will see continued benefits,” Zhang said. (IANS)
