Stretching more effective than walking to lower high blood pressure: USask study

by

A new University of Saskatchewan (USask) study has found that stretching is superior to brisk walking for reducing blood pressure in people with high blood pressure or who are at risk of developing elevated blood pressure levels.

Walking has long been the prescription of choice for physicians trying to help their patients bring down their blood pressure. High blood pressure (hypertension) is a leading risk factor for cardiovascular disease and among the top preventable risk factors affecting overall mortality.

This new finding, published December 18, 2020 in the Journal of Physical Activity and Health, shows that stretching should be part of a well-rounded treatment plan for people wrestling with hypertension.

BfR consumer monitor special superfoods

by

The term “superfood” is not legally regulated. Superfoods, however, are often referred to as foods whose ingredients are considered particularly beneficial to health – for example, due to their high content of vitamins or minerals and fibre. Only 8 percent of respondents associate health risks with the consumption of superfoods.

“Superfood products are often not sufficiently investigated to be able to evaluate them from a health perspective,” says BfR President Professor Dr Andreas Hensel.

“A balanced and varied diet remains the best basis for staying healthy. This can be supported by the consumption of imported superfoods just as by the consumption of local fruits and vegetables.” [Read more…] about BfR consumer monitor special superfoods

Tackling food allergies at the source

by

Food allergies are a big problem. About 7% of children and 2% of adults in the U.S. suffer from some kind of food allergy. These allergies cost a whopping $25 billion in health care each year. Then there’s the time lost at school or work. And there’s the risk of serious complications, even death.

It’s critical to find ways to reduce the suffering caused by food allergies. Food processing companies already spend a lot of effort to label products so people can avoid items they’re allergic to. But what if we could do better? What if we could enjoy the foods we like without worrying they might trigger a health crisis? [Read more…] about Tackling food allergies at the source

Weight loss shouldn’t be the goal of PE

by

For adults, the goal of exercise is often to shed some pounds, but new research from the University of Georgia suggests the objective should be different for kids.

Physical education should focus on improving students’ physical skills, knowledge of the benefits of exercise and motivation to be active.

The goal should be to build students’ cardiorespiratory endurance, a measure of how well the body handles long periods of exercise – not to help them lose weight, according to the study’s authors. [Read more…] about Weight loss shouldn’t be the goal of PE

Go (over) easy on the eggs: ‘Egg-cess’ consumption linked to diabetes

by

Scrambled, poached or boiled, eggs are a popular breakfast food the world over. Yet the health benefits of the humble egg might not be all they’re cracked up to be as new research from the University of South Australia shows that excess egg consumption can increase your risk of diabetes.

Conducted in partnership with the China Medical University, and Qatar University, the longitudinal study (1991 to 2009) is the first to assess egg consumption in a large sample of Chinese adults.

It found that people who regularly consumed one or more eggs per day (equivalent to 50 grams) increased their risk of diabetes by 60 per cent. [Read more…] about Go (over) easy on the eggs: ‘Egg-cess’ consumption linked to diabetes

Physical distancing policies ‘not enough to protect lower-income people’

by

A new Boston University School of Public Health study of the first four months of America’s coronavirus epidemic, published in the journal Nature Human Behaviour, shows that physical distancing (also called “social distancing”) policies had little effect on lower income people still needing to leave their homes to go to work – but does show them staying home when they could.

“If lower-income people were simply ignoring the trend towards physical distancing, we would have expected them to continue going to places like supermarkets, liquor stores, and parks at the same rates as before. Instead, their visits dropped at almost the same rates as the very highest-income group,” says study lead author Dr Jonathan Jay, assistant professor of community health sciences at BUSPH.

“This indicates that lower income people were just as aware and motivated as higher-income people to protect themselves from COVID-19, but simply couldn’t stay home as much because they needed to go to work,” he says.

Coming out as bisexual associated with increased risk of smoking

by

For many years, lesbian, gay, bisexual, and other non-heterosexual (LGB+) folks have been known to be more likely to smoke than their straight counterparts.

But a new, first-of-its-kind Boston University School of Public Health (BUSPH) study paints a more precise picture by looking at LGB+ identities separately and over time, finding that bisexuality is the identity most associated with smoking, especially around the time of coming out.

Published in the journal JAMA Pediatrics, the nationally-representative cohort study followed 7,843 youth and young adults over three years, finding that those who came out as bisexual were twice as likely as consistently-heterosexual participants to start smoking.

Study measures effectiveness of different face mask materials when coughing

by

A team of researchers have tested everything from t-shirts and socks to jeans and vacuum bags to determine what type of mask material is most effective at trapping the ultrafine particles which may contain viruses such as SARS-CoV-2, the virus which causes Covid-19.

The researchers, from the University of Cambridge and Northwestern University, tested the effectiveness of different fabrics at filtering particles between 0.02 and 0.1 micrometres – about the size of most viruses – at high speeds, comparable to coughing or heavy breathing. They also tested N95 and surgical masks, which are more commonly used in healthcare settings.

Previous studies have only looked at a small selection of fabrics when the wearer is breathing normally, when particles are expelled at lower speed. Studying more fabrics and testing them at higher speeds provides a more robust evidence base for the effectiveness of fabric masks.

Is sitting always bad for your mind? A new study suggests maybe not

by

It’s generally accepted health advice that adults of all ages should sit less, move more, and engage in regular exercise to feel better and reduce the risk of chronic diseases.

However, when it comes to the brain and cognition, a new study of older adults from Colorado State University suggests that some sedentariness isn’t all bad, so long as basic physical activity benchmarks are being met.

The research, from Assistant Professor Aga Burzynska in the CSU Department of Human Development and Family Studies, examined the association between sensor-measured physical activity and cognitive performance in a sample of 228 healthy older adults, aged 60 to 80.
