Resveratrol may hinder effects of exercise, study suggests

Resveratrol, a compound in red wine, has been heralded in past studies for health benefits such as lowering blood pressure and slashing heart disease risk. But one of its supposed perks— enhancing the effects of exercise— has been challenged in new research.

According to a small study published in the November 2014 issue of the journal Applied Physiology, Nutrition and Metabolism, resveratrol (RSV) may impede the body’s response to physical training.

“The easiest way to experience the benefits of physical activity is to be physically active,” Dr. Brendon Gurd, a kinesiology and health studies professor at Queen’s University in Canada, said in a news release. “The efficacy of RSV at improving metabolic and
cardiovascular functions is not as profound as once thought.”

 

Scientists create ‘feel fuller’ food ingredient

British scientists have developed an ingredient that makes foods more filling, and say initial tests in overweight people showed that it helped prevent them gaining more weight.

The ingredient, developed by researchers at London’s Imperial College and at the University of Glasgow, contains propionate, a natural substance that stimulates the gut to release hormones that act on the brain to reduce hunger.

 

Scientists find second, ‘hidden’ language in human genetic code

U.S. geneticists say a second code hiding within DNA changes how scientists read its instructions and interpret mutations to make sense of health and disease.

Since the genetic code was deciphered in the 1960s, scientists have assumed it was used exclusively to write information about proteins, but University of Washington scientists say they’ve discovered genomes use the genetic code to write two separate “languages.”

 

Scientists find why male smokers may run even higher health risks

Male smokers are three times more likely than non-smoking men to lose their Y chromosomes, according to research which may explain why men develop and die from many cancers at disproportionate rates compared to women.

In a study in the journal Science, researchers at Sweden’s Uppsala University found that Y chromosomes, which are important for sex determination and sperm production, more often disappear from blood cells of smokers than those of men who have never smoked or of men who have kicked the habit.

“There is a correlation between a common and avoidable risk factor, that is smoking, and the most common human mutation — loss of the Y chromosome,” said Jan Dumanski, an Uppsala professor who worked on the study.

“This … may in part explain why men in general have a shorter life  span than women and why smoking is more dangerous for men.”

 

Seen At 11: Daylight Saving Time Can Be A Danger To Your Health

“Our body has a natural circadian rhythm which is almost an internal clock that regulates our 24-hour cycle. It regulates our sleep-wake cycle and that can be disturbed fairly easily,” said neuro-psychiatrist Dr. Julia Samton.  According to Samton, even moving the clocks just one hour may mean disrupted sleep patterns, and more, for some people.

 

Serious reading takes a hit from online scanning and skimming, researchers say

Claire Handscombe has a commitment problem online. Like a lot of Web surfers, she clicks on links posted on social networks, reads a few sentences, looks for exciting words, and then grows restless, scampering off to the next page she probably won’t commit to.

“I give it a few seconds — not even minutes — and then I’m moving again,” says Handscombe, a 35-year-old graduate student in creative writing at American University.

But it’s not just online anymore. She finds herself behaving the same way with a novel.

“It’s like your eyes are passing over the words but you’re not taking in what they say,” she confessed. “When I realize what’s happening, I have to go back and read again and again.”

Sitting comfortably? You won’t be after reading this: Cankles, constipation and even ‘brain fog’ – why we should all try to spend a lot less time on our bottoms

With many of us chained to a desk for hours a day before heading home to slump in front of the telly, we’re spending much of our time on our bottoms.

And it’s having an impact on our health, a growing body of evidence suggests.

Last month, for instance, it emerged that spending an extra hour sitting a day (for 13, rather than 12, hours) is linked to a 50 per
cent greater risk of being disabled. And this was regardless of whether the participants – all over 60 – also did moderate exercise,
according to the U.S. study published in the Journal of Physical Activity & Health.

 

What exactly is evaporated cane juice?

It’s been gracing food labels for years, but more recently, it’s also prompted a tsunami of civil litigation against firms from Chobani to Trader Joe’s . So what exactly is ‘evaporated cane juice’ (ECJ), and does the name accurately reflect what it actually is.

 

Study casts doubt on whether extra vitamin D prevents disease

Researchers cast doubt on the prevailing wisdom that vitamin D supplements can prevent conditions like cancer, diabetes and heart disease, saying on Friday low vitamin D may be a consequence, not a cause, of ill health.

The findings could have implications for millions of people who take vitamin D pills and other supplements to ward off illness – Americans spend an estimated $600 million a year on them alone.
