Additives do not boost milk nutrition

A new study has revealed that milk boasting added calcium, vitamin D, or omega-3 fatty acids, are unlikely to boost nutrition. The research led by consumer group choice showed that generic supermarket milk delivers the same nutritional benefits but for half the price.

Comparing up to 100 of the leading milk brands, including organics, the researchers found that those, which marketed low-saturated fats, only had a negligible difference.

For milk boasting Omega-3 fats, an individual has to drink two litres to get the same benefit as eating a 50g portion of salmon. However, the only real difference in milk was the fat content, which is how full-cream, low-fat and skim are divided.

The study showed that full cream milk must have at least 3.2 per cent fat, light milk no more than 1.5 per cent, while skim contains less than 0.1 per cent fat. It added all the tested milks were a good source of calcium, of between 115mg and 120mg of calcium per 100ml.

New therapy for heart failure

A major international study has found that a therapy called cardiac resynchronisation can significantly delay the progression of heart failure. In the study, researchers found that the treatment reduced the risk of serious heart failure events by 41 per cent.

“This shows, for the first time, that the onset of heart failure symptoms and hospitalisation for heart failure can be delayed with pacing therapy,” said David Wilber, director, Cardiovascular Institute at Loyola University Chicago Stritch School of Medicine.

A device implanted in the upper chest delivers electrical impulses that help synchronise contractions of the left ventricle, the heart’s main pumping chamber.

Effects of bullying on sleep

Exposure to workplace bullying is associated with increased sleep disturbances, according to a new study. A study claims association between observed bullying and sleep disruption, indicating that bullying has unfavourable effects even when it is experienced indirectly.

It also helps reveal the prevalence of workplace bullying, with 11 per cent of women and nine per cent of men facing ‘hostile behaviour’ in their jobs at least weekly and for at least six months during the previous 12 months.

The other factors such as age, occupation, weekly work hours and depressive symptoms were taken into account too, but yet it was found that exposure to bullying was significantly associated with self-reported sleep disturbances.

Breathalyser helps spot lung cancer

Israeli scientists have come up with a device that can help spot lung cancer molecules on the breath of patients. Hossam Haick and colleagues at Technion-Israel Institute of Technology in Haifa think that the technology may lead to pocket-friendly, portable breath-test devices with the potential to save large numbers of lives by detecting cancer early.

“Our results show great promise for fast, easy and cost-effective diagnosis and screening of lung cancer,” said Haick. “The developed devices are expected to be relatively inexpensive, portable, and amenable to use in widespread screening, making them potentially valuable in saving millions of lives every year,” he added.
