WHAT'S THE BUZZ

What makes one use bottled water

Most people believe that bottled water is healthier than tap water, a new research has found.
However, such individuals are unaware of the exact benefits of consuming packed water but think they don’t make much of a difference.
Lorna Ward led a team of researchers from the University of Birmingham who carried out interviews with users of the university’s sports centre.
They found that convenience and taste — not health — were the main motivating factors for choosing bottled water.
“The majority of participants believed that bottled water has some health benefits, but that they were not necessarily significant or superior to the benefits provided by tap water. Convenience and taste were more influential factors for participants when deciding to buy a bottle of water.”
Bottled water was described as being more ‘pure’ than tap water, and was also described as containing more ‘minerals’.
However, the most commonly cited reason for purchasing bottled water was convenience.

Vitamin D vital for losing weight

Researchers have revealed that measuring vitamin D levels before the start of a low-calorie diet can help predict weight loss success.
“Vitamin D deficiency is associated with obesity, but it is not clear if inadequate vitamin D causes obesity or the other way around,” said lead author Dr Shalamar Sibley, University of Minnesota.
During the study, the authors attempted to determine whether baseline vitamin D levels before calorie restriction affect subsequent weight loss.
They measured the circulating blood levels of vitamin D in 38 overweight men and women before and after the subjects followed a diet plan for 11 weeks consisting of 750 calories a day fewer than their estimated total needs.
The authors found that baseline, or pre-diet, vitamin D levels predicted weight loss in a linear relationship.

Less fit adults may develop diabetes
Young adults who have low aerobic fitness levels are two to three times more likely to develop diabetes in middle age, finds a new study.
“These young adults are setting the stage for chronic disease in middle age by not being physically active and fit,” said Mercedes Carnethon, lead author, Northwestern’s Feinberg School.
“People who have low fitness in their late teens and 20s tend to stay the same later in life or even get worse. Not many climb out of that category,” Carnethon added.
The study focussed on the relationship between aerobic fitness, measured by treadmill test and development of diabetes. Carnethon insists that unfit young adults can avoid a future with diabetes by exercising and losing weight.
“Improving your fitness through physical activity is one way you can modify your body fat,” she said.

Ras protein may fight against itself

Scientists at Tel Aviv University (TAU) in Israel have found that a cancer-causing protein can also help fight tumours it causes.
The researchers have shown that an oncogene called Ras — which can cause normal cells to be come cancerous when mutated or expressed in high concentrations — has the power to heal as well as harm.
Oded Rechavi and his fellow researchers at the university’s department of neurobiology have found that Ras has the ability to transfer from cancer cells into immune cells — such as T-cells — a transfer that may be the key to creating new drugs to fight cancerous tumours.
