Edition 25: Wary Of Fat? Milk Might Help

Women who drank two large glasses of milk daily after their weight-lifting routine gained more muscle and lost more fat compared to women who drank sugar-based energy drinks, says a new study.
'Resistance training is not a typical choice of exercise for women,' says Stu Phillips, professor in kinesiology (study of human movement) at McMaster University.
'But the health benefits of resistance training are enormous: It boosts strength, bone, muscular and metabolic health in a way that other types of exercise cannot.'

A previous study conducted by Phillips' lab showed that milk increased muscle mass and fat loss in men.
This new study, says Phillips, was more challenging because women not only steer clear of resistance training, they also tend to steer away from dairy products based on the incorrect belief that dairy foods are fattening.
'We expected the gains in muscle mass to be greater, but the size of the fat loss surprised us,' says Phillips.
'We're still not sure what causes this but we're investigating that now. It could be the combination of calcium, high-quality protein, and vitamin D may be the key, and conveniently, all of these nutrients are in milk,' said Phillips.
Over a 12-week period, the study monitored young women who did not use resistance-training exercise.
Every day, two hours before exercising, the women were required not to eat or drink anything except water.
Immediately after their exercise routine, one group consumed half litre of fat free white milk; the other group consumed a similar-looking but sugar-based energy drink. The same drinks were consumed by each group one hour after exercising.
The training consisted of pushing (e.g. bench press, chest fly), pulling (e.g. seated lateral pull down, abdominal exercises without weights), and leg exercises (e.g. leg press, seated two-leg hamstring curl).
Training was monitored daily one on one by personal trainers to ensure proper technique, said a McMaster University release.
'Our data show that simple things like regular weightlifting exercise and milk consumption work to substantially improve women's body composition and health.'
Phillips' lab is now following this study up with a large clinical weight loss trial in women.
The study will appear in the June issue of Medicine and Science in Sport and Exercise.
Smoke Alarm For Women
Around 50 per cent of women in the city smoked either due to work pressure or to suppress hunger, revealed the findings of two surveys conducted ahead of 'World No Tobacco Day', which is observed on May 31.
The two separate surveys were conducted by Dr Gauravi Mishra, consultant, Department of Preventive Oncology at Tata Memorial Hospital, and Dr Ravikant Singh, founder president of 'Doctor for You', a voluntary organisation, which works towards improving the lives of people through provision of better health and education.
Speaking at the conference here today, Dr Ravikant Singh said ''we found that 5 to 35 per cent of women in English media comprising entertainment channel, news channel and print, smoked 4 to 10 cigarettes per day, while few were chain smokers.
Around 15-20 per cent women, mostly staying alone in hostels or as PG or in live-in relationship, smoked to curb hunger for dieting, in such cases incident of Tuberculosis was reported among some women.
Dr Mishra said the growing phenomenon of smoking among women employees is due to peer pressure. Several BPO employees frequent hookah bars to unwind, while others smoke in either the office corridors or washroom, while a lot of women admitted to smoking, several other women were exposed to passive smoking.
Warning Bells For Beauty Contestants
A beauty queen contestant has come forward to warn other women of how her use of sunbeds for many years has left her battling skin cancer at the age of 24.

Miss York finalist Amy Hills, of Selby, North Yorks, would get an artificial tan at least once a week and she would also refuse to use suncream.

She discovered that all was not well during a visit to her doctor where she mentioned a mole on her arm had begun to change in appearance.

Tests were done and a few days later she was left horrified when it was confirmed it was cancerous.

Hills, who underwent surgery last week, was luckily the cancer had not spread but she will be needing constant checks.

"Like a lot of other young women, I wanted to look good and so would go for a tan about once a week. And when I sunbathed I wouldn't normally use suntan lotion," the Daily Star quoted her as saying.

"I thought it would never happen to me. But I noticed that the mole on my arm had begun to change about six months ago. When the test results came back saying it was cancer I was in a state of shock," she revealed.

Doctors have told her she needs a check every three months for the next five years.

"If I hadn't been to the doctor about something else, I might have left it for months more, which could have allowed it to spread further," she added.

Eat Fish For Healthy Children
Moms-to-be, please note--try to eat at least three portions of fish a week. Experts claim that it will reduce the risk of your children developing brain disorder.

A new research has found that omega3 fatty acids found in fish, known as docosahexaenoic acid, are essential for the brain to function properly.

According to the experts, the benefits of fish oil far outweighed other risks or concerns about the presence of potentially harmful contaminants in fish such as dioxins and methylmercury, which could harm a baby in the womb.

Professor Jack Winkler, the Director of Nutrition Policy Unit at London Metropolitan University said that there has been research which indicates that women who have eaten more fish than those recommendations suffer no harm but their child's brain performance improved.

Prof Michael Crawford, Director of the Institute of Brain Chemistry and Human Nutrition at London Metropolitan University said, unlike the rest of the body, the brain is mainly made of fat. It needs these fatty acids for brain growth and development.

Their research also suggested that docosahexaenoic acid deficiency may also play a role in the development of behavioural disorders such as ADHD in children.

The findings have been presented at a conference held at the Royal Society of Medicine in London.
