Weight gain linked to risk of aggressive cancer - study

The usual rubbish. They are most likely just picking up that poor people tend both to get fatter and to have poorer heath generally anyhow. Note that it is the moderately overweight who have the longest lifespans

THE risk of death from prostate cancer nearly doubles in men who have put on 20 kilograms or more in their adult life, new Australian research has found.

The paper, published in the International Journal of Cancer, shows an increase in body weight during a man's adult life is associated with an increased risk of suffering an aggressive form of prostate cancer and of dying from prostate cancer.

Having a high body mass throughout life was also associated with increased risk of aggressive prostate cancer. "This study and other similar studies have shown that obesity is related to aggressive and fatal cancer," said the study's co-author, Dallas English. "Maintaining a healthy weight during adult life is really the bottom line."

Professor English, director of the centre for molecular, environmental, genetic and analytic epidemiology at the University of Melbourne, said one of his concerns was that the study - of more than 17,000 Australian men aged 40 to 69 - drew participants from a generation in which childhood obesity was not a significant issue.

He said the higher rates of obesity among children now might worsen outcomes. "In Australia, things have changed a lot," he said. "We haven't had the experience of people growing up with childhood obesity."


Daily dose of rosehip extract could help cut heart disease by lowering blood pressure and cholesterol levels

The small changes observed may have no clinical significance. Journal article here

A daily dose of the herbal remedy rose hip could cut the risk of heart disease, new research shows. Obese patients who consumed a drink made with rose hip powder every day for just six weeks saw their blood pressure and cholesterol levels drop significantly.

The tiny berries, which sprout at the end of the rose-blooming season, have been used for centuries as a folk remedy for conditions like arthritis. They are packed with vitamin C and are thought to have powerful anti-inflammatory properties.

One study in 2007 showed patients with sore joints who took a rose hip capsule every day experienced a 40 per cent drop in pain levels and a 25 per cent improvement in mobility.

In the latest research, published in the European Journal of Clinical Nutrition, scientists at Lund University in Sweden recruited 31 obese men and women to see if a daily concoction made with rose hip powder would reduce their risks of developing type two diabetes and heart disease.

Each one spent six weeks drinking the rose hip solution, made with 40 grammes of rose hip powder, followed by six weeks on a drink make from apples and grapes.

At the end of each experiment, researchers measured patients’ body weight, blood pressure, blood fat levels and glucose tolerance - a test to see if they are in the early stages of diabetes.

After six weeks on the rose hip drink, patients saw their blood pressure drop an average of 3.4 per cent, a small but significant decline, and their total cholesterol levels drop by almost five per cent.

Further tests revealed a bigger drop - six per cent - in levels of LDL cholesterol, the ‘bad’ type of blood fat thought to heighten heart disease risks.

Scientists estimated that the drop in cholesterol and blood pressure combined would reduce the risk of heart disease in obese patients by 17 per cent.

And they said if further studies confirmed the cardiovascular benefits of the common garden berry, it could even be used as an alternative therapy for patients who are unable to take the anti-cholesterol drugs statins due to side effects.

In a report on their findings the researchers said: ‘The findings may have important health implications. They may represent an attractive alternative to statin treatment for people that, because of muscle pain and increases in liver and muscle enzymes, do not tolerate statins.

‘The same is true for people at risk of developing diabetes, as statins recently were shown to increase the risk of diabetes.’
