Low fat diet breast cancer hope

Following a low-fat diet may reduce the chance that breast cancer will return for some women, a study suggests.

The research found after five years, breast cancer had returned in 12.4 % of those on a standard diet - but in only 9.8% of those on a low-fat diet.

However, most women did not benefit, and experts say the findings may be due to other factors.

The Los Angeles Biomedical Research Institute study was presented to the American Society of Clinical Oncology.

Vitamin E cuts Parkinson's risk

A diet rich in vitamin E could protect against Parkinson's disease, believe researchers.

Good sources of vitamin E include green leafy vegetables, nuts and vegetable oils.

A study in Lancet Neurology pooled available data and found people who ate plenty of these foods in their diet were far less likely to develop Parkinson's.

The authors said it was impossible to tell if supplements would do the same.

Yeast intake linked to longevity

Restricting the amount of yeast in the diet can increase life expectancy by 50%, research into fruit flies has shown.

It is not yet clear whether the same might be true in humans.

But the authors say their findings hint it might be what you eat rather than total calorie intake that influences longevity, contrary to current belief.

The University College London team told PLoS Biology how it could be down to metabolic pathways triggered by foods.

Drinking milk 'no risk to heart'

Milk's poor reputation as being an unhealthy drink may be unjustified, research suggests.

Scientists found drinking milk does not increase the risk of heart disease and stroke - in fact it may even have a protective effect.

The study is published in the Journal of Epidemiology and Community Health.

Natural relaxant may help asthma

Scientists say a substance which acts naturally to open airways could be used to protect against asthma.

Duke University Medical Center researchers found mice with asthma had too little of the chemical, which relaxes airways so people can breathe.

Asthma research has previously tended to focus on what might cause airways to become constricted.

The researchers, writing in Science, said their findings could lead to new ways of treating the condition. The natural compound, called nitrosoglutathione (GSNO), a molecule in the nitric oxide (NO) family, which keeps airways open.

Vitamin C could counteract some of the harmful effects that smoking during pregnancy can have on unborn babies, scientists say.

High doses of the vitamin protected against nicotine-associated damage in monkeys, the Oregon Health & Science University team found.

Fake acupuncture 'aids migraines'

Fake acupuncture works just as well as the real thing in relieving migraines, scientists have found.

In a study of more than 300 patients, both genuine and sham acupuncture reduced the intensity of headache compared with no treatment at all.

But real acupuncture was no better than needles placed at non-acupuncture points on the body, the Journal of the American Medical Association reports.

It goes against recent research showing acupuncture works in its own right.

Exercise 'slows prostate cancer'

Regular vigorous physical activity could slow the progression of prostate cancer in older men, a study has found.
