Insomnia linked to higher mortality risk in men
Researchers
have found that some insomnia symptoms, the most common sleep disorder, are associated with an
increased risk of mortality in men.
The study's lead author Yanping Li from Brigham and Women's Hospital (BWH) said that their research also showed that among menwho experience specific symptoms of insomnia, there is a modest increase risk in death from cardiovascular-related issues.
Specifically, researchers report that difficulty falling sleep and non-restorative sleep were both associated with a higher risk of mortality, particularly mortality related to cardiovascular disease.
Researchers followed more than 23,000 men in the Health Professionals Follow-Up Study who self-reported insomnia symptoms for a period of six years.
After adjusting for lifestyle factors, age and other chronic conditions, researchers found that men who reported difficulty initiating sleep and non-restorative sleep had a 55 per cent and 32 per cent increased risk of CVD-related mortality over the six year follow up, respectively, when compared to men who did not report these insomnia-related symptoms.

Vegetable oils increase heart disease risk
A new study has revealed that some vegetable oils that
claim to be healthy may actually increase the risks of heart disease.
Replacing
saturated animal fats with polyunsaturated vegetable oils has become common
practice because they can reduce serum cholesterol levels and help prevent
heart disease.
"Careful evaluation of recent evidence, however, suggests that allowing a health claim for vegetable oils rich in omega-6 linoleic acid but relatively poor in omega-3 alpha-linolenic acid may not be warranted," Drs. Richard Bazinet, Department of Nutritional Sciences, University of Toronto and Michael Chu, Lawson Health Research Institute and Division of Cardiac Surgery, Western University, London, Ontario said.

Corn and
safflower oil, which are rich in omega-6 linoleic acid but contain almost no
omega-3 alpha-linolenic acid, are not associated with beneficial effects on heart health according to recent evidence.
In the study the intervention group replaced saturated fat with sources of safflower oil or safflower oil margarine (rich in omega-6 linoleic acid but low in omega-3 a-linoleic acid).
They found that the intervention group had serum cholesterol levels that were significantly decreased (by about 8percent-13percent) relative to baseline and the control group, which is consistent with the health claim.

However, rates
of death from all causes of cardiovascular disease and coronary artery diseasesignificantly
increased in the treatment group.

published in the Canadian Medical Association Journal.
