Women more nutritionally knowledgeable than men

Montreal: Women are, in general, more nutritionally knowledgeable and engage in healthier food shopping strategies than men, says a new research.
According to researchers from the University of Montreal in Canada, men's eating habits are associated with the availability of healthy food sources in their residential neighbourhood but women's are not.
"We found that for men only, intake of fruit and vegetables was positively associated with the proportion of healthy food outlets around home", said lead researcher Christelle M. Clary.
"Women rely on other aspects of the food environment than the proportion of food stores locally available," added professor Yan Kestens.
The study was based on data from the Canadian Community Health Survey (CCHS) and looked at the eating habits of 49,403 Canadians living in Toronto, Montreal, Vancouver, Calgary and Ottawa.

The food outlets of each city were mapped using a database containing information on the type and location of all food businesses.
For the purpose of this study, supermarkets, grocery stores, fruit and vegetable stores and natural food stores were considered as potential sources of "healthy foods" (especially fruits and vegetables), while convenience stores and fast-food restaurants were considered less healthy food sources.
"Overall, the data show that women from our sample declare eating on an average 4.4 portions of fruit and vegetables per day, almost one more daily portion than men," Clary said.
The research team believes that more research is needed to gain a better understanding of the mechanisms linking food environment and diet.

Holding breath beneficial for breast cancer patients

New York: New research shows that a breast cancer patient who holds her breath during radiation treatment can greatly reduce exposure to the heart.
Recent studies have shown that women with cancer in the left breast are at higher risk of heart disease. Such women present a particular challenge to radiation oncologists because it can be difficult to ensure that a sufficient dose of radiation is delivered to while adequately shielding the heart from exposure.
"We wanted to determine how effective breath-hold could be in shielding the heart from extraneous radiation exposure during treatment of the left breast," said first study author Harriet Eldredge-Hindy, researcher in the department of radiation oncology at Thomas Jefferson University.
The breath-holding technique allows doctors to monitor a patient's breath for the position that shifts the heart out of the range of the radiation beam.
In the largest prospective study to date, following women for eight years post treatment, 81 women were asked to hold their breath during radiation treatment for breast cancer.
