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.
