Can diet influence the risk of getting breast cancer?
Posted by admin on Thursday, October 16th, 2008
More and more studies showing now that the type of foods we
eat can genetically modify our bodies and the risk of all
major diseases.
For years, researchers have studied the role of diet
in breast cancer. By comparing different countries,
researchers found strong links between high fat diets and
breast cancer risk. The disease is rare where the diets are
very low in fat and where rice and other plant products are
dietary staples. For example, before 1950, the rice-based
Japanese diet drew less than 10 percent of its calories from
fat. Breast cancer was exceedingly rare. But over the years,
as Western influences have altered Japanese eating habits,
breast cancer rates have climbed dramatically.
These international studies are just one line of
evidence, however. Case-control studies are another research
tool in which researchers compare diets of cancer patients (
“case”) with those of healthy women of similar age and
background ( “ control”). Such studies have also shown a
links between fatty diets and higher risk of breast cancer,
and even on cancer patient’s chances for survival. One
study tracking Canadian breast cancer patients for ten years
found that for 5 percent increase in saturated fat in diets,
the risk of dying of breast cancer shot up by 50 percent.
How does fat do its dirty work? Fat increase the
amount of estrogen in the blood. In turn, this hormone
stimulates breast cells in such a way that cancer is more
likely to occur and is more aggressive. Fatty foods also
leads to obesity which itself is linked to higher estrogen
levels in the blood. Increased estrogen levels are also
linked with early menarche ( onset of first period), also a
breast cancer risk factor.
Despite such evidence, doubts about the fat
connection have persisted, fueled mainly by the results of a
large study of nurses run by Harvard University in which
researchers found no association between fatty diets and
breast cancer rates.
Why the conflicting results? Unlike the
populations examined in international studies, the nurse
were a fairly homogeneous group, all eating fairly high-fats
diets. No group in the study was following anything similar
to a traditional Asian diet or other low -fat diet.
As important as it is to get fat off your plate,
it’s just as important to pile on the vegetables and other
healthful plants foods. Their fiber helps cut breast cancer
risk by naturally decreasing estrogen levels. Plants foods
are also rich in beta-carotene, vitamin C, and other
vitamins which protect cells against damage. Unlike animal
products, most plants foods have little fat and do not store
up large amounts of pesticide residue.
A brisk morning walk- or any other regular exercise-
also helps cut breast cancer risk.
Of course, the good fats ( omega 3 and 6), known as
essential fatty acids are vital to one’s health. Their
paramount importance comes from the facts that they
constitute the membranes of every cell in the body,
therefore the ones allowing nutrients into the cells(to be
processed) and toxins out of the cells ( to the eliminated).
The major organ helping fats metabolism is the liver,
therefore ensuring that the liver always works well one can
reduce breast cancer risks.
