that higher levels of egg consumption during adolescence are associated
with a decreased risk of breast cancer.
dietary fiber and vegetable fat was also attributed to a reduced
risk of developing the disease -- butter appeared to increase the
more scientists study the links between diet and breast cancer risk,
the more facts get sifted out.
example, some immigrant populations in the United States have lower
rates of breast cancer than the general population. But second generation
Americans usually have the same risk as the general population.
observations suggest that exposure to certain foods during childhood
and adolescence may be critical in establishing a womans risk
of developing breast cancer.
Frazier and colleagues from Harvard Medical School and the Harvard

that may affect the risk of developing breast cancer, such as family
history, diagnosis of benign breast disease, and use of hormone
results of the survey revealed that eating more eggs, vegetable
fat and dietary fiber between the ages of 1218 may decrease
the risk for breast cancer, and high consumption of butter appeared
to increase the risk.
researchers suggest that eggs may protect because of their high
levels of essential amino acids, vitamins and minerals, and dietary
fiber may have a similar effect through its ability to bind estrogen
within the digestive system.

of the breast and, yet, has also been associated with increasing
a womans risk for breast cancer.
is less clear why butter appears to have such a radically different
effect from vegetable oils. The authors believe that more information
on the composition of vegetable oils will be needed before an explanation
can be given.
stress that their work represents a preliminary study and that future
studies are needed to establish a clearer picture of the links between
diet and breast cancer.
