A new study published in the journal Cancer Epidemiology, Mile Markers, and
Prevention is presenting evidence of the link between the consumption of
refined carbohydrates and cancer. This case-controlled study looked at the
dietary habits of over 1,800 women in Mexico, and found that those who got
57% or more of their total energy intake from carbohydrates showed a 220%
higher risk of breast cancer than women with more balanced diets.

This study shows that foods with high glycemic index values -- that is,
foods
that more quickly raise blood sugar levels in the human body -- actually
accelerate the growth of cancer cells and tumors in the human body.
Researchers involved with the study propose that the correlation between the
consumption of refined carbohydrates and breast cancer could be related to
elevated levels of insulin and the fact that many breast cancer tumors are
encouraged and supported by high levels of insulin in the body.

To anyone who has read some of the books about sugar, refined
carbohydrates, low carb dieting, or even my own book, called Low carb Diet
Warning, none of this should be a surprise. We in the holistic nutrition
world
have long known that the consumption of processed carbohydrates actually
causes cancer, and not just breast cancer, either. It actually promotes many
forms of cancer, including colon cancer. Thankfully, new scientific evidence
is
now appearing that supports these notions.

But many people in the general public still do not know that consuming
refined carbohydrates causes cancer, and thus they continue to drink soft
drinks containing high-fructose corn syrup, they continue to eat breakfast
cereals loaded with sugars and corn syrup, and they continue to eat large
amounts of white flour in products like pancakes, breads, pastries, cookies,
and crackers, oblivious to the idea that they are actually giving themselves
cancer.

Once again, we see that preventing cancer comes down to dietary choice.
One of the easiest things a person can do to prevent cancer, based on this
research, is to avoid all processed carbohydrates. That means eliminating
from your diet refined white flour, refined white sugar, milled grains, and
ingredients like high-fructose corn syrup. These ingredients are all
man-made
or artificially processed ingredients that are not normally found in nature.
You
don't find refined white sugar growing in the sugar cane fields. You don't
see
white flour growing on wheat grass stalks in the field. Instead, you see
whole
grains growing in nature, and it is these whole grains that should be
consumed by human beings if they wish to attain a high degree of health.

This research also indicates why low carb dieters and people following the
Atkins diet may be doing themselves a huge favor in terms of disease
prevention. Avoiding processed carbohydrates reduces your risk of being
diagnosed with cancer. Unfortunately, many low carb dieters, as you may
know, end up consuming other cancer-causing ingredients that are present in
many low carb foods. Those ingredients can include sodium nitrite,
monosodium glutamate, and artificial chemical sweeteners such as
aspartame, also known as NutraSweet.

So, the real story here is to avoid processed carbohydrates as much as you
can. At the same time, avoid chemical additives that are found in processed
foods, especially artificial sweeteners and chemical taste enhancers. The
foods that you should be consuming to support outstanding human health are
the same ones we've been talking about here for years, and those are natural
foods found in nature, such as whole grains, nuts, seeds, vegetables,
fruits,
and healthy oils.

Overview:

In a case-control study of 1,866 women in Mexico, those who derived 57 or
more percent of their total energy intake from carbohydrates incurred a risk
of
breast cancer 2.2 times higher than women with more balanced diets.
The team of researchers from the Instituto de Salud P?blica in Cuernavaca,
Mexico, and the Harvard School of Public Health in Boston, suggests that the
association between carbohydrates and breast cancer may be related to
elevated levels of insulin and insulin-like growth factor binding proteins
in the
blood.
"Now, with studies like ours, we are beginning gradually to understand what
elements of diet specifically are associated with the disease, and to grasp
the chemical and biological processes that contribute to it at the cellular
level."
Of all the carbohydrate compounds, sucrose and fructose demonstrated the
strongest association with breast cancer risk in the study.
Sucrose is derived from sugar cane, sorghum and the sugar beet; it is most
commonly found in table sugar and sweetened prepared foods and
beverages.
Dietary fat -- certainly a contributor to obesity -- fared well in the
research,
showing no significant association with breast cancer risk overall.
Willett noted, however, that the intake of polyunsaturated fat by the women
in
the study group was only about half that of the United States population.
Founded in 1907, the American Association for Cancer Research (AACR) is a
professional society of more than 22,000 laboratory and clinical scientists
engaged in basic, translational, and clinical cancer research in the United
States and over 60 other countries.
