One of the cancers that may
be most easily prevented with diet and lifestyle changes is colorectal cancer—cancer
of the large intestine and rectum.
This is the fifth most common
type of cancer and the third leading cause of death in the United States.
When you consider the number
of people who are constipated, and the Frankenstein foods that people eat, this
may not be so surprising.
Cancer is a systemic disease,
which means that the whole system is over-burdened and toxic to the point that
rogue cells take hold and develop their own “entity” within the body. Your food
and your blood are hijacked to feed the new entity or tumor. Of course, the
host eventually dies, and so does the new colony. It is one of the oddities of nature,
considering that survival is the usual operating modality.
Unburdening your toxic load
is one of your best defenses against this, and any other type of cancer.
Studies indicate that eliminating highly processed meats, refined sugars and
refined (white) grains such as wheat, white rice, and soy may lower risk.
Maintaining a healthy weight is a factor, and eliminating refined starches and
sugars would help with weight control.
In recent years red meat has
been considered a risk factor, but a review of the history of human health and
nutrition did not correlate, since humans have eaten higher meat diets in the
past, with little historical evidence of cancer. Studies show that it is the
preparation of meat that is a factor. Meat that is heavily browned on the
surface and over-cooked increases risk. When meat is over-cooked the proteins
and amino acids are broken down and can no longer be utilized in the body for
repair and nutrition.
High protein intake overall
was not associated with risk, but even seemed protective in some studies.
Consumption of fish and poultry as alternatives to red meat showed some
protection. Fish Oil supplementation seemed to decrease risk in women, but also
decreased inflammation in both sexes, and therefore may be generally helpful.
Intake of fiber from fresh
vegetables and whole fruits appear to be protective of other gastrointestinal
issues such as constipation and diverticulitis. However, the high fiber
supplementation theory for cancer protection has not borne out. Diets high in
fruits and vegetables were associated with slightly lowered risk of colorectal
cancer. Since certain vegetables, such as cabbage, broccoli, kale and brussel
sprouts have sulfur compounds, which are necessary for PhaseII liver
detoxification, these vegetables may have potential in cancer prevention for
all types of cancer.
Inflammation appears to be an
issue and intake of B vitamins that decrease inflammation, such as folate, are
associated with lower risk. Naturally occurring folate is not the same as
synthetic folic acid, and folate is what was found to lower cancer risk. Eggs
are a good source, as well as dark green veggies such as kale, spinach and
broccoli. Look for unfortified Brewer’s Yeast too. Brewers Yeast is also a good
source of selenium, which was associated with a 50% reduction in colon cancer
in one study.
Note that red meat contains B
vitamins, and particularly the organ meat of the animal. The fact that we no
longer consume the most nutritious parts of the animal may be one reason we see
more colon cancer now than we did in past times when people did not waste any
part of the animal. Organ meat was even considered a delicacy!
Alcohol is a risk, but the
amount is not determined. High consumption definitely raises one’s risk, and
alcohol metabolism will burn folate and other B vitamins. Whether two or less
drinks per day are a risk is undetermined.
Evidence suggests that a high
level of physical activity lowers risk, even when weight is not managed in
normal ranges.
So, we can conclude that
lifestyle and dietary changes can lower the risk of developing colon and rectal
cancer, and may lower it significantly. Basic and common sense changes towards
organic whole foods bring about generally improved health and vitality. The
same smart choices are the key to colon health.
If your colon is not
functioning well, see your health practitioner. A colonoscopy may check for
risks, but it is not enough to prevent problems that could develop into cancer.
