Who isn’t afraid of the word
“cancer”? We all know a family member or a friend who had it. And indeed,
according to the American Cancer Society, more than one million people in the
United States get cancer each year. The American Cancer Society lists many
possible causes to cancer disease, including genetic factors, lifestyle factors
such as tobacco use, diet, and physical activity, certain types of infections
and environmental exposures to different types of chemicals and radiation.
Since I’m very interested in healthy nutrition, and foods that are protect
against cancer development, but it won’t help if we eat those foods while
consuming large amounts of other foods that can increase the risk of cancer. So
let’s have a look at these cancer promoting foods so we all know not only what
to eat, but what NOT to eat (or at least reduce their intake).
1. High intake of processed foods
Many diverse substances are
adjoined to commercially prepared foods, such as artificial colors, chemical flavors,
salt, sugar or artificial sweeteners. These additives are frequently
investigated by researchers to check if any of them is thought to be a real
risk. Sometimes there is a scare about a particular additive and some additives
are thought to be a cancer risk. Heavily salted, smoked and pickled foods, for
example, may increase the risk of stomach cancer. This may well explain why
there is high rate of stomach cancer in Japan, because salty and pickled foods
are very popular. Also an epidemiological study published in June 2010 in the
American Journal of Clinical Nutrition observed that a high salt food can
increase in 10% risk of stomach cancer. Furthermore artificial food coloring
are noticed numerous health risks and research has been is limited to animal
studies, including mice and rats, but some claim that these dyes are possibly
toxic enough to cause the cancer in the humans.
2. High intakes of red meat,
processed meat or charred food
It has been observed the peoples
who eat lots of red processed meat can cause bowel and stomach cancer. Red meat
includes all fresh, minced and frozen beef, pork, lamb or veal, particularly
pork is so injurious for health and leads to cancer. Therefore processed meats possess a risk of
cancer, and these have been preserved in some way other than freezing and
include bacon, ham, salami, sausages, corned beef, black pudding, pâté and
tinned meat. When you eat processed meats, you are exactly assure consuming
sodium nitrite or sodium nitrate, which are added to processed and cured meats
to preserve color and extend shelf life. Unluckily, these compounds can be
converted to nitrosamine, which is very much famous to cause cancer in
laboratory rats (though again, the connection in people is unclear). Also hot
dogs, bacon and the like may also be preserved by methods involving smoke or
salt, which also increases the exposure to potentially carcinogenic chemicals.
Charred food creates chemicals which can damage human cells, and making them
more likely to become cancerous. However; it is highly depend on the way you
cook your meat can potentially make a big difference in the cancer risk it
poses to you. The char-grilled meats that are somewhat burnt on the outside are
among the worst foods that increase the risk for cancer.
3. Sugar
There are a number of websites
that encourage the idea of sugar “feeds” cancer. They suggest that eating foods
with sugar makes cancer breed faster. Due to this some cancer patients avoid
eating any sugar, and rejecting beneficial foods, i.e. fruits, that contains
vital nutrients. Therefore no decisive research on human subjects to verify
that sugar makes cancerous cells grow. Avoiding foods with processed sugar is a
decent idea in general, but disregarding foods with natural sugar won’t stop
cancer cells from dividing. As per Mayo clinic, sugar doesn’t make cancer grow
faster. All cells (including cancer cells) depend on blood sugar (glucose) for
instant energy. But giving extra sugar to cancer cells doesn’t speed their
growth. Similarly, depriving cancer cells of sugar doesn’t slow their growth.
According to Canadian Cancer Society the connection between sugar and cancer is
different, eating abundance of sugary foods can cause of rapid gaining weight.
Research shows that obese habit or being overweight can increase risk of
cancer. Normally obesity may cause changes in hormone levels or insulin that
might increase the risk of developing breast, colon or uterine cancer. Thus
limiting the sugar level in your diet is really important. High sugar in your diets
sugar and refined carbohydrates can lead to overweight and obesity, which
indirectly increases cancer risk over time. Sugar can be found several foods
such as cookies, sodas, cakes, soft drinks and other sweets even in pasta
sauce, salad dressing and canned vegetables. So you’ve to read out food labels
carefully, look for sugar e first ingredient and be aware of hidden sugar
names: fructose, lactose, sucrose, maltose, glucose, dextrose. Natural sugars
such as molasses, honey and maple syrup contain beneficial antioxidants but
those, too, should be consumed in moderation. If you tend to have sugar
cravings, you may want to read my article 13 effective ways to quit sugar.
4. Fried food, French fries, potato chips and
snack food
It is highly important that
French fries, potato chips and other snacks you eat, actually may have high
levels of acrylamide, another carcinogenic substance that forms when foods are
heated at high temperatures, such as during baking or frying. Acrylamide may be
gotten in any food heated to a temperature above 250° F, but potato chips &
French fries have been observed highest levels of among foods tested. Therefore
cooking methods i.e. frying, baking or roasting are more likely to produce
acrylamide, whereas boiling, steaming, and microwaving appear less likely to do
so. Longer cooking times and cooking at higher temperatures can raise the
amount of acrylamide in foods further. It is most important to mentioned here,
that the prolonged exposure to acrylamide has caused a range of tumors in
animal tests (rats and mice), whereas most of the human studies published so
far have failed to find any connection between acrylamide and several types of
cancers. Therefore many believe it has a potential to be a human carcinogen
because of those animal studies. If you are still worried, the FDA and other
public health groups suggest the best way is to follow the general advice on
healthy eating, including limiting the consumption of fried and fatty foods. Another
component found in these types of foods that may increase the risk for cancers
are Trans fats or trans fatty acids. These are formed when manufacturers turn
liquid oils into solid fats via a process called hydrogenation. And indeed, Tran’s fats can be found in many
foods including vegetable shortening, margarine, crackers, cereals, candies,
baked goods, cookies, granola bars, chips, snack foods, salad dressings, fried
foods, fats and many other processed foods. Tran’s fats cannot only increase
your risk of cardiovascular disease and two types of diabetes, but the high
intake of trans-fatty acids may have a direct association with prostate cancer
in men, which ranks number one among the most common malignant cancers in
American men. Chronic inflammation plays an important role to the development
of prostate cancer and the association of trans-fats and chronic inflammation
may explain the link between prostate cancer and trans-fatty acid ingestion.
However, further studies and clinical trials are needed to establish this fact.
5. Excess alcohol
Scientific and researchers have
strong consensus of the linking between alcohols drinking causing several types
of cancer. The peoples who drink alcohol regularly could be high risk of
developing an alcohol-related cancer. According to Cancer Research UK and
American Cancer society, alcohol can increase the risk of cancers, like as
mouth cancer, liver cancer, breast cancer, bowel cancer and throat cancer.
You have perhaps heard about other studies
that have found that certain substances in red wine, such as resveratrol, have
anti-cancer properties, but like several things in life moderation is the key.
The nutrition guidelines suggest physical activity plays a key role for cancer
prevention; the people, who drink alcohol, have high risk of cancer.
