Ten Studies Showing the Link Between Sugar and Increased Cancer Risk
by Reuben Chow
(NaturalNews) How many times have you heard it mentioned that sugar
causes cancer, that cancer patients should avoid sugar, or that sugar
is the favorite food of cancer cells? The truth is, this goes beyond
mere hearsay or traditional knowledge; there is actually a large
volume of scientific evidence available which shows the link between
sugar and increased cancer risk. Here, ten such studies are
summarized.
1. Colorectal Cancer in Women (United States)
A study conducted by Harvard Medical School found that women who ate
the most foods with high glycemic load – the glycemic index, or GI, of
a food gives an idea of how quickly sugar (more specifically, glucose)
levels in the blood rise after eating it – had almost three times the
risk of getting colorectal cancer in the future, compared with women
who ate lesser amounts of such foods.
Typically, processed foods made from refined grains and refined sugar,
including candy bars, cakes, cookies and other snacks, are high
glycemic foods
“We find a very straightforward and clear association between high-
glycemic foods and the risk of colorectal cancers,” said lead
researcher Simin Liu, MD, ScD.
This study involved some 40,000 American women.
2. Colorectal Cancer in Men (United States)
Another study at Harvard University found that middled aged men whose
diets tended to increase blood sugar levels quicker, i.e. those who
ate more high GI foods, had a 32% higher chance of getting colorectal
cancer over a period of 20 years.
The study, which involved more than 50,000 men, also found that this
effect seemed to be more pronounced in heavier men.
3. Breast Cancer in Women (United States)
The Women’s Health Study found that those who consumed a diet which
raised blood sugar levels more had a 135% higher risk of getting
breast cancer in the 7-year period of the study.
4. Endometrial Cancer in Women (United States)
The Iowa Women’s Health Study looked at some 23,000 post-menopausal
women. It found that those who consumed a diet which raised blood
sugar levels more had a 46% higher risk of getting endometrial cancer
over a period of 15 years.
5. Endometrial Cancer in Women (Italy)
Another study in Italy carried out on women with endometrial cancer
found that those who consumed a blood sugar-raising diet had a 110%
higher risk of getting this disease.
6. Pancreatic Cancer in Women (United States)
In a study which followed almost 90,000 US women participating in the
Nurse’s Health Study for a period of 18 years, it was found that women
with a high glycemic load intake had a 53% higher risk of getting
pancreatic cancer. A similar increase in risk, 57%, was observed for
fructose intake.
Further, the study also found that women who were heavy and with low
levels of physical activity experienced greatly enhanced risk. Women
in this group with high glycemic load had 2.67 times the risk of their
counterparts with low glycemic load intake!
7. Pancreatic Cancer in Men and Women (Sweden)
A study carried out by Karolinska Institute in Stockholm, Sweden and
Central Hospital in Västerås, Sweden followed almost 78,000 Swedish
men and women with no previous diagnosis of cancer or history of
diabetes for a mean period of more than 7 years. The subjects were
aged from 45 to 83 years.
The study found that consuming added sugar, soft drinks, sweetened
fruit soups or stewed fruit increased the risk of pancreatic cancer.
Those who ate the most sugar had a 69% higher risk compared with those
who ate the least sugar. The corresponding higher risk for soft drinks
was 93%, while for sweetened fruit soups or stewed fruit it was 51%.
The study concluded that “high consumption of sugar and high-sugar
foods may be associated with a greater risk of pancreatic cancer”.
8. Prostate Cancer in Men (Italy)
An Italian study examined the habits of men aged 46 to 74 who had
prostate cancer and compared their dietary choices to similar men who
did not contract the disease. The study found that those men whose
diets were more likely to increase blood sugar levels had a 57% higher
risk of getting prostate cancer.
9. All Cancers in Men and Women (Korea)
A large study carried out by Johns Hopkins Bloomberg School of Public
Health and Yonsei University in Seoul, Korea tracked almost 1.3
million Korean men and women, aged between 30 and 95 years, for a
period of 10 years.
The study found that those with the highest fasting glucose levels
were more likely to die from all types of cancer combined. For the
men, the strongest link was found for pancreatic cancer, while
significant links were also reported for oesophagus, liver and
colorectal cancers. For the women, the strongest associations were for
liver and cervical cancers.
All in all, besides being more likely to die from cancer, those with
highest fasting blood glucose levels also had higher risk of
developing cancer.
And obesity had a part to play, too. “This study provides more
information on glucose intolerance, an emerging cause of cancer. It
points to increased cancer risk as another adverse consequence of
rising obesity around the world,” concluded Sun Ha Jee, leader of the
study.
Another thing to note - the study participants were said to be
substantially leaner than the typical population in Western countries,
as mentioned by the study team.
10. Various Cancers in Men and Women (Sweden)
A study carried out at Umea University Hospital in Sweden looked at
almost 65,000 people in northern Sweden for a mean period of 8 years.
The study found that women with the highest blood sugar levels had a
higher risk of getting cancer before the end of the study period. This
group of women also had higher risk of endometrial cancer, while those
below 49 years of age had higher risk of breast cancer. In addition,
both men and women who had the highest levels of blood sugar had
higher risks of pancreatic cancer, urinary tract cancer, as well as
malignant melanoma.
These results led Par Stattin, MD, PhD, part of the study team, to
state that keeping blood sugar levels within the normal range "may
reduce cancer risk".
Why Does Cancer Love Sugar? – A Study Suggests Why
A study team at Duke University School of Medicine has suggested a
possible reason why cancer cells like sugar so much.
Basically, according to the researchers, in healthy cells, certain
growth factors regulate their metabolism and cell survival. When these
growth factors are removed, there is loss of glucose uptake and
metabolism, and the cells die.
However, they found that cancer cells are able to maintain glucose
metabolism by using a protein called “Akt”, which promotes glucose
metabolism. This prevents cell death, even when the growth factors are
not available.
What We Need to Take Note of
So, then, based on the findings of the abovementioned studies, can we
conclude that sugar feeds cancer? The truth is, sugar feeds all cells
in our bodies. It therefore cannot be all bad.
Two things we must take note of, however, is the amount and the type
of sugar which we consume.
Consuming too much sugar causes our bodies to produce excessive
amounts of insulin. And insulin itself encourages the growth of cells,
something which is good for healthy cells, but not cancerous cells.
The other key point is to avoid simple sugars. Broadly speaking,
processed and refined foods, including soft drinks, sugary beverages,
candy bars, cakes, other desserts, as well as other snacks, contain
high amounts of simple sugars. These are high GI foods, which can
cause insulin levels to spike.
On the other hand, natural sugars found in fruits and vegetables are
so much safer and better for health. Even fresh fruit juice, despite
its high sugar content, is great for health. On top of that, healthy
whole foods come with a wide concoction of vitamins and minerals,
something which refined sugar is totally devoid of.
Simple Sugars Cause Obesity
When one’ insulin levels suddenly increase, the level of sugar in the
blood can suddenly crash. This, then, can cause one to feel intensely
hungry. People then eat more, and feel hungry again soon, and the
cycle keeps going.
Further, because of their lack of nutrition, foods with a lot of
simple sugars are basically empty calories. When the body’s
nutritional needs are not met, it continues to crave for food, which
again explains the non-stop eating and feasting.
The more refined sugars one eats, the fatter one becomes, yet the more
malnourished one can be. It is a huge paradox, and a dangerous one at
that.
Conclusion
Refined sugar is devoid of important nutrients, causes obesity, causes
cavities, and also increases cancer risk. If you or a loved one are
battling cancer, or are serious about avoiding the disease, you may
want to take note of your intake of this common yet dangerous
substance.

Just an aspect of this makes the point. Simple carbohydrate
diets raises blood lipid levels, lead to obesity, and
the obesity drops the vitamin D levels even in persons
get quite a bit of the vitamin. Also there is an issue whether it
healthier to be burning mainly fats as opposed
to sugar when faced with cancer and which
diet best leans toward apoptosis of cancer.
I will say I don>t have a bright line between
the natural and the artifical. Indeed, some
look to hard for the line only to the
