Hirayama notes that in Japan death rates for stomach cancer have been declining. The study investigated the connection between the decreased death rates and stomach cancer.

Over an 18 year period male stomach cancer death rate have fallen by:
25%  in the age group 40 to 44
34% in the age group 45 to 49,
35% in the age group 50 t0 54
30% in the age group 55 to 59
30% in the age group 60 to 64
19% in the age group 65 to 69

Over the same period female death rates have also fallen. Their rates are:
25%  in the age group 40 to 44
22% in the age group 45 to 49,
30% in the age group 50 t0 54
31% in the age group 55 to 59
28% in the age group 60 to 64
30% in the age group 65 to 69

Hiramaya found the following changes in food consumption:
(a) Carbohydrate consumption decreased by 14%.
(b) Rice consumption decreased by 19%.
(c) Potato consumption decreased by 56%.
(d) Fat consumption increased by 126%.
(e) Egg consumption increased by 1191%
(f) Meat consumption increased by 1269%.

This study found that as carbohydrate consumption declined and meat and fat consumption increased the rates of stomach cancer decreased.

This study examined the connection between various types of food and stomach cancer. Included in the study were 1,124 stomach cancer patients (age 20-69) and 1,451 controls without stomach cancer.

The study found with regard to carbohydrate type food:

• Men with the highest carbohydrate consumption had a 50% increased risk of stomach cancer compared to men with the lowest carbohydrate consumption.
• Women with the highest carbohydrate consumption had a 90% increased risk of stomach cancer compared to women with the lowest carbohydrate consumption.
• Men eating the most noodles and bread had a 10% increase in stomach cancer risk compared to men who ate the least noodles and bread.
• Women eating the most noodles and bread had a 20% increase in stomach cancer risk compared to women who ate the least noodles and bread.

The study found with regard to meat and fat:

• Men eating the most fresh red meat had a 10% decreased risk of stomach cancer compared to men eating the least fresh red meat.
• Women eating the most fresh red meat had a 20% decreased risk of stomach cancer compared to women eating the least fresh red meat.
• Men consuming the most eggs had a 40% reduction in stomach cancer risk compared to the men eating the least eggs.
• Women consuming the most eggs had a 50% reduction in stomach cancer risk compared to the women eating the least eggs.
• Men with the highest fat consumption had 30% less incidence of stomach cancer compared to men with the lowest consumption of fat.
• Women with the highest fat consumption had 40% less incidence of stomach cancer compared to women with the lowest consumption of fat.

This study shows that a high carbohydrate diet increases the risk of stomach cancer whereas a diet high in fat, red meat and eggs lowers the risk of stomach cancer.

The associations of dietary carbohydrates, dietary glycemic load, and dietary fiber with endometrial cancer risk were analyzed among 288,428 women over a 6.4 year period with a total of 1,842, 995 person years of follow up.

The study found:

• For every 100 grams per day rise in carbohydrate consumption there is a 61% increased risk of endometrial cancer.
• For every 50 units per day rise in glycemic load there is a 40% increased risk of endometrial cancer.
• For every 10 gram per day rise in fibre consumption there is a 27% increased risk of endometrial cancer.

This study shows that a higher carbohydrate and fibre consumption is linked to an increase in endometrial cancer.

The objective of the study was to evaluate the association of carbohydrates and dietary fibre with breast cancer risk. A total of 74,942 women aged 40-70 were involved in the study which lasted over 7 years.

The study found:

• Women who ate the most carbohydrate had a 22% increased rate of breast cancer compared to the women who ate the least carbohydrate.
• Women who ate the most fibre had a 9% increased rate  of breast cancer compared to the women who ate the least fibre.

This study found that increased dietary carbohydrate and fibre leads to higher rates of breast cancer.

This study investigated the relationship between diet and pancreatic cancer in 436 patients and 2003 general-population control subjects aged 30-79 years.

The study found:

• Those who had the lowest consumption of bread, grains and cereals had an 8% decreased rate of pancreatic cancer compared to those who had the highest consumption of bread, grains and cereals.
• Those who had the lowest consumption of carbohydrates had a 36% decreased rate of pancreatic cancer compared to those who had the highest consumption of carbohydrates.
• Those who ate the most fat had a 34% decreased rate of pancreatic cancer compared to those who ate the least fat.
• Those who ate the most saturated fat had a 28% decreased rate of pancreatic cancer compared to those who ate the least saturated fat.
• Those who ate the most red meat had an 18% decreased rate of pancreatic cancer compared to those who ate the least red meat.

This study shows that diets high in saturated fat and red meat offer protection from pancreatic cancer.

Is there a role for carbohydrate restriction in the treatment and prevention of cancer?

Klement RJ, Kammerer U.

This paper can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/22029671

Dr. Rainer J Klement from the University Hospital of Wurzburg reviewed the evidence of 162 scientific papers regarding the subject of carbohydrate restriction and cancer.

Dr. Klement found:

• Cancer, which might be considered a disease of civilization, was very rare among uncivilized hunter-gatherer societies. Their diet was mainly meat and fat, whereas modern diets have quickly changed to easily digestible carbohydrates derived mainly from grains. Our genes have not had time to adapt to the new carbohydrate foods, and diseases of civilization have ensued.
• Reducing the amount of dietary carbohydrates could stop, or at least delay, the emergence of cancer, and that growth of already existing cancer could be slowed down.
• Most carbohydrates are converted into glucose by the body. Most cancer cells depend on glucose for growth as their ability to use fats or ketone bodies has been impaired.
• High carbohydrate diets cause a rise in insulin and insulin like growth factor levels which promote cancer growth.
• Ketone bodies that are elevated when insulin and blood glucose levels are low, have been found to stop cancer cells growing.

Dr. Klement concludes that the evidence presented in the review shows that reduction of the high carbohydrate intake in modern diets may play an important role in cancer prevention.

The study investigated whether diets high in foods that increase after meal glucose levels are associated with an increased risk of pancreatic cancer. The dietary habits of 88,802 women were analysed over an 18 year period.

The study found:
(a) The women who ate the most carbohydrates had a 30% increased risk of pancreatic cancer compared to the women who ate the least.
(b) The women who ate foods with the highest glycemic load values had a 53% increased risk of pancreatic cancer compared to the women who ate foods with the lowest glycemic load values.
(c)  The women who ate the most fructose (fruit sugar)  had a 57% increased risk of pancreatic cancer compared to the women who ate the least.

The study shows that women who eat a high carbohydrate diet, especially one with foods with high glycemic load values, have increased rates of pancreatic cancer.

This study investigated the association between carbohydrate consumption and colon cancer. The study contained 473 people with colon cancer and 1,192 men and women without colon cancer.

The study found:
(a) Men who consumed the most carbohydrates had a 70% increased risk of colon cancer compared to men who consumed the least.
(b) Women who consumed the most carbohydrates had a 170% increased risk of colon cancer compared to women who consumed the least.

This study reveals that a high carbohydrate diet leads to a significant increase in colon cancer.

Research by a Nobel prize winner shows that high carbohydrate diets cause cancer

On the origin of cancer cells
Warburg O

This paper can be accessed at: http://www.sciencemag.org/content/123/3191/309.extract

Otto Warburg won the Nobel prize for medicine in 1931 for discovering that cancer cells are fundamentally different compared to healthy cells.

He found that energy and growth in cancer cells is mainly generated by the fermentation of glucose, unlike normal cells which contain tiny organelles inside them called mitochondria which work away producing enegy to keep the cells healthy. The mitochohdrial activity in cancer cells is impaired and cancer cells can use glucose by up to 200 fold the rate of healthy cells.

How does this relate to cancer and diet?

To produce energy humans mainly use either:
(i) Fat and ketone bodies.
(ii) Glucose.

Fat may be provided by dietary fat, and ketone bodies are compounds that are produced when fats are broken down for energy by the liver and kidneys. Almost all carbohydrates are broken down by the body into glucose.

Fat and ketone bodies need mitochondria to provide energy, whilst glucose also has the ability to provide energy by fermentation. This means that fat, ketone bodies and glucose can be used for energy by healthy cells, but only glucose can be used by cancer cells.

The implication of this is if you follow a very low carbohydrate diet it is very difficult for cancerous cells to survive because they will have little or no energy to feed on.

Warburgs research shows that a high carbohydrate diet will encourage cancer growth, whereas a diet low in carbohydrate and high in fat discourages the growth of cancer.

This study tested the hypothesis that higher glucose levels predict shorter survival time and time to recurrence in ovarian cancer patients. 199 patients with ovarian cancer were included in the study.

The study found:

(a) For every increase of 70 mg/dL of blood glucose levels, a patient was 2 times more likely to die of ovarian cancer.

(b) For every increase of 70 mg/dL of blood glucose levels, a patient was 2.32 times more likely to have a recurrence of ovarian cancer.

This study shows that higher blood glucose levels are associated with higher rates of ovarian cancer.

High carbohydrate diets contribute to high blood glucose  levels. See here.

The study found that higher glucose levels were associated with shorter survival times in ovarian cancer patients.

Krone notes that high intakes of sugar and refined carbohydrates and elevated blood glucose are strongly associated with the risk of cancer.

This study sought to find out if sugar and refined carbohydrates and elevated blood glucose were also associated with poorer survival rates after diagnosis of breast cancer.

Krone measured blood sugar in a group of cancer patients (some with active disease and some in remission) and found a significant lower average blood glucose in those in remission. 

This study shows that high intakes of sugar and refined carbohydrates and elevated blood sugar are strongly associated with the risk of cancer , and is also associated with poorer survival after diagnosis for early breast cancer.

This 9 year study of 62,739 postmenopausal women investigated the relationship between carbohydrate consumption and breast cancer.

The study found:

(a) Overweight women consuming the highest amounts of rapidly absorbed carbohydrates had a 35% increased risk of breast  cancer.

(b) Women with largest waist circumference consuming the highest amounts of carbohydrates had a 28% increased risk of breast  cancer. 

(c) Carbohydrate intake was also associated with estrogen receptor-negative breast cancer.

The study shows that rapidly absorbed carbohydrates are associated with postmenopausal breast cancer risk among overweight women and women with a large waist circumference.

The colonisation of Europe and our Western diseases.

Lutz WJ.

This paper can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/8531831

Lutz says modern civilisatory diseases such as heart disease and cancer is usually blamed on the adverse effects of animal fat and cholesterol. However the 'field studies' themselves, undertaken to support this theory, failed.

As the last environmental changes in human history are agriculture and rise of carbohydrate intake (and therefore a concurrent reduction of fat and protein consumption), Lutz suggests that the carbohydrates rather than the animal fats cause our civilisatory diseases.

Agriculture (and higher carbohydrate consumption) started in the Arabian Peninsula and spread across Europe to arrive in countries such as Northern Ireland, Scotland and Finland last. So people in the Arabian Peninsula have had a longer time to adapt to the increase in carbohydrates compared to the people in the far West and North of Europe and this is reflected in the fact that countries such as Northern Ireland, Scotland and Finland suffer the most from heart disease and cancer.
