Ok, I really would like some medical literature that shows sugar feeds the Cancer. Dads Oncologist and PCP told him to eat anything he wants and since sweets is what he wants he eats alot of them. It seems to be what tastes good to him.
My understanding of digestion is that all food breaksdown and enters the bloodstream as glucose, protein, and fatty acids. If you eat a slice of whole wheat bread it still is going to become glucose(sugar) in the blood stream. Is there some study that I can read that proves the theory that sugar feeds cancer? Dad and I need proof. I certainly dont want him to stop something he enjoys if it is not necessary.

Well I heard that sugar was bad also. I ate alot of sweets alot of them .... I'm stage 4 lung cancer and I have been ned for 7 months. I love chocolate and I ate it along with cupcakes . I ate good food also but I felt better after treatment when I ate sugar. Maybe for so me cancers it's not so good but it didn't hurt me. I would like to know whats behind the sugar thing also???????

Amen. I'll be watching your replies.

Dear Dana:

First thing would be to speak to your dad's Oncologist.

There has been much discussion about sugar and of course I was concerned as well. The first thing I did was speak to my Oncologist, and he told me that it was a myth. He said the only organ that needs sugar is your brain, and if it doesn't get it from sugar, it will get it the same way you described the bread.

Also, sugar goes through your blood stream probably quicker than any other substance (sugar rush) so it makes perfect sense to use radioactive glucose for a Pet Scan.

I do not eat a huge amount of sugar but I don't avoid it either. Others at LCA do believe that diet is a huge issue, and I do agree that a balanced diet is very important. However, I don't deprive myself of anything. Hope this helps somehow.
****Many Hugs*****

Me too! My doc said eat anything I could eat- sometimes I really crave chocolate- and chicken!!!!
I cheat on the chocolate tho- I buy a bag of Hershey kisses- throw em' in the freezer- take out JUST ONE when the urge hits- and have it with a cup of coffee...(this was an old Weight Watcher's trick) and sometimes just one will curb the craving- the hard part is NOT eating the whole bag.... hahaha!!!!

I cannot believe that some of your doctors are telling you to eat whatever you want. All high carbohydrates that metabolize into sugar in your system should be avoided. There are thousands of articles about this but here's one simple one that makes an awful lot of sense (well to me anyway) and includes a link to a 'cancer diet'. Of course it's your call.

Thanks to all who responded. It helps to get other experiences and opinions on this issue. I hope you all have a great great day. Our Chemo and Rad. Oncologist both believe it to be a myth. so I say let him it cake!!

Its totally your call but i have changed my diet and believe i get through chemo better that way. There are many people who have gone and changed their diet and have gone into remission. Everyone is different, but you have to believe there is something wrong in our bodies that we became susceptible to cancer and therefore we should change that.
Good luck x

Honestly, after all of the years of research that I have done on this subject, due to my own father's NSCLC, I have concluded that this is the only way to go - diet wise. My father added a lot of good things to his diet, because of my suggestions, but he never gave up the foods he loved and there were many 'bad' ones. I really think you have to take drastic measures with diet in order to receive any noticeable results. Again - this is only my opinion - but if you were to really research all of the toxins we are exposed to (and many through what we eat), as well as unhealthy foods (and vitamin deficiency through heating) it would only make sense that one needs to eliminate as many of them as possible in order to heal.

Raw vegetables and vegetable juices, fruit (fresh and dried but rehydrated—avoid sulphurated), whole grains, lightly cooked vegetables, sweet potatoes, white potatoes, beans, yogurt and kefir, small amounts of organically raised meat, small amounts of poached fish, nuts and/or nut milks, herb teas, vegetable soup, and cruciferous vegetables. Cancer experts recommend a 70% raw food diet (uncooked), however, others seem to feel that 50% is recommended.

Researchers at University of Texas M.D. Anderson Cancer Center have found that EGFR plays a second role in promoting the survival of cancer cells. It can help tumor cells get a constant and plentiful supply of the sugar glucose, a critical nutrient. Despite interference from the targeted drugs, EGFR also can help the cancer cells thrive by helping to assure their food supply (glucose).

Drugs like Erbitux, Avastin, Tarceva, Iressa, and Vectibix by blocking this receptor disrupts cellular signals that cause signals that cause tumor cells to grow and proliferate. They work by preventing the enzyme tyrosine kinase from launching a signaling cascade that fuels tumor cell growth.

But generally limited responses of 10% to 20% to these treatments have casued cancer experts to wonder if EGFR's role in the disease is limited as well. EGFR could play a second role in promoting the survival of cancer cells. It helps tumor cells get a constant and plentiful supply of the sugar glucose, a critical nutrient.

EGFR does this by binding to and stabilizing another protein on the cell surface called SGLT1 (sodium/glucose co-transporter). Without this mechanism, the cell will undergo glucose starvation (the cell essentially devours itself and dies).

The glucose role is independent and thus unaffected by turning off the kinase-activated growth signals. Even with drugs that block the kinase activity, the tumor cell that expresses very high levels of EGFR and very high levels of SGLT1 will remain viable.

It is surprizing to me that despite the fact that more and more chronic conditions like heart disease, diabetes and Krohn's etc can be prevented and to some degree alleviated by diet, many people are in denial that diet could be important for the cancer patient. I think we should approach the sugar question from another angle. I remember a study produced by Sloan Kettering that confirms numerous other studies that cancer cells have a significant number of glucose receptors on them and metabolize sugar quickly, but the question is what you can reasonably do about it, since the body coverts even the whole foods and veg into glucose.

The thing here is that simple sugars go straight into the bloodstream causing insulin spikes and IGH spikes and then there is an opposite reaction that causes the lows. The adrenal system is overloaded and inflammation is also increased.

My recommendation (I know this to help as I have diabetic issues and have to control sugar in my bloodstream) is to eat lower glycemic index foods and moderate the simple sugar.

Chemo destroys the immune system and the immune system is an absolute first line defense against cancer. A healthy patient is better able to tolerate treatments. I don't think any oncologist would dispute this, however most don't take it to the next level and help patients eat in a way that supports the immune system. Most have only the one objective - keep your weight up at any cost. But you can keep weight up without taking a significant number of calories from simple sugar, processed food and saturated fat. Its just that a lot of supposed healthy diets are just not planned properly to provide calories and protein.

If you can get a nutritionist who is experienced in cancer treatment to help you plan a diet for a couple of months as an experiment, you will see your counts and energy go through the ceiling. (By the way - I am planning to run a half marathon in the spring. 18 mths ago I couldn't hardly walk around the mall)

You may not be cured of cancer but you will be generally healthier and better able to fight it. I want every little bit of help I can get!

Other than the sweet tooth. Dad does eat a balanced diet. He always has been concerned about his health, excerized and ate well. Its interesting when he was having his Chemo treatments his Oncologist said no raw fruits or vegetables due to a chance of getting Samonella from a decreased immune system. He of course is allowed to eat them now . He is also back at the gym three days a week. Tolerating Tarceva x 3 months and will have his next Pet scan Monday. I will keep you all posted and hope you all are having an awesome awesome day!!

Don't make yourself crazy with this. It sounds like your father leads a pretty healthy lifestyle. Balance is key ..Veggies, organic meats, limited processed foods, no cigarettes limit sugar intake... Candy bars are not causing cancer as far as i know but they sure are contributing to the diabetes epidemic in this country.

I think there is such a need to "control" this cancer thing, that some people are willing and eager to deprive themselves of basic pleasures of eating so they can believe they are doing something to change the outcome.

If all your doctors, and as a standard, doctors caring for cancer patients never mention limiting anything that you eat, why would people ignor that and go out and try to find something to keep them from throughly enjoying life? Many people make money off this nutritional propaganda and products.

Eat what you want when you want while you can and enjoy it- you don't know when the day may come that you may not be able to eat at all.

Carpe Diem!

Garbage in results in garbage out. The more healthy eating, the better the odds of healthy results. That seems to me to just be common sense.
Refined sugar is recently man made and totally empty totally lacking in nutrional value calories. The human body was not designed to handle this product as it did not exist in nature.

Within reason, I agree he should be able to eat what he wants. You have to be careful in interpreting the literature, and distinguishing what contributes to lung cancer, and what a patient can do now that he has the disease.

A fruit-based diet using beta-carotene has a mild protective effect, and those on such a diet have a reduced rate of lung cancer. However, a study using a beta-carotene drug for those with lung cancer found the drug did nothing, indeed, it appeared to make the condition worse.

There is some literature (not dealing with sugar specifically) that suggests diet can have a protective effect and conversely that poor diet, red meats for example, can have an adverse impact. Since lung cancer typically acrues over 25-30 years, the food impact represents the cumulative impact of 30 years of diet, and there even it still plays a relatively minor role compared with things like smoking and asbestos. What no one has been able to demonstrate to my knowledge, is that a change in diet for lung cancer, will alter the course of the disease.

I certainly would not discourage anyone from changing to a healthier diet. However, without specific evidence of a benefit, you may be reluctant to tell someone who is ill and confronting the many consequences of a difficult disease, that he should not partake of his favorite food.

Why Cancer Kills (and How to Keep It from Killing You)
Ironic as it seems, for many years cancer specialists had no idea why cancer killed patients. In some cases, major blood vessels were blocked by the tumor, or the heart was compressed. In most cases, though, the cause defied explanation. Then researchers concluded that death was caused by starvation; that is, the cancer was stealing nutrients from the rest of the body and the patients literally starved to death. Most have seen the emaciated condition of terminal cancer patients. They look like people found in Stalin’s gulag.
Armed with this new knowledge, doctors were still hesitant to feed the patients higher levels of nutrients, fearing it would also feed the cancer and make it grow faster. Finally, a few intrepid researchers tried high-nutrition feeding of terminal cancer patients and discovered two things.
One, they lived longer and two, their tumors did not grow any faster. A great number of studies have confirmed this finding.
Yet, animal studies found that certain nutrients could make tumors grow faster and make them more likely to metastasize. These nutrients included processed sugars and omega-6 oils. In fact, in some animals with transplanted human tumors, the tumors do not metastasize unless the animals are fed corn oil, which is an omega-6 oil.
I checked the diets being recommended by a number of cancer centers. To my astonishment, I found that they were recommending that their cancer patients eat doughnuts, cakes, pies, cheesecake, breads and a number of other sources of refined sugar. I remember in one instance, a cancer patient told me she was told her to eat anything she wanted . . . and that the important thing was not to lose weight. Incredible!
In 1994, I wrote a book entitled “ Excitotoxins: The Taste That Kills ,” on the harmful effects glutamate and aspartame additives cause to the brain. (For more information, go to my Web site Since then, scientists have discovered that a great number of glutamate receptors, the site where glutamate interacts with the cell, are found with some cancers.
Stimulating these receptors can make many common cancers grow much faster, become highly invasive, and much more deadly. This was first discovered with brain cancers (glioblastoma multiforme). When these tumors secreted a lot of glutamate, they grew 14 times faster than those that didn’t. Adding glutamate to the tumors made them suddenly invade the surrounding brain.
We now know that breast, prostate, melanoma, colorectal, lung, ovarian, rhabdomyosarcoma, pancreatic, and head and neck cancers all have glutamate receptors. Stimulating these receptors causes tumors to grow and invade surrounding tissue. Blocking the glutamate receptors can suddenly make the resistant cancer sensitive to chemotherapy.
The irony here is that glutamate additives are common in our foods. Processed foods frequently have several forms of glutamate additives added in high concentrations. Why? They are only used because they enhance the taste of foods.
No one is telling cancer patients that these additives enhance the growth of their cancers, interfere with conventional treatments, and stimulate tumor invasion and metastasis. To learn more about glutamate additives and how to avoid them, go here for information on how to get my special report “The Great Cancer Lie.”
Although glutamate additives aid the development and growth of cancer, many natural products, including quercetin and curcumin, protect against its development and spread. All are found in vegetables, and many can be purchased as supplement extracts. Learn more about the life-extending properties of supplements by reading my report “Key Vitamins that Save Your Heart, Prevent Cancer, and Keep You Living Long.” Go here for further information.
The bottom line is there are many things you can use to prevent and defeat cancer which I discuss in my special report “Prevent Cancer Before It’s Too

Here's an interesting article on the subject. It convinced me.

" Otto Warburg, Ph.D. More than 70 years ago, Dr. Warburg won the Nobel Prize in medicine when he discovered that cancer cells require glucose (sugar) for growth. All cells have a requirement for glucose, but cancer cells consume as much as 4 to 5 times more glucose than normal, healthy cells. In fact, they're unable to multiply rapidly without it."

I'm 27 months stage 4 and doing great. I stopped refined sugar and I truly believe it has made a difference. You get a lot of glucose anyway just from normal diet so I wasn't about to add any that was not necessary.
