appears the AICR is not basing their recommendations on the latest information. carbohydrates feed cancer. their recommendations do not appear to restrict carbs at all, in fact they almost seem emphasized.
The latest information doesn't necessarily mean the most reliable information. I have not been able to find any reliable evidence that carbohydrates feed cancer. All I have seen are a few zealots with unsupported theories. If carbohydrates feed cancer then we should stop eating all vegetables and eat nothing but meat and fat. There are 3 macro-nutrients......protein, carbohydrates, and fat. Carbohyrates are the only macro-nutrient that feed the brain. They are also critical for proper functioning of many vital organs including the liver, kidneys and intestines. The FDA, ACS, ADA, and any licensed dietitian have always and still do recommend that carbohydrates (in the form of vegetables, fruits, and whole grains) comprise over half of our nutritional intake. Everything we eat, whether it is carbohydrate, protein, or fat, eventually is converted to sugar in order for our bodies to be able to use it as fuel. All reliable nutrition sources including AICR recommend limiting simple sugar intake. But simple sugars are only one type of carbohydrate. Unfortunately, a lot of people have come to equate refined sugar with carbohydrates and label them both as "bad" and just isn't true.

DUH!

I became hypoglycemic a while after last TX so I have to keep my 'sugar' level up. So yes I do work at keeping 'sugar' levels within normal with my balanced diet which includes a lot of FRESH veggies and fruit but there are times I have to resort to 'sweets' to keep the level up.0 -

technically there is no minimum requirement for carbohydrates in the diet. humans can survive without it. the body can produce glucose from protein through a liver process called gluconeogenisis. the body will produce glucose in this way when it needs it but it will be very small amounts. fat is actually a very good source of energy for the body. that is why it is stored in this form, not as a carbohydrate.
when doctors want to image for cancer, they often order PET scans with a dose of oral glucose beforehand. the glucose they use causes cancer cells to light up on PET scans. all forms of carbohydrate break down to glucose.

Bottom line is, if people are starved of glucose, people die.
All proteins and fat turn into glucose in the blood too. Eating a diet free of low in carbohydrates is not healthy. It can lead to many life threatening problems including blocked arteries, heart failure, stroke, high blood pressure, gastro intestinal disorders, and the list goes on and on. Managing blood glucose levels is certainly healthful, but that isn't done by by not eating carbohydrates. And not eating carbohydrates does not prevent or cure cancer.

i am curious if you bothered to to look at the links i posted? the evidence is pretty compelling that starving cancer cells of glucose causes those cells to die.
btw, fat is not turned to glucose. because the body can create glucose from protein, we do not technically need to eat carbohydrates. converting protein to glucose only creates small amounts of glucose comapred to getting it from food. also, i am not saying EVERYONE should avoid carbs. i am saying people with cancer or recovering from cancer should drastically reduce their carb intake especially high glycemic index carbs.0 -

if you really want to prevent cancer, it is well worth your time to look at that material. problem is, dieticians keep making the same recommendations and cancer rates continue to grow.
Quoted from the article you cited:
"Graeber and his colleagues demonstrate that glucose starvation -- that is, depriving cancer cells of glucose -- activates a metabolic and signaling amplification loop that leads to cancer cell death as a result of the toxic accumulation of reactive oxygen species, the cell-damaging molecules and ions targeted by antioxidants like vitamin C."
This study has nothing to do with diet and nutrition. It is about how glucose affects cells. As you and I have both said, everything we eat converts to glucose to provide fuel. The results of this study suggest possibilities for further research to develop drugs that can target cancer cells by preventing or reducing the amount of glucose available to cancer cells. That has absolutely nothing to do with what we eat.
And quoted from your second cite:
"Researchers at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute have designed an experimental drug that chokes off that sugar supply, causing the cells to self destruct.
The agent, called OSU-CG12, is an example of a new class of anticancer drugs called energy-restriction mimetic agents. It is described in a paper published recently in the Journal of Biological Chemistry."
Once again, the effort is to develop targeted drug therapies that can prohibit glucose from entering cancer cells while allowing the glucose to enter healthy cells. Without glucose, the healthy cells would die and we would die along with them. In any case, this has nothing to do with what you do or don't eat.0 -

We need carbohydrates in our diet for much more than just producing glucose.
Underproduction of glucose is hypoglycemia which can be life threatening.
Fat is turned into glucose. It just takes a little longer (we are talking a difference of a couple of hours).
The glycemic index, while a useful general tool can be misleading. The number assigned to any food in the index is actually an estimated average not an absolute. The glycemic effect of a piece or bread or potato for instance varies more depending on what other foods it is eaten with than the inherent "carbohydrateness" of the food itself.0 -

not everything converts to glucose, only protein and carbohydrates. protein converts to glucose at very small rates. small enough that it only provides enough glucose for the small amounts required by the healthy body. for the people who do not want to sit around waiting for a magic pill to come onto the market, it would be wise to restrict carbohydrate to help manage, avoid, and/or fight cancer.

you are right about GI but it is typically a decent guideline to use when assessing how much something raises blood glucose levels. i found this interesting:

I eat anything I want! Now because my taste buds are out of whack due to chemo, again, I am limited as to what tastes good...I've lost 25 pounds that I didn't need to lose...okay maybe 10 was okay...lol. So I tend to eat whatever I can over and over....some things taste normal others, no...

It is true that excess fat not needed for energy stays stored as fat in the body until and if it is needed for energy, this is not a good thing. Excess body fat leads to obesity which actually puts us at a higher risk for diabetes, some cancers, and many heart and blood related illnesses. Excess protein can also lead to many medical problems including kidney failure, dehydration, and ketosis, not to mention that many essential vitamins are non-existent in protein/fat foods.
Eating a healthy balanced diet is beneficial in many, many ways, including lowering the risk of cancer. Eliminating/restricting carbohydrates from your diet just doesn't accomplish that and does more harm than good. Your diet is systemic; that is, it effects all systems of your body equally and you can't tell the food you eat to only act on cancer cells. By the same token, you can't substitute diet for targeted drugs that are able to act on just a certain body system or type of cell. You can literally kill yourself trying.
A key component of the recommendation for macronutrients is how they are distributed in the diet; in other words, the percent of calories coming from protein, carbohydrate and fat. The DRIs (Dietary Reference Intakes, formerly known as RDA (Recommended Daily Allowance)) express this distribution as the Acceptable Macronutrient Distribution Range or AMDR.
Acceptable Macronutrient Distribution Ranges for Adults (as a percentage of Calories) are as follows:
Protein: 10-35%
Fat: 20-35%
Carbohydrate: 45-65%
Deliberately and significantly altering this balance over a prolonged period of time isn't going to do a thing to prevent or cure cancer, but it will do harm in many ways.
While I am certified in teaching nutrition, I am not asking you to take my word for any of this. But please, take all this internet information you have been citing to a doctor or nutritionist or dietitian that your know and trust before you harm yourself. I am sure you don't want to do that because of misinterpretation of information. Please get a second opinion from someone who is trained and experienced in the field of nutrition.0 -

Bubba,What is your cancerMAJW said:Pops..double post
Sorry
Bubba,
What is your cancer diagnosis? I didn't see anything on your profile so I am curious about your stage, grade, type of breast cancer. Are you in treatment now? Please introduce yourself to us.
I think it is great to open a dialog about nutrition and you and Nancy both seem to have knowledge about each of your positions. I always appreciate hearing different views on every aspect of cancer.
But the one thing that you haven't mentioned is that your oncologist, doctor have made these recommendations or supported them for your cancer. Do they feel that this is the best way for you to fight your cancer? Or are you not fighting cancer and just here to advise us how we should fight our cancers? Because if that is the case then we can take your suggestions back to our doctors and see how they feel about them. As a diabetic and cancer survivor my doctors recommend a balanced diet (including carbs), exercise, and regular doctor visits to my oncologists and PCP. So that is what I will continue to do.
Thank you for expressing your views and the many links you have provided.

Maybe I still still don't have a good handle on the culture of this site. I thought it was also for the exchange of information and experiences. I am an admitted info junkie and info sharing is a strong suit for me while emotional support, not so much. I see this thread as an exchange of information, not a slap fight, but I apologize if it has made you uncomfortable.0
