Depending on what you read Americans consume an average of 22 teaspoons of sugar per day, 2-3 pounds of sugar each week, or 135 lbs. of sugar per person per year! That is way too much.

Excess insulin is also provoked by excess cortisol due to being too stressed and not sleeping enough. Insulin is also a fat storage hormone, which in effect also will cause someone to "grow".

Sugar is acidifying, lowering the body's pH, and creating a wonderful environment for yeast, fungus, bacteria, viruses, parasites, and cancer.

If people would just stop drinking soda it would save billions in medical costs and prevent untold suffering.

Jackie's advise is excellent. Why not start implementing her suggestions before you get cancer?

I wish you could be interviewed on TV, on shows like Oprah and Dr. Oz, to share this information with the American Public. Thank you for posting this much needed information.
Ironically, even renowned cancer treatment centers often have cafes and coffee bars that sell high glycemic food in abundance. Soemhow, there is a disconeect between what the research shows and what the Health care systems are expressly and implicitly educating patients to eat to prevent cancer growth and cancer spread.

I'm doing all the right things that were listed, but my fasting glucose is 99. I guess it's more exercise for me! Thanks for listing the optimal ranges.

I don't eat a lot of sugar but when you say "No more X,Y,Z" that is a bit extreme. I want to enjoy life. Never have another ice cream cone? I don't think so.

Thanks for the great comments, everyone! It is wonderful to hear that people are realizing the dangers of eating too much sugar.

Sometimes I get a bit of resistance from some people when I begin to educate them about sugar. To them, saying no more refined sugar seems a bit extreme. However, to leave cancer unchecked and to continue to eat an unhealthy diet is asking for trouble. The food you put in your mouth can be as important as the medicine you take to help fight cancer. Our goal is to teach you to eat foods that help to fight cancer in one way or another. Simply put, foods like sugar, candy, soda, ice cream, white bread, and white rice do not contribute anything to your body to help fight cancer.

Does that mean you can never have these foods again? Well, if I said no then I would not be doing my job as a Life Over Cancer dietitian - LOL! But utimately, what you eat is entirely up to you. Remember, choosing life over cancer means enjoying life but not at the expense of promoting your cancer!

You are so right about Tumors and Sugar. I have Cancer and one of my tumors is huge. It grows like crazy if I slip and have something with sugar in it.

Thank you for this clear explanation and for your continued encouragement for people to choose to eat nutritious foods and take good care of their bodies.

I've cut out most man-made "foods" and feel great, but when I do have the processed stuff, boy do I get bloated and uncomfortable!

I agree with Kristen's post, and there are too many examples of what she described. Earlier today, I looked at a website sponsored by a heavily-advertised cancer treatment group, and they featured a recipe for Caramel Nut Popcorn, using 2 bags of microwave popcorn, a half-cup of brown sugar, salt, butter, and brown rice syrup (more sweetener). Some almonds and unsweetened coconut appeared to be the ingredients that led their chefs to promote this as a healthful snack. UGH! It does not sound like a wise choice for people trying to make their way from cancerous to healthy.

Again, thank you Jacki and Dr. Block for your stellar research and efforts!

Yeah, I'm so glad to see this post. More people need to know about this!

I actually interviewed Dr. Block about the sugar-cancer connection for my book, Sugar Shock.

Listen, I'm trying to reach Dr. Block again to invite him to be on my Gab with the Gurus Radio Show to discuss this. Can you please help me connect with him. I couldn't get through on the office phone number. Thanks.

people say they can't live without sugar, sweetners, etc. how about birch tree based xylitol.. its a win win sweetener,
takes plaque off your teeth, and doesn't cause doesn't cause diabetes!

Very nice article. Jacki, are you part of the Oncology DPG? They have a nice listserv that I think you might like to respond on sometimes.

I woke from a deep sleep early one morning hearing the words "cancer feeds on sugar". I researched on-line and found that it does. At that time I was not diagnosed with cancer, although I did have a sore on my forehead that would not go away. A couple weeks later I had it checked out and it was basil cell, skin cancer. I have quit eating sugar now for one month, all sugar. I read every label, if it contains sugar or substitute sugar I don't eat it. Are there specific cancers that feed on sugar, or just all cancers? I believe in God, and believe those words were spoken to me from Him.

Thanks for sharing some good info related to healthy foods . for weight loss try to drink more and more water and never eat ur food before going in bed because that will caused u to gain weight ...

Is this an ongoing current blog? The last entry I see is in 2011. Do you recommend against having a PET scan because of the cancer cell's avidity for glucose?

Jacki: What about for cancers that do not image with glucose dye? I have MTC, Medullary Thyroid Cancer, c-cell cancer, and I know that it is a challenge for docs to see tumors as they spread because they say this type of tumor does not light up with sugar. Are their some cancers that are less affected, or not fed by, sugar? Thanks, Lisa
