    Does sugar "feed" cancer cells?

    I've heard differing opinions about this since I was diagnosed. My oncologists said no, but that everyone should watch their sugar intake.

    I don't have a link, but heard something on the radio yesterday about a new study showing a link.

      Of course there is a link. Sugar use is how pet scans work. Every bit of food you eat must be turned into a simple sugar first or your body/cells cant make use of it as a fuel.

      The controversy is over sugars which are eaten after being extracted from their 'containers'.

      One can suck on/chew sugar cane all day and feel no untoward side effects because the fiber is being consumed along with the sweet. Remove the fiber and eat the sugar directly and alone and we have quite a different story about a body's reaction.

      When I had cancer, my blood sugar was terribly low, my oncologist explained that cancer grows on sugar. It takes is away from your normal cells. "Refined" is the operative word anything processed or refined is not good for you. Try eating organic raw sugar. That will naturally cut down on your sugar intake as it is rather pricey

      Here is an article from a Dietician that specializes in Oncology. The title sums it up. "Why You Should Stop Saying Sugar Feeds Cancer"

      And, here is an article we posted three years ago about this subject

      And, another of our articles on the "sugar" subject.

      GregP has given you some good references and some food for thought. Do your own research on the net and draw your conclusions. I have read articles that have concluded that too high a sugar intake can be harmful to your body, one souce would be WebMD. I have decreased my overall sugar intake since my diagnosis and find myself carefully reading labels. You would be surprised where added sugars hide in our food supply and under what names. Having said all of this, I still enjoy my treats and they are all the more enjoyable when I do not have them as often.

      Cancer cells have way more insulin receptors on them so it needs more sugar to survive. Keep your blood sugars at low normal and eat mostly plant foods with lots of fiber. Also fish and other animal protein and nuts are ok but I'd stick with fish.....And Pet scans use sugar and radio active material and the cancer cells gobble it up. BUT Who knows what's what...Eat lots of every color veggie and fruit you can stuff down your gullet as they have cancer fighters....

      Thanks everyone, and thanks for the links GregP. I was going to be seeing my mom over the weekend and thought she might have heard about the studies and would bring it up.

      Like Greg, I was given a website to refer to when I asked the onc about it. Our bodies need sugar, but what we need to avoid is too much processed sugar or any other foods.

      Your body turns everything into sugar.

      My oncologist laughs at the idea that eating sugar causes cancer or causes cancer to grow. There sure are a lot of healthy eaters around who, despite their fabulous eating habits, have or had cancer.

      You can't believe everything you hear or read. (And, i would add that if you trust what we say here on WN more than you trust your oncologist, it just might be time to find a new doctor.)

      If it were true, I wouldn't be a cancer survivor. I'd be long gone. My oncologist (top doc from top cancer research center) told me no from the get-go despite what several of my friends insisted.

      LiveWithCancer, I agree that if I did trust what I read here more then my doctors, it would be time to move on! Like I said, I had an idea my mom would bring it up and referring her to websites is often helpful.

      Discovering that there is a correlation, a link between 2 events, is far different than saying one caused the other.

      There is an old trick of macheavellian thinkers who twist a word (like changing "link" to "cause") and divert attention from a truism through ridicule in order to suppress whatever it is they want supressed.

      An old saw says that Truth is first ridiculed, then vilified, and finally accepted as an ordinary fact despite the twisted desires of demagogues and other control freaks.

      This is how the flat earth theory and Intelligent Design remain, as some believe, viable options of discussion.

      I just stay away from all those artificial sweeteners, raw organic sugar if needed in my 3 cup a day coffee habit, everything else is fruit and colored veggies, stay away from anything corn syrup or high fructose.
