For the umpteenth time....with different cancers, and population studies, over and over...there is a correlation between sugar and cancer.

Dr. Lewis Cantley. Weill-Cornell
High-Fructose Corn Syrup Promotes Colon Tumor Growth in Mice

https://news.weill.cornell.edu/news...-growth-in-mice

Quote:
NEW YORK (March 21, 2019)—Consuming the equivalent of one can of soda per day caused mice predisposed to colon cancer to develop larger tumors, according to a study by Weill Cornell Medicine and NewYork-Presbyterian investigators.

The study, published March 22 in the print issue of Science, shows how high-fructose corn syrup fuels the growth of colon tumors in these mice and demonstrated a potential strategy to block this excess tumor growth. Though more study is needed to demonstrate whether high-fructose corn syrup promotes colon tumor growth in humans, the findings might have implications for cancer treatment or prevention.

“The study shows that colorectal polyps feed on high-fructose corn syrup and explains the molecular mechanism by which this drives the growth of the tumor,” said co-senior author Dr. Lewis Cantley, the Meyer Director of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine and NewYork-Presbyterian. “While our work was conducted in mice, our findings build on mounting evidence that sugar fuels cancer growth.”

Investigators say that, based on their findings, people with colon cancer or those at high risk should avoid sugary drinks.




Sickeningly Sweet

Biochemist Dr. Lewis Cantley is Finding Increasing Evidence of a Strong Connection Between Sugar and Cancer
(in Weill Cornell Medicine Winter magazine)

https://news.weill.cornell.edu/news...ckeningly-sweet

Quote:
Dr. Lewis Cantley hasn’t eaten sugar in decades. “I have a very simple rule,” he says. “I eat fruit, but I don’t eat anything that has sugar added to it. And I guarantee everybody would be better off if they ate zero sugar.”

Swearing off sugar may sound like a difficult proposition in a society where the sweet stuff—in Halloween candy or birthday cake, breakfast cereal or caramel macchiatos—is not only ubiquitous but central to our daily rituals and major celebrations. Indeed, according to the World Health Organization, the average American consumes 126 grams of sugar a day, more than people in any other country and nearly four times what nutritionists recommend. “It’s an addiction,” maintains Dr. Cantley, the Meyer Director of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine, who was inspired to become a sugar teetotaler when he saw friends and relatives struggling with their weight in the ’70s, at the dawn of the American obesity epidemic. “If I say to someone, ‘Don’t eat anything sweet for two days,’ they’ll look at me like, ‘That’s impossible, nobody can do that.’ It’s very much like an opioid addiction or an addiction to nicotine.”

Again, thanks for posting these findings, JEY.

I do struggle with" what is the difference between carbs, fruit sugars and cane sugar" for cancer cell fuels. Is fruit sugar really safer than cane sugar??

Colon cancer is the one I do worry about.

I truly believe if I had not gotten off of sugar 100% that I would have colon cancer. Every time I don't eat sugar I know that I am doing everything I can to starve it of the food it craves.

I know, now that I am back to both losing excess weight, and really watching carbs, that this can only help me with my bladder cancer.

I struggle with it too...yesterday before I saw this study I was listening to Dr. William Li (new book Eat to Beat Disease) on Dr. Hyman's Farmacy podcast. All plant based, all fruit, etc. he says "accepted" the best diet for cancer prevention. Really? The way he was describing it seemed over a 100g carbs.

You can allow a small amount of fruits in a Keto for Cancer diet, if you limit each meal to around 6g carbs. Miriam Kalamain has also many vegetables in her diet, but the amounts are limited. Still my favorite diet for cancer prevention: https://www.dietarytherapies.com/foods

This is in line with the orange juice ( to take daily dose of Konsyl) the GI specialist recommended to prevent colon cancer.

Dietary Therapies is right in line with DANDR which allows for a few berries. Frozen packages of berries makes for easier portions IMO. Fresh blackberries encourage coming back for more.

Recently pick up a bag of Gala apples for school lunches, and I liked that the apples were rather small. The market push is for HUGE apples; and cutting one in half or quarters leaves a browning, unpleasant second, third and fourth serving. Though sometimes, I will take the portion I want and give remainder to my kids or the dog. Small apples are a welcome portion size.

Thank you for this. I find it fascinating that my mother had (both endometrial and) breast cancer and now I have bladder cancer - two of which are mentioned in this article re the discovery of the significance of the P13K enzyme when mutated, with the Dr. who discovered it, now doing research into a diet & med based on that discovery, in the treatment of women with endometrial cancer.

I would love to know if I have the gene that allows that enzyme to mutate. Bet I do.

I was surprised when told at diagnosis that a history of various cancer on the father's side also raised breast cancer risk, because I had none on mother's side, so some inherited mutations might be at play?

Exciting news...D. Colin Champ has written a summary article for DietDoctor and appears he will be writing more on the topic of cancer.

Adding further difficulties to this potential link is the fact that red meat and processed meat are entirely different entities and should not be conflated. For instance, a meal containing beef from grain-fed cows versus wild game meat results in a markedly different physiologic response, with the grain-fed meat increasing several markers of inflammation.8


I came to this conclusion some time ago.

Quote:
The potential of burnt food to become carcinogenic in the colon is a major reason why the colon cancer-red meat link has been studied so vigorously. Yet, even this association has yielded a potential overall increased risk of colon cancer under 1%.10


At least one European country dictates the level of "burnt" on the french fries for this reason. Info discussed on a PBS cooking show. The color of the french fries are regulated to prevent colon cancer.

New podcast interview with Dr. Thomas Seyfried.

Quote:
Cancer Treatment May Be Harming You

Carl and Carrie visit Professor Thomas Seyfried in Boston, who believes that standard radiation treatment may be killing brain tumor patients.


Some of his claims about standard of care are quite upsetting, and not just for brain cancer.
