Low-carb (and lower sugar) diets may soon look a lot better to colorectal cancer survivors. In a recent data-rich study of more than 1000 stage III colon cancer survivors, researchers from Dana-Farber Cancer Institute found that those who consistently ate a high-carbohydrate, sugar-laden diet appeared to have markedly higher recurrence rates of their disease than patients whose diets were more varied and contained less-sugar. The results were published in the Nov. 7 Journal of the National Cancer Institute.

The main finding after surveying and following 1,011 patients during and 6 months after chemotherapy? That those who reported having the highest dietary levels of carbohydrate intake (and related glycemic load) also had an 80 percent increased risk of colon cancer recurrence or death compared with those who had the lowest carb diets.

 But because cancer patients (and health-minded others) are advised not to make a nutritional or lifestyle change based on just one research study or peer-reviewed journal article, it’s worth noting that in the Feb. 7^th issue of Nature, doctors from the University of California-San Francisco (UCSF) argued that sugar effects are so detrimental that the substance should be regulated like alcohol and tobacco to protect consumers’ health.  Read the rest of this entry »

Fewer people in the U.S. are getting colorectal cancer (CRC), but that progress is seen much more often in well-off and highly educated Americans. In fact, the gap is widening in rate of colorectal deaths in people with less education and/or who live in deeply disadvantaged communities.

Researchers now have shown that differences in weight, diet and physical activity play a huge role in the higher rates and deaths from CRC among people of lower socioeconomic status.

In a paper published in the Sept. 4 2012 Journal of the National Cancer Institute, a careful statistical analysis of  a 10-year observational study of a half-million people indicated that helping people of lower education or income to change their diet, body weight, smoking and physical activity could be nearly as important as improved screening for reducing CRC deaths.

TO EAT OR NOT TO EAT…DURING CHEMOTHERAPY

To humbly paraphrase Shakespeare, the question is “whether ‘tis better to…ban sugar from your diet, or bulk up on high-protein meals…” The internet is full of raging debates, fervid testimonials and opinions about what you should or shouldn’t eat when you’re being treated for cancer.

 One of the most common chat topics is whether you should cut out ‘sugar’ to decrease the amount of “fuel” available for voracious cancer cells.

If only cancer, and nutrition, were so simple. But every kind of calorie is fuel, every cell uses fuel, and cells become cancerous in many different ways.  

But thankfully, scientists are working hard to shed more light (than heat) on the role that nutrients might play in cancer cells—and they’re coming up with some tantalizing clues, according to the most recent National Cancer Institute Cancer Bulletin (July 10 2012). Read the rest of this entry »

Summer’s over. The black squirrels in the front yard are scurrying around hunting acorns and my inbox is full of neat nuggets of colorectal cancer news — and I don’t want to leave them buried all winter.
