Study: Cut Alcohol, Up Plant Foods for Lower Cancer Risk

Low alcohol consumption and a plant-based diet, part of AICR’s Recommendations for Cancer Prevention, are associated with reducing the risk of colorectal and other obesity-related cancers, finds a new study, adding to a growing body of independent research on how following AICR’s recommendations links to lower cancer risk, longer survival, and improved overall health.Wines_FD001551_7

This latest study was published in Cancer Causes & Control. You can read more about the other studies investigating AICR recommendations here.

The Cancer Causes & Control study included almost 3,000 cancer-free adults who had no history of cancer. Participants were part of the ongoing Framingham Heart Study. Back in 1991, everyone filled out a questionnaire about how much they weighed, what they ate and their activity habits.

After almost 12 years, 480 of the participants had developed an obesity-related cancer, such as colorectal or breast.

Study researchers then scored how much participants met seven of AICR’s recommendations, giving them zero, half point or one point. The scoring included Continue reading


Organization: Possible key to bacterial invasion for some colon cancers

A growing body of evidence indicates that the trillions of bacteria that live in the digestive tract – might play a role in altering cancer risk. Now, a study suggests that how those bacteria are organized and where they are located in the gut might influence the risk of certain colon cancers.

BacteriaThe study, published in The Proceedings of the National Academies of Science, focused on biofilms – communities of bacteria that help bacteria communicate with each other and grow more efficiently.

When bacteria organize into biofilms, they can breach the protective inner layer in the gut and invade the local tissue, promoting inflammation and possibly cancer.

We have an interesting relationship with the bacteria in our gut. Although many of the microbes provide beneficial services, bacteria – both “good” and “bad” – can cause us harm, so we keep them all at arm’s length, so to speak. Normal, healthy tissue in the colon is coated with a two-layered covering of mucus –a mesh-like outer layer and a gel-like inner layer. Whereas the outer layer creates a moist, cozy environment for bacteria, the inner layer is less hospitable: it provides the last line of defense against their invasion.

Less Red and Processed Meat? New Guidelines May Help Reduce Cancer Risk

16939621_sThis year, for the first time, the US Dietary Guidelines committee may recommend that Americans eat less red and processed meat, a key recommendation from AICR for lowering cancer risk. Every five years, the US Dietary Guidelines are updated based on the committee recommendations and they are due out this year.

According to reports from the committee’s most recent discussions, the 2015 nutrition and eating guidelines may also call for Americans to eat more plant foods, like vegetables, fruit, beans and whole grains, also an AICR recommendation. Research shows that eating patterns like this – more plant foods and minimal red meat –  can help prevent obesity and chronic diseases like cancer, type 2 diabetes and heart disease.

These 2015 guidelines may also call for lower sodium and specific limits on added sugars.

If enacted, these recommendations will better align with AICR’s Recommendations for Cancer Prevention and could, in the long-term, lead to fewer cancer cases. AICR estimates that about 1/3 of the most common cancer cases every year in the US wouldn’t happen if Americans followed a healthy diet, were physically active every day and maintained a healthy weight.

Guidelines like this will inform dietary advice for individuals, but will also set in motion changes for school lunches and other government food and nutrition programs. Read more about the guidelines at health.gov.
