Resistant Starch May Reduce Red-Meat Colorectal Cancer Risk

Eating high amounts of red meat increase risk of colorectal cancer while fiber-filled food reduces the risk, AICR research shows. Now comes a study that offers one possible explanation for both links, finding that diets high in red meat and a type of non-digestable fiber have opposite effects on a group of genetic molecules.Chuckwagon Chili Con Carne

The study was published in Cancer Prevention Research.

Study researchers focused on a type of fiber called resistant starch. Our bodies don’t digest resistant starch in the small intestine. Then in the gut, bacteria convert resistant starch into the compound butyrate. In lab studies, this compound protects against colon cancer.

For the study, 23 participants, ages 50 to 75, switched between two types of diets. In one diet each person was given 300 grams — about 10 ounces — of raw lean red meat a day. That’s about the equivalent of a cooked 8 ounce burger. The other diet had the same red-meat content plus a butyrate resistant starch formulation. Each person was on one diet for four weeks then after a four-week washout period, switched to the second diet for four weeks. Continue reading


The Science of Common Sense: More Evidence that AICR Recommendations Save Lives

Last week, yet another independent scientific study added to the robust evidence that following AICR’s 10 Recommendations for Cancer Prevention is powerfully protective against a great many diseases and conditions, not simply cancer alone.

This latest study found that childhood cancer survivors who follow more of our Recommendations are less likely to develop metabolic syndrome, a group of risk factors that raises the risk for heart disease and other health problems. We wrote about this new study in this week’s Cancer Research Update, our biweekly email newsletter on breaking cancer news.

Screen Shot 2014-08-07 at 11.38.01 AMPrevious independent studies have shown that our Recommendations protect against breast cancer and prostate cancer, reduce risk for cancer death, help people live longer, and improve cancer survivors’ physical and mental health. This latest study is a welcome addition to the ever-growing evidence that our advice maximizes your chances for leading a long and healthy life.

But in a way, it just makes sense. Continue reading


Study: Being Breastfed Links to Lower Inflammation

One of AICR’s Recommendations for Cancer Prevention is that mothers breastfeed their babies, with research showing that being breastfed can help reduce future cancer risk by helping the baby stay a healthy weight as an adult. Now a recent study suggests a new way in which breastfeeding may offer protection from cancer as well as other diseases, finding that young adults who were breastfed have a lower risk of chronic inflammation compared to those not breastfed.Mother And Baby Breast Feeding

There is a growing body of research suggesting inflammation increases the risk of many chronic diseases, including some cancers. Overweight and obesity, a risk factor for eight cancers, may produce a low level state of chronic inflammation.

AICR also recommends breastfeeding because research suggests it protects mothers against breast cancer. With August being National Breastfeeding Month, the study adds another potential benefit to the many recognized positives of breastfeeding.

Study authors used data from almost 7,000 participants who were part of national study on adolescent health. Twenty years ago, the participants were teenagers going to middle and high school.  They, and many of their parents were interviewed. Then in 2007-2008, when the participants were 24–32 years old, their levels of C-reactive protein (CRP) were measured from a blood sample. CRP is a marker of inflammation. Continue reading
