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: How Your Colleagues, Family and Friends May Impact Weight Loss

With all the weight loss support groups out there, it’s no surprise that having support can make a difference when it comes to eating healthier and exercising. A new study now suggests that coworkers, friends and family can undermine weight loss or increase it over two years, depending upon their support.Lowsection of two businesspeople walking up stairs with bags in

The study is important for cancer prevention – along with overall health – because overweight and obesity increases risk of eight cancers, including colorectal and postmenopausal breast.

Published in Obesity, the study included 633 high-school employees who were participating in a weight gain prevention study. About a third of the participants were overweight and another quarter were obese.

At the start, participants were weighed and then answered questions about how supportive or unsupportive their friends, family and colleagues were about their diet and exercise behaviors. Continue reading
