Among the population as a whole, research shows a strong link between being obese and increased risk of pancreatic cancer. Now a large new analysis suggests that obesity increases the risk of African Americans dying from pancreatic cancer, a cancer that affects African Americans more than any other racial group.
The study was published in Cancer Epidemiology Biomarkers and Prevention.
African Americans are diagnosed with and die from pancreatic cancer more than any other racial group, according to the National Cancer Institute. Previous research focusing on obesity, African Americans and pancreatic cancer included only a few study that gave conflicting findings.
For this analysis researchers pooled data from seven studies, including almost 240,000 African Americans. The studies all had used self-reported information to calculate BMI, a standard measure of body fat.
You may have noticed that things look a little different around here today.
We’ve given the AICR logo and brand identity a fresh coat of paint, and we’ve tweaked our homepage to make it easier for you to find everything we have to offer.
But what I and everyone here at AICR is most excited about is the new mini-site we’re launching today – a new initiative to turn the evidence-based guidance we’ve been giving Americans for decades into a bold new public awareness campaign – one that reaches the heart, as well as the head.
At this mini-site, CANcer PREVENTion: Together We Can, we’ve created new tools, quizzes and interactive content to help you start living for lower cancer risk today.
I hope you take a moment to poke around the site and share it with friends. It’s our attempt to distill massive amounts of research into a format that’s inviting, engaging and easy-to-use.
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.
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
