Don’t be surprised if the next time you get your cholesterol tested, your doctor talks to you about a plant-based diet – vegetables, fruits, whole grains and legumes. New guidelines released yesterday for heart healthy living highlight that how you eat and move for heart health are what we know can also help you prevent cancer.
These new evidence-based guidelines for preventing cardiovascular disease (CVD) include lifestyle, drug and obesity management recommendations. They come from expert task forces convened by the American Heart Association and the American College of Cardiology.
For the first time, the recommendations for heart healthy eating focus on overall eating patterns, rather than just saturated fat or sodium. That’s good news, because examples they give, such as DASH and Mediterranean diets, are plant-based eating patterns. They also align with AICR’s recommendations for cancer prevention, including limiting sugary beverages, red meat and salt/sodium.
Here are key take-aways from the new heart health guidelines: Continue reading
If you choose to eat red and processed meats, just how often do you bite into that bologna sandwich or hot dog? What type of pork and beef do you eat? Is it low fat? What brand?
These are the kinds of answers that studies need in order to better understand how processed meat increases the risk of cancer, says Amanda Cross, speaking at our research conference today.
Cross, a scientist at Imperial College London, noted that the research clearly shows even small amounts of processed meat — and high consumption of red meats — increase risk of colorectal cancer. A study by Cross also suggests that processed meat increases risk of lung cancer; while diets high in red meat risk increase risk for esophagus and liver cancers.
Historically, the questionnaires used in studies of dietary intake only asked a couple questions on how much red and/or processed meats people typically ate. Now the science needs more.
When it comes to processed meat, researchers are looking closely at nitrate and nitrite. These chemicals, added to many processed meats, lead to potential carcinogens known as N-nitroso compounds. For burgers and other red meats, grilling and broiling them well-done can form heterocylic amines (HCAs) and polycyclic aromatic hyrdocarbons (PAHs), also potential carcinogens. Continue reading
Diets high in red and processed meats are a cause of colorectal cancer. Period.
That finding from our 2007 expert report was only strengthened in the 2010 Continuous Update Project Report on Colorectal Cancer, which reviewed evidence published since the 2007 report.
At this writing, more studies continue to be added to the CUP database; in 2017, the CUP expert panel will review the collected evidence once again and issue updated Recommendations for Cancer Prevention.
The existence of a link between red and processed meat and colorectal cancer is no longer surprising. But now researchers are asking the next questions –1. What is it, exactly, in red and processed meat that’s responsible for the increased risk, and 2. Is there anything we can do about it?
Amanda J. Cross, PhD, of Imperial College London, UK, will be presenting evidence tomorrow at our 2013 AICR Research Conference on Food, Nutrition, Physical Activity and Cancer. Continue reading
