A new study that adds to the evidence on diet and colorectal cancer suggests that vegetarians have a lower risk of this cancer than non-vegetarians, with fish-eaters — pescovegetarians — showing the lowest risk of the non-meat eating groups.
The study was published yesterday in JAMA Internal Medicine and it will be a part of AICR/WCRF’s ongoing collection of the worldwide research. The latest AICR/WCRF report on colorectal cancer concluded that diets high in red meat increase the risk of colorectal cancer.
The study collected the eating and other lifestyle habits of almost 78,000 Seventh-Day Adventists, a group that traditionally advocates vegetarian and healthy eating. Researchers categorized the group into those who ate meat regularly and four vegetarian patterns: 1) ate fish regularly; 2) ate milk and eggs regularly 3) ate small amounts of meats and fish; and 4) ate no meats, dairy or any animal food (vegans).
Overall, vegetarians had lower BMI, ate less fat, red meat, and processed meat, and ate more fiber.
Slightly more than half the study population was categorized as vegetarians. Over 7 years, there were 490 cases of colorectal cancer. Continue reading
Over the past three decades there’s been a slight but steady decline in colorectal cancer incidence here in the US, thanks in large part to increased screening. Now a study out this week showing that rates of this cancer are increasing among young people — below the typical screening age — highlights the importance of people of all ages adopting healthy behaviors that can halve the risk of colorectal cancer.
The study – published in JAMA Surgery – found that among 20- to 34-year-olds, the data indicates incidence of colon and rectal cancer will increase by 90% and 124%, respectively, by 2030. Among the 35 to 49 year olds, rates are estimated to increase by 28% and 46%, respectively.
This large study confirms previous research on incidence trends, and it points to a growing public health problem, the authors note. Lifestyle and behavioral factors such as obesity may be a possible cause.
AICR estimates that half of all colorectal cancer cases are preventable if people were to eat healthier diets, move more and stay lean.
Following at least two healthy behaviors that are key AICR Recommendations, such as eating a healthy diet and being active, lowers the risk of colorectal cancer to some degree, with the more you follow the lower the risk, suggests a new study that highlights the importance of practicing multiple healthy behaviors.
Published in BMC Medicine, the study joins a growing body of independent research that investigates how AICR Recommendations for Cancer Prevention link to reduced risk of specific cancers, survivors, and mortality. Here are some of those other studies.
This latest study was conducted among 350,000 Europeans ages 25 to 70. They are part of the large European Prospective Investigation into Cancer and Nutrition (EPIC), which spans 10 countries. When people joined EPIC they gave information about their diet, smoking, activity and other lifestyle habits. Continue reading
