Study: Eating Vegetarian (+Fish) Lowers Colorectal Cancer Risk

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


How New Dietary Guidelines Report Align with Cancer-Protective Diet

New dietary guidelines may soon include increased emphasis on dietary patterns, fruits and vegetables while limiting added sugars, red meat and sugary beverages, if the recommendations released today from the Advisory Committee’s report are accepted.

The report is comprehensive — 571-pages long — and the American Institute for Cancer Research is cited throughout. You can read the highlights of how the report findings correspond with a cancer-protective diet in our press release.

Overall, the report aligns closely with AICR’s evidence-based Recommendations for Cancer Prevention, which focus on a plant-based diet. In the executive summary of the report:

The overall body of evidence examined by the 2015 DGAC identifies that a healthy dietary pattern is higher in vegetables, fruits, whole grains, low- or non-fat dairy, seafood, legumes, and nuts; moderate in alcohol (among adults); lower in red and processed meat; and low in sugar sweetened foods and drinks and refined grains.

The expert committee also reports on the importance of focusing on eating patterns and foods, as opposed to single nutrients or compounds. As the report states:

These dietary patterns can be achieved in many ways and should be tailored to the individual’s biological and medical needs as well as socio-cultural preferences.

Here at AICR, we have the New American Plate, a flexible way of eating that centers around plant foods. Two-thirds or more of your plate should have fruits, vegetables, whole grains or other plant foods; the rest of your plate has milk, meat, fish or other animal foods. The goal is to consume high amounts of healthful plant foods both for cancer prevention and health, but also to get to/stay a healthy weight.

Yesterday, we wrote about how the report is dropping the longstanding recommendation to limit dietary cholesterol. Here’s how that fits into a cancer-protective diet.

Next comes a public comment period, where there’s also a date for commenting in person. You can submit your comments through their site. And you can also tell us your thoughts about the report in the comments on the blog.

The 2015 Dietary Guidelines Advisory Committee report is the scientific foundation for the upcoming Dietary Guidelines for Americans. Released every 5 years, the guidelines become the basis for food, school and nutrition policy.


Coffee One Way to Cut Endometrial Cancer Risk

Coffee lovers are likely enjoying a new study finding that coffee lowers risk for endometrial cancer, with the drink being almost the lone dietary factor linked to risk. The study was a large one and it’s coffee findings are similar to those of AICR’s report released last year.22007913_s

That’s certainly good news for coffee lovers, but whether you do or don’t enjoy coffee, the beverage is only one of several ways you can protect yourself against endometrial cancer.

The study, published in this month’s Cancer Epidemiology, Biomarkers & Prevention, looked at 84 foods and/or nutrients related to endometrial cancer risk. Study researchers first investigated the link among about 300,000 women participants of the European Prospective Investigation into Cancer and Nutrition (EPIC). Women had filled out questionnaires about what they ate and other lifestyle habits, and then they were tracked for endometrial diagnosis or death. This led to 10 factors linked to either increased or decreased risk, including coffee, total fat, butter, and cheese.

Then the researchers looked at how these factors linked to 155,000 women who were in two US studies, the Nurses’ Health Studies I and II. These women had also had answered questions about diet and other factors. Continue reading
