When you include the American Institute for Cancer Research in your estate plans, you make a major difference in the fight against cancer.

Corporate Champions who partner with the American Institute for Cancer Research stand at the forefront of the fight against cancer

The Continuous Update Project (CUP) is an ongoing program that analyzes global research on how diet, nutrition and physical activity affect cancer risk and survival.

A major milestone in cancer research, the Third Expert Report analyzes and synthesizes the evidence gathered in CUP reports and serves as a vital resource for anyone interested in preventing cancer.

Whether you are a healthcare provider, a researcher, or just someone who wants to learn more about cancer prevention, we’re here to help.

AICR has pushed research to new heights, and has helped thousands of communities better understand the intersection of lifestyle, nutrition, and cancer.

Read real-life accounts of how AICR is changing lives through cancer prevention and survivorship.

We bring a detailed policy framework to our advocacy efforts, and provide lawmakers with the scientific evidence they need to achieve our objectives.

AICR champions research that increases understanding of the relationship between nutrition, lifestyle, and cancer.

AICR’s resources can help you navigate questions about nutrition and lifestyle, and empower you to advocate for your health.

AICR is committed to putting what we know about cancer prevention into action. To help you live healthier, we’ve taken the latest research and made 10 Cancer Prevention Recommendations.

Alcohol, Processed Meats Increase Colorectal Cancer Risk, Updated Findings

AICR’s latest report on colorectal cancer found that processed meat and alcohol are a few of the factors linked to increased colorectal cancer risk, while whole grains lower the risk. Research published this month now confirms and reinforces these findings, as part of AICR’s ongoing review of the research.

The study was published in the Annals of Oncology.

Aside from skin cancers, colorectal cancer is the third most common cancer diagnosed in both men and women in the United States.

In 2011 AICR and the World Cancer Research Fund (WCRF) International published a report on colorectal cancer as part of the Continuous Update Project (CUP). WCRF/AICR–funded scientists at Imperial College London conducted the systematic review, which an independent CUP expert panel then analyzed and made judgments.

For this paper, Imperial scientists updated the 2011 CUP analysis, including articles published up to May 2015. The paper included 400 individual study estimates from 111 unique population groups.

Reduce Your Risk of Colorectal Cancer
See our infographic showing how diet, weight and physical activity link to colorectal cancer risk.

Foods associated with an increased risk of colorectal cancer included:

  • Red and processed meats: Risk increased 12% for each 100 grams/day increase of red and processed meat. A hot dog is about 50 grams.
  • Alcohol: Risk increased 7% for every 10 grams/day  of ethanol intake. A standard alcoholic drink contains 14 grams of ethanol.

Foods associated with an decreased risk of colorectal cancer included:

  • Whole grains: Risk decreased 17% for each 90 grams/day increase of whole grains.
  • Total dairy products: Higher intake of dairy products was associated with a decreased risk of colorectal and colon cancer, not rectal cancer independently. (This could be due to the smaller number of cases of rectal cancers.)

Lower risk of colorectal cancer was also seen with consuming higher amounts of vegetables and fish, but here the link was weaker and possibly driven by a single study. More research is needed.

There are several limitations to the findings, such as some studies may not have published their results on all food types or cancer subtypes. And the questionnaires may not have accurately reflected the foods participants eat.

AICR estimates that almost half – 47 percent — of US colorectal cancer cases are preventable each year through diet, physical activity and staying a healthy weight.
