For diet and cancer prevention, do we really know enough to act?

By Posted on 1 Comment on For diet and cancer prevention, do we really know enough to act?

We do know enough now to make eating choices that lower our risk of cancer. In fact, we know that for people with typical American diets, waiting for more information before making any changes is increasing their risk of cancer.

It’s true that research on diet to lower cancer risk is a hot area with many questions still to be answered. That’s why it’s important when making changes to make your decisions on guidelines based on the overall body of research. Trying to act on each new study that makes headlines can make you feel like you’ve got whiplash… not a wise approach.

This year’s AICR Research Conference featured the renowned Dr. Walter Willett of Harvard University presenting his view of what we know and don’t know on diet and cancer. Here’s my take, based on Dr. Willett’s presentation and others at the conference. Read more… “For diet and cancer prevention, do we really know enough to act?”

    Portion Size, Energy Density and Losing Weight – What Works

    By Posted on Leave a comment on Portion Size, Energy Density and Losing Weight – What Works

    This week, researchers opened our conference tackling one of the most important lifestyle issues related to cancer:  Exploring ways to effectively harness the power of healthy diet and exercise to help people get to and stay a healthy weight.

    That’s an urgent need, because after smoking, obesity is now the leading lifestyle risk factor for eleven cancers, including colorectal, pancreatic and postmenopausal breast.

    Dr. Barbara Rolls talked about our food environment, portion sizes and energy density and how those factors play a role in weight. She’s an international expert in how energy density (how many calories are in each bite compared to other foods) affects how many calories people eat. Results from her latest study suggest that several strategies using portion awareness, pre-portioned foods or just trying to eat less can all result in meaningful weight loss over a year’s time.

      SNPs, Activity, Vitamin D Research, Highlights from AICR Award Winners at ObesityWeek

      Congratulations to this year’s ObesityWeek Conference poster winners.

      The annual conference, held this year in New Orleans, focuses on the basic science, treatment, and prevention of obesity. It is an important topic because obesity links to several types of cancer, including post-menopausal breast, advanced prostate, and colorectal.

      Highlighted below are three of the winners of the AICR research poster competition, which was announced yesterday. The research focused on how genetics, physical activity, and nutrients influence cancer risk, treatment, and survival.

      Note: These poster findings have not been published and have not been subjected to the peer-reviewed process. Read more… “SNPs, Activity, Vitamin D Research, Highlights from AICR Award Winners at ObesityWeek”
