At the same time that global warming is making news, a study suggests that eating more fruits, vegetables and nuts and less meat and alcohol — with fewer calories – can reduce greenhouse gas emission by almost 20 percent, compared to the average diet. Many of the dietary patterns identified as environmentally healthy align with AICR’s recommendations for cancer prevention.
The study, published in the American Journal of Clinical Nutrition, is one of the first that takes into account foods nutrition along with its environmental impact.
Last month, the Food and Agriculture Organization (FAO) released estimates showing that greenhouse gas emissions from agriculture was on the rise.
This study used greenhouse gas emissions related to farming and production as a measure of a food’s environmental impact. That includes methane produced by cows and fertilizers applied to crops.
For the study, researchers analyzed the diets of almost 2,000 French adults who were part of a nationally representative diet survey. Researchers categorized the foods into groups, calculating how its nutrients and calories contributed to a person’s overall daily diet. They also looked at how much the foods cost. Continue reading
Today’s issue of Cancer Research Update highlights a new analysis of the research suggesting that obesity links to poorer survival for women diagnosed with breast cancer. The research adds to a complex and evolving field of research on lifestyle and survivorship.
The findings in this paper add to the body of knowledge, but they are not proof that weight loss in overweight or obese women will improve survival, says Anne McTiernan, MD, PhD, one of the authors of the new paper and a Continuous Update Project expert panelist.
Here, Dr. McTiernan — the Director of the Prevention Center at the Fred Hutchinson Cancer Research Center — talks about the study and what it means for breast cancer survivors.
Q: This study is the first to look at BMI pre- and post-diagnosis, and 12 months following diagnosis. Why was it important to look at these three points?
A: While it’s interesting to know what effect BMI before diagnosis has, women want to know what they can do now, for their future. So it’s important to look at the post-diagnosis period. Continue reading
A new study involving the emerging research on lifestyle’s role in breast cancer survivorship suggests that obesity — both before and after a breast cancer diagnosis — is associated with earlier death from cancer or other causes, compared to women at a healthy weight.
The paper was published yesterday in the Annals of Oncology. It adds to a complex and relatively new area of research: what survivors can do to lengthen life and stay healthy.
In a major report on breast cancer survivorship due this Fall, World Cancer Research Fund International’s Continuous Update Project (CUP) expert panel will consider this latest paper as it works to shape official recommendations for cancer survivors. AICR is the US member of World Cancer Research Fund International.
The Annals of Oncology paper was written by a team of scientists involved in the CUP, including Anne McTiernan, MD, PhD, Director of the Prevention Center at the Fred Hutchinson Cancer Research Center. The paper found that “increased body size is significantly related to survival after a diagnosis of breast cancer…” said Dr. McTiernan. But the findings are not proof, she says, more research is needed. Continue reading
