For years, we’ve heard a lot about the heart health benefits of the Mediterranean Diet. Now an analysis from a randomized trial suggests this diet, supplemented with extra-virgin olive oil and nuts, may help lower risk of breast cancer.
The analysis, published in the Journal of the American Medical Association, is from the PREDIMED trial – a 6 year study that includes data from over 4000 women, 60-80 years old and at high risk for cardiovascular disease. The women had been assigned to follow one of three diets, a Mediterranean diet where they received extra virgin olive oil, a Mediterranean diet with provided mixed nuts, or they were advised to follow a low fat diet. The women had quarterly sessions with a dietitian to assess how well they were following the diet.
At the end of the study, the women following the Mediterranean diet with olive oil showed a 62% lower risk of malignant breast cancer than the control, low fat diet group. When researchers put the olive oil and nuts groups together, there was a 51% relative risk reduction compared to the control group. Continue reading
Research clearly shows that alcohol increases risk for breast cancer overall. Now, a study published this week in the International Journal of Cancer finds that drinking alcohol increases risk for nearly all breast tumor types, especially when women start drinking as young adults. The risk is modest, but it shows one way women can take steps to lower their risk.
Using data from the European Investigation into Nutrition and Cancer (EPIC) study, researchers included 335,000 women from ten European countries and of those,11,576 participants had breast cancer diagnoses after an average of 11 years follow-up. Data on participants included BMI, waist to hip ratio, smoking status, physical activity, education level and diet information. The authors calculated how much alcohol women drank over their life, based on surveys the women filled out on what they drank in their 20s and beyond. About 15% of the women drank more than one alcoholic drink daily. Continue reading
Low alcohol consumption and a plant-based diet, part of AICR’s Recommendations for Cancer Prevention, are associated with reducing the risk of colorectal and other obesity-related cancers, finds a new study, adding to a growing body of independent research on how following AICR’s recommendations links to lower cancer risk, longer survival, and improved overall health.
This latest study was published in Cancer Causes & Control. You can read more about the other studies investigating AICR recommendations here.
The Cancer Causes & Control study included almost 3,000 cancer-free adults who had no history of cancer. Participants were part of the ongoing Framingham Heart Study. Back in 1991, everyone filled out a questionnaire about how much they weighed, what they ate and their activity habits.
After almost 12 years, 480 of the participants had developed an obesity-related cancer, such as colorectal or breast.
Study researchers then scored how much participants met seven of AICR’s recommendations, giving them zero, half point or one point. The scoring included Continue reading
