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.

About one of every two American adults has or is at risk of having diabetes, with approximately a third of those with diabetes unaware they have it, finds a new study that offers important insights into cancer risk. People with type 2 diabetes are at increased risk for many of the most common cancers, including liver, colon and postmenopausal breast.
The study was published in The Journal of the American Medical Association.
Study authors used various national health survey data conducted periodically from 1988 to 2012. Participants had answered health questions and gone in for an exam, where they gave blood samples and had their weight and height measured. Anyone who reported a previous diagnosis of diabetes went into the diabetes category. Those with various measures of blood sugar levels over a set amount were categorized as having either undiagnosed or pre-diabetes.
Using one set of measures with the most current available data (2011-12), 14 percent of adults have diabetes. Yet about a third of those with signs of the disease have not been diagnosed. Another set of blood sugar measures puts the figure at 12 percent of adults having diabetes with a quarter of these people having the disease undiagnosed.
And another third of adults – slightly more – have prediabetes, a condition that shares many risk factors with common cancers.
If you’re a reader of health news, there’s a good chance you’ve heard about the research looking at how office walking breaks can help your health. Now comes a small study suggesting that those breaks may also improve kids’ long-term metabolic health, which may lower their risk for adult cancers decades later.
The study found that children who break up their sitting with three minutes of walking every half hour had lower levels of blood glucose and insulin, compared to when they remained seated for three hours. It was published in the Journal of Clinical Endocrinology and Metabolism. High blood glucose and insulin are risk factors for metabolic syndrome, a cluster of conditions that also links to increased cancer risk among adults.
According to government data, more than one third of children and teens are overweight or obese. Kids who are overweight are more likely to be overweight adults, and excess body fat among adults is a cause of ten cancers.
