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
Heart disease, cancer and diabetes together cause about 1.3 million deaths each year in the US. A key lifestyle strategy for preventing and/or managing these diseases is getting to and staying a healthy weight. But losing weight – and keeping it off – is hard, and though many people are able to improve their weight, many more struggle to be successful.
Last month an editorial in Open Heart made a strong case that it’s time to stop counting calories and instead, focus on WHAT you eat.
A healthy diet, with plenty of vegetables and healthy fats, has both quick results for better health and long-term benefits for weight, argue the authors. They cite studies looking at how shifting to a healthy diet can lead to immediate positive effect on cardiovascular disease and diabetes. One of their examples is from the PREDIMED study where participants who ate a Mediterranean, plant-based diet with nuts and olive oil, but not calorie restriction, showed lower rates of type 2 diabetes and improved metabolic health.
We also know – from AICR’s evidence-based recommendations – that eating a diet built on plant foods like vegetables, legumes, whole grains and nuts, can reduce risk for many cancers, including colorectal and endometrial.
But survey after survey finds that the vast majority of adults and kids in our country are not eating enough fruits and vegetables. Continue reading
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.
