Mediterranean Diet: Heart Healthy and Preventing Cancer

By Posted on Leave a comment on Mediterranean Diet: Heart Healthy and Preventing Cancer you’ve been trying to boost your heart health by eating a Mediterranean diet filled with olive oil, vegetables and nuts, and foregoing red and processed meat, a new report says you also may be lowering your risk for cancer and type 2 diabetes, all without losing weight.

A report of studies from PREDIMED, a large nutrition intervention trial, was published in the May issue of Advances in Nutrition. One study found that after almost 5 years, Mediterranean diet participants had 30% less cardiovascular disease than the control group. Another study found the Mediterranean diet groups had less type 2 diabetes, showed improvements in conditions of metabolic syndrome and had lower levels of markers for inflammation, all risk factors for cancer.

The Mediterranean diet, promoted as heart healthy, is rich in plant foods (such as vegetables, legumes, fruits and nuts), olive oil, moderate amounts of fish, yogurt, cheese, poultry and red wine, but little red and processed meats and sweets. In the PREDIMED study, researchers randomly assigned about 7500 participants to one of three groups: a Mediterranean diet (MeDiet) supplemented with olive oil, a MeDiet supplemented with nuts or they were instructed to follow a low fat diet. The PREDIMED study is a randomized, nutritional intervention trial conducted in Spain from 2003 to 2011. Read more… “Mediterranean Diet: Heart Healthy and Preventing Cancer”


    Study: Daily Dose of Nuts for Longer Life, Less Cancer Death

    Good things do come in small packages, according to the latest study looking at how a specific plant-based food – in this case, nuts – may affect how long we live.bigstock-Healthy-Food-alamond-cashews-A-34816445

    The new research, published in the New England Journal of Medicine, found that people who ate nuts at least five times per week had an 11 percent lower risk of dying from cancer than the nut avoiders. And those who included at least 1 ounce of nuts daily (a small handful) had the lowest rate of mortality from all causes, 20 percent less than those who ate none.

    One point to note about this finding is that it’s a correlation, meaning it links eating nuts to mortality, it doesn’t prove cause-and-effect. There are numerous factors that play a role in living longer, and the researchers attempted to statistically rule these other factors out,  including their weight, physical activity, high cholesterol, alcohol intake and other aspects of their diet.

      Mediterranean Diet, Heart Disease and Cancer Risk

      By Posted on 1 Comment on Mediterranean Diet, Heart Disease and Cancer Risk

      Yesterday, a major study published in the New England Journal of Medicine put a spotlight on how making dietary changes can have a major affect on health. The canstockphoto6734517study focused on the Mediterranean Diet and heart disease, finding that consuming a plant-based diet, along with plenty of nuts and healthy oils, linked to a reduced risk of stroke, cardiovascular death and heart attacks compared to those following a low-fat diet.

      Here’s the study.

      Briefly, researchers split almost 7,500 Spaniards at risk of heart disease – but showing no signs of any – into three dietary groups. One group consumed more extra-virgin olive oil, about four cups per week; a second group added about one ounce of nuts to their day; the third group was assigned to a low-fat diet. Along with nuts and healthy oils, the two Mediterranean-diet groups also ate more fish and legumes compared to the low-fat group.

      After five years, those following the two Mediterranean Diet patterns showed primarily a reduced risk of stroke.

      The Mediterranean Diet shares many qualities to the evidence-based diet shown to reduce cancer risk. Here, we asked AICR Nutrition Advisor Karen Collins, MS, RD, CDN, to talk about the diet and how it relates to cancer prevention.

      Q: Can you describe a Mediterranean Diet?
      A: It’s a plant-based diet that uses a large and abundant variety of vegetables and fruits. It makes vegetables and fruits the centerpiece of the meal, not just in the proportion but in the way they are seen as a way to enjoy and savor. The diet also has healthy fats and uses legumes abundantly. Meats, especially red meat but even poultry, are eaten in limited amounts.

      Q: What does the Mediterranean Diet share with AICR’s cancer-protective diet?
      A: They are both plant-based diets, with a wide variety of vegetables and beans, and they both limit red meats. The Mediterranean diet does generally involve some red wine but it’s not required – it’s not an essential part of the diet and for those who do drink, its only in moderation and generally only at meals.

      Q: What does the research show on the Mediterranean Diet and cancer risk? The research seems to be much clearer for heart disease.
      A: There are just more studies looking at heart disease and the Mediterranean Diet than with cancer. It’s not that the Mediterranean Diet doesn’t link to cancer prevention, its just not as well studied. So far, it looks like the Mediterranean diet can prevent certain cancers. Some research has suggested that following a Mediterranean Diet can reduce cancer mortality and incidence.

      Cancer develops over many years, which makes intervention-type trials a challenge. Research does link the Mediterranean diet with reductions in markers of inflammation, and combined with the abundance of antioxidant, cancer-fighting phytochemicals in the Mediterranean diet, this is an eating pattern that fits well in the overall model of a diet to lower cancer risk that we see in the New American Plate.

      Q: For people concerned with both heart health and cancer prevention, what can we take away from this?
      A: This study compared Mediterranean to a low-fat diet, which other studies have also done, and this shows that a singular focus in defining low-fat as being healthy is misplaced. It depends on what your eating when you reduce your fat.

      By eating a healthy diet and embracing the real principals of a varied and plant-based diet, its showing that it’s not just what you don’t eat, its what you do eat that counts. Eating healthy fats and a plant-based diet together can lower the risk of both heart disease and cancer.
