Nuts are in fashion, nutritionally speaking, especially for heart health. Now, a new study finds that if you eat a handful of nuts several times a week that may help lower your risk of cancer.
Study results on nut consumption and cancer prevention have been inconsistent. In this systematic review and meta-analysis published in Nutrition Reviews, the researchers evaluated 36 studies – both large population studies and clinical trials – examining the relationship between eating nuts and risk of cancer or type 2 diabetes.
By comparing people who ate the most nuts (typically at least 4-5 times per week) to those who ate the least (typically 1 time per week or less), the researchers found that the high nut eaters had 15 percent lower risk of cancer overall. In specific cancers, they found lower risk for colorectal, endometrial and pancreatic cancer. They did not find any significant difference for risk of type 2 diabetes.

If 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”
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.
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.
