A Diet Including Walnuts Reduces Breast Cancer Risk

A new research study published in Nutrition and Cancer concluded that the risk of breast cancer was significantly reduced in mice when their regular diet included walnuts. Using a mouse model one group was given a typical diet with the equivalent of 2 ounces of walnuts a day (for humans) to mothers from conception to weaning and then to the offspring thereafter. The other group received a typical diet without the walnuts. During the study period those whose diet included walnuts developed breast cancer at less than half the rate of those on the typical diet only. In addition, the numbers of tumors and sizes were significantly smaller.
The researchers said “These reductions are particularly important when you consider that the mice were genetically programed to develop cancer at a high rate”. “We were able to reduce the risk for cancer even in the presence of a preexisting genetic mutation.”
