Does Eating Walnuts Reduce the Risk and Produce Smaller Prostate Cancers?

Friday, July 26th, 2013

logo1267406_mdA new study reported in Cancer Investigation concluded that eating a modest amount of walnuts can protect against prostate cancer. In studies researchers injected  tumors cells and noted they  start to grow in a large number of mice in 3 to 4 weeks. A previous study asked if a walnut-enriched diet would be associated with a reduced cancer formation in the injected mice and found positive results.In the prostate study the walnut enriched diet was utilized with prostate cell injected mice. Results showed that 3 ( 18 percent) of the walnut enriched diet injercted mice developed prostate cancer compared to 14 of 32 mice (44 percent) on the non-walnut controlled diet. In addition, the average size of the tumor in the mice with the walnut enriched diet was about 1/4 the size of the pro9state tumor as the non walnut eating control group. Researchers said ” We found the results to be stunning because there were so few tumors in animals consuming the walnuts and these tumors grew much more slowly than in the other animals.”     The diet for all mice was a typical animal diet except for the addition of the walnuts for the subjects. The walnuts added to the diet was equivalent to a human eating about 2 ounces, or two handfuls, daily. Conclusions by the researchers were “The data to date suggest that using walnuts on a regular basis in the diet may be beneficial to defer, prevent, or delay some types of cancer, including breast and prostate. “

Does Eating Nuts Reduce Your Risk of Dying From Cancer?

Wednesday, July 24th, 2013

logo1267406_mdA new study in BioMed Central’s journal BMC Medicine concluded that people who eat nuts, especially walnuts. more than three times a week have a reduced risk of dying from cancer or cardiovascular disease than non-nut eaters based upon data from a longitudinal study. Over 7,000 people age 55 to 90 were randomized to Mediterranean Diet /supplemented with extra virgin olive oil or nuts compared to a control group following a low fat diet. People who ate nuts tended to have a smaller waist and lower BMI, were more physically active, and les likely to smoke than those who rarely or never ate nuts. Nut eaters also were mote likely to have a better diet consisting of fruit, vegetables, and fish. The group eating nuts had fewer members with type 2 diabetes, or people on medications for hypertension. Overall-the nut eaters had a 39% lower mortality risk and walnut eaters had a 45% lower mortality than non-nut eaters.Also, people eating more than 3 servings a week (1 serving=28g) reduced their death rate by cardiovascular disease by 56% and cancer by 40%. The researchers said “Quite how nuts are able to prevent premature mortality is not entirely clear; nor why walnuts should be better for you than other nuts. Walnuts have particularly high content of alpha-linoleic acid and phytochemicals, especially in their skin both of which, along with fiber and minerals such as calcium, magnesium and potassium, may contribute to their healthy effect.”

A Diet Including Walnuts Reduces Breast Cancer Risk

Friday, September 16th, 2011


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.”
