American scientists at the University of California have reiterated the wonderful advantages of eating walnuts in a new study.
The first group did not consume walnuts, the second group received walnuts, and the third one was fed with walnut oil. The experiment showed that the development of the tumor and malignant cells significantly slowed among the rodents in the second and the third groups.
Raw walnuts contain phytonutrients, a natural substance which restrains the growth of cancer cells. The scientists attribute the success of the tests to this, and further reveal that only two handfuls of walnuts daily is enough to reduce the chances of both prostate and breast cancer by about 50 percent.
Experts however advise caution in its intake as walnuts are a high calorie product. For example, just 2.6 ounces of walnuts is about 482 calories, which may amount to an excess of reserved fat in some people.
