Walnuts Can Help Prevent Prostate Cancer
Walnuts are actually a rich plant source of omega-3s, the fatty acids also found inside cold water fish including salmon. Omega-3s are known to bring down the chance of a host of health issues from depression to heart disease. Walnuts are also loaded with gamma tocopherol (a form of vitamin E), phytochemicals known as polyphenols, as well as anti-oxidants. Now, for the very first time, scientists have revealed that these nutrient-rich nuts offer the capacity to help reduce the size in addition to growth associated with prostate cancer.
Scientists from the University of California-Davis just reported their discovery at the 239th National Meeting of the American Chemical Society (ACS), being held in San Francisco this week. “Walnuts should be part of a prostate-healthy diet,” Paul Davis, Ph.D., who headed the study, described in a statement to the media. “They should be part of a balanced diet that includes lots of fruits and vegetables.”
Nearly 190,000 males throughout the United States will be diagnosed with prostate cancer this year. According to the University of California-Davis scientists, analysis indicates that eating habits is without a doubt among the the most essential factors in influencing an individual’s chance with regard to developing prostate cancer. For example, you’ll find that there’s evidence that eating tomatoes in addition to drinking pomegranate juice might possibly decrease the risk of ever getting prostate cancer.
A short while ago, experts have discovered that walnuts can challenge cardiovascular disease by reducing levels of endothelin, a substance which increases inflammation inside blood vessels. Given that males with prostate cancer are known to possess increased levels of endothelin, the University of California-Davis experts reasoned that eating walnuts may possibly be efficient in blocking and/or healing prostate cancer.
Davis and his research crew conducted their particular study on laboratory mice which had already been genetically programmed to produce prostate cancer. One particular group of the animals consumed the equivalent of about 2.5 ounces of walnuts per day in a human eating plan (similar to in the region of 14 shelled nuts) for two months. A control number of mice did not receive any walnuts in their eating routine.
When the genetically caused prostate cancers evolved in the walnut-fed animals, their tumors ended up only about 50 percent as large as those associated with the control mice. What’s more, the actual malignancies within the walnut eating rodents also grew thirty percent slower.
So what exactly had been going on within the bodies of the mice that consumed walnuts? The investigators ascertained those mice experienced lower levels of insulin-like growth factor-1. That is definitely a crucial finding on the grounds that increased quantities of this protein are believed to boost the possibility of developing prostate cancer.
To further examine precisely why walnuts possessed the competence in order to battle prostate cancer, the researchers used gene chip technology to be able to track changes within gene levels in the animals’ tumors as well as in the livers of the mice. The outcome revealed consuming walnuts had a notably helpful impact upon both tumor and liver genes that have been shown to be involved in controlling the growth of malignant tumors.
