Like it or not, have about 28 grams of walnut a day and keep colon cancer at bay.

Researchers have found that walnuts may change gut bacteria in a way that suppresses colon cancer. “Our results show for the first time that walnut consumption may reduce colon tumour development,” principal investigator Daniel Rosenberg of University of Connecticut Health Centre in the US was quoted as saying by UConn Today.

“There is accumulating evidence that eating walnuts may offer a variety of benefits related to health issues like cancer. This study shows that walnuts may also act as a probiotic to make the colon healthy, which in turn offers protection against colon tumours,” Rosenberg noted.

The findings were reported in the journal Cancer Prevention Research.

Walnuts pack the most significant anti-cancer punch against colon cancer, the third most common cancer in the world. Walnuts are said to have several nutritional benefits. They have the most polyunsaturated fatty acids of all the commonly eaten tree nuts, as well as the highest ratio of omega-3 to omega-6 fatty acids and high levels of a form of Vitamin E with anti-cancer properties.

An American Institute of Cancer Research newsletter had also reported that eating walnuts may help to prevent breast and possibly prostate cancers or slow their progression. Studies on prostate and breast cancer have established that something in walnuts, most likely a combination of substances, reduces the initiation of tumors and slows the growth of cancer cells.

Last month, another study conducted by South Korean researchers revealed that the lipid extracts from walnuts may affect the self-renewal capacity of cancer stem cells that lead to colon cancer. The research team, headed by Prof Yuri Kim of the Department of Nutritional Science and Food Management at Ewha Woman’s University, studied the effects of walnut lipid extracts on colon cancer cells. This was the first study conducted by California Walnut Commission (CWC) in South Korea. Its CEO Dennis A Balint said that CWC will continue to invest in cancer research to establish stronger evidence about the benefits of walnuts’ benefits
