A recent study has come up with the finding that consuming 28 grams of walnuts every day can reduce the chances of developing colon cancer by changing the gut bacteria.
According to one of the researchers of the University of Connecticut Health Centre in the US, Daniel Rosenberg, their findings showed that mice that consumed walnuts as 7-10% of their total calories developed fewer colon cancers. The study also showed that this effect was mostly found in the male species, which witnessed 2.3 times lesser tumours when they were given walnuts instead of a western diet.
According to Rosenberg, “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.”
In order to understand the importance of walnuts, the team of researchers conducted tests on the fecal samples of mice and examined the communities of bacteria present in their digestive tracts. The tests came up with the finding that consuming walnuts push the gut bacteria towards an ecology that was potentially protective against cancer. The researchers have said that in order to declare walnuts as cancer-preventing agents, more tests need to be conducted on humans also.
Walnuts are considered to be extremely beneficial for the health as they help in healthy ageing and also assist in enhancing the blood cholesterol levels. They contain nutritional compounds, such as, polyunsaturated fatty acids of all the commonly eaten tree nuts, Omega-3 to Omega-6 fatty acids and high levels of Vitamin E, which contains anti-cancer properties.
