The British Journal of Cancer published a new study from Harvard University that found that eating one nut a day twice a week can reduce the risk of the most deadly pancreatic cancer by a third. The new study does not distinguish between the types of nuts, and emphasizes that it is more important to eat nuts than to eat only one type of nut.
A number of early studies have shown that nuts have multiple anti-cancer properties as part of a healthy diet, but the results are still inconclusive. To investigate the specific effects of eating nuts on the incidence of pancreatic cancer, researchers at the Harvard School of Public Health reviewed the data on the US Nurses Health Research project. The researchers recruited 75,000 women who participated in the study and analyzed the incidence of pancreatic cancer in these women. Later, the cancer patients were investigated for nutrients and compared with the corresponding data of healthy participants without pancreatic cancer.
It was found that women who ate nuts 2 or more times a week, or 1 ounce each (about 28 grams, equivalent to one), can reduce the risk of pancreatic cancer by 35% compared with women who never eat nuts. After the researchers ruled out factors such as obesity and diabetes, the association between eating nuts and lower incidence of pancreatic cancer remained.
