    INC Press Release - Nut consumption may reduce incidence of breast and colon cancer

    Eating 2 or 3 servings per week (28-57g) of nuts can reduce the risk of several types of cancer.

    February 2016- Adding nuts to your diet is associated to a reduction in the risk of cancer. This is the main conclusion of multiple studies that have shown that eating 2 or 3 servings per week (28-57 g) of nuts, such as peanuts, walnuts or almonds, is associated to a reduction in the risk of some types of cancer (breast, colon, pancreatic and lung cancer).

    A study by Dr. Soriano-Hernandez and his team at the University of Colima (México) has concluded that frequent consumption of peanuts, walnuts or almonds is associated to a reduced risk of breast cancer by a factor of 2 or 3. Researchers analysed 97 patients with breast cancer and 104 control subjects who did not have the pathology.[1] Another study from Brigham and Women's Hospital, Harvard Medical School (USA) showed that eating 2 servings of nuts per week during adolescence is associated to a 36% lower risk of breast cancer compared to women consuming less than 1 serving per month[2].

    Different studies have shown that nut consumption can reduce the incidence of colon cancer as well. In 2004, the European Prospective Investigation into Cancer and Nutrition showed a reduced incidence of colon cancer in women who ate an average of 16 g of nuts and seeds daily. This study revealed that women who consumed more than 6.2 g per day of nuts and seeds was associated to a 31% lower risk of colon cancer[3]. Earlier this year, a team of researchers from Brigham and Women's Hospital, Harvard Medical School (USA) found that women who consumed nuts twice or more per week (approx. 56 g per week) had a 13% lower risk of colorectal cancer compared with women who rarely consumed nuts.[4]

    Furthermore, eating just 2 servings (28 g) is associated with a 32% lower risk of pancreatic cancer among women[5] and researchers from the DCCPS National Cancer Institute (Maryland, United States) have reported that nut consumption was statistically associated with a reduced risk of lung cancer. [6]

    The conclusion is that eating nuts is not only associated with a lower risk of cancer but also a reduced risk of death from cancer. These are the results of the PREDIMED study (PREvención con DIeta MEDiterránea), which indicated last year that participants who habitually had 3 servings (57 g) per week of nuts enjoyed a 40% reduction in deaths from cancer .[7]
