SOUTH KOREA—Consuming fish high in omega-3 fatty acids reduced the risk of breast cancer in both pre- and postmenopausal women in a study published in BMC Cancer.
Researchers studied 358 Korean women who suffered from breast cancer and 360 women who did not have the cancer from July 2007 to April 2008. Participants who ate more fish had a reduced risk of breast cancer in both pre- and postmenopausal women. In addition, this study found that those who consumed an average of 101 mg eicosapentaenoic acid (EPA) and 213 mg of docosahexaenoic acid (DHA) per day had the lowest risk of breast cancer compared to the group that consumed the least amount of omega-3 fatty acids.
