Fish Oil Linked to Lower Breast Cancer Risk
Postmenopausal women between the ages of 50 and 76 who took fish oil were 32% less likely to develop certain types of breast cancer than women who didn’t, the study found.
The researchers looked at 14 other popular supplements (including gingko biloba, black cohosh, soy, and St. John’s wort), but only fish oil—which contains concentrated amounts of the omega-3 fatty acids found in salmon, tuna, and other fish—had any connection to breast cancer risk.
Despite their findings, the researchers say it’s too soon to recommend that women start taking fish oil to stave off breast cancer.
“People should try to achieve nutrients through a healthy diet, so eating fish is a better recommendation than fish oil,” says the lead author of the study, Emily White, PhD, an epidemiologist at the Fred Hutchinson Cancer Research Center, in Seattle. “We think that fish oil is promising in terms of disease prevention, but it’s not proven.”
