Women whose diet contain big amounts of saturated fat can be at high risk for breast cancer, said a new study.

The study included data from 337,000 women ages 20 to 70 in 10 countries in Europe; the women were followed for an average of 11.5 years, Fox News reported.

Study researcher Sabina Sieri, of the National Cancer Institute in Milan recommended that calories from saturated fat should not exceed 10 percent of a person's daily diet.

The women in the study who ate the most saturated fat (about 47.5 grams per day) had about a 28 percent increased risk of breast cancer, compared with the women who ate the least saturated fat (about 15.4 grams per day).

The new study is published online April 9 in the Journal of the National Cancer Institute.
