(WEBMD.COM) 28 February 2007:
Unexpected new data link low-fat dairy foods to infertility and high-fat dairy foods to better chances of getting pregnant.
The findings come from an eight-year study of 18,555 married female nurses by Harvard researcher Jorge E. Chavarro, MD, ScD, and colleagues, published in the February 28 online issue of Human Reproduction.
Chavarro tells WebMD he was surprised to find that:
Women who ate two or more weekly servings of low-fat dairy foods had an 85% higher risk of ovulation problems than women who ate one or fewer servings each week.
Women who ate one or more daily servings of high-fat dairy foods were 27% less likely to suffer ovulation problems than women who ate one or fewer servings each day.
Fertility expert Celia Dominguez, MD, assistant professor of gynecology and obstetrics at Emory University in Atlanta, notes that most of the women in the Harvard study were at near-normal weight. Since obesity is a major factor for women with ovulation, she warns overweight women against gorging on ice cream.
“Nobody needs to run off to eat Haagen-Dazs to get pregnant,” says Celia Dominguez, MD, assistant professor of gynecology and obstetrics at Emory University. ”But things like fat may not be as bad in a diet as perceived. We tell people balance is really important. I tell people to have some fat — no fat is no good — but balance is the key.”
