Pesticides in produce linked with reduced fertility in women

Eating fruits and vegetables with high amounts of pesticide residue — such as strawberries, spinach, peppers, or grapes — may reduce women’s chances of conceiving and bearing children, according to a new study from Harvard T.H. Chan School of Public Health.

The study, published Oct. 30, 2017 in JAMA Internal Medicine, looked at 325 women undergoing infertility treatment as part of the Environment and Reproductive Health (EARTH) study. Researchers compared information about the women’s diet, drawn from questionnaires they filled out, with U.S. government data on average pesticide residues on fresh fruits and vegetables, in order to estimate the women’s diet-related exposure to pesticides.

The study found that women who ate more than two servings of high-pesticide fruits or vegetables each day, compared with women who ate an average of one each day, were 18 percent less likely to become pregnant and 26 percent less likely to have a live birth than women with the lowest exposure.

Jorge Chavarro, associate professor of nutrition and epidemiology at Harvard Chan School and senior author of the study, said that women trying to conceive may want to limit their intake of high-pesticide fruits and vegetables or eat organic versions, or choose low-pesticide produce such as avocados, onions, or oranges. “I am now more willing to buy organic apples than I was a few months ago,” he told TIME.

Lead author of the study was Yu-Han Chiu, a doctoral student at Harvard Chan School.
