NEW YORK - Women trying to get pregnant could boost their chances by
adopting a "fertility diet" high in nuts and avocados while cutting down on
coffee and alcohol, according to U.S researchers.
Boston-based researchers found the majority of cases of infertility due to
ovulation disorders in otherwise healthy women could be prevented through diet
and lifestyle changes.
"The dietary and lifestyle choices women make as they try to get pregnant can
impact profoundly their fertility," Dr. Jorge E. Chavarro of Harvard School of
Public Health, who worked on the study, told Reuters Health.
The fertility diet is characterized by higher consumption of monounsaturated fat
rather than trans fats which is found in natural foods like nuts and avocados,
and olive oil.
Women should also opt for vegetable protein rather than animal protein, low-glycemic
carbohydrates like whole grains, moderate consumption of high-fat dairy,
multivitamins, and iron from plants and supplements, Chavarro's team reports.
Other changes women can make to their lifestyle promote fertility include
cutting back on coffee and alcohol, increased physically activity, and staying
away from cigarettes.
The research was based on 8 years of Chavarro and colleagues tracking the diet
and lifestyle patterns of 17,544 women as they tried to get pregnant or became
pregnant. None of them had a history of infertility.
According to the team, greater adherence to the fertility diet pattern was
associated with a lower risk of infertility due to ovulation disturbances and,
to a lesser extent, of infertility due to other causes.
Women with the highest fertility diet score, compared with those with the
lowest, had a 66-percent lower risk of infertility due to ovulation problems and
a 27-percent lower risk of infertility due to other causes, Chavarro and
colleagues report in the journal Obstetrics and Gynecology.
The combination of five or more low-risk lifestyle factors, including weight
control, physical activity and diet, was associated with a 69-percent lower risk
of ovulation-related infertility.
The researchers also found, consistent with earlier reports, that increased body
weight raises the risk of infertility due to ovulation disorders.
"Women trying to become pregnant could consider following these lifestyle
practices because they are consistent with an overall healthy lifestyle and may
also help them become pregnant," the researchers said.
