Recent study findings from Harvard School of Public Health suggest consuming trans fat could lead to infertility in women.
The study examined the dietary intake of 18,555 women with no history of infertility, who attempted to get pregnant between 1991 and 1999. Participants completed two food frequency questionnaires, reporting how often in the last year they had consumed each of the foods and beverages.
Researchers found that a two percent increase in energy intake from trans fat was associated with a 94 percent greater risk of infertility (defined as an inability to conceive after one year).
The association between trans fat intake and infertility remained significant even after adjusting for other influencing factors, such as body mass index and intake of alcohol.
The findings, published in the American Journal of Clinical Nutrition, found no association between intake of saturated, monounsaturated and polyunsaturated fats and infertility.
