A 2007 study published in The American Journal of Clinical Nutrition identified an increased risk for infertility in women who consumed more trans fats compared to polyunsaturated and monounsaturated. In fact, women who consumed more trans fats than monounsaturated fats had double the risk of ovulatory infertility. Trans fats can be found in foods like potato chips, fast food, and prepackaged sweets like cakes and pies.
Nancy Weiss, a fertility coach with Grateful Life Wellness, told POPSUGAR that women should "try to opt for whole foods that are minimally processed. It's OK to indulge, but be aware of the potential hidden amounts of trans fats in food."
