Glycemic load, dietary fiber, and added sugar and fecundability in a North American preconception cohort

To evaluate prospectively the association between glycemic load (GL), dietary fiber (DF), and added sugars and fecundability. Total GL reflects quantity and quality of carbohydrates in the diet; DF and added sugars are related to total GL. Diets with high GL have been linked with adverse health outcomes, including polycystic ovary syndrome and diabetes. Sugar-sweetened beverages, a high-GL food, have been associated with reduced fertility in many studies.1 Studies of the association between DF intake and reproductive function have been mixed, with one study showing a positive association between high fiber intake and anovulation and another reporting little association between fiber intake and ovulatory infertility.
