BACKGROUND: Longitudinal studies suggest that diets encouraging a higher intake of fruits and vegetables and a lower intake of red meat are associated with a lower risk of laparoscopically confirmed endometriosis. However, no studies have e…

BACKGROUND: Multiple in vivo and in vitro studies have demonstrated that 25-OH vitamin D has a significant positive effect on ovarian reserve in women; however, findings from population-based studies have been inconsistent. OBJECTIVES: Thi…

BACKGROUND: Tissue repair and regeneration in the gastrointestinal system are crucial for maintaining homeostasis, with the process relying on intricate cellular interactions and affected by micro- and macro-nutrients. Iron, essential for v…

A high incidence of obesity and surplus body fat has been observed in wealthy countries for many decades. It is generally recognized that these excesses contribute to serious disease states, including type 2 diabetes and cardiovascular dise…

BACKGROUND: Maternal prenatal smoking is known to alter offspring DNA methylation (DNAm). However, there are no effective interventions to mitigate smoking-induced DNAm alteration. OBJECTIVES: This study investigated whether 1-carbon nutri…

BACKGROUND: The etiology of endometriosis is not well understood. Limited evidence suggests that dietary factors influence risk, but prospective data related to carbohydrate, fiber, and gluten consumption are scarce. Despite this, recommend…

BACKGROUND: Overweight and obesity among women have been associated with lower success of assisted reproduction technologies (ARTs). However, the relation of adolescent body weight and adult weight change to ART outcomes is not well underst…

BACKGROUND: Soy infant formula contains isoflavones, which are able to bind to and activate estrogen receptor (ER) pathways. The mammary gland is sensitive to estrogens, raising concern that the use of soy formulas may promote premature dev…

BACKGROUND: Dairy food intake has been associated with infertility; however, little is known with regard to associations with reproductive hormones or anovulation. OBJECTIVE: We investigated whether intakes of dairy foods and specific nutr…

BACKGROUND: Evidence is growing that the equilibrium between reactive oxygen species and antioxidants plays a vital role in women's reproductive health. OBJECTIVE: The objective of this study was to evaluate variations in serum antioxidant…

BACKGROUND: Phytoestrogens have been associated with subtle hormonal changes, but their effects on endometriosis are largely unknown. OBJECTIVE: We assessed the association between urinary concentrations of phytoestrogens and incident endo…

An increasing recognition has emerged of the complexities of the global health agenda—specifically, the collision of infections and noncommunicable diseases and the dual burden of over- and undernutrition. Of particular practical concern ar…

Equol, first isolated from equine urine in 1932 and identified 50 years later in human urine as a metabolite of the soy isoflavones, daidzin and daidzein, is produced by intestinal bacteria in some, but not all, adults. This observation led…
