A study published in Ginecología y Obstetricia de México (2006; 74(1):20–28) examined oxidative stress and dietary antioxidant intake in 48 women with endometriosis. The researchers found an inverse relationship between antioxidant intake and disease severity—women who consumed more antioxidants tended to have less severe endometriosis. The study also showed that women with endometriosis had poorer overall antioxidant status compared to healthy controls. Earlier research has linked endometriosis with chemical and environmental exposures, so these findings are consistent with the idea that higher antioxidant intake may help counter oxidative stress in women with endometriosis.
