BACKGROUND/OBJECTIVES: Little is known about nutritional factors that influence circulating concentrations of @entity134 hormones, which are consistently associated with risk of @entity0 for postmenopausal @entity1 . We aimed to investigate the association between consumption of animal products and the plasma concentrations of @entity134 hormones and @entity443 ( @entity443 ). SUBJECTS/METHODS: Cross-sectional analysis was conducted on plasma from 766 naturally postmenopausal @entity1 . We measured plasma concentrations of @entity134 hormones and @entity443 , and estimated dietary intakes using a 121-item food frequency questionnaire. Log-transformed values of hormone concentrations were regressed on quartiles of intake of meat and dairy products among food items, and fats, proteins and @entity165 among nutrient intake. RESULTS: Total red and fresh red meat consumption was negatively associated with @entity443 levels (P for trend=0.04 and <0.01, respectively). Mean @entity443 concentrations were approximately 8% and 13% lower for @entity1 in the highest quartile compared with the lowest quartile of total red and fresh red meat consumption, respectively. Positive associations were observed between dairy product consumption and total and free @entity53 concentrations (P for trend=0.02 and 0.03, respectively). Mean concentrations of total and free @entity53 were 15 and 14% higher for @entity1 in the highest quartile of dairy product consumption than for those in the lowest quartile, respectively. No associations were observed with consumption of processed meat, @entity1573 , fish, eggs, @entity165 , fats or protein. CONCLUSIONS: Our study suggests that greater consumption of total red and fresh red meat and dairy products might influence circulating concentrations of @entity443 and @entity53 , respectively. Confirmation and further investigation is required.
