Outcome Measures
Primary Outcomes (1)
Blood Levels of Total Estradiol Concentration
Blood levels were measured at the beginning and end of three weeks of one serving (5 ounces) of white wine daily and the beginning and end of three weeks of one serving of white grape juice (6 oz) daily, with a two-week washout period before each drinking period. Estimates for levels following three weeks adjusted for blood levels at the beginning of the drinking period.
3 Weeks
Secondary Outcomes (6)

WHITE WINE FOLLOWED BY WHITE GRAPE JUICE
EXPERIMENTALParticipants will be randomized into one of the study drinking sequence groups: white wine followed by white grape juice or white grape juice followed by white wine. The research study procedures include one screening visit to obtain informed consent, four study visits with blood draws, and ten weekly phone calls and online questionnaires over the ten weeks of the study. -3 weeks of daily white wine followed by 3 weeks of daily white grape juice
