Polycystic ovary syndrome (PCOS), one of the most common endocrine disorders in women of reproductive age, affects 1.4 million women in Canada alone. Women with PCOS have excessive body weight, increased risk of type II diabetes, irregular menstrual cycles, and abnormal ovarian function which affects their ability to become pregnant. Medical professionals recommend lifestyle modifications including diet and exercise to manage PCOS symptoms; however, there is no current consensus regarding the optimal diet for women with PCOS.
Building on research completed within the first Pulse Science Cluster, this study further examines using a pulse-based diet as a nutrition intervention for the PCOS population. For 16 weeks, study participants consumed two servings of pulses daily and completed 45 minutes of aerobic exercise 5 times per week, and the researchers examined reproductive measures (sex hormone levels; antral follicle count), blood lipids (cholesterol), insulin, glucose (blood sugar levels), body composition (body mass, muscle mass, and bone mass), and liver fat levels. The researchers found the pulse-based diet led to improvements in reproductive measurements (decreased ovarian follicle counts) and lowered the cholesterol ratio (total cholesterol/HDL cholesterol). An evidence-based cookbook with 50+ healthy, easy, and affordable recipes for entrees, soups, and salads has been developed for PCOS patients, clinicians and researchers.
