Diet and medical nutrition therapy is a crucial part of PCOS management. The Academy of Nutrition and Dietetics’ Nutrition Care Manual includes evidence-based medical nutrition therapy guidelines for adolescents and young adults with PCOS which indicates that proper management of macronutrient intake and supplementation of a few micronutrients are helpful in reducing symptoms of PCOS such as bloating, male-pattern baldness, acne, irregular menstruation, hyperandrogenism and more. However, one size does not fit all and personalised nutrition guidance is recommended for all women. What supplements have been shown to regulate periods and improve fertility? Which nutrient reduces excess hair growth and acne? What does evidence tell us? To get answers to these questions and more, we talked to registered dietician Angela Grassi, a PCOS survivor herself who is an internationally known nutrition and health expert on PCOS, author of several books on PCOS and founder of PCOS Nutrition Center. PCOS patient advocate Lisa Rosenthal of RMACT helped guide the discussion from the patient panel.
