DASH diet can be recommended for women having PCOS to improve insulin resistance and re establish hormonal balance. It also helps in addressing truncal obesity in PCOS women.

     One study  corroborates this finding as it concludes that following the DASH diet for 8 weeks in overweight and obese women with PCOS resulted in the improvement of insulin resistance, serum hs-CRP levels, and abdominal fat accumulation [4].

    Research studies show that the monounsaturated fats and polyunsaturated fats of foods chosen in this dietary pattern can help to improve insulin, androgens, and cholesterol levels in women with PCOS.
