Clinical Trial Summary

The objective of our study is to determine the effects of fish protein on insulin sensitivity in PCOS women with insulin resistance, and its mechanism of action on glucose and endocrine metabolism. Our working hypothesis is that dietary fish protein improves insulin sensitivity, glucose tolerance, and related plasma endocrine and lipid abnormalities in PCOS women by restoring secretory β-cell function and insulin signaling to the PI 3-kinase activity/Akt pathway. We further hypothesize that fish protein will improve cycle regularity and ovarian function.


Clinical Trial Description

Women with polycystic ovary syndrome are at high risk of developing diabetes. Apart from a primary ovarian defect, up to 10% and 40-50% of those women develop diabetes and insulin resistance (IR) respectively. IR and associated hyperinsulinemia are recognized as important pathogenic factors in determining diabetes in the majority of PCOS women, particularly when obesity is present. Treating IR might reduce the risk of diabetes and improve ovulation and fertility in PCOS women. We recently found that obese, IR men and women consuming a cod protein diet showed a 30% improvement in insulin sensitivity compared with other animal proteins, and also a 24% decrease in high-sensitive C-reactive protein plasma concentration. Therefore, dietary fish protein could represent a natural, safe and practical means to improve insulin sensitivity in PCOS women with IR, and a new non-pharmaceutical approach for the treatment of the multiple endocrine and metabolic abnormalities of PCOS women (see outcome measures for a more extensive description). ;
