Several methods of dietetic counseling can be used in the nutritional therapy in gestational diabetes mellitus (GDM). The main methods are the traditional method (TM) and the carbohydrate counting (CCM).

Presenting a systematic review of the literature on the impact of nutritional therapy in GDM, through TM and CCM, evaluating the results for maternal and child health.

We searched databases PubMed, Scopus, Web of Science, Lilacs and CAPES Digital Bank of Thesis. The methodological quality of all the studies included was made using the Jadad score.

We have found five studies that evaluated the effects of nutritional therapy, through the TM, on the maternal and child health. None study evaluating the CCM was detected in pregnant women with GDM Nutritional therapy given during antenatal care was effective in reducing pregnancy complications (preeclampsia, excessive gestational weight gain, necessity for cesarean delivery, for insulin therapy and for shoulder dystocia), perinatal complications (macrosomia, neonatal hypoglycemia, and birth weight) and also in better glycemic control. The use of nutritional therapy should be highlighted within the antenatal care for pregnant women with GDM, giving the satisfactory results on metabolic control and on pregnancy outcomes. Studies examining the CCM to GDM patients should be conducted to show its effects on maternal and child health.
