Among many varieties of plantain with agronomic performance produced in Côte d’Ivoire, only three are the most cultivated because there are more resistant to climate change. There are used for up to ten preferred staple foods in which four are currently consumed notably in urban area. So, this study was focused to determine glycemic index (GI) and glycemic load (GL) of preferred foods based on these plantain so as to provide a nutritional guideline in climate change context. Excepted Roasted plantain with a high GI (GI = 89), findings showed that the most of urban area foods based on plantain have low GI with the values of 44, 39 and 45 for Klaclo, Aloco (aag6), Aloco (aag7)and Chips respectively. But their consumption should be reduced because of their GL which is up to 10. These data are very important for medical organizations and showed that climate change could affect public health in Côte d’Ivoire urban area.
