Mangoes aren't off-limits for diabetics, says Dr Afeefa M Hakeem. Rich in fibre, antioxidants, and mangiferin, mangoes have a moderate glycemic index and can even improve insulin sensitivity. Portion control is key, 1/2 cup at a time, paired with protein. Avoid juices and dried forms. Mindful eating matters more than fear. This summer, enjoy mangoes wisely.
