Mango Consumption Linked to Improved Blood Sugar Control, Study Finds
Consuming mangoes daily may help individuals better manage blood sugar levels and reduce body fat, according to research published today by George Mason University.
The study, titled “Daily Mango Intake Improves Glycemic and Body Composition Outcomes in Adults with Prediabetes: A Randomized Controlled Study” and appearing in the journal Foods in August 2025, revealed that participants who included mango in their daily diet experienced improved glycemic control compared to those who consumed low-sugar snacks. This finding challenges conventional wisdom about fruit and sugar intake, suggesting the nutritional context of sugar within whole foods is paramount. Understanding how diet impacts prediabetes is crucial as the condition affects millions and can lead to type 2 diabetes.
Raedeh Basiri, Assistant Professor in George Mason’s Department of Nutrition and Food Studies, explained the science behind the benefit. “It’s not simply about how much sugar food contains, but about the overall nutritional makeup,” Basiri told Science Daily. “Mangoes offer a unique balance—while they contain natural sugars, these are accompanied by fiber, antioxidants, and essential vitamins, which helps slow sugar absorption.” Mangoes have a glycemic index (GI) between 51 and 56, placing them in the low-to-medium category, according to the American Diabetes Association. A typical serving size is about two-thirds of a cup, providing around 15 grams of carbohydrates.
Beyond blood sugar, research suggests mangoes may also positively impact cholesterol levels. A 2011 study in the British Journal of Nutrition found that mice fed a high-fat diet supplemented with freeze-dried mango exhibited lower body fat and improved glucose levels. Early signs of high blood sugar, or hyperglycemia, include excessive thirst, frequent urination, and blurred vision, as detailed by the Cleveland Clinic.
Researchers will continue to investigate the long-term effects of daily mango consumption on metabolic health and explore the potential for incorporating mangoes into broader dietary guidelines for individuals at risk of developing type 2 diabetes.
