Research on mangoes has revealed that they may offer a number of nutritional perks, including: Bolstered immunity “Mangoes are high in immune-boosting vitamin C,” a culinary registered dietitian in the greater New York City area. A 1 cup serving provides two-thirds of the vitamin C you need in a day. Vitamin C plays an important role in the body’s healing process, and helps your body form blood vessels, cartilage, muscle, and collagen in bones, according to the Mayo Clinic. Improved digestive health One cup of mango contains around 3 g of fibre, which is roughly 10 percent of what you need in a day. Additionally, mangoes specifically were found to significantly improve constipation, including stool frequency and consistency, according to a study published in Molecular Nutrition & Food Research. In the study, mango was more effective than a supplement that provided the same amount of fibre (300 grams). Clearly, mangoes can be part of a balanced diet and help you maintain good health. But they’re not a cure-all and won’t magically fix or prevent disease, and they can’t make up for an otherwise unhealthy diet.
