Bananas are among the most popular fruits in the world. They are best known for their high potassium content, which can lower blood pressure and is linked to a reduced risk of heart disease. But you may not have heard that bananas are also very high in magnesium. One large banana contains 37 mg, or 9% of the RDI.
Bananas also provide vitamin C, vitamin B6, manganese and fiber. Ripe bananas are higher in sugar and carbs than most other fruits, so they may not be suitable for people with diabetes. However, when bananas are unripe, a large portion of their carbs are resistant starch, which doesn’t get digested and absorbed.
Instead of raising blood sugar levels, resistant starch may actually lower them and may also reduce inflammation and improve gut health.
