Top Amazing Health Benefits of Bananas

By | October 25, 2016

Bananas are extremely healthy and delicious.

They contain several essential nutrients, and have benefits for digestion, heart health andweight loss.

Aside from being very nutritious, they are also a highly convenient snack food.

Here are 11 health benefits of bananas that are supported by scientific research.

1. Bananas Contain Many Important Nutrients

Bananas are among the most popular fruits on earth.

Native to Southeast Asia, they are now grown in many warmer parts of the world.

There are many types of bananas available, which vary in color, size and shape. The most common type is the yellow banana, which is green when unripe.

Bananas contain a fair amount of fiber, as well as several antioxidants. One medium-sized banana (118 grams) also contains (1, 2, 3):

  • Potassium: 9% of the RDI.
  • Vitamin B6: 33% of the RDI.
  • Vitamin C: 11% of the RDI.
  • Magnesium: 8% of the RDI.
  • Copper: 10% of the RDI.
  • Manganese: 14% of the RDI.
  • Net carbs: 24 grams.
  • Fiber: 3.1 grams.
  • Protein: 1.3 grams.
  • Fat: 0.4 grams.

Each banana contains only about 105 calories, and consists almost exclusively ofwater and carbs. Bananas contain very little protein and almost no fat.

The carbs in unripe (green) bananas consist mostly of starch and resistant starch, but as the banana ripens, the starch turns into sugar (glucose, fructose and sucrose).

Bananas are rich in a fiber called pectin, which gives the flesh its structural form (4).

Unripe bananas contain resistant starch, which acts like soluble fiber and escapes digestion.

Both pectin and resistant starch may moderate blood sugar levels after meals, and reduce appetite by slowing stomach emptying (5, 6, 7).

Furthermore, bananas also rank low to medium on the glycemic index, which is a measure (from 0–100) of how quickly foods increase blood sugar levels.

The glycemic value of unripe bananas is about 30, while ripe bananas rank at about 60. The average value of all bananas is 51 (8, 9).

This means that bananas should not cause major spikes in blood sugar levels in healthy individuals.

However, this may not apply to diabetics, which should probably avoid eating lots of well-ripened bananas and monitor their blood sugars carefully when they do.
