                     Bananas - The 
World's 
Healthiest 
Foods
Rich in 
nutrients
One banana provides about 112 calories and 
consists almost exclusively of water and 
carbs. They hold little protein and no fat.
The carbs in green, unripe bananas are 
mostly in the form of starch and resistant 
starch a type of indigestible fiber we’ll get to 
shortly. As the fruit ripens, its flavor becomes 
sweeter while its fiber content drops

levels
Bananas are rich in soluble fiber. During 
digestion, soluble fiber dissolves in liquid to 
form a gel. It’s also what gives bananas their 
sponge-like texture.
Unripe bananas also contain resistant starch, 
which isn’t digested by your body.

May support 
digestive 
health
Dietary fiber has been linked to many health 
benefits, including improved digestion. One 
medium-sized banana provides about 3 
grams of fiber.
Resistant starch, the type of fiber found in 
unripe bananas, is a prebiotic. Prebiotics 
escape digestion and end up in your large 
intestine, where they become food for the 
beneficial bacteria in your gut.

loss
First, bananas have relatively few calories. 
The average banana has just over 100 
calories, yet it’s nutritious and filling.
Eating more fiber from vegetables and fruits 
has repeatedly been linked to lower body 
weight and weight loss.

Potassium is a mineral that’s vital for heart 
health, especially blood pressure 
management. Despite its importance, few 
people get enough potassium in their diet.

Additionally, bananas are relatively low in 
calories for their size.

Improve insulin 
sensitivity 
when unripe
Insulin resistance is a significant risk factor 
for several chronic diseases, including type 2 
diabetes.
Several studies reveal that regularly eating 
resistant starch — for example, by enjoying 
unripe bananas — may improve insulin 
sensitivity.
