A medium banana (about 7–8 inches long) has around 105 calories. It is rich in carbohydrates (27g), including 14.4g of natural sugars. This fruit has 3.1g of fiber (10% DV) and very little fat (0.4g). It also contains 1.3g protein.
Key nutrients in a medium banana:
- Potassium: 422mg (9% DV) helps the heart and muscles stay healthy.

- Folate: 23.6mcg (6% DV) supports cell growth and is important during pregnancy.
Health Benefits of Bananas
Digestive Health
One of the top banana benefits is improving gut health. Bananas are rich in dietary fiber. This nutrition helps maintain regular bowel movements and prevent constipation.
- Soluble fiber helps slow down digestion and control blood sugar. It also lowers cholesterol and keep you feeling full.
- Insoluble fiber adds bulk to stool. It speeds food passage through intestines. This aids digestive health and reduces bloating.
Unripe bananas contain resistant starch. This starch doesn’t get digested right away but feeds the good bacteria to the gut. This keeps your digestion and immune system healthy.
If your stomach feels upset, bananas are a gentle food to eat. They’re part of the BRAT diet (Bananas, Rice, Applesauce, Toast), which helps when you have diarrhea, vomiting, or nausea. Bananas also aid hydration and calm the stomach.
Heart Health and Blood Pressure
Bananas are rich in potassium, which is good for heart. Potassium helps balance sodium in the body. It may lower high blood pressure and reduce the risk of stroke.
Studies show a potassium-rich diet can cut heart disease risk by up to 25%. Research found higher potassium intake reduce the risk of heart diseases.
Bananas also have magnesium, which helps keep your heartbeat steady and relaxes your blood vessels. Together with potassium, it aids heart health and lowers high blood pressure (hypertension).
Blood Sugar Control and Diabetes
Bananas have a low to moderate glycemic index (GI):
- Unripe bananas: GI 47 (low)
- Ripe bananas: GI 57 (moderate)
The glycemic load (GL) in a medium banana is 7–9. Fiber and resistant starch help the body absorb sugar more slowly. This stops blood sugar from rising too fast.
People with diabetes can still eat bananas but in small amounts. It’s best to eat a banana with protein or healthy fat like peanut butter or Greek yogurt. This keeps blood sugar more steady.
Notes:
- Glycemic index (GI): A score that shows shows how quickly a food raises blood sugar. Low GI foods cause a slower rise; moderate GI foods cause a moderate rise.
- Glycemic load (GL): A measure of how much sugar in one serving will impact blood sugar. Lower GL means less impact.
Weight Loss and Satiety
Bananas can help with weight control. One banana has about 105 calories and a lot of fiber. The fiber helps you feel full, so you’re less likely to overeat.
Studies show that eating more fiber can help lose weight.
A banana snack gives you key nutrients without much calories. It benefits for weight control.
Energy Boost and Athletic Performance
Athletes often choose bananas for quick energy. They have glucose, fructose, and sucrose. These natural sugars give a fast boost. Unlike processed snacks, bananas do not cause a crash.
Electrolytes (like potassium and magnesium) help prevent muscle cramps and boost recovery. Studies show bananas may improve endurance and ease muscle soreness. They’re great before or after a workout.
Immunity and Disease Prevention
Bananas support the immune system with vitamin C and antioxidants. A medium banana gives about 12% of daily vitamin C needs. This vitamin enhances white blood cells and fights infections.
They also have dopamine and catechins. These antioxidants reduce inflammation and fight oxidative stress. They may help prevent chronic diseases such as cancer, heart disease, and brain issues.
Benefits of Banana for Skin and Hair
Bananas have antioxidants and vitamin C that are good for your skin. They help make collagen and protect skin from damage. A banana face mask can hydrate dry skin and give it a fresh glow.
Mashed bananas also work as a natural hair mask. They have healthy oils and vitamins that reduce breakage and add shine.
