The fear of sugar and calories in the banana makes many people apprehensive of eating this fruit.

Over 90% of calories in a banana come from the carbs present in it. As a banana gets ripened the starch in this fruit turns into sugar.

The sugar and calories in bananas also vary according to the particular variety of this fruit.

By the way, there are over a thousand varieties of bananas found all over the world but only about 20 good varieties are grown commercially.

Again, the banana also varies in size and color too.  The ripe banana contains 89 calories per 100 grams.

A medium-sized banana (7″ to 7-7/8″ long/118 grams) contains 105 calories.

The sugar present in a medium-sized ripened banana is 14 grams; a little more than a tablespoon of normal white sugar.

How many carbs are in a banana?

Banana is rich in carbohydrates and this accounts for most of the calories from this fruit. A medium-sized banana has 27 grams of carbs in it. That is about 23g of carbohydrate per 100 grams of banana.

The great sources of banana benefits for health come from potassium, dietary fiber, manganese, and vitamins B6 and C present in this sweet and delicious fruit.

In the forthcoming paragraphs below, I want to share with you the major health advantages and benefits of bananas.

1. Bananas Improve Cardiovascular Health

The banana contains only a negligible amount of saturated fat and cholesterol which makes it a good fruit for the heart.

2. Bananas Lower Blood Pressure

One of the common reasons for high blood pressure in most people is the presence of high sodium content in the blood.[8]

The banana, which is naturally rich in potassium, (3 medium size banana=1500mg potassium) can maintain healthy levels of blood pressure by neutralizing the sodium effects in the blood.[9]

For a normal blood pressure rate, it is important to maintain the right level of potassium-to-sodium ratio in the blood.  Of course, banana is the best natural food source for supplying the required potassium to the body.

3. Bananas Can Supply Magnesium Mineral

For the good health of the body, an adult person requires about 300 t0 430mg daily intake of magnesium. Consuming three bananas a day can provide our body with a good portion of the magnesium of daily requirements.

“Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation.” [10,11,12]

The strength of the bones, joints, and teeth also depends on the sufficient intake of this valuable mineral.[13,14]

4. Bananas Help In Weight Loss

Some say bananas are NOT good for weight loss because of the carbs and sugar present in this fruit.

There are ‘NO’ proven studies till now on the relation between weight loss and ripe bananas.

According to one study, unripe banana starch consumption is good for weight loss. Some of the participants on this diet were able to lose up to 2.6 lbs in 4 week period.[15]

The ripe banana can very well be part of your weight loss diet plan as this fruit contains fiber, resistant starch, and nutrients that promote a healthy metabolism.[16,17]

This fruit can suppress the appetite as it is very filling and boosts energy levels too.[16,17]

5. Promotes The Growth Healthy Body Cells

The regeneration and growth of body cells require Vitamin B6. This vitamin is crucial to the body because it assists in the production of insulin, nonessential amino acids, and hemoglobin necessary for the development of body cells.[18,19,20]

For a healthy immune system in the body, Vitamin B6 helps in generating antibodies that fight infections.[21,22]

Banana contains about 5mg of Vitamin B6 per 100 grams.

6. Bananas are Rich In Resistant Starch And Fiber

Every banana can provide your body about 3 grams of fiber.

The fiber required for proper digestion and healthy metabolism is necessary for a healthy body.

Lucky are the people who use raw green bananas in food preparation. The unripe banana contains a lot of resistant starch (indigestible carbohydrate) that acts just like fiber.[23]

The health benefits of resistant starch are great for the body. Some of the major health benefits from it are suppression of appetite, improves colon health, lowers insulin resistance, and helps in balancing blood sugar levels.[24,25,26]

The banana also contains pectin fiber that is known for its health benefits in appetite reduction, blood sugar moderation, and prevention of colon cancer.[25,26,27]

7. Bananas Improve Digestion

The resistant starch and pectin fiber present in this fruit improves the digestive process and also make us feel full and satiated. These compounds also have prebiotic nutrients that feed the helpful bacteria in the digestive system.[28]

The fibrous nutrients in the banana are fermented by the friendly bacteria in the colon that leads to the generation of butyrate.

Butyrate is a type of short-chain fatty acid that helps in the healthy functioning of the digestive system. It can also prevent colon cancer and ulcers in the stomach.[29,30]

This fruit is an easily digestible food and non-irritating for the human gastrointestinal tract.

8. Bananas Are Rich In Vitamin C

A full serving of bananas can provide your body with 15% of the daily requirement of Vitamin C.

The health benefits of Vitamin C include protecting the body from immune deficiencies, preventing prenatal health problems, better health of the eyes and skin, and helps in preventing cardiovascular disease.[31,32,33]

Vitamin C also functions as an antioxidant that neutralizes the harmful effects of free radicals in the blood.[34,35]

This essential vitamin is necessary for the production of collagen that holds muscles, bones, and other tissues together.[36,37]

9. Bananas Help In Fighting Anemia

The reason for anemia disease is the low hemoglobin count in the blood caused by the deficiency of iron minerals in the body.[38]

A good amount of iron minerals present in bananas is beneficial for the production of hemoglobin in the blood.

Every 100 grams of banana you eat contains about 3 mg of iron.

The anemia disease also gets weakened because of the Vitamin B6 from the banana that begins to regulate the glucose levels in the blood.

10. Boosts The Performance Of Athletes

The most favorite fruit of all athletes is bananas.

This fruit is easy to carry around and eat whenever and wherever you want to.

Most importantly, it strengthens and energizes the muscles and provides beneficial antioxidants and nutrients good for enhancing performance in sports.

One of the studies conducted at Appalachian State University’s Human Performance Lab came out with a valuable finding. The study members, who were professional cyclists, were given half a banana after every 15 minutes of cycling.  The results showed their energy levels were similar or even higher with those who drank a carbohydrate-matched sports drink every 15 minutes.[39,40]

There is no wonder why tennis players and athletes keep eating bananas quite often.

11. Relieves Anxiety And Lifts The Mood

The magnesium mineral present in the banana is good for relieving anxiety and lifting the mood besides helping you to sleep well.

Many of the studies have pointed out that low levels of magnesium in the body are one of the reasons for anxiety, depression, irritability, and insomnia.[41,42,43]

Eating 3 or 4 bananas a day can provide your body with a good portion of daily magnesium requirements.

Is Banana Safe For Diabetes Patients?

Most diabetes patients are hesitant to eat bananas because of the sugar and carbohydrate present in this fruit.

The glycemic index, which measures the effects of various foods on blood sugar rise, has ranked banana at low to medium level at the index value of 42–62.[44]

For diabetes patients, it is safe to eat 2 or 3 medium-sized bananas per day.

It is important to make sure that sugar and starch intake from other food sources in the diet are minimal and do not exceed the permissible level.

Diabetes patients should daily monitor their blood sugar levels and never eat a banana if the sugar level has already exceeded the healthy benchmark level.

Side Effects Of Bananas On Health

Banana is the most commonly eaten fruit. It is very friendly to the digestive system of the body.

This fruit is even recommended as the first safe, solid food that could be fed to the babies.

In very rare cases some people who are allergenic to latex may also be allergic to some varieties of bananas.

As per one of the study results, about 40% of people who have latex allergies could be sensitive to plant foods too.[45]

People who are on rigid ‘low carbs and low sugar diets’ should avoid bananas as these fruits contain a good bit of sugar and starch.

Overall, banana is a very safe and healthy fruit for all.
