Bananas are among the most loved fruits around all over the globe.

They are incredibly healthy and are packed full of vital nutrients.

Everyone knows that bananas are highly nutritious, but many wonder what carbs and calories they have in them.

The Number of Carbs in a Banana?

Bananas are made up mainly of carbohydrates and water. Therefore, those who monitor their carb intake must stay clear of the delicious fruit.

This is the entire list of carbs found in usual bananas:

  • The extra small was 19 grams:(81 grams)
  • The small contained 23 grams:(6-7 inches 101 grams)
  • The medium was 27grams:(7-8 inches, and the weight was 118 grams)
  • The large was 31 grams:(8-9 inches and 136 grams)
  • The extra-large amount is 35 grams:(9 inches or more (152 grams or more)
  • Sliced comprised 34 grams:(1 cup 150 grams)

Banana also has two grams of fibre, dependent on the size. In addition, you’ll consume fewer carbohydrates if you’re comfortable eating unripe or green bananas.

Unripe (green) Bananas Contain More Resistant Starch.

The essential nutrient in bananas is carbohydrates; however, carbs’ composition alters dramatically during the ripening process.

Unripe bananas have large amounts of starch. Certain varieties are intolerant to starch.

Because the starch contained in the banana is converted into sugar as it ripens, the yellow ones have more resistant starch than those with green. In the end, the content of resistant starch of the fully ripe banana is lower than a percent.

Resistant starch is classified as an indigestible carbohydrate that can be absorbed by the body and utilized to create fibre for our body.

It enters the colon undigested. It is a source of food for friendly gut bacteria.

As the bacteria digest resistive starches, they create gas and short-chain fatty acids (SCFAs), which are crucial for digestion health.

The majority of SCFAs then are rapidly taken up by cells in the colon and utilized by the body to generate energy.

Although resistant starches may not produce more calories than regular carbs, they can transform into SCFAs, which provide the last calories.

So, yellow and green bananas provide the same calories in the end.

Bananas are Also a Source of Healthy Nutrients.

Bananas are made of various minerals and vitamins.

One medium banana contains (1Trusted Source):

  • Fibre: 3.1 grams
  • Vitamin B6: 25% of the DV
  • Vitamin C: 11% of the DV
  • Manganese: 14% of the DV
  • Potassium: 12% of the DV
  • Folate: 6% of the DV
  • Riboflavin (vitamin B2): 5% of the DV

Bananas are delicious and healthy. They are a great fit, nutritious, and low-calorie snack.

Look for ripe bananas that have brown spots. If they’ve completely turned brown interior, they’re probably too mature. However, you can make them gluten-free by utilizing gluten-free oats to reduce any contamination risk from wheat.

Health Benefits

Bananas are a well-known fruit with numerous benefits in addition to the post-run dose of potassium. Here are some ways in which bananas could boost your health.

Improves Diabetes Management

The green banana is abundant in resistant starch, which acts as a fibre during digestion. Because of their advantages for health, they are usually crushed into pulp or flour. They are employed as functional ingredients in food products and research studies.

A comprehensive review of several studies showed that green banana flour is effective in enhancing insulin sensitivity, aiding weight loss, and lessening specific liver and kidney problems associated with diabetes. All are beneficial for the long-term management of the disease.

Promotes Regularity

Bananas are a great source of prebiotics, fermentable fibres that provide “good bacteria,” or probiotics, inside the digestive tract. 9 Prebiotics assist digestion by promoting the development of bacteria that aid in digesting food. Combining bananas and foods with living culture (such as yoghurt) is a fantastic method to improve digestive health, digestion and regularity.

Further, studies looking at the effects of green bananas have shown benefits for diarrhoea and constipation treatment for kids. 8 Eating bananas is an easy method of getting the digestive system back on the right track.

Aids Weight Loss

The banana has earned a bad reputation due to its high amount of starch; however, it’s a highly low-calorie food full of nutritious fibre to help you reach your weight reduction goals. With 3g of fibre 100 calories, bananas are an excellent way to be satisfied and not overeat.

Research has shown a link between higher intake of fibre in addition to calorie reductions, which can lead to weight loss. For example, a pooled study estimates that adding 14g of fibre to the diet (or cutting calories by 10%) each day can reduce by 4.4 pounds over four years. 10 Bananas for breakfast or snack selection can help you reach and keep your weight in check.

Lowers Blood Pressure

Bananas are an excellent source of potassium as a medium size banana provides around 9% of the daily amount for most adults. In addition, the ability of potassium to lower blood pressure potassium is well-established, especially when it’s paired in conjunction with the DIASH lifestyle or a low-sodium diet.

Bananas are a staple in the diet that contributes to the daily requirement for potassium to lower blood pressure and avoid complications like kidney diseases and strokes. So do yourself and your body a favour by opting for an apple over an unhealthy snack. A higher intake of potassium may help aid in preventing hypertension by increasing the levels of sodium that your kidneys release.

May Assist Wound Healing

The anti-inflammatory and antioxidant properties of banana peels have gained them a place in traditional medicine for wound treatment. The peels of bananas are applied to the bites of mosquitoes or on minor injuries to provide relief and protect the healing process.

While this effect might not be supported entirely by modern medicine, bananas contain nutrients that heal wounds, such as vitamin C and other antioxidants when consumed. One medium banana contains around 11% of your daily requirements. Vitamin C is an ingredient that helps create collagen, which is a vital ingredient in maintaining the integrity of your skin.


Food allergy to bananas is possible; however, they are not common. Some people suffer from the condition known as oral allergy syndrome (OAS), where pollen allergens react with fruit, such as bananas. Banana allergies are also related to latex allergies caused by natural rubber. Studies have shown that 20 to 50% of people suffering from latex allergies react to bananas.

Allergies can manifest as dizziness, vomiting, hives and shortness of breathe and even anaphylaxis. While it is not well studied, cases of acute pancreatitis have been documented due to an allergy to bananas in the food chain.

If you suspect an allergy to bananas or other fruits, consult an allergist for a thorough assessment.

Adverse Effects

While bananas are generally healthy for digestion, some people may suffer constipation when they increase their fibre intake from food such as bananas. Imagine that you’re not used to eating a large amount of fibre. In that case, you should increase your intake slowly and drink lots of fluids to help your body adapt to a higher fibre intake.

Storage and Food Safety

Bananas can change from yellow to green to brown when they mature. If you purchase green bananas, you may let them develop independently at room temperature. To accelerate the ripening process, put the green bananas in a bag made of paper or set them next to other ripe fruits. 11 Don’t place fruits in bags made of plastic because this can trap moisture, which causes them to begin to rot.

If the bananas are at the desired level of yellow colour, you can peel them and enjoy them. However, suppose you cannot get to them immediately. In that case, you can store fresh bananas in the refrigerator and buy an additional week. Of course, the peel could change to darker brown or even black when stored in the fridge, but it doesn’t impact the fruit’s goodness.

Peel the ripe bananas, smash or cut them into slices and put them in freezers by sealing them in airtight bags. This can use in smoothies or baking later in the process. It’s not necessary to wash or blanch the bananas before freezing. However, ensure to wash your hands after taking them.

How Many Carbs in a Banana

Bananas usually contain between 7 and 19 grams of carbohydrates, based on their size.

How Many Calories Are In A Banana?

A medium banana contains 105 calories, on average. Much less than other varieties of fruit, like apple, pear, or pineapple. But the different sizes of bananas have different quantities of calories.
