How Many Carbs Are There in a Banana?

Bananas are a staple fruit for many people. But how does it fare against other fruits in terms of carbs, calories, and more?

The answer to this question is found on the label, which contains the number of grams and calories for each serving size.


Bananas are one of the world’s most popular fruits, but have you ever wondered how many carbohydrates are in a banana?

Banana nutrition offers various key vitamins and minerals, and carbs, which are some of the reasons bananas are so popular among athletes. In addition, bananas come in their own yellow box, making them handy to carry with you on the move.

They must, however, mature in order to reach their carbohydrate condition. After that, you may be wondering how many carbohydrates are in a banana.

A green banana has more starch than a mature banana, but it transforms to sugar as it ripens, providing carbs. Bananas are also easy on the stomach, which is why they’re a popular nutrition source for athletes.

Bananas are not all the same. Nutritionally, they’re similar; however, the number of calories varies on the banana’s size.

Continue reading to see how many carbohydrates are in a banana and how many calories are in a banana.

What Is the Carbohydrate Content of a Banana?

A medium banana has roughly 100 calories; however, as with other meals, portion size matters. Here’s a banana chart to help you figure out how many calories and carbohydrates a banana contains:

  • 72 calories, 19 carbs, extra tiny (less than 6 inches, 81 grams)
  • 90 calories, 23 carbs in a small (6–7 inch, 101 gram)
  • 105 calories, 27 carbs, medium (7–8 inches, 118 grams)
  • 121 calories, 31 carbs, large (8–9 inches, 136 grams)
  • 135 calories, 35 carbs, extra big (9 inches or longer, 152 grams)
  • 134 calories, 34.2 carbs (1 cup, 150 grams)
  • 200 calories, 51.3 carbs (1 cup, 225 grams)

The banana plant, which belongs to the Musaceae family, may reach a height of 10 to 26 feet. Bananas grow in enormous clusters of 50 to 150 bananas each.

Then, inside each cluster, there are smaller groupings known as bunches. Each bundle is referred to as a “hand,” and it might include anywhere between 10 and 25 bananas.

Bananas have carbs similar to other carbohydrates; the difference is in fiber content. While a banana includes more carbohydrates than an orange, it also contains fiber and starch, which may help you feel satisfied for longer since carbohydrates break down quickly and induce satiety.

Fiber slows the absorption of carbohydrates into the circulation.

It’s worth noting, though, that bananas have a higher impact on blood sugar levels than oranges or strawberries. This implies they contain more carbohydrates and, as a result, a higher glycemic index and glycemic load.

The glycemic index and glycemic load are two measurements of blood sugar levels that diabetics should be aware of. Despite this, many people believe that eating a banana is an excellent way to keep blood sugar in check.

Bananas are particularly popular among those who follow a carb cycling diet, which involves eating more carbohydrates on some days and fewer carbs on others. So, how many grams of carbohydrates do you need every day, and how many carbs do you want to eat in a banana?

If you’re physically active, you should get roughly 40% of your calories from carbohydrates, 30% from protein, and 30% from fat in general.

In general, you should take between 500 and 800 calories per day from carbohydrates, which equates to roughly 150 to 200 grams of carbohydrates per day — 200 is the highest number and goes as low as 120, which may be appropriate for many people attempting to lose weight.

Bananas are an excellent source of some of these carbohydrates, and one to two per day, depending on the size of the banana and how many carbs you consume from other sources, is a decent amount.

Banana Carbs’ Advantages

1. Ensure proper cell function and energy

Carbohydrates remain the body’s primary source of fuel, or energy, despite popular low-carb diets. So let’s take a closer look at how this works.

When you eat, your body breaks down the food into sugars and starches in order for it to be taken into circulation.

Sugars and starches are transformed to glucose as a result of this process. Blood sugar is another name for this.

This is critical because your body needs glucose to operate correctly. In addition, it keeps the mind alert while also providing energy for everyday jobs and exercises.

Have you ever heard of ATP or adenosine triphosphate? Within the cells, ATP is a major source of energy.

After digestion, ATP is produced by a natural chemical reaction and may be made from carbs, proteins, or lipids. What matters is that cells use ATP to power normal cellular activity.

Bananas are one of several foods that include ATP from both plant and animal sources. Bananas contain plant cells that store ATP, so when you eat one, it’s converted to glucose, which is then utilized to produce ATP as needed by the body.

2. Aid in Digestion

Bananas have a low glycemic index (GI) value. The GI determines how a meal affects the body’s blood sugar levels.

So, how does a super-sweet banana fit into the glycemic index category? It’s all about the fiber.

Fiber aids in the digestion of food at a pace that our bodies can handle. This enables faster conversion of carbohydrates to simple sugars, resulting in a much simpler digestive process.

Pectins are also found in bananas. However, pectin is a difficult sort of fiber in that some of it is water-soluble while others aren’t.

The number of water-soluble pectins in the banana increases as it ripens, causing it to soften. This process raises the amount of fructose in the banana, which helps regulate the pace of “carbohydrate digestion,” which is another reason to consume ripe bananas rather than green ones.

Further, bananas’ fructooligosaccharides (FOS) contribute to a smoother digestive process. FOS are fructose-rich carbohydrates that are often not broken down by digestive enzymes.

They make their way to the lower intestine, where beneficial bacteria finally digest them.

This is why repairing a leaky gut is so important. A leaky gut may hamper this and other digestion processes. Keeping beneficial bacteria in the lower intestine, such as Bifidobacteria, may help with overall digestive health.

3. Athletes may benefit from a mental and physical boost.

Ultra runners were studied to find out what they liked to eat before, during, and after an endurance run. Bananas seemed to be a clear favorite throughout the race, perhaps due to both the energy from glucose and the ease of digestion, but the research did not specify why.

This is due to the fact that bananas and other fruits increase productivity.

Another Cornell University research had participants jogging for 90 minutes and then cycling for 90 minutes or cycling till they were exhausted. Finally, a placebo, a banana mix, or a solid banana were administered to athletes.

The solid banana was shown to be quite efficient in improving endurance exercise performance in the trial.

According to the International Society of Sports Nutrition Journal, young gymnasts aged 12–14 were given carbohydrates to assess performance in exhausted athletes. Those that were fed carbohydrates were more attentive throughout their performance routines and had fewer falls.

Bananas are an excellent source of energy for athletes and everyone who engages in physical activity, but they should be consumed an hour or two before the event. This is because eating just before an event might reduce performance and make you feel uneasy since the body will divert blood flow to the stomach for processing.

Plantain vs. Banana

You may be asking about the differences in plantain vs. banana carbohydrates and how many carbs are in a plantain vs. how many carbs are in a banana with all this banana talk. So let’s clear the air by knowing a little more about the plantain.

Plantains and bananas have a lot in common, so it’s no surprise that they’re in the same family. Plantains, on the other hand, have more starch than bananas.

Plantains are usually served cooked, with the riper varieties being used in desserts.

In terms of carbohydrates, here’s how they compare:

How much carbohydrates and calories are in a banana (raw):

  • 134 calories, 34.2 carbs (1 cup, 150 grams)
  • 200 calories, 51.3 carbs (1 cup, 225 grams)

How many carbohydrates are in a plantain + how many calories are in a plantain (cooked):

  • 179 calories, 48 carbs (1 cup, 154 grams)
  • 232 calories, 62.3 carbs (1 cup, 200 grams)

How to Include Bananas in Your Diet

A variety of variables determines the number of bananas you consume every day or week.

If you’re on a low-carb diet, you should eat fewer bananas and keep track of your consumption. If you’re fueling your exercise with bananas, eating one around an hour before your workout may help you have a terrific workout session.

Another element to consider is the potassium content of bananas. Although potassium is a necessary vitamin for the body, some experts believe that too much potassium might create issues in those who have renal disease.

A healthy individual, on the other hand, would have a hard time overdoing bananas, according to the BBC: “You’d probably need approximately 400 bananas a day to build up the type of potassium levels that would cause your heart to stop pumping… Bananas are not poisonous, and they are, and always have been, quite healthy.”

Moderation is vital in most things in life, but try utilizing bananas to feed your body for a sharp mind and a fantastic exercise. It’s acceptable to have one or two bananas every day, but if that’s too much for you, limit yourself to two or three per week, along with a well-balanced diet, to ensure that your body gets the most out of the nutritional advantages they provide.

Banana Recipes with Fewer Carbs

Bananas may be eaten alone, in a smoothie, in overnight oats or chia pudding in the morning, in baked products, frozen – the possibilities are unlimited.

Side Effects and Risks

Bananas are an excellent energy source and have a slew of additional advantages. However, if you develop an allergic response to bananas, stop eating them right once and seek medical advice.

We are unaware of any health dangers connected with bananas, but if too much sugar causes headaches or weight gain, or if you have potassium-related problems, take it in moderation and/or seek medical advice.
