Bananas: Nutrition Facts, Health Benefits, and More

This article presents the nutritional facts and health benefits of bananas.

The theory of Human Evolution from apes goes back to the mid-nineteenth century. Today when we look at monkeys and humans, there are various similarities. The significant difference we can see is the energy level of humans and monkeys. Monkeys are considered to be one of the naughtiest animals. With human evolution, various techniques are invented, new foods are created, and our lives are entirely different from what our ancestors used to live. We live a life of luxury. And this luxury makes us shift from natural to artificial pleasures. Also, with so many advancements, we are consuming more synthetic food than natural. But the apes are still following the natural diet. And clearly, we can see the difference in the health and strength of both. Do you know what the monkeys love eating? Bananas! 

With so much going on around the world, when things are getting worse, people realise the importance of good health and are becoming fitness freaks while taking synthetic dietary supplements. These supplements help achieve our fitness goals at a fast pace but can negatively influence our health in the long run. Also, someone rightly said, ‘Health is not about the weight you lose, but the life you gain’. Instead of chasing a weight loss or gain goal, let’s become fit. The easiest thing to start your fat to fit journey is to grab and eat the nearest banana you can find. Let’s see why.

Belonging to the Musaceae family, Bananas are scientifically called Musa. These are tropical flowering plants, clearly visible by the banana fruits clustered at the top of the plant. Even though bananas hold some negative attention, in the early 20th century, they became the first “superfood” stated by the American Medical Association as a health food for children and treatment of celiac disease.

Bananas are highly nutritious. They are a source of Vitamin B6, Fiber, Potassium, Magnesium, Vitamin C and Manganese. One medium ripe banana can give you about 28g carbohydrates, 1g protein, 15g naturally occurring sugar, 3g fiber, 450mg potassium, 0g fat, and 89 calories.

Carbs: Bananas are rich in carbohydrates, mainly as starch in unripe bananas and change to sugar as the banana ripens. During the ripening, the composition of the banana changes drastically. In unripe green bananas, the starch content is about 80% of dry weight, which changes to sugar, and so the ripe bananas contain only 1% starch. The sugar in ripe bananas is mainly sucrose, fructose and glucose and is about 16% of fresh weight. The GI (Glycemic Index), which measures how quickly the starch in bananas enters the bloodstream and raises the blood sugar level, is relatively low, around 42-58, which depends on the ripeness of the banana.

Fibers: The highly found starch in bananas is “resistant starch”, which goes through the gut undigested. This starch acts like fiber. In the large intestine, it changes to butyrate by the healthy microbes by fermentation. Butyrate is a type of short-chain fatty acid that helps in better gut health. Bananas also contain other fibers such as pectin. Some of the pectin in bananas is water-soluble, which increases with the ripening and is the reason for bananas’ softening.

Vitamins and Minerals

  • Potassium: A rich source of potassium, bananas help lower blood pressure and aid for a healthy heart.
  • Vitamin B6: With a significant content of vitamin B6, a medium sized-banana can help you achieve up to 33% of the daily value (DV) of the vitamin.  
  • Vitamin C: Although mainly found in citrus fruits, bananas are also a good source of vitamin C.

Like most fruits and vegetables, bananas also contain various bioactive plant compounds as a plant product. 

  • Dopamine: Dopamine is a crucial neurotransmitter in the brain. The dopamine from bananas does not mess with the blood-brain barrier to feel good but acts as an antioxidant. 
  • Catechin: Among the many antioxidant flavonoids found in Bananas, Catechin is the major one. It is beneficial to our health and reduces the risk of a heart attack.

Bananas are the most commonly consumed fruit globally. Some of the fantastic perks of this superfood on your health are:

Cardiovascular health: Bananas are rich in potassium. Potassium is a vital mineral and an electrolyte that carries a small charge in our body. The nerve cells send out signals to the heart to beat regularly. Potassium also helps maintain a healthy balance of water in cells and reduces the effects of excess dietary sodium. An imbalance with little potassium and high sodium can lead to high blood pressure. Extra sodium can cause blood clotting and damage. Potassium helps flush out the excess sodium through urine and eases tension in the blood vessels. Rich in potassium and fiber and low sodium content, bananas are vital in heart-healthy diets like DASH (Dietary Approaches to Stop Hypertension) that require around 4,700mg potassium daily in your diet.

Digestive health: Diarrhoea patients and patients with other stomach ailments that required bland, easy to digest food were once recommended the BRAT (Banana, Rice, Applesauce, Toast) diet. With being easy to eat, bananas also help replete electrolytes like potassium lost through vomiting or diarrhoea. They also contain resistant starch that helps heal your gut. Resistant starch is present in unripe bananas and is called so because it “resists” digestion in the small intestine. Many chronic diseases, including digestive disorders, can be prevented by eating unripe bananas because this starch is the food for the beneficial microbes in the digestive tract, which help break and ferment the starch as it passes into the small intestine.

Weight Control: The notion that bananas cause weight gain has no evidence. No studies claim that bananas cause weight loss, but it has various properties that can contribute to weight loss. Bananas are rich in fiber, and high fiber foods are associated with low weight. Moreover, recent studies have found that resistant starch can be a weight-loss-friendly ingredient. It increases fullness, reduces appetite and helps in consuming fewer calories. In various studies, higher consumption of pears, apples and berries showed lower weight gain through time, but bananas also showed the same. So have the tasty, easy, on-the-go fruit on the way to your office or gym, and you can be worry-free about the myths you have heard. 

Storing the “Superfood”: There are some elementary steps to have your bananas with the best taste at the right time.

  • Do not store it in direct sunlight. Also, you don’t need any unique storage device or technique (not even a refrigerator!); just store them at room temperature.
  • Refrigerating green unripe bananas can disrupt the normal ripening and affect the taste.
  • If you find fresh ripe bananas but want to eat them the next day, you can increase the ripening process by keeping them in a brown paper bag with other ripe fruits because they emit ethylene gas that promotes ripening. Also, if you wish to slow the ripening process, store them away from other ripe fruits. Using plastic bags may cause rotting.
  • Do not use plastic bags to store bananas as it traps excess moisture, making the banana rot early.
  • The bananas in the tree ripen gradually, which is promoted by the clustering at the top and preventing excess pressure and moisture from collecting at the bottom by exposing the fruits to even amounts of oxygen.
  • When you are only getting ripe bananas in the market, don’t worry, they can also be easily stored in the refrigerator. The flavor of golden yellow bananas can be preserved for a week by storing them in a sealed produce drawer. Even though the peel may turn brown, the banana inside will be okay.
  • If you have ripened bananas that have the peel turned all brown, you can still use them. Peel and mash the bananas to use in bakery foods or freeze them to use in smoothies.

There have been several rumors surrounding bananas and their effect on human health and weight. One of the rumors is that people with type II diabetes can eat bananas or not? How will it affect them? But, you can be relieved that there is no scientific evidence to show so. Naturally, bananas are expected to immediately raise the blood sugar level with the high amount of starch and sugar. But, due to their low GI, bananas do not raise the blood sugar level as much as other foods with the same carb content. Although, it is suggested that people with type II diabetes avoid very ripened bananas in large quantities and keep their blood sugar level in check. On a different note, some studies suggest that bananas can cause constipation, while some state the opposite. If taken in moderate amounts, bananas cause no adverse effect on our health and can even boost our health naturally. 

Consuming Bananas: Consuming bananas is the easiest and a delicious way to start a healthy journey today. Bananas have a naturally sweet taste, are soft and thus tasty and easy to eat. Bananas cause no trouble in eating as they require no cutting, washing or any processing to eat. Just peel and eat! 

The best time to have a banana is in the morning. Remember not to have one on an empty stomach, as the high amount of magnesium and potassium in bananas can cause an imbalance in the blood. If you pair a banana with some other fruit or oatmeal in the morning, it can wonder for your weight loss journey.

Bananas can be used in many exciting recipes to make the food healthy and tasty. Some of the recipes you can easily make at home are:

  • Banana Oatmeal Cookies: Add some banana to your regular oatmeal cookie recipe, and a fun and exciting breakfast is ready.
  • Smoothie: Fresh ripe bananas can be added for a better and fresher taste in the morning or on-the-go smoothie. We can also use frozen banana pulp made to store ripe bananas.
