01. Introduction

Do you know Banana is among one of the most important fruits in the world?? On the global level, it is produced more than apples and oranges on the industrial scale. It has become a staple calorie source due to the high carbohydrate content it has. That’s why banana has an important place in the world and when considering banana health benefits, it’ not measurable. So, in this article, we reveal some amazing health benefits of Banana.

02. What are the nutritional  and functional benefits of banana??

Banana contains a high amount of carbohydrates as it contains high amount of sugars. In addition it contains

  • Fiber
  • vitamins like vitamin C, vitamin B5 , vitamin B6 (pantothenic acid and pyridoxine respectively)
  • Choline
  • Magnesium
  • Phosphorous
  • Potassium
  • Sodium

When considering the phytochemical profile of banana, different parts have different concentrations of bioactive compounds. Banana rhizome is a rich source of polyphenol compounds which have strong antioxidant activity while banana pulp and banana fruit peel are called as the best sources of antioxidant compounds. And they contain many bioactive compounds, such as flavonoids, carotenoids, vitamin C, phenolic acids, and vitamin E that provide many human health benefits. There is a number of carotenoids present in bananas including β-carotene, α-carotene, and β-cryptoxanthin, and also the types phenols present are tannins, anthocyanin, Gallic acid, catechin, and epicatechin. [1]

You may be surprised to see the plenty of health benefits that these compounds have:

  • Catechin – Increase the plasma antioxidant activity and  the oxidation of fat
  • Gallic acid – Antioxidant effects
  • Quercetin – Encourage blood flow and improve cardiovascular health
  • Ferulic acid – Possess anti-inflammatory, antioxidant, anti-allergenic, antimicrobial   and anticarcinogenic effects
  • Tannic acid – Act as medicinal agents for the treatment in  burns
  • Coumaric acid  –  Possess antioxidant properties and lower risk of stomach cancer
  • Cinnamic acid – Act as a precursor to the sweetener aspartame
  • Trans-α carotene – Act as a Precursor to vitamin A
  • Trans-β carotene – Anti-cancer properties and improving heart health
  • Catecholamines – Elevates the glucose levels, blood pressure, and  rate of heart    

Now let’s see what are the antioxidant properties in detail.

03. Antioxidant Activity

Antioxidant Activity We prefer to eat the banana pulp not the peel. But some experts say that there is a stronger antioxidant activity in  the extract of  banana peel (catechin) than the extract of the pulp. The reason for this difference may be the antioxidant potential of the compounds.  Between the peel and the pulp extract their phenolic contents are different. However These phenolics present in banana have amazing effects in preventing cancer in the human body. According to the Bioactivity Index (BI) for dietary cancer prevention banana  is in sixth place among eleven common fruits. Apart from that phenolic acids  and flavonoids which are  also components of polyphenol compounds play a major role in antioxidant activity. [2]

  • Besides this fruit is considered as a low to medium GI (Glycemic index) food ,which makes it a favourable food for people with high blood sugar levels.

But if you are a diabetic patient try to  limit the  ripen banana consumption because they  have a considerable GI value (GI value of ripen bananas is around 60), which may increase sugar levels in the blood. But slightly ripen bananas will have no issue because their GI value is around 30.That means semi ripen bananas have better effects on your  blood sugar levels. Apart from that Insulin resistance is a vital  risk factor for most of serious diseases in the world  including type 2 diabetes. Several research studies suggest that  resistant starch in banana  can facilitate insulin sensitivity, which proves its contribution in preventing diabetes.  [3]

Banana is good for constipation too. Banana blossom has a more favorable effect to treat constipation because

  • The soluble fibers in the blossom form a gel with food materials and water making it easy to pass through the intestine.
  • Furthermore, the insoluble fibers give a bulkiness to the waste food materials. This is why you should increase the intake of banana and banana blossoms to aid digestive health.

Banana consists of the high content of phytochemicals such as polyphenols. These compounds can also survive until colon digestion. These compounds are associated with other health benefits. Dietary fiber present in banana is linked to a number of health benefits other than improving digestion. Some late researches reveal that pectin in this fruit is helpful in preventing colon cancer in addition to the above benefits. [5]

That is important in maintaining heart health. Especially this is essential for controlling blood pressure. Although the potassium level is very vital for bodily functions, few people get sufficient quantities of potassium to fulfill their dietary requirements.

Average banana fruit contains about 8% of the potassium of total nutrient content. Banana can fulfill 9% of the total dietary requirement. Therefore consume more bananas and have a potassium-rich diet which can help you to lower blood pressure. Apart from this, banana contains sufficient amounts of magnesium which may also be helpful in reducing heart diseases.[6]
