The Banana — A Fruit with a Story

What is the scientific name & who “discovered” bananas?

The banana belongs to the genus Musa. Most of the common edible bananas are hybrids or cultivars derived primarily from Musa acuminata and Musa balbisiana.
The domestication of bananas is ancient — archaeobotanical evidence suggests banana domestication in Papua New Guinea or Southeast Asia around 7 000 years ago.
In India, texts and historical records show that bananas were present by perhaps the 3rd century BCE when Alexander the Great’s expedition encountered them in India.
It’s not accurate to say a single person “discovered” bananas in India — they arrived via multiple waves of cultivation and trade over millennia.

The Story Behind the Banana

Bananas likely originated in the tropical forests of Southeast Asia (Malaysia, Indonesia, Philippines) and New Guinea, where wild Musa species existed with seeds.
Over time, humans selected seedless (sterile) cultivars that reproduced vegetatively (via suckers), leading to the sweet bananas we know today.
From Southeast Asia the banana spread to India, Africa and eventually the Americas via colonial trade routes.
In India, the banana became deeply woven into culture, rituals, food and medicine — the plant is often treated as sacred (banana leaves used for offerings/meals) and as a symbol of prosperity.

Amazing Facts About Bananas

• Bananas are about 75 % water when ripe (and depending on cultivar). Nutritional data for a raw banana show about 74–75 g water per 100 g.
• The oft-quoted claim that “we share 95% of our DNA with bananas” is inaccurate. What is true is: approximately 50–60% of our genes have counterparts (homologs) in bananas. But that does not mean 50–60 % of our total DNA is identical with banana DNA.
  
  For example, one source explains “About 60 % of our genes have a recognisable counterpart in the banana genome… Of those ~60 %, the proteins encoded are ~40 % identical.”
  
  
• There are over 1 000 varieties or cultivars of banana around the world.
• The modern commercial banana (the common yellow dessert banana) is essentially a clone (vegetatively propagated) of a cultivar, making it genetically uniform and vulnerable to disease.

H2: Why is Banana Offered to God?

In Indian tradition, the banana plant is considered auspicious. The leaf is often used as a plate in temple offerings; the fruit is offered to deities as a symbol of purity, fertility and prosperity. The broad leaf stands for abundance. Also, the plant has no wood (the “trunk” is actually a pseudostem) which symbolises non-rigidness and humility.
(Note: This is based on cultural/ritual significance rather than strict scientific explanation.)

What is Unique About a Banana?

• The banana plant is technically an herb (the pseudostem is not woody).
• It produces large bunches of fruit; the fruit is actually a berry.
• Unlike most fruits, bananas ripen off-the plant.
• Nutritionally, bananas offer a convenient portable snack with a good mix of carbohydrate, fibre, vitamins and minerals.
• The transition from starch to sugar as it ripens is dramatic (unripe bananas have high resistant starch; ripe bananas have more sugar).

Which Fruit Has ~95 % Water?

While bananas are about 75% water, there are fruits much higher in water content. For example, watermelon, strawberries, cantaloupe, cucumber (technically a fruit) have water contents over 90%.
So the “which fruit has 95% water?” claim may refer to watermelon or cucumber rather than banana.

Which Fruit Has ~60% of Human DNA?

As noted above, the claim that “we share 60% of our DNA with bananas” is a mis-statement. What is more accurate: humans share homology in ~50–60% of genes with bananas, not DNA.
Therefore there is no fruit that shares “60% of human DNA” in the simplistic sense.

Can Diabetes Eat Banana?

Yes — but with caveats.

• A medium banana is reasonably low–to–moderate in glycaemic index (GI), especially if it is not overly ripe.
• Unripe (green) bananas have more resistant starch and less free sugar, which slows digestion and may support better blood-sugar control.
• However: Ripe bananas are higher in sugar, so persons with diabetes should monitor portion size and pair banana with protein/fat/fibre to slow absorption.
• Always individualise: consult a dietician or physician who knows your glycaemic response.

Why is Banana Used in Ulcerative Colitis?

There is traditional/ethnobotanical use of banana plant parts for intestinal conditions. For example, the banana fruit and pseudostem fibres are used in Ayurvedic/home-herbal contexts for ulcers and loose motions.
Mechanistically:

• The resistant starch and pectin in bananas support gut microbial health and produce short-chain fatty acids (such as butyrate) which nourish colon cells.
• Bananas are gentle on the gut, easy to digest, and may help firm stools (hence used in BRAT diet for diarrhoea)
  While they are not a substitute for medical therapy of ulcerative colitis, they may form a gentle dietary support. Always check with your gastroenterologist.

Nutrients in Banana

A medium banana (~118 g) provides approximately:

• ~105 calories
• ~88 g water
• ~27 g carbohydrates (of which ~14 g sugars)
• ~3 g fibre
• Potassium (~422 mg)
• Vitamin B6 (~0.4-0.5 mg)
• Vitamin C (~10 mg)
• Other micronutrients: magnesium, manganese, small amounts of vitamins A, E.
  Also: unripe bananas contain higher resistant starch (acts like dietary fibre) and lower sugars.

Is Unripe Banana Good for Diabetic Patients?

Yes — unripe (green) banana has higher resistant starch and lower sugar, which leads to lower GI and slower absorption.
However, it still contains carbohydrates and must be counted in total carbs for the diabetic diet. The texture is firmer and taste less sweet; it may require cooking or making into flour.

Varieties of Banana & Why Jalgaon in India is Called “City of Banana”

Varieties of Banana

In India there are many cultivars with Geographical Indication (GI) status:

• Jalgaon banana (from Jalgaon district, Maharashtra) — this variety is widely grown in the region and has a GI tag.
• Myndoli Banana (Goa) — long “tusk-shaped” banana, with GI tag.
• Kamalapur Red Banana (Karnataka) — red skin banana, higher calories and vitamins.
• Kanyakumari Matti Banana (Tamil Nadu) — medicinal value, low sugar, GI tag.
  …and many more.

Why Is Jalgaon Called City of Banana?

Jalgaon district in Maharashtra is a major banana-growing region: the cultivar “Jalgaon banana” is grown widely, accounts for significant banana production of the state, and has distinct characteristics (taste, yield).
Because of its dominant banana cultivation, export, the presence of a “Horticulture Train” for banana transport, and the GI tag, Jalgaon is often referred to as the “Banana Capital” of India.

What Parts of the Banana Herb Can We Eat? Does the Peel Have Medicinal Properties? What Chemical/Phytochemical Properties Help Metabolic & Digestive Functions?

Edible Parts of the Banana Plant

• The fruit (pulp) — eaten raw, cooked or processed.
• Unripe banana — can be boiled, used as vegetable or made into chips, flour.
• Banana flower (inflorescence or “banana blossom”) — used in many Asian cuisines, has fibre and phytochemicals.
• Banana pseudostem (the “trunk” of the plant) — after harvesting the fruit, the pseudostem core is edible or used for extraction of fibre/juice in some areas.
• Banana leaves — not typically eaten, but used as food wrap; some traditional medicinal uses (compresses) exist.

Peel / Skin

Banana peel is increasingly studied for medicinal/functional properties: it contains bioactive compounds (phenolics, flavonoids, tannins, saponins) with potential antioxidant, antimicrobial properties. Some ethnomedicinal uses mention banana peel for wound dressings or as component of herbal remedies.

Phytochemical / Chemical Properties

• Resistant starch (in unripe banana) → a prebiotic effect, fermentation in colon → short-chain fatty acids (e.g., butyrate) beneficial for gut lining.
• Pectin and soluble fibre → support digestion, moderate rise in blood sugar.
• Potassium, magnesium, vitamin B6, vitamin C, and antioxidants (e.g., dopamine, catechins) → support heart health, blood-pressure regulation, mood.
• Leaves, flowers, pseudostem extracts: contain flavonoids, saponins, glycosides, etc., and have been studied for antimicrobial, anti-ulcer, anti-oxidant properties.

How Many Fruits Can We Eat Per Day? What Chemicals to Use to Ripen Faster? Does Ripening Affect Original Content Inside?

How Many Bananas Per Day?

There’s no one-size-fits-all answer: it depends on individual caloric needs, carbohydrate budget (especially for diabetics), overall diet, activity level.
For generally healthy adults: 1–2 medium bananas per day is perfectly fine as part of a balanced diet (assuming other carbohydrate sources are accounted for).
If you have specific health conditions (diabetes, kidney disease, high potassium issues, etc.), you should tailor intake accordingly.

Chemical Methods for Ripening Faster & Effect on Content

There are commercial and traditional methods to enhance ripening (ethylene gas exposure, putting bananas with ethylene-producing fruits like apples, storing at warmer temperature). As bananas ripen: starch → sugar; moisture content may shift slightly; antioxidant levels may decline slightly whereas sugar rises. So yes — ripening affects internal content: more sugars, less resistant starch.
Over-ripening may lead to higher glycaemic load for the same fruit. For people monitoring blood sugar, slightly less-ripe banana might be better.

Summary

• Eat bananas in moderation and as part of a varied diet.
• If your goal is slower absorption and better gut health, favour slightly unripe banana.
• Ripening changes sugar/starch balance.
• The “chemicals” used to ripen (ethylene etc) in approved contexts are generally safe, but over-ripe bananas may have less resistant starch, more sugars.
