Bananas set a tropical mood

I eat bananas because each and every time I do, I feel a small dose of tropical.  A song in my head has some steel drums. What a delight; bananas!

I live in the cold north, and just about every day of my life I eat a banana.  It’s cheap, it’s easy to find, it’s fast food. Bananas are a little dose of tropical in my otherwise chilly days.  Even in June, my hands are chilly, I’m wearing fleece. Don’t laugh, it’s true.

We all have deep reasons for why we eat what we do beyond taste, but I simply love bananas.  Green ones, ripe ones, dark-brown ones, and everything in between. They are great mixed up with other fruits.

My kids aren’t as enthusiastic about them as me.

Oh well, all the more bananas for me! I wanted to learn more about them so I can share them with you.  From banana’s origins to the biochemistry, here we go!

Banana’s deep roots

Native to Asia, and Australia, they are thought to be first domesticated in Papua New Guinea and Africa as early as 5000-8000 BC based on archaeological data [R]. The world fell in love with bananas and is still part of trade agreements and trade wars.

Banana plants are the largest herb on the planet.  That’s right, the banana plant is technically an herb.

The type of bananas most commonly eaten in the United States are the sweet Cavendish bananas.

Bananas facts you should know for health

Not that long ago, bananas didn’t get the nutritional respect they deserved. Scientists believed they had a sprinkling of minerals, vitamins, and fiber.

We now know this isn’t true; bananas are complex and rich in antioxidants!

Bananas have a ton of health benefits.  This is partially due to their antioxidant content.  One distinct antioxidant in bananas is called gallocatechin.  This is highest in the peel. Yes, the peel is edible [R].

Dopamine, a type of antioxidant, is also a neurotransmitter that is present in high amounts in bananas [R].  Bananas also have L-dopa [R].

Bananas Facts: They Have Green Tea Compounds

Green tea gets a lot of health notoriety, while bananas don’t.  I’m here to change that!

Catechins, present in green tea, give green tea its health benefits.

A little-known fact is that bananas are also rich in catechins.

Catechins have numerous potential health benefits, including [RRR]:

  • Reducing inflammation
  • Improving blood glucose
  • Reducing bone breakdown
  • Reducing cancer spread
  • Anti-cancer effects against skin cancer, including melanoma

Bananas Facts: They Have Natural Dopamine and L-dopa

Bananas are one rare food; they contain high amounts of dopamine and also L-dopa [RR].

Dopamine is a reward neurotransmitter, but also is an antioxidant.  Dopamine motivates you into action and gives you pleasure from your daily activities, such as exercise, hobbies, social activities, and sexual interactions.

Dopamine makes some people more resilient to stress and depression as well.

While dopamine is just one of many substances playing a role in mood and pleasure, it may be a reason to reach for a banana instead of an energy drink! Some people supplement L-dopa from Mucuna pruriens for a mood-enhancing benefit. Personally, I recommend trying bananas!

Tip: Little is known about the effects of dopamine and L-dopa from foods, but we do know that dopamine in the brain plays a critical role in a healthy mood and in reward from daily life.

Bananas Facts: May Protect the Skin

Bananas also may help protect the skin.  This is because bananas are rich in an antioxidant called hydroxycinnamic acid  [R].

Hydroxycinnamic acid may also protect the skin by [R]:

  • Providing UV protection
  • Maintaining collagen
  • Reducing inflammation
  • Providing antioxidants

This antioxidant in bananas may also help curb obesity by reducing inflammation in the body [R].

Bananas Facts: They Have Proanthycyanins

Bananas also contain proanthocyanins, a type of polyphenol.  Proanthocyanins first got a lot of attention due to their health benefits discovered in grapes.

Proanthocyanins may [R];

  • Protect nerve function
  • Reduce UV damage
  • Improve blood pressure
  • Reduce retinal damage
  • Help improve vein function

Banana Facts: Rich in Nutrients

Bananas are a nutritious food, contrary to popular belief, and are not fattening.

Bananas contain high amounts of potassium, magnesium, and vitamin B6, and even contain a good amount of vitamin C. They also are fiber stars, with lots of soluble fiber.  Soluble fiber acts to increase gut health and improve nutrient absorption.

However, the form of vitamin B6 is sadly not very usable by the body. 

Nutrition information per 100 gram of bananas [R]:

Other interesting banana facts for health

Bananas are 78% water! Water is an important nutrient and most fruits have high water content.

The carbohydrate types for a green banana and a ripe banana vary considerably.

Green Bananas: Green bananas contain a high amount of resistant starch.  This makes them a prebiotic.  Green bananas have less overall absorbable carbohydrates than ripe bananas.  This makes them more suitable for people with diabetes.

  • Prebiotics in bananas feed the healthy bacteria in our gut to help them thrive.
  • Green bananas have a low glycemic load.

Ripe Bananas:  As the banana ripens, the resistant starch turns into a sweeter, simple sugar.

  • As a banana ripens, its antioxidant content increases!
    • Good reasons to eat bananas in both stages of ripeness.

Health Tip: Bananas are one of the best food sources of vitamin B6.

  • Vitamin B6 is a nutrient that is important in protein metabolism, mood regulation and so much more.
  • Over 10 percent of the population may have inadequate B6 blood levels [R].

Banana Facts: Why Choose Organic Bananas?

Organic bananas by The Healthy RD

Bananas, however, carry a dark side for the individuals growing these crops and also for the environment due to clear-cutting practices and chemical use.

Because banana market prices are stagnant, the farmers continue to live in poverty in developing regions.

Profits are almost exclusively given to monopoly-type companies that dictate farming practices. The growers are exposed to threatening chemical toxins and unfair wages.

While these chemicals are banned in the United States, they are widely used in banana production in other countries where the majority of bananas are produced. This puts the farmer at risk due to exposure. Child labor is also a reality in banana farming [R].

Chemical pesticides also leach into the soil and make their way into the soil and run off into water sources.


Banana Facts: Finding Fair Trade Bananas

Seeking Fair Trade and organic bananas supports a fair income for farmers and also supports their safety.  Fair Trade bananas can be challenging to find.  

You can also click here to find out which markets in your area sell Equal Exchange bananas.

At as little as ten cents more per pound, it seems worth the extra price. You, the consumer, hold the key to change in farming practices!

Cavendish bananas are very susceptible to fungal, pests, and viral diseases; these diseases are linked to warming climate temperatures.

Efforts are being made to strengthen the banana plant through growing new varieties of Cavendish bananas [R].

Additional banana facts

While I eat bananas at all stages, I understand that doesn’t suit everyone’s palate.

If you don’t like ripe bananas:

    • Simply peel your ripe bananas and toss them in a freezer storage bag or bowl.
    • Take them out of the freezer whenever you want to make a smoothie or bake a nutritious snack.
  • Choose Fair Trade and organic when possible
  • For a low glycemic index snack, enjoy green bananas
  • To get more antioxidants, enjoy bananas when ripe
  • Choose a banana post-workout for a great potassium replacement

Banana precautions

While banana facts are fun and generally bananas are very healthy, there are a couple of things to consider:

  • Make sure to factor in the carbohydrate content if taking medication for diabetes
  • Don’t eat bananas if you have an allergy. If you are sensitive to latex, you may also be sensitive to bananas.
  • If your doctor tells you to limit potassium, you should minimize your intake of bananas.
