Bananas – should we eat the skin?

Todays post is about bananas and whether we should eat their skin as well.

There have been a lot of social media posts regarding this topic recently. It seems to have started with an Australian dietitian – Susie Burrell, who says we should be eating bananas skin and all.

Susie Burrell has stated that eating the peel is an easy way to boost your diet with extra dietary fibre, vitamin B6, vitamin C and magnesium. She recommends blending or baking them to break down the cell walls to make the nutrients easier to absorb – for example, in smoothies, cakes and curries.

The Pro’s and Con’s

The idea of eating the banana and the skins may seem like a good way to increase your nutrient intake.

As ripe yellow skins are rich in antioxidants that can help fight cancer, and green skins contain the amino acid tryptophan, which promotes better sleep. The skins also contain resistant start, a type of fibre that benefits gut health.

However, as vitamins C and B6 are destroyed by heat, using the skins in baking or curries to consume these nutrients doesn’t seem viable. Using them in smoothies makes more sense.

The other factor to consider is chemical absorption. The popular Cavendish variety of bananas are bred using cuttings, not seeds. That means there is no genetic diversity among the plants, and therefore they have weak immunity. As a result, it’s one of the most heavily sprayed crops. The peel, or skins, of the banana absorb some of these pesticides.

Peeled bananas are still healthy

Bananas are a great source of potassium, an essential mineral for maintaining normal blood pressure and heart function. One medium-sized banana can contain approximately 400mg of potassium.

A medium-size banana also contains about 3 grams of total fibre. Fibre is a nutrient that helps regulate the speed of digestion. When our digestion is well regulated, the conversion of carbohydrates to simple sugars and the subsequent release of simple sugars into the body is also regulated.

Approximately one-third of the fibre in bananas is actually a water-soluble fibre. Soluble fibres in food have been associated with a decreased risk of heart disease.
Within their total fibre content, bananas also contain pectin’s. Some of the components in pectin’s are water-soluble, and others are not. As bananas ripen, their water-soluble pectin’s increase, and as a result bananas become softer in texture as they ripen.

As the water-soluble pectin’s increase, so does the concentration of fructose. The mixture of the water-soluble pectin’s and fructose content helps control how fast the body digests the carbohydrates which then reduces the impact of the consumed banana on our blood glucose level.

They are low fat – 

Bananas are a very low-fat food with less than 4% of their calories being from fats. One types of fat that they do contain in small amounts are called sterols. The sterols can assist to block the absorption of dietary cholesterol. By blocking the absorption, they help keep blood cholesterol levels in check.

Therefore the takeaway from all of this,

Including bananas in your daily meal plan may help to prevent high blood pressure, improve digestion and lower cholesterol and blood glucose levels. I have previously shared some recipes using bananas that you may wish to try – SmoothiesBreakfast drinks & Seeded Banana Bread.


If you do decide to consume your bananas with the skin, make sure you choose certified organic product, and wash them well to avoid any possible pesticide residues.
I hope you found this post interesting.

Green Banana Flour

This week’s post is about Green Banana flour.

It’s relatively new to Australia, but it’s already getting a lot of attention due to its many health benefits.

What is it?

Banana flour is a powder made from un-ripe (green) bananas. Historically, banana flour has been used in Africa and Jamaica as early as the 1900’s, as a cheaper alternative to wheat flour. The flour is generally produced using green bananas that are peeled, chopped, dried, and then ground.

Is Banana flour healthy?

The flour is gluten free, high in potassium, magnesium, dietary fibre and vitamin E. It is now often used as a gluten-free replacement for wheat flours. It is also one of the richest sources of resistance starch in the world.

However, not all resistant starches are made equal. Of the handful of foods that contain resistant starch, the quantity is low and it can be destroyed through cooking or it comes from genetically modified sources. The cooking process does not destroy the resistant starch in the banana flour.

In 2013 Robert Watkins, a Queensland Banana Farmer, discovered the richest source of resistant starch in a variety of bananas known as Lady Fingers. While regular bananas (they must be green) consumed by the mass market such as Cavendish still contain resistant starch, they only contain approximately half the amount found in Lady Fingers.

The starchy unripe Lady Finger bananas are also low in sugar. As a result, the milled flour can help people better control their blood glucose. It also provides a range of digestive benefits, making it a powerful new gut health ingredient. Nutritional studies in the area of resistant starches have revealed enzyme-resistant starches produce important metabolites in the colon. These metabolites appear to have important biological effects, which can lead to improved physical and mental health.

Health benefits

The flour contains 3 different fibres

– Resistant starch, a fermentable fibre
– Inulin, soluble fibre and
– Dietary Fibre or insoluble fibre

These fibres work like a prebiotic. When the fibres enter your digestive system they encourage production of digestive enzymes that nourish the good gut bacteria and in turn heals your gut.

These fibres also increase the absorption and capacity of antioxidants and minerals. They improve colon health and aide in the prevention of colon cancer. Together the fibres also aide in the treatment of diabetes, lower cholesterol and triglyceride levels, a well as reduce the incidence of gallstones.
Resistant starch can also assist with weight loss, as you feel quite full after consuming a small amount. Resistant Starch in this form also increases metabolism and removes aflatoxins and inflammation.

Repurposed “waste”

There is approximately 500 tonne of Lady Finger bananas going to waste every week in Australia. This is due to being considered ‘unsuitable’ according to supermarket guidelines. The fruit are perfectly good for eating and packed full of nutrients yet “unwanted” by the supermarket giants because they were too straight, too bendy, too big or too small.

Rather than disposing of the tonnes of “waste” bananas, Robert Watkins developed a manufacturing process to turn the bananas into flour.

What began as a purpose and use for tonnes of wasted bananas each week has evolved into a new market for all growers. Mr Watkins is continuing to research how the nutrient dense green bananas can be utilised in different ways.

It’s fantastic to see how one farmer can have such a positive impact on a whole industry.
