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 – Smoothies, Breakfast 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.

The Gut – Brain Connection

Today’s post is about the Gut – Brain connection.

Last week I read an article about studies in the UK and Australia, which found that eating fruit and vegetables makes people happy.

The U.K. study of 45,000 people concluded that eating fruit and vegetables several times a week, generated an increase in life satisfaction.

The Australian study consisted of more than 7000 people. It found a link between a diagnosis of depression and the minimal consumption of fruit and vegetables.

The reason behind these results is the gut microbiome.

I have previously written about different aspects of our gut microbiome in relation to our health. (Red wine and Gut health, Gut health and Strawberries, Smoothies)

Today I will write about the gut connection with the brain and how that can impact on our health. Scott is currently studying this particular subject at the moment, so I have lots of research material at my disposal.

About the microbiome

The human gut microbiome contains resident microorganisms including bacteria, viruses, fungi and protozoa. These have an important role in nutrient and mineral absorption. In synthesis of enzymes, vitamins and amino acids, and production of short-chain fatty acids. They assist with energy extraction from diet, with metabolism and help control local inflammation.

Several studies have shown that the intestinal microbiome are integral in modulating the risk of several chronic diseases.

At the same time, it is now understood that diet plays a significant role in shaping the microbiome. Experimental studies showing an acute change in diet can induce temporary changes within 24 hrs.

These recorded benefits have led to further study in the ability to modify the gut microbiota through diet.

The brain connection

Our brain, being the major part of our body’s central nervous system is always in communication with the gastrointestinal tract, or gut. There is mounting data that gut microbiota is the source of a number of substances which affect regions of the brain.

These regions are involved in the control of emotions, cognition and physical activity.

On the flip side, studies also suggest that overwhelming systemic stress and inflammation can also produce acute changes in the microbiome.

All of this research is telling us that the brain and the gut have a very interdependent relationship.

and then diet…

Studies as early as 1977 showed that diet could effect the composition of the gut microbiome. Since then, hundreds of different studies and experiments have been conducted in this field.

Several diets, including Western, gluten-free, omnivore, vegetarian, vegan and Mediterranean, have been studied for their ability to modulate the gut microbiota.

Across the spectrum of studies, the Mediterranean diet is highly regarded as a healthy balanced diet. Most notable is the high intake of fibre and low glycemic carbohydrates. There is also a relatively greater vegetable intake than animal protein. These are important factors in keeping the gut microbiota balanced, which is critical for a healthy immune system.

The close relationship between diet, the gut microbiome and health, shows how we may improve our overall health by modulating our diet.

Already the gut microbiome has been found to influence the response to cancer immunotherapy. Alterations of gut microbiota have also been associated with treating mood and depressive disorders.

So the takeaway from this research is – eat fruit and vegetables regularly to maintain good gut health and good mental health.

Red Wine and Gut Health

Todays post is about how red wine can assist our gut health.

I have written previously about the health benefits of red wine. The good news is, now there is more evidence available.

Drinking a daily glass of red wine not only tastes good to many people, but it’s also good for the bacteria lining your large intestine.

A new Spanish study suggests that sipping about 266ml of Merlot or a low-alcohol red wine changed the mix of good and bad bacteria typically found in the colon in ways that can benefit your health.

 Bacteria and the gut

Bacteria may sound like a bad thing to have in your intestinal tract, but having a balanced mix of them actually helps to digest food, regulate immune function, and produce vitamin K (which plays a key role in helping the blood clot).

Previous research has looked at whether polyphenols in the diet can influence the balance of intestinal bacteria. The latest study sought to explore whether drinking red wine can have a similar effect.

 What are polyphenols?

Polyphenols are helpful plant-based compounds found in a variety of foods and beverages. Besides red grapes, many other fruits and vegetables are rich sources of polyphenols, as are coffee, tea, chocolate, and some nuts.

 The good news

This study found that moderate consumption of red wine resulted in increased production of beneficial gut bacteria. It also had beneficial effects on blood pressure and total cholesterol levels. The study also found that that consuming 100ml of spirits daily can damage gut bacteria, this was due to the ethanol content.

This study revealed that the accompanying substances (polyphenols and tannins) actually provide health benefits, and in fact neutralise the damage caused by the ethanol in the wine.

One important thing to remember: it is best to drink wine with or after food.

The food slows down the absorption allowing the polyphenols and tannins time to exert their health benefits. When drunk on an empty stomach, around 80% of the alcoholic beverage passes into the upper small intestine for absorption. The health benefits will be missed and the ethanol will actually cause damage.

 What about beer?

Although it has not been studied extensively, scientists consider that moderate consumption of beer may have similar health benefits. The antioxidant content of beer is equivalent to that of red wine. However the specific antioxidants are different due to barley and hops containing different flavonoids to grapes.

So, enjoy a nice glass of red with your meal for better gut health.
