Can Eating Too Many Bananas Be Bad For You? (4 Excessive Banana-Eating Problems)

I’m sure it’s something you’ve often thought about, can eating too many bananas be bad for you?

I love the yellow fruit just as much as the next person.

However, I’m sure, like me, you’ve often thought that perhaps you’re eating too many bananas.

This, of course, leads you to wonder whether all this banana eating can actually be bad for you.

Allow me to reveal all.

Eating too many bananas can be bad for you. An average medium-sized banana contains approximately 110 calories. Therefore, eating just 3-4 bananas a day could account for a high percentage of your daily calorie intake. Ripe bananas also have a high sugar content, which can lead to diabetes or heart disease. Plus, the level of sugar can also react with certain medications. An excess of bananas can lead to a wide variety of gastrointestinal issues, such as bloating, gas, and diarrhea.

1. What is the Connection Between Bananas and Calories?

Firstly, I will say that eating too much of any food can be bad for you.

So, it makes sense to eat a well-balanced and varied diet.

One of the main problems with eating too many bananas is their calorie content.

This is especially true if you’re trying to maintain or lose weight.

An average-sized banana contains 110 calories, whereas a large banana may have up to 120 calories.

So realistically, if you eat 3 or 4 bananas every day, you have consumed a fair percentage of your daily calorie intake.

Another issue here is that bananas lack protein and healthy fats.

This, of course, means that you’re mainly consuming carbohydrates, which isn’t helping to balance out your macronutrient consumption.

2. What About Bananas and Sugar?

Bananas, especially when ripe, contain a high amount of sugar.

Obviously, once more, this can impact your weight.

The carbohydrate in a green and unripe banana is typically very starchy.

However, as a banana ripens, this starch converts to sugar.

An excess of sugar can lead to various serious illnesses, including diabetes and heart disease.

In fact, if you are already diabetic or prediabetic, then you should be wary of your banana consumption anyway.

Furthermore, high levels of sugar may also interact with various medications.

So, if you do currently suffer from any illnesses or take any medications, it’s best to consult with your Doctor prior to eating bananas.

3. Do Bananas Cause Gastrointestinal Issues?

As I’ve already mentioned, eating too much of any food can be bad for you.

However, as bananas are mainly carbohydrates, both starch and sugar, they can cause various gastrointestinal problems when eaten to excess.

Additionally, as bananas contain fiber, they take longer than many other high-sugar foods to digest.

So, it’s not unheard of to suffer bloating, gas, or even diarrhea if you eat too many bananas.

Admittedly, this will be down to exactly how many bananas you eat on a daily basis.

With that being said, in order to avoid gastrointestinal issues, you should stick to no more than 1 or 2 bananas a day.

Bananas: Most Dangerous Fruit in the World

4. What About Bananas and Hyperkalemia?

One of the major benefits of eating bananas is their potassium content.

Potassium helps the muscles and nerves to function properly.

It can also regulate the heartbeat.

Plus, potassium plays a crucial role in metabolizing carbs and synthesizing proteins.

With that being said, if you have too much potassium in your bloodstream, this can eventually lead to a condition called hyperkalemia.

This is simply the medical term for someone who has too much potassium in their blood.

If hyperkalemia is left untreated, it can lead to muscle weakness and temporary paralysis and can often be the cause of serious heart problems.

Hyperkalemia is typically caused by kidney failure or kidney disease, but it can also be the result of excessive potassium consumption.

A banana contains approximately 400 milligrams of potassium, whereas a dose in excess of 18 grams of potassium can lead to hyperkalemia.

So realistically, as long as you’re not eating 45 bananas a day, you should be safe.

Well, you did ask if eating too many bananas was bad for you.

With that being said, a study by the National Institute of Mental Health found a patient with recurrent hyperkalemia who was eating up to 20 bananas a day.

Final Thoughts

So, as you can see, eating too many bananas can be bad for you.

However, realistically the same can be said for any type of food, so everything in moderation.

Bananas are daily calorie-dense and lack protein and healthy fats.

Plus, they are high in sugar content once ripened.

This can cause certain illnesses, interact with medications, cause gastrointestinal problems, and lead to weight gain.

Furthermore, excessive levels of potassium in the bloodstream can result in hyperkalemia.

Of course, this popular yellow fruit can affect your health in many ways, so let’s see if bananas contain any lactose.

  1. Hi Diane and Partha
    Glad to hear confirmation about the types of bananas with their coloring.
    Long story short or the other way around LOL

    Years ago I had a massive heart attack and was taken to the local hospital.
    They gave me all the blood thinners as I found out one artery was 100% blocked but they didn’t kick in.
    I was conscious all the time then I saw my wife and kids being moved away which I thought strange and they were there the whole time.

    Next thing I knew I woke up in an ambulance again with the doctor who gave me the blood thinners at the hospital.
    I was confused apparently I flatlined for a short while and passed out.
    The doctor told me she didn’t think I was going to make it as the meds didn’t work then but during the ride, they obviously started to kick in just in time. So I was being transferred to another hospital that had all the right equipment.
    When I got put on the stretcher at the new hospital I was greeted or more like mobbed by some resident doctors asking questions as part of their learning (why me).

    As I was on my way to surgery one of the doctors started asking me if I had diabetes.

    I thought is this guy nuts or what and told him no I am here for heart surgery as I just had a heart attack.

    But he keep insisting I had diabetes I was fully aware of where I was but still in pain but I got so close to letting him know in a few choice words but held back.

    Along the way just before we went in he mentioned I had some skin tags that gave him the indication I was suffering from diabetes which was a part factor of the heart attack.
    I never knew I had diabetes like many people around the world.

    So anyone reading this get yourself check out just in case.

    The chat ended as I went into surgery and when I woke up I saw him again and I thought here we go again round two is about, to begin with, the diabetes crap.

    They did some blood tests while I was in and found I had type 2 diabetes as well as a heart attack.
    So glad I didn’t give my choice of words.

    Later I found out from a nutritionist that I need to watch out what I eat especially with surgery food.
    She gave me a list of foods and asked me if I eat bananas I said yes love them.
    I have it often in many ways like milkshakes or in a smoother or just as they are.
    That is when I found out that Bananas that go darker have a higher sugar content than the unripped or yellow-colored bananas.

    This is why I enjoyed this post and will look at some more soon and may try some of the recipes here.

    This just adds further confirmation about how something so nice to eat like bananas can also be a health issue as diabetes also can create overtime heart issues as I had.

    So thank you for this very beneficial information on bananas.

    Keep going forward.
