What are the benefits of eating bananas? Here’s 8 of the best banana benefits

1.  Bananas may be good for your heart health

A good place to start in supporting your heart health is making sure you get enough of the following nutrients:

  • Potassium
  • Fibre
  • Folate
  • Vitamin C
  • Other antioxidants
Some research has shown that people who follow a diet high in fibre have been seen to have a lower risk of cardiovascular disease than those who were eating little fibre. The people getting lots of fibre also has lower ‘bad’ cholesterol – LDL (low-density lipoprotein).4

Bananas have lots of healthy fibre, as well as potassium, folate and vitamin C, so they could help support your heart health.

2. Bananas may help you regulate blood sugar levels

Eating high-fibre diets can help to lower blood sugar levels. One medium banana provides 13% of your total dietary fibre and also gives you the energy boost from its natural sugars at the same time.

In fact, Diabetes UK state that even a large banana that contains around 30g of carbohydrates is better for diabetics than a slice of cake with 25g carbohydrates, partly because bananas have no free sugar. 5

3. Bananas may support your digestive health

Bananas can be very beneficial for your digestive health as they contain lots of dietary fibre and water.

They are also part of a treatment for treating diarrhoea called BRAT, which some doctors recommend. BRAT stands for:6

  • Banana

  • Rice

  • Apples

  • Toast

What’s more, bananas contain electrolytes like magnesium and potassium, which can often become depleted during diarrhoea.

4. Bananas could help you feel sleepy

The Sleep Council recommend eating bananas to help you get to sleep. They said that they make an ideal snack before bed as banana vitamins include potassium and magnesium, both of which help to relax overstressed muscles.

Bananas also contain tryptophan which helps to make the hormones that calm you down at the end of the day. 7

5. Bananas are very weight-loss friendly

All fruits and veggies are usually on cards for healthy weight loss, and bananas are definitely one of them.

Snacking on a banana instead of a regular chocolate bar will typically save you a few calories, fill you up much better and nourish your body with more vitamins.

Multiple studies have explored the link between diets high in fibre (from whole fruits and other sources) and long-term weight management. One review found that a lot of the research on fibre and weight management showed that high-fibre diets almost always help people to lose weight or maintain a healthy weight in the long term.8

One medium banana contains 13% of your daily recommended amount of fibre, so it could be worth incorporating some into your diet if you’re wanting to shed some lbs or just get healthy!

6. Bananas are rich in antioxidants

Bananas contain a variety of different antioxidants. Antioxidants get to work in the body protecting our cells from oxidative damage caused by free radicals.

Two of the most potent antioxidants found in bananas are catechins and dopamine, which are linked to many health benefits. 9

7. Bananas could support kidney health

Potassium is important for kidney health, and as we’ve already discussed, bananas are full of the stuff!

In fact, there have been studies that show a link between eating potassium-rich foods like bananas and reduced kidney disease risk.10

8. Bananas could help you get energised before exercise

Bananas are one of the most popular pre-workout snacks around. Going for a run? Grab a banana. Long bike ride? Bananas can help you keep going.

This is because bananas provide easily digested carbs and provide minerals to help soothe muscle cramps and soreness after exercise.

Studies have shown that they are just as good, if not better, as some sports drinks for workout energy.11

What is bad about bananas?

Not much! The only banana drawback we can think of is their relatively high sugar content. If you ate multiple bananas a day and didn’t brush your teeth you could end up with some dental and weight problems.

Is it good to eat banana every day?

Yes! As discussed above, bananas are very nutritious and can make a fine addition to any daily diet.

What happens to your body when you eat bananas every day?

It depends what else you do, as well as what else you eat and drink. But eating a banana every day could provide you with a little extra energy from the carbs and the vitamins that support your body’s natural metabolism.

Swapping a normal sugary snack for a banana every day could also help you to feel more satisfied and have a better relationship with healthy eating – as bananas often feel like a ‘treat’ due to them being sugary.
