Top 5 health benefits of bananas

The Health Benefits of Bananas PIN

1. Bananas are a powerhouse of nutrients

One medium banana is much more than just a sweet treat – it’s practically a multivitamin in itself! Each banana contains a variety of essential vitamins and minerals. When I say “bananas are a good source of nutrients,” I really mean it. Here’s why:

Bananas contain dietary fiber, which aids digestion. They’re rich in vitamin C, a powerful antioxidant that helps your body build and repair tissues, and vitamin B6, which your body needs to break down food, keep your nerves working properly, and produce red blood cells.

They also contain potassium. But, what does potassium do, you might ask? It’s a mineral that helps regulate fluid balance, nerve signals, and muscle contractions. If you’re looking to bolster your heart health, keep in mind that one medium banana provides about 9% of your daily potassium needs.

Last but not least, bananas are rich in magnesium. This nutrient is key for the body’s metabolism and also helps keep your bones strong and your heart rhythm steady. In a nutshell, the humble banana contains a mix of nutrients that can keep your body running at its best.

2. Bananas may boost digestive health

A healthy gut is key for overall health, and bananas are excellent for your gut.

The dietary fiber in bananas, around 3g in a medium-sized banana, aids digestion and helps prevent constipation by softening your stools and supporting regular bowel movements.

Bananas also contain a type of fiber called pectin, which gives the flesh its spongy structural form. Interestingly, the amount and type of pectin in bananas changes as they ripen.

Unripe bananas contain resistant starch, which functions like soluble fiber and escapes digestion. Both pectin and resistant starch may moderate blood sugar levels after meals and reduce appetite by slowing the emptying of your stomach.

3. Bananas are a good source of antioxidants

Free radicals are molecules that can damage your cells and contribute to aging and diseases. But worry not! Bananas contain several potent antioxidants, including dopamine and vitamin C, which can fight inflammation in your body.

Dopamine in bananas acts as a powerful antioxidant. However, this compound isn’t the same as dopamine in the brain – it does not cross the blood-brain barrier and doesn’t have the mood-enhancing properties.

But it’s a strong antioxidant that reduces inflammation and potential damage from free radicals.

4. Bananas may aid heart health

Potassium is a mineral that’s crucial for heart health, particularly for controlling blood pressure.

Bananas are rich in potassium, and increasing your intake of potassium-rich foods and cutting down on sodium can reduce your risk of heart disease by lowering blood pressure.

Bananas also contain magnesium, another mineral that can support heart health. Magnesium plays a crucial role in maintaining a healthy heartbeat and may also reduce the risk of heart disease in various ways.

5. Bananas are one of the best natural foods for endurance athletes

If you’re an endurance athlete, bananas are a great addition to your diet.

Not only are bananas easy to eat, but they also come with their own natural packaging – a banana peel, making them perfect for on-the-go.

The natural sugars in bananas – fructose, glucose, and sucrose – can provide a quick and sustained energy boost.

Combined with their high fiber content, bananas make an excellent source of fuel before, during, and even after a long workout, plus, eating a banana before a run can help maintain your blood sugar levels and prevent muscle cramps thanks to its high potassium content.

All this means that bananas are one of my personal go-to snacks that I eat before a long training run or race, as well as what I reach for while running trail half marathons, marathons and 50k+ ultramarathons to get a real-food nutrient and energy boost that’s easy to digest on the run.

Types of banana: a guide to the different forms of banana

Maybe you already knew about plantains… but did you know that bananas come in a variety of types, each with its own unique taste, texture, and nutritional content? Here are a few of the most popular types:

Cavendish Bananas: When you think of a banana, you’re probably thinking of the Cavendish. They’re the most commonly consumed bananas in the world. They are sweet, with a creamy texture and are often used in baking and cooking.

Plantains: These are not your typical sweet banana. Plantains are starchy, less sweet, and are usually cooked before eating, much like potatoes. They are popular in Latin American, Caribbean, and African cuisine.

Lady Finger Bananas (or Baby Bananas): These are smaller and sweeter than the typical Cavendish bananas. They are usually eaten raw and can be added to desserts for a more concentrated banana flavor.

Red Bananas: These bananas are sweet and creamy, but they have a slight raspberry flavor. They’re rich in vitamin C and potassium and are great for eating raw or using in recipes.

Blue Java Bananas (or Ice Cream Bananas): These bananas are sweet and creamy, with a taste and texture that’s reminiscent of vanilla ice cream. They’re great for smoothies or eating raw.

Manzano Bananas (or Apple Bananas): These bananas are sweet and tart, with a flavor that some say is reminiscent of strawberries or apples. They’re often used in desserts and smoothies.

Burro Bananas: These bananas have a square-ish shape. Their flavor is tangy and sweet, and the texture is slightly crunchy when they’re fully ripe.

How to select and store bananas

When buying bananas, choose fruits that are firm and free from bruises or other injuries.

If you want to eat the bananas within a day or two, select ones with more brown spots.

For later use, green bananas are a better choice, as bananas ripen quite fast.

Side effects of eating too many bananas

While bananas are packed with nutrients, eating too many bananas could potentially contribute to weight gain due to their high sugar content.

They may also lead to some digestive issues like bloating or stomach cramps, especially if you eat bananas every day in large quantities.

Can dogs eat bananas?

Yes, dogs can eat bananas in moderation. They are a safe and healthy treat when given in small amounts.

However, avoid feeding your dog banana peels as they can be hard for dogs to digest.

So there you have it, bananas are not just delicious they’re a powerhouse of nutrients that provide a myriad of health benefits. Whether you’re looking to boost your heart health, improve your digestion, or need a quick energy boost before a run, bananas have got you covered. Happy eating!
