TL;DR: Not only are bananas great for health, but they can also enhance exercise performance, improve recovery and help build muscle.

Almost all of you would have had a banana at some point. But did you know they can help you build muscle and improve muscle recovery?

I'll explain how bananas help to build muscle in this article and if you should have a banana pre and post workout.

Benefits of Bananas

Bananas have many benefits for muscle recovery and muscle building, such as those listed below.

A breakdown of each benefit is listed below.

Helps your body use protein better

Following a workout, it is generally suggested that you consume carbohydrate-rich meals, such as bananas, along with a source of protein, in order to assist your muscles recover more quickly.

Basically, the theory is that carbohydrates aid your muscles capacity to absorb and use protein, thus boosting the production of muscle and decreasing its breakdown. (1)

Recent research, on the other hand, indicates that this combination may not be required in the vast majority of instances.

Nonetheless, it is likely beneficial for most people, more research is needed to conclude anything though.

Helps replenish muscle glycogen

Eating carbohydrates after exercising stimulates the production of the hormone insulin.

Insulin aids in the transportation of sugar from your bloodstream into your muscle cells, where it is stored in the form of glycogen. (2)

It also aids in the development of more insulin-sensitive muscle cells, which makes it simpler for them to replace their glycogen reserves after exercise. (2)

The majority of individuals may completely replace their muscle glycogen reserves before their next activity by just eating a carbohydrate-rich diet, regardless of how soon they consume carbohydrate-rich meals after exercise.

Carbohydrate-rich foods, such as bananas, should be consumed as soon as possible after exercise. (3)

When you do this, you will be able to start your next session with completely or almost totally restored glycogen reserves, as opposed to when you do not do so. (3)

Helps reduce inflammation

Bananas, in addition to being high in carbohydrates, also contain significant quantities of useful chemicals such as dopamine and polyphenols (such as the polyphenol quercetin and catechin), among others.

The combination of carbohydrates and several other substances may be beneficial in preventing excessive inflammation after exercise.

This reduction in inflammation is believed to have the potential to facilitate faster muscle recovery after a strenuous bout of exercise. (4)

Improves heart health

Heart disease is the leading cause of early mortality.

Approximately 400mg of potassium is found in one medium-sized banana. Potassium is a mineral that is beneficial to heart health and helps maintain a normal blood pressure level.

Consuming around 1.3 grams of potassium daily is associated with around a 25% reduced risk of heart disease.

In addition, bananas contain various antioxidants which have been linked to a substantial reduction in the risk of heart disease.

Overall, bananas are a great food to help prevent heart disease.

  • Calories: 89

  • Protein: 1.1 grams

  • Carbohydrates: 22.8 grams

  • Sugar: 12.2 grams

  • Fibre: 2.6 grams

  • Fat: 0.3 grams

Water constitutes 75% of a banana.

Bananas are a good source of carbohydrates, which are found mostly in the form of starch in unripe bananas and sugars in ripe bananas.

Below is a list of the vitamins and minerals contained in bananas.

  • Potassium

  • Vitamin B6

  • Vitamin C

In terms of potassium, bananas are an excellent supply. Depending on the size of the banana, it may supply up to 33% of the recommended daily intake for this nutrient.

Bananas are also a rich source of vitamin C.

Other plant compounds found within bananas are as follows.

  • Dopamine

  • Quercetin

  • Catechin

Despite the fact that dopamine from bananas is an essential neurotransmitter in your brain, when taken or consumed, it does not pass the blood-brain-barrier to influence your mood.

When dopamine is consumed within a bananas it has an antioxidant effect.

Quercetin is another polyphenol found inside of bananas, it is a powerful antioxidant and anti-inflammatory compound with a multitude of benefits.

Bananas contain a number of antioxidants, another one being catechin.

Many health advantages have been associated with catechins, including a lower risk of heart disease.


Do Bananas Help Build Muscle?

Carbohydrates are great for replenishing muscle glycogen stores and increasing the energy available, helping you to recover from your workouts.

Consuming carbohydrates after a workout helps your body to utilise protein more effectively.

The plant chemicals quercetin and catechin can help reduce inflammation and improve post-workout recovery.

Quercetin has specifically been proven to improve endurance exercise performance.

This enhanced recovery, exercise performance and protein utilisation allows you to train harder and increase muscle growth.

Pre & Post-Workout

Bananas are a quick and rich source of carbohydrates and sugar. Sugar and carbohydrates provide a source of energy for your muscles.

Therefore eating a banana before a workout can help fuel your workout, allowing you to train harder.

Having a banana post-workout can improve recovery times and enhance muscle growth.

It can enhance recovery time by replenishing your muscles glycogen stores, reducing inflammation and enhancing the utilisation of protein for building muscle.
