Banana belongs to the Musaceae family in the genus Musa. The Fe‘i banana, which belongs to the Australimusa sub-section of the Musa genus, is cultivated mainly for its fruit. The Fe‘i bananas are categorised by straight bunches, pink-red to purple sap, and deep yellow or orange coloured fruit pulp. Banana and plantain are a group of large perennial herbs that can grow up to 20 feet.

An Overview of Banana

People cultivate bananas in the tropical region, with India being the largest producer with an average annual output of 14.2 million tonnes. Other leading producers of bananas include Ecuador, the Philippines, Brazil, Mexico, China, and Costarica. People also use the fruit, leaves, stem (also known as ‘false stem’), flowers, and banana tree roots as medicine. In North America, most of the accessible bananas are from one precise variety. However, many types of bananas exist around the world.

Banana is a wholesome fruit, and you can use almost every part of the tree for its medicinal value. For example, it helps maintain low potassium levels in the blood (hypokalaemia), constipation, and diarrhoea. People also use bananas to treat diabetes, high cholesterol, and many other conditions, but no detailed scientific research supports most of these uses.

Banana fruit contains chemicals and carbohydrates. Some of these carbohydrates work as fibres, which play an essential role in regulating the gastrointestinal system. The chemicals function as antioxidants which play a role in reducing swelling and fighting free radicals. Bananas also contain potassium, vitamins, and several other minerals.

Banana Stem – Here’s What You Should Know

The banana stem is not like other plant stems because the flower stalk of the banana plant is known as the banana stem. The thick stalks rise from the soil, thus forming the spine of the herbaceous plant. The banana stem has a crunchy surface and possesses a mild flavour when consumed as a food product. But, on the other hand, it is sweet and gives a bitter aftertaste. Therefore, it is fair to say that the stalk is the stem of the banana plant. 

The banana stalk harvests one colossal flower cluster and then dies. The stalk is generally cut off from the plant when the bananas are plump and subjected to the ripening process. Therefore, people consume this stalk as the banana stem.

Health Benefits of Banana Stem

The banana stem is loaded with an ample amount of fibre and is thus known to benefit in preventing constipation and ulcers in the long run.

The banana stem also contains a substantial amount of vitamins B6 and potassium. Hence, patients suffering from anaemia and diabetes are advised to include this food product in their diet regularly. Some of the other benefits of the banana stem are:

Prevents Diabetes

The prevalence of diabetes is witnessing rapid growth among low and middle-income countries compared to high-income countries. Rising cases of diabetes worldwide are primarily due to several factors such as obesity, sedentary & unhealthy lifestyle, and genetic history.

Vitamin B6 is a cofactor involved in many reactions responsible for modulating various functionalities. Therefore, deficiency of it often leads to several implications like Parkinson’s, diabetes, autism, cancer, and many more. 

Studies linking diabetes and vitamin B6 have correlated both complications and effectiveness. Studies in Drosophila have indicated that vitamin B6 deficiency may lead to diabetes. Hence, banana stems, a rich source of vitamin B6, are believed to produce effective results in combating diabetes. Furthermore, vitamin B6 in the stem supports the production of haemoglobin and insulin. 

People also use the stem for the treatment of hyperglycaemia. Lectin present in the banana stem stimulates insulin-like enzymes, which regulate the growth of fatty cells. Moreover, bananas stems are highly suitable for consumption among diabetes patients, owing to their low glycemic index.

Detoxification 

The juice of the banana stem flushes out toxins from the body. Therefore, it is also consumed as a drink by many. It has diuretic properties and positively affects the digestive system. It also has a lot of good fibre, which plays a vital role in maintaining optimum gut health.

Banana stem juice regulates the acidic levels in the human body and balances them. As a result, it helps to reduce heartburn and discomfort in the digestive system.

Reduce Weight

Banana stem juice is very beneficial in the weight loss process. The high content of fibre curbs hunger pangs and cravings, thereby reducing food intake and contributing to weight loss. The fibre also facilitates the release of sugar and fats into the body’s cells. If consumed as salad, the raw stem pieces help reduce obesity by cutting down on fat.

Prevents Kidney Issues

Currently, doctors often recommend including banana stem in the diet for patients who suffer from gall bladder stones. You can include banana stem in the diet as a beverage or part of a meal.

The stem juice is a decent diuretic drink and helps oust small kidney stones. If mixed with cardamom, this juice soothes the bladder and provides relief against cystitis. Cystitis is a form of urinary tract infection (UTI) that disturbs the bladder. It is more common among women. Cystitis generally heals by itself. However, in extreme cases, you would require antibiotics for its treatment.

Prevents Anaemia

According to WHO, in 2019, the global prevalence of anaemia stood at an overwhelming 29.9% among women in the reproductive age category or aged 15-49 years. Whereas anaemia’s prevalence among children aged between 6-and 59 months stood at 39.8%.

Banana stems are highly recommended in the treatment of anaemia by healthcare professionals. They are rich in vitamin B6 and iron, both known to promote haemoglobin levels in the blood.

Relieves Constipation

Subsequently, the plantain stem is full of fibre, which can effectively provide relief in constipation. Therefore, consumption in the form of juice for treating constipation is exceptionally beneficial. However, not straining the juice is recommended by experts to maintain optimal levels of fibre in the drink.

Reduces Bad Cholesterol

According to reports published by WHO, one-third of ischaemic heart disease cases globally are due to high cholesterol levels. In addition, high cholesterol levels are estimated to cause roughly 2.6 million fatal episodes yearly. Between 2015 and 2018, approximately 12% of American adults showed cholesterol levels higher than 240 mg/dL, says CDC.

The banana stem can also help efficiently manage cholesterol levels, among many benefits. It is a rich source of vitamin iron & B6, which play an essential role in increasing haemoglobin count and reducing low-density lipoproteins (LDL) cholesterol levels.

Regulates Blood Pressure

Hypertension or high blood pressure is when the blood pressure against the arteries’ walls is abnormally high. If left unadministered, hypertension increases the chances of stroke. According to CDC, approximately half of the entire American adult population, i.e., ~47%, suffer from hypertension.

Banana stems are rich in potassium, a mineral best known for combating fluctuations in blood pressure. Hence, regular consumption of banana stems can help manage high blood pressure effectively and reduces the risk of cardiovascular disorders.

Prevents Urinary Tract Infection

Studies have found that Urinary tract infection (UTI) is one of the most common infections that affect women worldwide. UTI often leads to vaginal infections, and it majorly results from pathogens that originate in the digestive tract.

Banana stem juice possesses diuretic properties. Thus, it aids the body in flushing away toxins and purifying the urinary tract. Therefore, it is best to consume banana stem juice at least three times a week to evade the chances of urinary tract infections.
