Introduction: 

Most people are familiar with the traditional yellow banana, but very few know about its red-skinned cousin or the red banana. Red banana, also known as the Colorado banana, Musa acuminata Dacca banana, Cuban banana, red Spanish banana or lal Kela, originated in India and Southeast Asia but is now widely grown in the U.S., New Zealand, Australia and the Pacific Island. In India, these are widely grown in Karnataka and adjacent districts. The Kamalapur red banana variety is exclusively cultivated in Kamalapur village in Karnataka. They are available year around. Red bananas are soft and have a sweet flavour when ripe. In comparison with yellow bananas, these are sweeter and less acidic. This fruit has gained popularity because of its health benefits, which make it a great dietary choice. Let us read more about the health benefits of red bananas.¹

Potential Uses of Red banana for Overall Health 

Some of the potential benefits of Red banana are described as under:  

1. Potential uses of Red banana in Diabetes 

Diabetes (Type 1 and 2) is a metabolic disorder characterized by elevated blood glucose levels. Many anti-diabetic drugs act by inhibiting an enzyme (alpha-amylase) which causes a spike in blood glucose by converting carbohydrates into simple sugars. A study done by Adedayo et al. in 2016 found that red bananas may help manage type-2 diabetes by inhibiting the alpha-amylase enzyme. Also, red bananas have a low glycemic index which may positively impact diabetes. This indicates red bananas may help manage diabetes. However, more studies are needed to support these claims with greater reliability.⁷ 

2. Potential uses of Red banana in Breast Cancer 

Breast cancer is one of the most common cancers affecting women worldwide. Literature reviews support that dietary modification may help reduce breast cancer risk. Rusmiati et al. conducted a study to assess the anticancer potential of red bananas on breast cancer cells in 2021; the study findings stated that red bananas may help by stopping the growth of breast cancer cells. This effect is attributed to phytochemicals like tannins, flavonoids, saponins and alkaloids, which possess anticancer properties.⁸ Since, enough clinical evidence isn’t available to support these claims, it is best to take a professional opinion if you suspect breast cancer. 

3. Potential uses of Red banana for Hypertension 

Literature reviews support that dietary interventions may help in reducing hypertension or high blood pressure. Pelegrino et al. in a review in 2020 stated that red bananas are rich in potassium and magnesium, which may help relax the blood vessels and thus reduce blood pressure. This indicates that the consumption of red bananas may help manage blood pressure. However, there is a deficiency of research to support these claims.⁹ 

4. Potential uses of Red banana on Vision 

Age-related macular degeneration (AMD) is an eye disease occurring with advancing age that causes vision loss.  A review by Pelegrino et al. in 2020 showed that red bananas are rich in antioxidants like lutein and zeaxanthin, which protect the eyes from damage. This indicates that the consumption of red bananas may positively impact AMD. Additionally, being a good source of antioxidants like vitamin A, a component of a protein called rhodopsin, allows you to see in low-light conditions. Thus, red bananas may help improve vision. However, scientific evidence supporting these claims is limited. Therefore, we need more studies to support these claims.⁹ 

5. Potential uses of Red banana in Systemic Sclerosis  

Systemic sclerosis or crest syndrome is characterized by the hardening and tightening of the skin and internal organs like the lungs, blood vessels and digestive tract. This is caused due to the abnormal accumulation of a protein called collagen, which is found in the skin. Fruits that are deep red and green may help reduce systemic sclerosis due to the presence of anthocyanins, which help in reducing the accumulation of collagen. This indicates that red bananas may be able to help in systemic sclerosis. However, there is no scientific study done to support these claims.^{10, 11} 

6. Other potential uses of Red banana: ^{12, 13} 

• Red bananas, due to their high iron content, may help in managing iron-deficiency anemia. 
• Red bananas are rich in fibre, which helps in increasing satiety and reducing binge eating and thus, it may help in weight loss. Additionally, the presence of fibre in red bananas may improve digestive health and may relieve constipation. 
• Red bananas are rich in calcium and potassium, so they may help improve bone health. 
• The presence of antioxidants and vitamins in red bananas may help in blood purification. 
• Red bananas, a good source of vitamins such as Vitamin B6, may help boost metabolism as well as immunity.   
• The presence of potassium and magnesium may help the body to manage the effects of nicotine withdrawal, and make it easy for breaking the cycle of addiction.  
• Red bananas being a good source of vitamins such as Vitamin B6 may help in regulating menstrual cycle. The presence of potassium in red bananas may also help in reducing abdominal cramps during menstrual cycle. 

Though there are studies that show the benefits of Red banana in various conditions, these are insufficient and there is a need for further studies to establish the true extent of the benefits of Red banana on human health.  

Let’s talk about the potential of red banana as a nutrient-rich food! Researchers believe that due to the rich content of antioxidants, red bananas might be used as a functional food to provide additional nutrients and increase health benefits.

How to Use Red banana? 

• Red bananas are delicious when eaten fresh; cooking processes like baking and sautéing may enhance the flavor. 
• Red bananas can be added to desserts or paired with apples, berries, and citrus fruits in fruit salads.

You must consult a qualified doctor before taking any herbal supplements. Do not discontinue or replace an ongoing treatment of modern medicine with an ayurvedic/herbal preparation without consulting a qualified doctor.   

Red bananas may be used as a natural dye. Yes, recent studies suggest that other than its antioxidant and antimicrobial properties, red banana peels are believed to be rich in pigments such as flavonoids and hence might be used as a natural dye for food.

Side Effects of Red banana: 

• Priyanga et al. conducted a study in 2022 which showed that consuming bananas can sometimes result in banana allergy due to the presence of banana proteins which trigger an abnormal immune response.¹⁴ 
• Consumption of red bananas in excess can result in vomiting, bloating, flatulence, nausea, etc.¹⁵ 
• Additionally, an excessive consumption of red bananas will spike up potassium levels in the body and can result in abnormal cardiac rhythm (an increase in heart rate).¹⁵ 

However, if you experience any adverse reactions to Red banana, it is advised to discontinue its intake and immediately contact a doctor or your Ayurvedic physician who has prescribed it. They will be able to guide you appropriately for your symptoms. 

Precautions to take with Red banana: 

Consuming red banana is okay if taken in moderate amounts. However, general precautions must be followed in the following conditions: ¹³ 

• If you ever experience skin rashes, breathlessness or swelling after eating a red banana, there are chances that you may be allergic to them; it is advised to consult a doctor for proper advice. 
• Red bananas being highly nutritious are given to babies; it is advised to ensure that fully ripe and mashed red bananas without any lumps are used for easy swallowing by the babies.

Interactions with Other Drugs: 

• Red banana are known to cause a reduction in blood pressure, so if you’re on antihypertensive medicines, eating a red banana and your medications can cause your blood pressure to drop too low.  
• Red bananas due to high content of potassium can show a significant interaction with certain blood pressure reducing medicines (potassium sparing diuretics), which also increase levels of potassium in the body, which can result in an irregular heartbeat (arrhythmia) or an abnormality in kidney function. 

However, you must always seek the advice of your Ayurvedic physician about the possible interaction of Red banana with other drugs and follow the prescription thoroughly, as they will know your health condition and other medications you are taking.¹⁵
