Introduction:  

Pineapple is known to be the queen of fruits because of the excellent taste and refreshing flavour it bears. After banana and citrus, pineapple is considered the third most important fruit in the world. Pineapple is botanically called Ananus comosus. The taste and quality of pineapple juice depend upon the season, geographical areas, process and time of harvest. Pineapple fruit’s refreshing flavour and taste are contributed by the perfect balance between sugar and acid.^1,2 

The pineapple is a herbaceous annual plant that grows in tropical regions. The leading producer of pineapples are Brazil, Thailand, China, the Philippines, and others include India, Kenya and Nigeria. There are different varieties of pineapples, namely Honey King, Pernambuco, Giant Kew, Red Spanish, and Smooth Cayenne. Pineapples may be beneficial and used in the diet of people suffering from diseases. Pineapple juice is a fresh, concentrated liquid prepared from pineapple fruit pulp. It is a natural cocktail of beneficial enzymes, vitamins and minerals, which may make it a beneficial morning drink.^1–3 

So, read along to know more about the potential benefits, medicinal uses and side effects of pineapple juice on human health.

Potential Uses of Pineapple Juice: 

Pineapple residues left after the processing of pineapples may be of use as a preservative for food, cosmetics, and other therapeutical purposes. The pineapple waste is full of bioactive compounds like ferulic acid, vitamins A and C, saponins, flavonoids, phytosterols, tannins, and steroids.

Dr. Smita barode, BAMS

Pineapples are used in various foods. In many cultures, pineapple has been used for different potential purposes. The nutritional value and beneficial components of pineapple make them even more popular among people.² 

1. Potential Uses of Pineapple Juice for the Digestive System:    

Pineapples juice may be a digestive aid. It may have nutrients like carbohydrates, fibre, calcium, potassium, vitamin C and certain minerals that might help digestion. The main digestive enzyme, bromelain, may be responsible for breaking down the large protein molecules. It might stimulate digestion and enhance the functioning of the intestines. The detoxification activity of pineapple might help in clearing the microflora of the stomach and help in constipation.^1,3 

However, this information is insufficient. We require more studies to understand the potential benefit of pineapple juice in overcoming digestion problems in humans. 

2. Potential Uses of Pineapple Juice for Bones:  

Pineapple wastes are richly composed of lignin and cellulose, which are considered raw materials for paper production. Hence, pineapple waste which is otherwise cumbersome to dispose of could be a potential source of pulp and paper production, thus sparing the woods.

Dr. Anuja Bodhare, MD

The benefit of drinking pineapple (Ananas) juice is that it might help maintain bone health. Pineapple contains trace minerals like manganese, which may be responsible for forming bones and connective cells. The antioxidant properties of vitamin C may help in the formation of bone collagen, muscle, cartilage and blood vessels. Hence, pineapple juice may be helpful in building healthier, stronger bones and a muscular body. Drinking pineapple juice by older adults might help to strengthen their bones. It might also promote bone growth in young people.¹ 

3. Potential Uses of Pineapple Juice for Diarrhoea:  

Diarrhoea might significantly cause illness and death in children. Pineapple contains an enzyme called bromelain, which may be useful in diarrhoea. The primary pathogens responsible for diarrhoea produce toxins in the digestive tract, particularly in the intestines. The enzyme bromelain may have the ability to counteract these toxins. Pineapple juice might also stop the attachment of pathogenic bacteria to the surface of the intestine and might result in anti-diarrheal activity.^2,6 

These studies are insufficient and need more research to provide the effectiveness of pineapple juice in managing diarrhoea in people. 

4. Potential Uses of Pineapple Juice for Osteoarthritis:  

Pineapple provides more than the recommended amount of an essential yet trace element manganese. It is useful to boost your metabolism, response, and healthy bones.

Dr. Ashok Pal, BAMS

Some people experience severe joint pain, which might be related to osteoarthritis. Various research suggests that pineapple may have a pain-killing effect which might help relieve achy joint pain, similar to certain drugs used in pain. According to the research conducted by Akhtar et al., pineapple juice contains vital components that might enhance pain relief and decrease inflammation in the joints.^2,3 

However, these studies are not sufficient. Furthermore, research is needed to prove its extended use in osteoarthritis issues in humans. 

5. Potential Uses of Pineapple Juice for Tumours:  

Pineapple juice might show anti-tumour and anti-cancer activity. The enzyme bromelain may help to regulate the division and spreading of cancerous cells. The anti-tumour activity may be due to the anti-inflammatory properties of pineapple. One of the research on human cell lines (Chandler and Mynott, 1998) suggests the bromelain enzyme may have the ability to kill tumour cells.² 

These studies are insufficient and need more research to support the significance of pineapple juice in dealing with tumours in humans. 

6. Other Potential Uses of Pineapple Juice:  

• Pineapple juice might play an essential role in blood clotting.² 
• Adding pineapple to your diet may help to burn more fats.³ 
• Pineapple juice may be a great post-workout drink. Adding pineapple to your drink might help you overcome muscle soreness and aid in quick recovery.³ 

Though studies show the benefits of pineapple juice in various health conditions, this information is insufficient. Therefore, more studies are needed to establish the true nature of the benefits of pineapple juice on human health are necessary.
