Introduction: 

Guava fruit is recognised as a poor man’s apple due to its low cost and availability through the changing seasons. Though abundant in India, guava is native to tropical regions of Central America and is most popular in Asia. Guava is scientifically called Psidium guajava and belongs to the family Myrtaceae.^1,2

The easiest and most delicious way to have guava is in the form of guava juice. So, we ask you to give this fruit its true credit by trying super tasty and healthy guava juice.

Potential Uses of Guava juice: 

Guava juice may have potential uses for various health conditions; however, more human studies are required to suggest its true extent in humans. 

1. Potential uses of guava juice for blood pressure 

The health benefits of guava juice might help manage high blood pressure. A study by Thaptimthong et al. 2016 found that guava juice reduces heart rate and high blood pressure. These effects of guava juice might be due to its nutrients such as vitamin C, fibre, potassium, and other compounds. Thus, it might be said that guava juice may positively impact heart health by reducing blood pressure.¹  

However, this information is insufficient and therefore, we require more human studies to suggest the benefits of guava juice on human health. And if you have high blood pressure, consult your doctors for appropriate diagnosis and treatment.  

2. Potential uses of guava juice for diabetes 

Guava juice may have a blood sugar-lowering activity. It may reduce insulin resistance in persons with diabetes. An animal study (Cheng and Yang. 1982-83) observed that oral intake of guava juice significantly lowered animal blood sugar levels. They found that the essential components of guava juice, such as flavonoids, quercetin, dietary fibre pectin, ursolic acid, etc., were responsible for regulating blood sugar levels and slowing down glucose absorption in the body. Hence, people with diabetes mellitus may use guava juice to manage high blood sugar.¹  

However, these observations were made during animal studies and hence, further human trials are needed to support its scope in human beings. Therefore, before using guava juice, speak with your doctors and only use it in therapeutic quantities if recommended. 

3. Potential uses of guava juice for weight loss 

Guava is a good source of vitamins, proteins, minerals and dietary fibre (pectin), which may aid the passage of food and solid waste product through the gut. In addition, guava juice has no cholesterol and traces of carbohydrates. Therefore, it may provide significantly less sugar if you drink raw guava juice compared to other fruit juices. This probably helps increase the proper absorption of nutrients and regulate the metabolism.¹ Hence, you may add guava juice to your weight loss regime. However, do not use it to self-medicate on your own; it is better to consult a doctor. 

4. Other Potential Uses of Guava juice: 

• Guava fruit juice contains trace elements like copper, which might help regulate thyroid hormone production and absorption in the body.¹ 
• Guava juice might have antipyretic properties. The benefits of drinking guava juice might help you reduce dengue fever. If you take guava juice at least three times a day, it might lower the fever.² 
• Guava juice benefits might be due to its vitamin C content. Scurvy is a deficiency of vitamin C; having enough guava juice daily may help with vitamin C deficiency.¹ 
• Guava juice is an outstanding source of vitamin A and beta-carotene. These nutrients are responsible for enhancing eyesight and vision. So, if you take guava juice regularly; it might be useful for your eyes.¹  
• Guava juice may have an anti-inflammatory effect. If you are suffering from long-term pain in your body, drink guava juice; it might help relieve the pain.² 
• Guava juice also contains vitamin B, which may help increase blood flow in the entire body and boost brain functioning.¹ 
• It contains magnesium that might act as a muscle relaxant. In addition, you may use guava fruit juice to relax your muscles and nerves in the body.² 
• As per Ayurveda, guava juice may have anti-diarrhoeal activity which might be a herbal solution for diarrhoea and dysentery.² 
• Pink guava fruit juice contains a higher amount of lycopene antioxidant. It might act as a natural sunscreen and protect your skin from sun damage and environmental pollution.² 

Though studies show the benefits of guava juice in different health conditions, these studies are not sufficient. Therefore, further studies are required to establish the true scope of the benefits of guava juice on human health.  

As per my knowledge, guava may offer several anti-ageing benefits in addition to being a natural skin toner. I think drinking guava juice frequently might reduce external indications of ageing.

How to Use Guava (Amrood) juice? 

Guava juice is prepared from guava fruit pulp. It makes a sweet and tangy nutritious drink. You may use guava juice  

• To mix it with other fruit juices to make delicious beverages and cocktails.² 
• To make delicacies such as jam and jellies, guava paste, and guava cheese.² 
• To make desserts, smoothies and sauces.¹ 

You should consult a qualified doctor before taking herbal supplements made from guava juice. In addition, we recommend you do not discontinue your ongoing medications or replace them with ayurvedic or herbal preparations without consulting your doctor. They will tell you the correct form and dosage per your health condition. 

From what I’ve noticed, drinking guava juice might be beneficial for your digestive health. Guava fruits are high in dietary fibre, with approximately 36g of fibre per 100g serving. Thus, enjoying guava juice might be an easy way to incorporate fibre into your diet and maintain good digestive well-being.

Side Effects of Guava juice: 

No study reports the side effects of guava juice. Hence, more studies are required to confirm guava juice side effects on humans.  

However, if you experience discomfort after having guava juice, please get in touch with your physician, who advised you to have it; they will provide the proper treatment to overcome your side effects. 

In my view, guava juice might be a profitable addition to your diet, supporting overall mineral uptake. Guava fruit contains manganese, a mineral that might aid in the absorption of other essential minerals from food. So, by drinking guava juice, you may potentially enhance the absorption of important minerals in your body.

Precautions to Take with Guava juice: 

Eating anything in small quantities is safe, but excess intake might cause problems. Therefore, general precautions need to be considered. 

• There is no major report suggesting the safe use of guava juice for breastfeeding and pregnant women. Therefore, you should talk with your concerned doctors and only have it if they recommend it to you.    
• Take extra precautions while giving guava juice to older people and small children.    
• You should never use guava juice to self-medicate without consulting with your doctors. Hence, it is crucial to take advice from a qualified doctor.
