Green Apple: Uses, Benefits, Side Effects and More!

Introduction

The green apple is a hybrid fruit. It is developed by combining two different species of apple, namely, Malus slyvesterus and Malus domesticus. It contains bioactive compounds and flavonoids in a very good amount as compared to other varieties of apples. Green apples were first cultivated by an Australian woman named Maria Smith; hence, they are also known as Granny Smith apples¹.

This fruit appears light green with tart, juicy and crisp flavours and hard skin with a long shelf-life as compared with other apple types. Green apples are considered a healthy fruit and are used in weight management regimens due to their low calorie content and high dietary potassium and fibre content¹.

Properties of Green Apple

Apples are considered traditional fruits and consumed due to their nutritional properties, which are contributed by their bioactive compounds and dietary fibres³. The beneficial properties of green apples includes: 

• May have anti-pyretic (reduces high body temperature during fever) potential  
• May have anti-microbial (acts against microorganisms) potential  
• May help with anti-inflammatory potential  
• May be a potential antioxidant³  

Potential Uses of Green Apple

For many years, the traditional systems of medicine have been using apples in the management of various conditions³. Some of the potential uses of the green apple can be described as follows. 

1. For Cancer  

The green apple is rich in flavonoids that may help to reduce the risk of developing lung, pancreatic and colon cancer. Studies³ have also shown that green apples may have the potential to help with the growth of cancer cells in the breast, colon and skin. In clinical studies⁴, it has been shown that both males and females who consumed green apples in their diet had a reduced risk of developing lung cancer. However, cancer is a serious condition and would need a specialised doctor to diagnose and decide on treatment. It is important that you consult your healthcare provider before proceeding with any herbal remedy for health conditions.    

2. For Brain  

The extract of green apple juice may help prevent damage to the brain. An animal study⁵ showed that the animals fed with a green apple diet had increased levels of neurotransmitters, which act as signalling molecules of the brain. Research has confirmed that eating green apples, which are a high-fibre food, may help fight against brain diseases. Green apples also help in preventing the symptoms of Alzheimer’s and Parkinson’s diseases³. If you are suffering from any conditions or observe any symptoms related to brain function, make sure you talk to your healthcare provider about the risks and benefits of any herbal remedies.  

In my experience, consuming green apple juice, which is a potential source of Vitamin K, might have a positive impact on wound healing and repair. Vitamin K plays a crucial role in blood clotting and coagulation, which are essential processes for proper wound healing⁷.

3. For Asthma  

Consumption of green apples has been associated with managing many lung issues, including asthma. It has been shown that the intake of green apples reduces the incidence of asthma. A recent study⁶ in Australia showed that green apple intake decreases the risk of asthma and lung hypersensitivity. Another study with middle-aged men also showed a beneficial effect of apple consumption on lung functioning⁶. Asthma is a serious medical condition that requires you to follow your doctor’s advice and adhere to your treatment plan. It is advised that you consult your doctor before using green apples for its benefits for asthma.  

4. For Diabetes  

Eating apples daily may help overcome the risk of developing type 2 diabetes. Apples are full of soluble fibre and may play a key role in reducing blood sugar levels. A primary bioactive compound present in apple peels may also help to decrease the risk of diabetes. In clinical studies, it has been observed that consuming at least one green apple a day helps lower the risk of type 2 diabetes³. If you are suffering from diabetes, make sure you consult your doctor before making any changes to your diet.    

5. For Weight Management  

Doctors often recommend a high-fibre diet to improve and manage overall health. Apples are considered to be a high fibre food. Green apple has a high amount of dietary fibre, which is helpful for losing weight³. In a human study³, it has been shown that the consumption of green apples is associated with weight loss in middle-aged obese women. In a study⁴, people who consumed this fruit showed weight loss with reduced levels of blood glucose. If you want to lose weight, you can consult your doctor or nutritionist as they can guide you better about diet changes. Also, it is advised that you avoid making any major changes to your diet before consulting your doctor.  

6. Other Potential Uses of Green Apple  

• Green apples may act as an immunity booster and may also prevent the development of eye conditions.  
• Green apples might have a potential detoxifying ability and may help to detoxify the liver⁷, which in turn clears out the toxins from the body.  
• Green apples contain bioactive compounds which may assist in relieving pain⁷.  
• Green apple also has anti-inflammation properties⁷.  

Based on my experience, I have observed that consuming green apple juice might have positive effects on vision. The presence of Vitamin A in the juice has been known to support and improve eyesight. Incorporating green apple juice into your routine may help enhance your vision and contribute to overall eye health⁷.

Side Effects of Green Apple

There are some side effects of green apples related to teeth. The green apple is acidic and can cause demineralisation of the different portions of the tooth. The excess consumption of green apples may cause dental erosion (a chemical process that causes loss of mineralised tooth substance)⁸. Therefore, if you experience any dental problems, you must immediately contact your dentist. They will inform you about the various factors that cause erosion of the tooth.⁵ 

Natural herbs may have some allergic reactions and may react differently in different people. Always consult your doctor before including any fruit or vegetable in your diet for its benefits.  

Precautions to Take with Green Apple

Green apple is generally considered to be safe if it is taken in the recommended dosages. However, general precautions have to be followed while consuming a green apple. 

• There is not much information available on the safety of having green apples during pregnancy and breastfeeding. However, if any complications appear, consult your Ayurvedic physician immediately. 
• Since green apples are acidic, they might cause dental issues in children.⁵ Therefore, excessive consumption of green apples should be avoided. Contact your dentist if any dental problems occur. 

You must never self medicate, even with natural fruits, vegetables and herbs. It is advisable to consult your Ayurvedic physician for best advice.  

Interactions with Other Drugs

In clinical studies, it was shown that there is an interaction of the juice of apples with warfarin. Due to excess consumption of green apple juice, there is increased blood thinning that may result in an emergency situation⁹. Always disclose the ongoing treatments to your doctor, so that he can tailor a suitable prescription as per your ongoing treatment and conditions.  

Conclusion

From digestion to supporting weight management and potentially helping with conditions like diabetes and asthma, green apples pack in a surprising amount of goodness for such a simple fruit. While they aren’t a cure or a substitute for treatment, including them as part of your daily diet may offer gentle, long-term health benefits. As always, it’s best to speak to your doctor before making any dietary changes, especially if you’re managing a health condition.
