Quick Take
According to a Facebook post, an alkaline drink can effectively cure cancer. However, fact-checking reveals that this assertion is false.

The Claim
A popular Facebook post suggests that an alkaline drink prepared by infusing slices of cucumber, lemon, and carrot with mint leaves for 12 hours might boost immunity and potentially cure cancer and other diseases.

Fact Check
Does an alkaline drink have an impact on the body’s pH levels?
While the notion that consuming alkaline foods might make the body less acidic is gaining popularity, it lacks scientific validation. Alkaline water is just regular water that has undergone ionisation. This approach enhances its pH to between 8 and 9 when compared to normal drinking water. Supporters claim that the resultant preparation may:
- Neutralise excess acidity
- Optimise metabolism
- Improve overall systemic health
Even with these short-term advantages, these treatments might not be able to affect the pH of the body in any way. This is because, through intricate mechanisms, the kidneys and lungs regulate the blood’s internal pH between 7.35 and 7.45, which may not be altered by external variables, including a specific food or drink.
Alkaline water is safe for most people to drink, but the benefits it claims to offer are mostly exaggerated marketing tactics rather than clinically verified therapies.
In what ways do alkaline foods relate to cancer therapy? Is it feasible to rely on such options?
The term “alkaline diet” encourages consuming nutritious foods that are considered to establish an alkaline environment in the body while refraining from the intake of processed foods, meat, and sugar.
As was previously noted, the kidneys and lungs strongly regulate the body’s pH. Plant-based diets high in antioxidants, vitamins, and fiber may help lower systemic inflammation but are unable to effectively change systemic pH levels.
Furthermore, there is no empirical evidence that an alkaline environment prevents the growth of cancer. Therefore, while incorporating fruits and vegetables in one’s diet may help prevent cancer, it cannot be a primary approach for managing it effectively.

Dr. Manish Singhal, Consultant Oncologist at Apollo Hospital in Delhi, shared with THIP Media that cancer cells may create an acidic tumour microenvironment around themselves, which could aid in the growth and dissemination of the condition. Nutrition may affect overall health, but it has little influence on the acidity of the tumour microenvironment or the body’s alkalinity. These findings, however, are restricted to controlled settings and might not fully reflect the intricate workings of the normal human body. Furthermore, excessive alkaline conditions may impair the body’s normal processes and could potentially require hospitalisation.

This is further supported by Dr. Pooja Khullar, Radiation Oncologist at Dharamshila Narayana Superspeciality Hospital in New Delhi, who notes that certain studies have demonstrated that acidic environments stimulate the growth of cancer cells. Thus, a diet packed with alkaline foods (high pH) and low in acidic food items has been proposed to enhance the body’s alkalinity and prevent or even cure cancer.
Dr. Khuller points out that these studies, however, concentrate on cancer cells in a culture plate and fail to capture the intricacy of tumour behaviour in the human body.
Can the proposed preparation effectively cure cancer?
No, absolutely not. Contrary to common perception, a life-threatening illness such as cancer cannot be cured by an alkaline drink prepared with infused lemon, cucumbers, carrots, and mint leaves.
Given that the aforementioned ingredients are being considered for the management of cancer, an in-depth assessment is vital. We begin with the lemon slices, which are often rich in antioxidants and vitamin C, which promotes the immune system. Next are the carrot slices, which have antioxidant properties and are high in beta-carotene. Following them are cucumbers, which may provide hydration and dietary fibre. Finally, we explore mint leaves, which might exhibit modest digestive benefits.
While these nutrients might help the body when undergoing medical therapy and enhance overall systemic wellbeing, there is no substantial clinical evidence to support their use in both the prevention and management of cancer.
Is it appropriate to self-medicate for conditions like cancer? What are the risks of replacing conventional cancer therapy with unverified home remedies?
No, not at all. It is highly discouraged to self-medicate for severe medical conditions, including cancer. This is due to the fact that cancer is a complicated, progressing disease that requires tailored, evidence-based treatment strategies.
Based on the tumour or cancer type, stage, severity, genetic variations, and patient-specific factors, clinicians might opt for immunotherapy, chemotherapy, surgery, or a combination of these therapeutic approaches.

Dr. P. Rammanohar, Research Director at Amrita School of Ayurveda, adds more credence to this by emphasising that cancer is a complex disease that is challenging to manage. Distinct therapies need to be administered for each form, and these frequently include chemotherapy, radiation, or specific (targeted) medications.
All forms of cancer cannot be cured by a single herb or natural cure. While certain herbs have demonstrated potential in early lab studies, there isn’t enough solid evidence from human trials to consider them to be useful medications. Before trying any alternative remedies, it is imperative to speak with trained medical specialists and rely on established therapies.
Delaying or replacing conventional cancer therapies with unverified home remedies might worsen the disease’s progression, lower survival rates, and cause more complications. This could be particularly problematic when it comes to aggressive or advanced tumours, where timely and reliable intervention is essential.
Conclusion
Please be mindful that there are no scientific studies on alkaline diets that demonstrate their direct anticancer effect. Relying on such unverified preparations over established medical interventions cannot only be deceptive but may also be potentially harmful. Decisions about the management of illnesses such as cancer should only be taken after consulting with licensed oncologists. The approach would help maintain optimal outcomes, thereby ensuring safety without interfering with standard treatment protocols.
