Quick Take
A video claims that a green juice can cure cancer and help with other health conditions too. We did the fact check to term it as Mostly False.
The Claim
A YouTube video claims that drinking a green juice containing cucumber, celery, apple, and spinach can cure cancer, lower blood sugar levels, reduce blood pressure, and lower cholesterol.
Fact Check
Is it true that green juice can cure cancer?
No, green juice cannot cure cancer. Green juices made from vegetables and fruits like cucumber, celery, apple, and spinach are rich in vitamins, minerals, and antioxidants. But, there is no scientific evidence supporting the claim that they can cure cancer. Cancer is a complex disease that requires treatments such as surgery, chemotherapy, radiation, and targeted therapies. Relying solely on green juice or solutions like fasting to cure cancer could actually delay essential medical interventions and make the prognosis worse.
A 2021 study reviewed dietary polyphenols, which are abundant in fruits and vegetables, and their role in cancer prevention. These polyphenols show promise in modulating cancer-related pathways and may work synergistically with conventional therapies. But still, they are not sufficient to treat cancer on their own. The study emphasises their role in supporting overall health but cautions against viewing them as substitutes for standard cancer treatments. Another study from 2018 on apple polyphenols found they could inhibit cell growth and metastasis in triple-negative breast cancer (TNBC) cells in laboratory settings. But, this does not translate into a cure for cancer.
Similarly, scientific evidence does not support claims that other natural remedies like alkaline water can cure cancer. These remedies can even be more dangerous if they lead patients to forgo proper medical treatments.
Dr Pooja Khullar, a Radiation Oncologist at Dharamshila Narayana Super Speciality Hospital in New Delhi, emphasises the importance of a holistic approach to cancer prevention. She says, “It’s essential to understand that no single food or exercise can fully ‘fight’ cancer. Effective cancer prevention needs a complete approach which includes a balanced diet rich in fruits and vegetables, regular physical activity, minimising exposure to carcinogens, avoiding smoking and alcohol, limiting direct sun exposure, and keeping up with regular medical screenings. I recommend focusing on an overall health strategy and seeking expert guidance from medical professionals.”
Dr P. Rammanohar, Research Director at Amrita School of Ayurveda in Kollam, cautions against depending on a single ingredient or solution to treat cancer. He explains, “Cancer is a complex group of diseases, and there isn’t a single cure for it. Different treatment approaches are designed for various types of cancer, and no single drug or remedy is effective for all forms of the disease.”
Why are green juices healthy?
Green juices are popular for their nutrient density. Ingredients like spinach and cucumber are packed with vitamins A, C, and K. They are also rich in minerals like potassium and magnesium. These nutrients are essential for maintaining overall health, supporting immune function, and promoting healthy skin, bones, and eyes.
A 2013 study highlighted the anti-cancer potential of cucurbitacins, compounds found in cucumbers. The study shows these compounds could inhibit cancer cell proliferation and induce apoptosis (cell death) in various cancer models. However, while these findings are promising, they do not suggest that consuming cucumbers or green juice can cure cancer. This is similar to claims that marijuana is better than chemotherapy, which also lack substantial scientific evidence and can lead to dangerous health outcomes.
Additionally, cancer research indicates that natural compounds found in fruits and vegetables, like those in green juices, may help reduce cancer risk. However, it is important to note that they are not effective standalone treatments.
How do antioxidants work?
Antioxidants are compounds that neutralise free radicals, which are unstable molecules that can damage cells. These molecules can contribute to the development of chronic diseases, including cancer. Common antioxidants include vitamins C and E, beta-carotene, and flavonoids.
A 2015 study on dietary fibre, abundant in fruits and vegetables, suggested that high fibre intake might reduce the risk of certain cancers, such as colorectal cancer. Meanwhile, another study from 2011 demonstrated the anti-cancer properties of glycoglycerolipids found in spinach, which could inhibit cancer cell growth. However, while these findings highlight the benefits of a diet rich in fruits and vegetables, they do not support the idea that these foods can cure cancer.
Moreover, a 2012 study showed that dietary spinach could suppress colon carcinogenesis by modulating microRNA profiles and other molecular pathways. This study underscored the potential of spinach in cancer prevention but did not claim it could cure existing cancers.
Dr Swati Dave, PhD in Food and Nutrition, Mumbai, says, “Antioxidants play a very important role in protecting our cells from damage due to free radicals. These are the unstable molecules that can lead to oxidative stress and contribute to chronic diseases, including cancer. By neutralising these free radicals, antioxidants help maintain cellular health and support the body’s natural defence systems. A diet rich in fruits and vegetables provides a good source of antioxidants. But still, it’s important to remember that they work best as part of a balanced diet rather than as a standalone solution.”
What are the recommended cancer treatments?
The recommended treatments for cancer depend on the type and stage of cancer, as well as the patient’s overall health. Conventional treatments include:
- Surgery: Removing the tumour and surrounding tissue.
- Chemotherapy: Using drugs to kill cancer cells or stop them from growing.
- Radiation therapy: Using high-energy radiation to destroy cancer cells.
- Targeted therapy: Drugs or other substances that target specific molecules involved in cancer growth.
- Immunotherapy: Stimulating the body’s immune system to fight cancer.
These treatments are supported by extensive research and clinical trials. For instance, a 2024 study reviewed the anticancer properties of spinach, highlighting the role of its bioactive compounds in inhibiting tumour growth in both in vitro and in vivo studies. While these compounds have shown promise in cancer prevention, they are not replacements for established cancer therapies.
Can antioxidants replace cancer medications?
Not really. A diet rich in antioxidants can support overall health, but there is no evidence to suggest that antioxidants can replace cancer medications. In fact, some research indicates that high doses of antioxidant supplements may interfere with the effectiveness of certain cancer treatments. This is especially true for those that work by inducing oxidative stress in cancer cells. Therefore, it is vital for cancer patients to consult their healthcare providers before making any significant changes to their diet or supplement regimen.
THIP Media Take
The claim that green juice can cure cancer is mostly false. Although green juices are healthy and packed with essential nutrients and antioxidants, they cannot replace conventional cancer treatments. Cancer is a serious disease that requires professional medical intervention. Incorporating green juices and a healthy diet into your routine can support your overall well-being. However, when it comes to cancer, it’s necessary to rely on evidence-based treatments. Always consult with healthcare professionals to ensure you’re getting the right care.
