Harvard-trained gastroenterologist shares 3 drinks that can help lower the risk of cancer

When it comes to cancer prevention, the conversation mostly revolves around lifestyle changes, regular screenings, and dietary habits. But according to Dr Saurabh Sethi, a Harvard-trained gastroenterologist, certain drinks may also play a meaningful role in lowering the body’s risk of developing cancer. While no single beverage can act as a magic shield, these drinks have been shown to possess anti-inflammatory and antioxidant properties. Here’s all we need to learn about what makes them special, and what the truth really looks like beyond the hype.

Green tea is often praised as a “super drink” because it is loaded with antioxidants like catechins, particularly epigallocatechin gallate (EGCG), which are believed to fight cell damage and reduce the risk of cancer.


​Studies suggest that green tea may slow the growth of certain cancer cells, especially in breast, prostate, and colorectal cancers. However, scientists caution that drinking green tea alone cannot prevent cancer. Its true benefit lies in its ability to reduce chronic inflammation and oxidative stress, two key triggers for abnormal cell growth. A warm cup of green tea daily can be seen as a gentle but consistent way to support the body’s natural defense system.

A blend of spinach, cucumber, celery, and ginger is promoted as a detoxifying drink that helps clear the body of toxins and lower cancer risk.


While “detox” is a word thrown around too casually, the real strength of this smoothie lies in its nutrient density. Spinach and celery provide folate and fiber, both linked to lower risks of gastrointestinal cancers. Cucumber adds hydration and antioxidants, while ginger brings in anti-inflammatory compounds such as gingerol. Together, they don’t just “detox” the body, they create an environment where healthy cells thrive and inflammation is kept in check. It’s less about cleansing and more about nourishing the body in ways that quietly protect over the long run.

Turmeric, thanks to its compound curcumin, has been hailed as a natural cancer fighter, and adding black pepper boosts its absorption in the body.


Curcumin has indeed shown promise in laboratory studies, where it slowed the growth of cancer cells and reduced tumor formation in animals. Black pepper contains piperine, which enhances the absorption of curcumin significantly. However, clinical evidence in humans is still evolving, and the effect is not as dramatic as social media often makes it seem. That said, sipping on a turmeric latte regularly can contribute to an anti-inflammatory lifestyle, and when paired with other healthy habits, it may quietly lower the risks linked to chronic diseases, including cancer.
