Harvard doctor lists 6 cancer causing foods: What are their alternatives

Cancer is one of the most feared diseases of our time. While genetics and environment play a major role, everyday food choices also quietly influence cancer risk. In a video that is going viral on social media, Dr Saurabh Sethi, a Harvard-trained gastroenterologist, highlighted six everyday food items that science links to cancer development and progression. But here’s the eye-opener: reducing or eliminating these from the plate can have a serious positive impact on long-term health. Here are the 6 red-flag foods and what healthier swaps can nourish the body instead.Processed meats seen as protein-rich options. Some even view them as easier meal choices. According to the World Health Organisation, processed meats are classified as Group 1 carcinogens, meaning there’s strong evidence that they can cause cancer, particularly colorectal cancer. Dr Sethi warns that the nitrates and preservatives used in these meats can damage the cells lining the gut and promote cancerous changes.Swap ultra-processed meats with home-cooked lean meats like grilled chicken, or even plant-based protein sources such as legumes, and lentils. These options are less inflammatory and packed with fiber and antioxidants that protect gut health.Sugary drinks: Feeding cancer cells quietlyFizzy sodas and flavoured drinks are often considered quick sources of energy or mood boosters. Dr Sethi emphasizes that sugary beverages don’t just spike blood sugar, they also feed chronic inflammation and can accelerate cancer progression. Frequent intake of sugary drinks is linked to increased risk of obesity-related cancers such as breast, pancreatic, and colon cancers.Fresh coconut water, homemade fruit-infused water, or even simple herbal teas can quench thirst without the sugar overload. These also bring along antioxidants and hydration, both crucial for cell repair and immune support.
