Colon cancer is increasingly being diagnosed in younger populations, a trend that health experts link to modern lifestyle patterns such as high intake of ultra-processed foods, low dietary fibre, chronic stress, poor sleep, and reduced physical activity. While screening remains essential for early detection, medical professionals emphasize that diet plays a key role in supporting long-term gut health and potentially lowering colorectal cancer risk.

A Florida-based gastroenterologist and health educator Dr Joseph Salhab has shared a set of everyday foods he personally consumes as part of a gut-friendly diet aimed at supporting colon health. He stresses that no single food can prevent cancer and that dietary choices should complement, not replace, routine medical screening such as colonoscopies.

One of the key food groups he highlights is cruciferous vegetables, including broccoli, kale, cabbage, cauliflower, and Brussels sprouts. These vegetables are rich in fibre and bioactive compounds that have been associated in studies with improved gut health and a reduced risk of colorectal cancer. He recommends consuming at least half a cup daily to support digestive function and overall colon health.

Another staple in his routine is a combination of yoghurt and oats, which provides a mix of probiotics, fibre, and essential nutrients like calcium. Yoghurt supports the balance of gut microbiota, while oats and other whole grains contribute dietary fibre that aids digestion and may help reduce cancer risk. He also includes tree nuts in his diet, noting that regular consumption has been linked in research to broader health benefits, including potential reductions in colorectal cancer risk.

Fruits such as kiwi, watermelon, apples, and citrus varieties are also part of his daily intake due to their fibre, antioxidant content, and digestive benefits. Apples, in particular, are highlighted for their pectin fibre, which may support gut health, especially when paired with spices like cinnamon. These foods are associated with improved bowel function and a healthier intestinal environment.

Avocado is another key component of his recommended diet, valued for its ability to support gut microbiome diversity and create a favourable environment for beneficial bacteria. According to his observations, avocados may play a role in maintaining overall digestive balance. He emphasizes that the broader principle behind his diet is not restriction but inclusion—focusing on fibre-rich, plant-based, and minimally processed foods that collectively support gut health and long-term well-being.
