Colon cancer is on the rise among people under 50, with no clear explanation. Dr. Neelendu Dey, a researcher at Fred Hutchinson Cancer Center, thinks gut microbes may play a role. The microbiome, comprising trillions of microbes, affects overall health and disease risk, including colon cancer.
Diverse gut microbes are linked to better health outcomes. A doctor’s unique gut microbiome is shaped by diet and environment. Ultra-processed foods and sedentary lifestyles can harm the gut microbiome. Dr. Dey follows a balanced diet rich in fiber, which feeds “good” bacteria in the gut, promoting diversity.
Fiber-rich plant-based foods like fruits, vegetables, nuts, beans, and oats are essential for boosting gut health. A 2018 study found that those who ate more diverse plant-based foods had healthier microbiomes. Dr. Dey often consumes Indian dishes containing lentils, chickpeas, and spices to achieve this diversity.
In addition to a balanced diet, regular exercise is crucial for maintaining good gut health. Exercise helps move food through the digestive system quickly, reducing exposure to toxins. Dr. Dey stays active by participating in soccer teams and exercising independently.
By understanding how individual microbes respond to different ingredients, researchers hope to provide personalized dietary recommendations to prevent precancerous polyps from forming. Dr. Dey’s approach emphasizes working with one’s microbiome, much like practicing a musical instrument daily.
