Poor gut health has been linked to various diseases, including cancer, brain disease, and cardiovascular disease. However, a nutritious diet can significantly improve these health issues. A healthy microbiome, comprising trillions of bacteria in the intestine, helps mitigate the risk factors associated with these illnesses. Dr. Ronnie Porat Jankelson, a gastroenterologist at Maimonides Medical Center in New York, stated, "Once the gut is healthy, it’s easier to maintain a normal weight. There are fewer psychiatric disorders, and your mood would be better. There is less heart disease, just about anything.”

Experts recommend a diet rich in fiber, vitamins, and minerals, which does not have to be expensive. Consuming fermented foods like yogurt, sauerkraut, and kimchi introduces probiotics beneficial to gut health, according to researchers at Harvard Health. These probiotics help block harmful pathogens. Fermented products are generally affordable; a jar of sauerkraut or kimchi costs around $4. For those who dislike the sour taste, sweetened probiotic beverages such as Yakult or Calpico offer a significant probiotic boost, with a pack of five bottles costing under $5 and containing more probiotics than standard yogurt.
Not all yogurt contains probiotics, but options like Icelandic Skyr yogurt or kefir drinks can cost just above $2 per serving. A diet abundant in vegetables, fruits, and nuts supports good gut bacteria at low prices. Fiber from these foods nourishes gut bacteria, with nutritionists recommending 25-30 grams of fiber daily. Beans are particularly high in fiber; navy beans provide 20 grams per 15-ounce can, while black beans offer 15 grams at a similar price point. Frozen peas and broccoli are economical choices, with prices starting at 99 cents for peas and under $2 for broccoli, both containing nearly 20 grams of fiber per bag.
Fruits, especially raspberries, are also high in fiber, with an 8-ounce container containing 16 grams for about $4.
Pantry staples can further benefit gut health due to their antioxidant properties. Green tea is rich in vitamin C, boosting the immune system, while black tea contains polyphenols, significant antioxidants. Coffee, whether caffeinated or decaffeinated, also provides polyphenols, although the roasting process affects their levels; lighter roasts tend to have more polyphenols than darker ones. Dark chocolate is another enjoyable source of antioxidants, containing flavanols linked to a reduced risk of heart disease, according to U.C. Davis Health.
Hydration is crucial for digestive health, although the required amount varies by individual factors like height, body mass, and activity levels. Water aids in food breakdown and nutrient absorption, and it is cost-free. Regular exercise supports gut health by helping expel unwanted waste and bacteria and enhancing metabolism, which regulates digestion and gut bacteria. Physical activity can also alleviate sleep disorders that impact gut health and raise the risk of inflammatory bowel disease and colorectal cancer, as inflammation and microbiome imbalance can result from poor sleep. Simple exercises including jogging, walking, yoga, or cycling can provide gut health benefits within just 10 minutes.
Finally, adults should aim for 7-9 hours of sleep per night, as recommended by federal sleep standards. Dr. Christina Lee, a gastroenterologist at the Cleveland Clinic, noted that sleep allows the body, including the gut, to repair itself, break down waste, and strengthen the immune system.
