Poor gut health is linked to various serious illnesses, including cancer and cardiovascular disease. Maintaining a healthy microbiome, which consists of trillions of bacteria in the intestines, can mitigate these risks. Gastroenterologist Dr. Ronnie Porat Jankelson from Maimonides Medical Center in New York noted that a healthy gut contributes to easier weight management, reduced psychiatric disorders, and overall improved mood.

Experts recommend a diet rich in fiber and vitamin- and mineral-rich foods, which does not have to be expensive. Fermented foods such as yogurt, sauerkraut, and kimchi are beneficial for gut health, as they contain probiotics that help block harmful pathogens, according to researchers at Harvard Health. These items are also affordable: a jar of sauerkraut or kimchi typically costs around $4.
For those who may not enjoy sour foods, sweetened probiotic beverages like Yakult or Calpico can be a good alternative, offering greater probiotic benefits than regular yogurt at under $5 for a pack of five 2.7-ounce bottles. While not all yogurts contain probiotics, options like Icelandic Skyr yogurt or kefir are available for just over $2 per serving.
A diet abundant in various vegetables, fruits, and nuts is also beneficial and cost-effective. Nutritionists recommend daily fiber intake of 25-30 grams, with beans being a particularly excellent source. Canned navy beans and black beans contain 20 and 15 grams of fiber, respectively, priced under $2 per can. Other high-fiber options include peas, Brussels sprouts, and broccoli, with prices for frozen vegetables starting at 99 cents for a 12-ounce bag.
Fruits, particularly raspberries, are also high in fiber, with an 8-ounce container providing 16 grams for around $4. Pantry staples like green tea, which is rich in vitamin C and antioxidants, and black tea, noted for its polyphenols, support gut health. Additionally, coffee retains its antioxidant benefits regardless of whether it is caffeinated or decaf, though roasting can affect polyphenol levels. Dark chocolate is another sweet option that offers health benefits due to flavanols, which are antioxidants associated with reduced heart disease risk, according to U.C. Davis Health.
Staying hydrated is crucial for digestive health, as water aids in food breakdown and nutrient absorption. Exercise is also important, as it helps eliminate waste and bacteria, regulates digestion, and can improve sleep quality. Regular exercise can be as simple as walking or jogging, with benefits often observed within just 10 minutes.
Maintaining proper sleep, ideally 7-9 hours per night, plays a significant role in gut health, as the body repairs and builds the immune system during rest, as emphasized by Dr. Christina Lee from the Cleveland Clinic.
