Maintaining the health of the digestive tract is recognized as having broad implications for overall physical well-being. Experts suggest that specific dietary choices, particularly the consumption of highly processed and sugary beverages, may influence gut health. Gastroenterologists and registered dietitians have identified several dietary factors and mechanisms through which certain foods and drinks could affect the gut lining, microbiome balance, and systemic health.
Expert Insights on Gut Health
Pratima Dibba, M.D., a gastroenterologist with Medical Offices of Manhattan, has stated that compromised gut health can lead to systemic effects, impacting quality of life and potentially resulting in long-term complications. Lena Bakovic, M.S., R.D.N., C.N.S.C., a registered dietitian nutritionist at Live It Up, has also provided insights into dietary factors affecting gut health.
Primary Dietary Factors Identified
Experts, including Dr. Dibba and Bakovic, identify highly processed and sugary beverages, such as soda and energy drinks, as significant dietary factors associated with adverse gut health outcomes. Bakovic noted that regular sodas offer calories without nutritional value.
Dr. Dibba explained that processed foods, particularly acidic ones, may impair the gut lining. This lining functions as a barrier, absorbing water and nutrients while preventing toxins and partially digested food from entering the bloodstream. Damage to this barrier has been associated with conditions such as "leaky gut," which the Cleveland Clinic indicates may be involved in the development of various digestive conditions, autoimmune diseases, and metabolic disorders.
Bakovic added that foods high in added sugars can promote an imbalance in the gut microbiome, fostering the growth of potentially harmful bacteria. A study published in the journal Infectious Medicine linked an imbalanced microbiome to conditions including:
- Type 2 diabetes
- Obesity
- Non-alcoholic liver disease
- Cardiometabolic diseases
- Certain cancers
- Arthritis
- Depression
- Sleep disorders
- Hypertension
Research also suggests that artificial sweeteners may negatively impact gut health.
Role of Hydration
Furthermore, consuming soda and energy drinks may correlate with reduced water intake. A 2024 study published in iScience indicated that adequate hydration is essential for preventing digestive issues like constipation and for maintaining a balanced microbiome and a healthy immune system.
Additional Dietary Considerations
In addition to processed beverages, Bakovic and Dr. Dibba recommend limiting the intake of the following items to support gut health:
- Candy
- Baked goods
- Fruit juice
- Alcohol
- Spicy foods
- Excessive caffeine
