Whole foods are minimally processed and packed with nutrients, while processed foods high in refined carbs, saturated fat, and additives can increase the risk of digestive disorders. Food additives like glucose and salt may contribute to gut inflammation and impaired intestinal barrier function. Trans fats, found in some processed foods, are harmful to heart health and associated with an increased risk of inflammatory bowel disease. Artificial sweeteners can cause digestive problems and imbalances in gut bacteria. Diets high in nutrients protect against digestive diseases, making whole foods the best choice for optimal digestion.
