As we age, digestion naturally slows due to lower enzyme production, reduced stomach acid, and weaker gut motility. Foods like dairy, fried meals, red meat, and raw vegetables may suddenly cause bloating, reflux, or discomfort. Modern processed foods and artificial sweeteners can worsen symptoms. Instead of strict food restrictions, simple habits like eating smaller meals, choosing cooked foods, staying hydrated, and walking after meals can support digestion and improve gut health as the body ages.
