A gastroenterologist advises seniors to avoid certain foods due to potential health risks. Grapefruit can interact with medications commonly taken by older adults. Raw eggs are a potential source of foodborne illness. Fatty, fried, spicy, and highly seasoned foods can irritate the stomach lining, which is more sensitive in older adults. Processed foods, such as canned goods and sausages, are high in salt and can cause edema. Sugary foods should be replaced with honey, dried fruits, and fresh fruits. Raw or undercooked meat, fish, and seafood should be avoided, as they can contain harmful pathogens. Raw eggs, especially, carry a risk of salmonella infection, which can lead to dehydration and complications in older adults.
