Geriatric nutrition focuses on addressing the unique dietary requirements of older adults. As people age, physiological changes, including slowed metabolism, decreased appetite, and diminished nutrient absorption, can increase vulnerability to malnutrition and chronic illnesses. Research indicates that older adults benefit from diets rich in proteins, calcium, vitamin D, B vitamins, and omega-3 fatty acids, which support muscle maintenance, bone health, cognitive function, and immune strength. Specific dietary recommendations, such as including lean meats, dairy products, and fortified cereals, aim to address nutrient deficits commonly experienced in this demographic. Geriatric nutrition research also explores the impact of diet on age-related conditions like osteoporosis, arthritis, and dementia. Health professionals emphasize the importance of hydration, balanced meals, and potentially tailored supplements to improve overall quality of life and reduce the risk of hospitalization and other age-related health complications.
