Older Adults' Nutrition and Early Health Warning Signs

Adequate nutrition is crucial for maintaining autonomy, preventing disease, and preserving quality of life in older adults. Unintentional weight loss is not a normal part of aging and may signal chewing difficulties, depression, medication effects, or other health issues. After age 60, protein intake becomes especially important to counteract reduced muscle‑building capacity and the risk of sarcopenia; sources such as eggs, lean meat, fish, dairy and legumes are recommended along with adapted strength exercises. Older people also experience a diminished sense of thirst, making dehydration a common hidden risk, so regular fluid intake from water, teas, milk, broths or high‑water‑content fruits is advised. A varied diet rich in fruits, vegetables, quality protein, whole grains and healthy fats supports muscle mass, immune function, bone health and cognition, while supplements should only be used after an individual nutritional assessment.

Memory lapses, unexplained weight loss, appetite changes, disorientation and mood shifts can be early indicators of cognitive disorders such as Alzheimer’s disease, as well as nutritional or chronic conditions. In Peru, the Ministry of Health recorded 13,067 Alzheimer cases from January to August 2025, with a higher prevalence among women. Dr. Ale Riofrío, a geriatric specialist, stresses the importance of comprehensive geriatric assessment—evaluating physical, cognitive, nutritional and functional status—to identify risks early and design personalized care plans, involving multidisciplinary teams of physicians, nutritionists, psychologists and therapists.
