The present review examines the relationship between diet and frailty development and prevention. Frailty is a geriatric condition characterized by unintentional weight loss, low muscle strength, feelings of exhaustion, reduced physical activity capacity and slow walking speed.
Νutrition is a factor closely related to the frailty syndrome: all frailty criteria
are more or less affected by poor eating habits, whereas frailty itself may have a negative impact on eating and, thus, on the nutritional status. Research data suggest an association between frailty and specific constituents of diet, namely protein and energy intake, as well as intakes of specific micronutrients. Furthermore, healthy dietary patterns, such as the Mediterranean diet, have been linked to the frailty prevention.
