[Nutritional problematic related to frailty and sarcopenia in older].

Introduction: frailty and sarcopenia are prevalent conditions in older adults which diagnosis and treatment often overlap. Objective: to analyze the nutritional problematic related to frailty and sarcopenia in older adults. Methods: a literature review, about particularities of frailty and sarcopenia, diagnosis and nutritional treatment, has been carried out. Results: frailty is a geriatric syndrome that can be identified by at least three of the following criteria: weight loss, exhaustion, reduced physical activity, increased walk time, low grip strength. Sarcopenia is a muscular disease characterized by low muscle mass and reduced muscle strength as the main determinant. Both conditions can benefit from adequate protein intake (1-1.5 g/kg/day) and regular physical activity. Conclusion: identification, prevention, monitoring and nutritional treatment of frailty and sarcopenia in older adults is important because of its high prevalence. The main goal is to maintain the muscular integrity and minimize muscle loss in older adults. A healthy aging includes regular physical activity and the fulfillment of the protein requirements of this population.
