Low vitamin intake is associated with risk of frailty in older adults

There is evidence that poor nutrition is related to frailty. Frailty is a clinical syndrome characterised by three or more of the following criteria: unintentional weight loss, exhaustion, weakness, slowness, and reduced physical activity. 

Frailty is produced by two pathways: First, resulting from age-related musculoskeletal changes, loss of muscle mass, and anorexia of ageing; and second, as a result of the effect of diseases.
