Sarcopenia is defined by the loss of skeletal muscle mass and quality of strength with aging, and is associated with frailty in older adults.
Not an actual disease, sarcopenia is part of the natural progression of aging. Healthy individuals, as they age, often have some degree of sarcopenia, however, there are ways to avoid severe progression of the condition, by way of diet, exercise, and other lifestyle choices.
A new study, very similar to another recent study on the effect of diet on frailty in older Spanish adults, looked at adherence to different diets on prevalence of sarcopenia in older Iranian adults.
300 Iranian adults aged 55 and older were randomly selected for this study, and were instructed to complete questionnaires related to dietary habits and patterns. Prevalence of sarcopenia was determined for each participant and compared to their responses on the dietary pattern questionnaires.
