Micronutrients & recovery
Older adults with sarcopenia exhibit significantly lower dietary intakes of protein (g/kg), vitamin D, vitamin B-12, magnesium, phosphorus, and selenium compared to age- and sex-matched non-sarcopenic controls, despite having similar total energy intakes.
If you are an older adult experiencing muscle loss, strength decline, or functional issues, your diet likely lacks sufficient protein per kilogram of body weight and key micronutrients like Vitamin D, B12, magnesium, phosphorus, and selenium. Even if you eat enough total calories, the quality and specific nutrient density of your diet may be insufficient to support muscle health. Prioritize increasing protein intake and ensuring adequate intake of these specific micronutrients through food or supplementation, as these are commonly deficient in individuals with sarcopenia.
For similar energy intakes (mean ± SD: sarcopenic, 1710 ± 418; non-sarcopenic, 1745 ± 513, p = 0.50), the sarcopenic group consumed less protein/kg (~6%), vitamin D (~38%), vitamin B-12 (~22%), magnesium (~6%), phosphorus (~5%), and selenium (~2%) (all p < 0.05) compared to the non-sarcopenic controls.
Why this rating
Case-control study with matched controls, though observational and cross-sectional, limiting causal inference.
