What was done
This narrative review synthesizes age-related physiological and degenerative changes across major organ systems (including gastrointestinal, cardiovascular, musculoskeletal, and immune systems) and discusses dietary micronutrient requirements in older adults based on German Nutrition Society (DGE) reference values and disease-specific guidelines.
What was found
The abstract reports no quantitative data or numerical findings. It identifies vitamin D, vitamin B12, magnesium, iron, folate, and calcium as critical micronutrients that are frequently undersupplied in old age, noting that deficiencies in these nutrients can accelerate aging processes and impair immune, metabolic, and bone health.
Why it matters
It highlights key high-risk micronutrients to monitor in geriatric care and emphasizes tailoring nutritional intake to established dietary guidelines or disease-specific recommendations to help prevent or mitigate age-related chronic conditions.
Limits
As an overview/narrative review, it provides no original clinical trial data, systematic search protocol, or meta-analytic pooling. The abstract lacks quantitative estimates of deficiency prevalence or effect sizes for specific supplementation strategies.
