Nutritional Concerns in Older Adults Lead to Serious Health Issues
“1. Reduced Appetite & Unintentional Weight Loss Age-related changes in taste, smell, and digestion, plus dental issues and medications, often lead to eating less. This causes muscle loss (sarcopenia), frailty, reduced mobility, and loss of independence. 2. Inadequate Protein & Micronutrients Older adults need more protein but often eat less. Vitamin B12 absorption drops, and vitamin D/calcium intake is often low. Results: muscle wasting, weaker bones, fatigue, slower healing, and cognitive decline. 3. Dehydration Thirst sensation fades with age, and some avoid fluids due to incontinence concerns. Chronic dehydration causes dizziness, confusion, constipation, and falls — and often leads to hospitalizations that trigger further decline. References Bernstein & Munoz (2012).

Summary
Older adults commonly experience reduced appetite and unintentional weight loss, which are linked to higher rates of sarcopenia, frailty, and loss of independence. Inadequate protein and micronutrient intake in this population is well documented to cause muscle wasting, weakened bones, fatigue, slower healing, and cognitive decline. Dehydration is also prevalent, contributing to dizziness, confusion, constipation, falls, and increased hospitalizations that can accelerate overall decline.

This review summarizes recent papers enhancing our understanding of the incidence and prevalence of micronutrient status and protein-energy malnutrition in free-living older adults. Among older adults, the deficiency of protein, energy, and/or micronutrients contributes to various states of malnutrition that may result in a cascade of adverse outcomes.
- Malnutrition in Older Adults—Recent Advances and Remaining Challenges - PMC
Regarding the overwhelming evidence that protein requirements are higher in older age [65,66], adequate protein with appropriate energy intake is crucial in order to prevent malnutrition and sarcopenia. Further, due to the frequent micronutrient deficiencies in higher age, targeted supplementation of micronutrients might be useful, when diet alone is not sufficient to meet the age-specific requirements.
