Deep dives
Importance of Protein for Older Adults
Protein intake is crucial for older adults, particularly in promoting muscle mass, strength, and function. Research indicates that approximately 50% of older adults fail to meet the minimum daily protein recommendations, which can lead to malnourishment. Increasing protein consumption may positively impact bone health by affecting insulin growth factor, which is vital for bone growth. Given that a significant percentage of older adults are not consuming enough protein, it is essential to encourage higher intake to improve overall health and potentially reduce osteoporosis risk.
