Higher diet quality has limited and inconsistent evidence for preventing declines in muscle strength and muscle mass in older adults.
While improving diet quality is crucial for physical mobility, its direct impact on preserving muscle mass and strength is less certain based on current evidence. Older adults should still prioritize diet quality for overall health, but should not rely on diet alone to prevent muscle loss; resistance training remains essential.
ModerateQualifiesMEDIUM confidence
There was limited and inconsistent evidence for a link between 'healthier' diets and lower risk of declines in muscle strength. There was a small body of evidence suggested a relationship between 'healthier' diets and better muscle mass outcomes.
Why this rating
The review explicitly states the evidence is 'limited' and 'inconsistent' for muscle strength and 'small' for muscle mass.
