Following UK diet advice linked to modestly slower strength loss
An observational analysis of up to 157,457 UK Biobank participants linked closer adherence to the Eatwell Guide with slower declines in strength and fat-free body mass percentage.
Our read
Populations- Studied:
- Cohort study of UK Biobank participants
- What changed:
- Grip strength declined more slowly with higher Eatwell Guide adherence scores
- The catch:
- Diet adherence scores relied on dietary recalls, which can misrepresent usual intake
- Why it’s aging research:
- It bears on staying healthy in midlife and later life.

In up to 157,457 UK Biobank participants, an observational study examined links between following the Eatwell Guide, the UK's healthy-eating model, and physical function. Researchers scored adherence using 24-hour dietary recalls. They examined associations at a single assessment and changes over follow-up.
Higher adherence scores were initially associated with stronger grip and a greater percentage of body weight that was not fat. Over time, higher scores were linked to modestly slower grip strength decline and a slower decline in fat-free mass percentage. Higher scores were also associated with greater odds of reporting a brisk walking pace, although this link weakened over follow-up. The association between higher adherence and lower odds of falls remained stable over time.
Why it matters
The study addressed whether national healthy-eating recommendations are relevant to limiting age-related functional decline. The authors said the findings support the Eatwell Guide's relevance to physical function in aging populations.
Caveats
This observational analysis cannot establish that following the guide caused better physical function. The abstract does not report participants' age range or the duration of follow-up.
