Higher leucine intake is positively associated with grip strength in adults aged 19+ years.
Ensure your protein sources are rich in leucine (e.g., dairy, meat, eggs) as higher leucine intake is associated with stronger grip.

Grip strength increased (p < 0.05) with increasing quartiles of... leucine among all adults 19 + years (β = 1.33 ± 0.23...)

- Higher total dietary protein intake is positively associated with greater grip strength in adults aged 19+ years, with animal protein showing a stronger association than plant protein.Moderate
- Consuming more than 20g of dietary protein at two or more meals per day is associated with higher grip strength compared to consuming less than 20g at zero meals.Moderate
