Description
Débora M Morais and four colleagues, publishing in 2026, test whether a urine marker of nitrate intake tracks with muscle strength. Nitrate, plentiful in leafy greens and beetroot, helps blood vessels and muscles work. Intake is hard to measure, though. So the team used urine levels from the national NHANES survey of 2011 and 2012. Their group held 1,301 adults, split at age sixty, and strength was the sum of both hands' grip.
Among the 399 older adults, higher urine nitrate went with modestly stronger grip, by two ways of scaling the urine measure. No such link appeared in younger or middle-aged adults, nor in the whole group pooled. The effect was small, so the authors ask for follow-up studies over time before anyone prescribes nitrate for aging muscle.
