Eating live microbes and its link to frailty in older adults: analysis of NHANES data (1999-2018)

AI simplified

Abstract

32.8% of older adults showed a greater than 0.21.

  • Older adults with medium dietary microbe intake had a lower prevalence of frailty (OR = 0.825) compared to those with low intake.
  • High dietary microbe intake was associated with an even lower prevalence of frailty (OR = 0.779) compared to the lowest intake group.
  • A significant non-linear relationship exists between dietary live microbe intake and frailty prevalence, with beneficial effects observed below an inflection point of 161.82.
  • Participants were categorized into low (33.5%), medium (47.0%), and high (19.5%) dietary microbe intake groups.
